Hold-open clip for gas.
There safety hazards are obvious (although I can't recall ever hearing of anyone getting injured at a gas station, was/is it common at all?). However, surely there is a cheap design that can sense (most likely mechanically) that everything is "safe"

Human Factors in Design
Something I have come to realize is that human factors does not seem to get the use it deserves. This is not to say it is completely ignored; some Researchers and Industrial Designers have some exposure to human factors. They will use height charts, design for 5th percentile female to 95th percentile male, and other general best-practices. My gripe is that there are so many studies (See HFES journal, and/or ergonomics in design) containing mounds of data regarding posture, grip force, materials handling capacity, etc. that just get ignored.
I am fully aware that every designer cannot get another degree in human factors, but can d-schools not focus more on it in their curriculum? I had a colleague who got his ID degree from Va Tech, and didn't even know who Karl Kroemer was! (I am sure that most if not all of you reading this don't know either, but if you are interested in Human Factors he is an excellent place to start)

Disrupting "waste by design"
The cop out is "companies are built around selling completely new devices, so 'reusable' doesn't mesh well". I wonder, has anyone looked deeper than this refrain? Perhaps consumers (ugh) would buy 3 or more of these decorative shells ($$) in the same timespan in which they would have suffered with their old, unisghtly device before throwing it away? That would surely offset the cost.
The first company to incorporate such a model into their business would surely gain the much sought after disruptive advantage

Synergy of design for disassembly and shock
Just think of all of the different products you use in your life that can experience shock (from dropping?) on a regular basis...
TV Remote
Any other remote control for that matter
Xbox controller
Cordless Phone
Hair Dryer
Calculator (I'm a nerd)
every children's toy ever made (it seems)
Cell phones
Whether dueit is unscrewing half a dozen screws on the small remote or trying to crack open the ultrasonic weld on your cell phone, the disassembly (and consequently recycling) of these products can be prohibitively labor intensive.
We are better than this. I am convinced that it is doable to concot some clever geometry (a variation on the good old snap latch) that enables a device to withstand necessary shock while remaining easily disassembled. It is not a tough balance to strike, it is just that we are used to seeing things fastened with a safety margin of roughly 2 gazillion. We can afford to bring that down.
My remote control has 6 screws keeping the two halves together. These screws assure that the plastic shell will crack from shock before it pops in half. However, it is overkill. This small device doesn't need 6 screws. Think critically, what kind of shock is a remote control going to encounter? It will encounter point forces along its body, but what is the likelihood of it striking in such a fashion that the two halves of the remote attempt to rotate about each other like the hands of a clock? Furthermore, even if this unlikely even happens, surely the forces can't be much greater than 20 lbs (an estimation, but I feel comfortable with it. Slap an accelerometer on your remote if you don't). The point I'm driving at is that with some cleverly designed snaps, a remote control could withstand the forces it encounters in its lifetime while still being able to be twisted apart in one motion at its end-of-life.
So what is the takeaway here? Fasteners and ultrasonic welding are a cop-out. Be clever.

Blacktop Turbine
Everyone knows that in the summer, blacktop pavement gets unbearably hot. So much that if you were to find yourself in a large parking lot sans the foot covers, you would surely be quickly moving across the blacktop to the nearest patch of grass. Why not try to recoup some of that energy?
One option would be for large complexes like malls and stadiums to (the next time they repave) lay down a network of tubing (aluminum? cheap cost for the thermal conductivity) and pave over it.Then, when the air inside the tubing heats up and expands, it rushes to the exit (most likely located centrally, in the stadium, mall, etc.) and power an engine or turbine. The energy created by this would most certainly not power an entire mall, but would be a nice subsidy that could pay for itself within a few years.
The primary problem I see with this is maintenance. In order to ensure good heat conductivity, the blacktop should be in contact with the tubing. This prevents any easy fixes as the blacktop would have to be chipped away to gain access. (Although like any other problem, this can be dealt with)

Increase your fuel efficiency, burn less calories through hypermiling
Hypermiling has been around forever, its just a new name. For those of you who don't want to read the article, hypermiling is just tweaking your driving habits to increase gas mileage. Most of us have already heard of this, and just don't do it. Personally, I never adopted it because slowing down and driving with more patience (especially on the southeast expressway) has not been worth it. But with gas going where it is, the thought of a 35% increase in gas mileage (thats right, 35%) just might be worth it. In reading this however it got me thinking about cycling.
In the fitness obsessed world that we live in, people are always counting calories (energy) so that they look good naked, feel better about themselves, or whatever other personal goals they may have. It is to the point where I'm sure that somewhere, someone has affixed a calorie counter (typically found on stationary bikes) onto an actual bicycle. They are probably doing it to see how many calories they burn while they are working out. But what if burning calories wasn't the goal? For those commuting to work by bike in the morning, they might just want a lackadaisacal ride to work, not a calorie destroying sweat-festival. I say, why not try personal hypermiling?
Also, this form of hypermiling cuts the waste out of the workout, allowing the user to perfect technique. Sounds like an awfully valuable tool to someone training for endurance. Gotta perfect that waste-less cycling motion
Solar Panel System Design
Relative to our homes, the sun moves in the same path every day. Sometimes it is blocked by clouds, but regardless, the angle will be the same. Why then are all of the residential solar panels I see fixed? The only reason I can think of is that the energy required to move the panel itself is larger than the gain resulting from an optimized angle. For a poorly designed system, I believe this to be true.
For a home with a prismatic (triangular) roof, the peak can be used as a fulcrum on which the solar panels can be placed. Stabilizer pistons can attach each end of the solar panel to the roof (by placing the pistons at the end of each panel, the moment about the fulcrum will be maximized, giving us the most bang for our back regarding force). The energy required to move the panel would be minimal as is the nature of a fulcrum.
There are obviously several details to flesh out, such as the orientation of the house, the aesthetic, weather, etc. But giving the cost of energy, having a simple optimized system installed could be big business. It's my guess that the installation of solar panels will eventually be the wheelhouse of your local HVAC specialist or carpenter, and the first company to create a cost effective way to install a simple and efficient system would surely prosper

A rant on anthropology in Design
- It seems every anthropologist, anthropology student, or book on anthropology I read refers (directly or indirectly) to the stigma that is attached to applied anthropology. As Patricia Sutherland puts it, "the label 'applied' was stigmatic". As an engineer, this irks me. I define engineering as applied science. The physicists, materials scientists, biologists, chemists, etc. do the research that gives the engineers the tools to develop solutions. Correspondingly, those anthropologists who have a distaste for the field of applied anthropology are discouraging the use of the anthropological tools that could affect great change in the world.
- I had a debate in my ethnography class the other day. It was regarding whether or not "social sciences" such as anthropology are "real" in the sense that natural sciences such as biology, chemistry, etc. are. We debated this for a bit and then it dawned on me, "What a stupid conversation this is". Fighting over a naming convention for a field? It is ridiculous! Who cares if some people call your field a science or an art? Let the results of the work done in your field speak for itself.
- Lastly, Patricia Sutherland points out that in 1971, the American Anthropological Association (AAA) drafted the Principles of Professional Responsibility that prohibited anthropologists from undertaking research that could not be openly published (read: "Any commercial endeavor"). Imagine if the reigning professional association for any other profession gave a similar dictum, nothing would get done ever.
Thats all I got, hopefully I will write again before the month is out.

Drawing Blood
First off, let me clarify that I have been posting with less frequency lately not because I see no problems with the world, but because my "capstone" (read: Senior) design project is the development of a new technology for prosthetic ankles, and it is a time suck. However, today I find myself on the train, with some time to kill.
My son goes to the hospital with regularity and thus so do I. One of the things he needs to get done frequently is have his blood drawn so that they can run tests. Being the small boy that he is, the nurses can have difficulty finding a vein. This leads them to poke him several times (heartbreaking), and when that doesn't work, they end up calling a "drawing blood" specialist. Keep in mind this isn't a backwater hospital with untrained people, this is Children's Hospital Boston, which I believe is ranked as the 2nd best Children's hospital in the country.
I don't know enough about the fine mechanics of drawing blood to be able to redesign it here, but the procedure of "tying-off" one's arm in order to get a vein to show seems barbaric. If there is currently a better design out there, why is it not being used by the nurses at Children's Boston?
If there is a device out there (which I am not sure of), I imagine the reason it does not get widespread use is that it has too much visible technology or is too intimidating to use properly. What is needed is a device that looks simple (even if the behind the scene technology is complex), has a short learning curve, and takes the "art" out of the science of drawing blood.

Wipe-Free Glasses
I wear glasses about 90% of the time. They are comfortable, and I like the flexibility of being able to take them off when I read. The problem I get is dust. Over the course of the day, little bits of dust get on my glasses, at some point, the dust has accumulated enough to affect (minutely, but noticeable nonetheless) my vision clarity. To get rid of the dust I typically wipe it off on my shirt. The problem with this is that some shirt materials wipe better than others, you may have touched your shirt with your fingers, in which case the oil from your hands which is invisible on the shirt, will become visible on the glasses. Once there is a smudge from oil on your glasses, its game over until you get to go to the restroom and wash them off with water.
Below are some solutions to this problem, and my explanation why they aren't good enough.
- Use Contacts
- When I wake up in the morning (especially after I stay up late, which I do OFTEN), it can be slightly painful to put in contacts, as my eyes have not had sufficient time to "wake up"

- Get Lasik®
- I have always been a little hesitant about Lasik®, and it did not get better the other day. I am taking a Musculoskeletal Biomechanics course at Northeastern University, and the professor (a proud glasses patron himself) has done research on the eye, and is thus familiar with Lasik®. He told us that Lasik is not based on any biological sort of equation. It is an art, not a science. As such, its replicability is lower than it could be. In light of this information, my hesitancy regarding Lasik® has turned into a firm opposition

- Carry around a special cloth that I use to wipe my glasses.
- There may be some people whom can handle this, but it is not for me. I want a design that does not require me to take anything extra with me.

One idea I have is to use some sort of electrostatic property to make the glasses themselves repel dust. If there is no dust, there will be no wiping. If there is no wiping, there will be significantly less smudges and consistently better clarity.

Empathetic Design
I'm on the subway on my way to work this morning and arrive and Downtown Crossing (where I switch from the orange to the red line). As I get off the train I can hear the music of some subway performer. As I walk past the musician I recognize him. Turns out he is a guy I used to go to high school with, Andrew. We talked for a few minutes and apparently he still lives in our hometown and when he isn't playing coffee shops and the like, he comes to Boston to make a little extra cash on the side. Interesting, I thought. We talked for a few minutes about trivial things and then I got back on my way to work, and he got back to his.
As I'm waiting for the red line train, I run into my company's administrative assistant (who also waitresses at an upscale restaurant in Cambridge at night), who is also on her way to work. I have talked with her here and there, but never at any great length about anything. We spent the 30 minute journey to work talking about (what else?) work. The interesting stuff came when she started to tell me about why she is working as an administrative assistant there. Turns out she has a degree in teaching and interior design, but wanted to get into product design, and figured that an administrative job at the company would be a great way to learn about the industry. Go figure.
The reason that I am sharing these two encounters is that they display how different people's lives are. I know, "Duh". But for me, I understood this fact only at a macro level, not at a micro level. I mean, I knew our lives were different in some ways and similar in others, but I really couldn't articulate what those were. I feel that many of us fall into the same trap. It's likely considering that 90% of our interactions are with similar people, be they friends, family or coworkers. Stepping outside of this comfort circle of contacts and trying to understand someone different from you requires actual work, but it can be an enriching experience; enriching in the sense that by being empathetic towards others you can see the world through a different set of eyes. Let me tell you, when your profession/passion is designing products, services, or experiences for others, that empathy an invaluable tool. Unbeknownst to me, being my ambivalence towards learning about others lives on anything deeper than a superficial level was wasting a golden opportunity to exercise my empathetic muscle.
Well here is my resolution: make a conscious effort to understand the details of the lives of others, so that I naturally empathize with others. There is no doubt in my mind that this understanding will lead to higher quality designs that accurately addresses the issues that the user faces.
A Critique of the Dyson® AirBlade


I was killing some time at Logan Airport the other day, waiting for my brother's delayed flight to arrive. I had a drink at the bar and (consequently) went to the restroom. After handling my business I noticed something rather attractive on the wall. It was the new Dyson® AirBlade hand-dryer. I had seen some pictures of it on a few other blogs, but was still a little surprised to actually see it in front of me. Needless to say I washed my hands (quickly, as the anticipation of using this thing was akin to a child at 5:00AM on Christmas morning waiting for his parents to wake up) and scooted over to the Dyson®. The following are the takeaways (both good and bad) from my experience.
We'll start off with the good, because I'm a positive guy
- The device is attractive, a quality that sets apart from most other hand dryers.
- It uses technology similar to that used in industrial settings (air knives can be used to remove moisture from bottled beverage containers)
- Its automatic…which is good
Now a few not-so-good notes
- The device is appropriate for a certain height person. If you are too short you need to cock your elbows to get your hand in the slot.
- The air-knife is not as powerful as I expected. Thus when compared to a traditional hand dryer, I did not notice an improvement in the dryness of my hand or the time it took to get that way.
- However, the air knife is powerful enough that its initial burst can cause your hand to contact the appliance. One could argue that all of the hands that use this are freshly clean, but there is still something about touching things in a public restroom that seems unclean.
- Not incredibly intuitive. This is admitted by Dyson itself by their inclusion of a diagram on top of the device. I don't know who said it first, but they said it best: "Labels/Instructions are indications of design failure. "
Suggestions
- Make the user interface with the device through the front as opposed to the top. This would mean that shorter people do not need to reach over anything.
- When you lift your hands from your sides, your palms naturally face each other, not the floor. The design should reflect this, NOT require the user to adapt to the device.
Overall, I was disappointed. What was a great opportunity to redesign something that has been ugly and inefficient for years was squandered by designing something that was pretty and inefficient.

Baby Monitor Volume Control

For once this is me actually lauding a design. There is nothing obviously outstanding about this monitor. In fact, the best thing about it is a simple decision that requires no technological innovation whatsoever. It is the volume control. At first glance, it may just appear to be a regular scroll wheel… because it is! The only difference is that it is set up in reverse, so that when it scrolls down, the volume increases. The reasoning for this is that parents like me hear the baby crying and reach over to look at the monitor. This is an arduous movement considering that its 3:30AM and we're averaging 4 hours sleep over the past week. Often times we won't grab the monitor cleanly, and the hand will accidentally slide down over the volume scroll wheel. Now, if this were a standard volume scroll wheel (which it would be were it not for the designer who came up with this idea), I very well might mute my sons screams and go back to bed. This would be nice initially, but at best I would wake up feeling like crap, and at worst I could be ignoring the screams of a child who is in genuine distress.
Just goes to show that designing around the user's real-world activity can result in the little changes that will make a world of difference.

The Problem With Malls
It is not that I don't enjoy the utility of having so many stores in one place, it is definitely convenient. It's just that it is not an enjoyable experience for me. I don't like all of these advertisements telling me what I need to buy, I don't like the people in the booths trying to sell me something, I just don't like it. I would much prefer to buy things online. The only exception being a big-ticket item such as a thousand dollar TV, in which case I need to see it in person.
On the other hand, there are people who would live in the mall if they could. These are the people who have been hanging out in malls since they were 13. They love buying things, and when they run out of money, they look at things they want to buy.
I believe that these two groups of people make up the majority of a mall's customers. The latter will go to the mall no matter what happens. Thus, malls should focus on making the whole mall experience more enjoyable for the customer who doesn't like what's going on. I'm thinking adding a few cafes or some open sitting areas (instead of the uncomfortable benches).
I am sure there are many things that malls could do to make the experience more enjoyable. Whatever changes are made, the result must be to make the mall a desitnation for people other than the dedicated mall rats. If malls dont make these changes, then one day, after it has become unfashionable for 13 year old girls to spend all day at the mall, they will cease to exist.
Bottom line malls, get better

Ineffecient ATM
I think they should redesign the ATMs so the money comes out last. Someone might forget a receipt or their card because they do not go to the ATM for the explicit reason of getting a receipt or getting back their card. Whatever the percentage of people who leave their card in the machine is, I would bet that the percentage of people who would walk away without the money (the sole item that they went to the ATM for) would be orders of magnitude less

Portable Cupholder
I take the commuter rail every day into Boston. It is about 45 minute or so ride. One of the things I noticed today is that about 40% of all the riders have some type of beverage with them. Some of them are in some sort of reusable Thermos, but most are Styrofoam/paper cups from Dunkin Donuts or Starbucks. The Thermos owners can just close their cups, and then it doesn't matter if it tips over, but what of the coffee-house patrons? It is interesting to watch them try to unfold the Globe or Wall Street Journal while they balance their cup between their legs, between a leg and an armrest/wall, or on top of a bag (it seems almost everyone on commuter rail trains carries a bag of some sort). This is definitely a problem that people have become accustomed to dealing with, but I believe that it can be solved by design.
I imagine a mechanism, something small enough to be able to fit in your pocket, or the smallest pouch on your backpack/satchel/laptop bag. This mechanism would somehow adhere (suction cups?) to a surface. A pulling motion away from the adhered surface could then secure the adhesive seal while opening up a cupholder.
My mechanism might be (probably is) flawed, but I do believe that there is a need for this problem to be solved. Thoughts…?

EasyRead Watch
I was flipping through a Human Factors book today. Work was a little slow, so I figure I'd brush up on my wrist-mechanics seeing as handheld products are a big part of our business. The part that caught my attention was the section that went into details about what angles are appropriate for repetitive tasks. This got me thinking about what repetitive tasks do we aside from the much talked about typing, mouse clicking etc.? I am sure you can think of a million, but the one that hits home with me is looking at my watch.
I love my watch. A few times a year I will leave the house in a rush and forget my watch. These days are when I notice my obsessive time-checking habits the most. When I'm wearing a watch, every time I look at it my mind works something like this…
I wonder what time it is, I guess I'll look at my watch. (Rotates wrist)
Ah, 1:34. (Turns wrist away)
This is a pretty mundane, forgettable experience. Now compare to the days when I forget my watch.
I wonder what time it is, I guess I'll look at my watch. (Rotates wrist)
AHHHHHHHHHH! WHERE IS MY WATCH?!
Oh yeah, it's at home.
As you can see that is a much more memorable experience. One of the days that I left my watch at home I counted my mini-freak outs. Over the 12 hours I was away from home, I checked my watch 60ish (tough to keep count all day) times.
Now, I am not sure if 60 times a day is enough to put the "R" in RSI (Repetitive Stress Injury), but for the sake of my idea, I am going to assume it is …
I am not sure how this would be built, but I imagine a watch that displays the time to the user regardless of the position of the user's wrist. I have thought about filling it 90% with fluid, and using the resultant air pocket (which would always stay on top of the water, regardless of orientation) to contain some sort of e-ink display, but that doesn't seem too robust. Anyway, I'll kick the thought around a little bit, and if I come up with anything, it will be up here.

Ergonomic Water bubbler
I came to realize, I despise the water cooler. You have to stay bent over for (depending on your container) 15-45 seconds. This can cause a little bit of stiffness in the back, especially if you have been spending most of the day sitting in a chair.
I knew there must be a reason that every water cooler in the world had been designed with such a blatant disregard for human physiology.
Luckily , my boss had worked on developing a water cooler for pur. He enlightened me as to the nature of my dilemma. The reason you cant move the dispensers up while keeping the water container stationary is that the dispensers must stay below the bottom of the container as the flow always goes from top to bottom. The reason you cant raise both the container and dispensers is that the higher the container, the more difficult the container is to replace, the more likely spills are to occur.
My solution is fairly simple. Springs. Have the container rest on springs so that as water drains, the container becomes lighter, and the springs displace the container higher (F=kx baby). This way, you can ensure that the water level stays above the higher placed dispensers.
Stupid idea? Please tell me. These things just come and go

Traffic cruise control
There are several perils of the stop-and-go traffic situation. You can zone out and tap the car in front of you, you can just tweak out from stress (have seen it happen myself), or your leg can cramp up from repetitive stress.
My solution is a sort of slow-speed cruise control. You can have a laser distance sensor that can interpret how fast you are closing the gap between yourself and the car in front of you. This data can be transmitted to a regenerative braking system (always incorporate energy efficiency where possible), which will slow you down at the appropriate rate. The data will then be used conversely to smoothly accelerate you to an appropriate speed. The cycle continues all while your legs are resting stationary on the floor

Tupperware is a mess
This just came to me today, so I have not put a whole lot of thought into the mechanics or aesthetic of what it should look like. However, a quick web search gave me a picture of what it should NOT look like.
Anyway, just wanted to get that thought out there. Also, the "stackable" Tupperware is no good. I tend to stack Tupperware in my fridge, and they tend to collapse slightly when stacked. There are other complaints on different review boards, but I don't much feel like getting into them. Back to the Pats-Ravens game.

Cold weather workout
It led me to think, why dont they make a heating/cooling patch (much like they put on newborns to regulate their body temperatures) marketed at these outdoor excercisers. This way, they could go from a warm house, to a cold environment to a warm house, all without (literally) breaking a sweat.
