Thanks, Elizabeth- you are being subtle saying sometimes it's the best way. Recall the old adage, 'Necessity is the Mother of Invention'. I think the best ideas always come from a direct need, or targeted challenge. Too many good designers are locked into company jobs, supporting corporate mandates to simply update a product line. That gets stale.
Yes, JimT, the contest was sponsored by a foundation for cerebral palsy--yes, it may seem unlikely but in some of the writing I've done I've found it is the people who have a medical need who actually are inspiring innovation these days. I wrote a story about an MIT program that paired doctors with students to come up with medical devices to solve real problems they encounter: http://www.designnews.com/author.asp?section_id=1386&doc_id=259900
So it may seem unlikely but perhaps sometimes it's the best way to develop targeted technology that can be put to practical use.
Excellent points, Battar. I think you'd be right about the weatherproofing. Maybe in a future design this problem could be tackled. I think maybe because the user is in Turkey, rain wouldn't be such a big issue? Seems to be a lot more sun than rain in that country...but I'm sure it's still a concern.
This "Change My World in One Minute" competition is exactly what I was suggesting. Although' I didn't catch who sponsored the competition. The Cerebral Palsy Foundation-? An unlikely Champion of the mentorship effort!
I'd define it as this chair has to be whereever the operator is and wants to be. It has to navigate like a normal chair but with the advantage that when out and about it is self sufficantly powering itself, increasing the range, speed, and thus the self sufficancy of the operator.
This is an exercise in material science, not electrical engineering. Using solar power to keep batteries charged in a mobile device is hardly news. But for this device to be practical it has to out in the sun (and rain, sometimes) to ensure a constant charging supply, and it has to not fall to pieces on the 1st of September after the raindrops have trickled through the non-stainless steel screws and the sunshine has baked the non-UV resistant plastics.
Weatherproofing the device is the bigger challenge.
A photo of the retracted panels would be good. As viewed it looks like an erector set project.(As an Erector Set past user this is not detrimental ccmment.) That would all be aceptable if the panels and frame colapse into the foot print of a wheel chair as a retractable car roof does. Good application of Solar. My opinion this would be a good starting point for the size of an electric car. Add only what is necessary from there to achieve distance, weather protection, speed, etc. Imagine a auditorium parking lot with hundreds of wheel chair sized vehicles.
Ahan Elizebeth that really great it feels very good watching young engineers inventing such technologies .Solar power wheel chair is simply very creative idea it helps give patients mobility but i have one question ? Are these wheel chairs folding if yes then it is very easy to use them during travelling if no it will be very difficult for user to buy another one for the purpose of travelling .
Thanks, MyDesign. I do find these stories some of the more interesting ones to cover as well. I've written about energy-harvesting soccer balls for underdeveloped nations and mobile app-driven prosthetic legs that help amputees get some of their normal lives back for Design News...this is the kind of stuff that shows some of the true promise of technology.
I think that's why there are batteries as well, far911, so that should help augment when there is no solar energy. But even under cloud cover I think some solar panels can still absorv and use solar energy. And yes, the panels can also serve as an umbrella!
What should be the perception of a product’s real-world performance with regard to the published spec sheet? While it is easy to assume that the product will operate according to spec, what variables should be considered, and is that a designer obligation or a customer responsibility? Or both?
Biomimicry has already found its way into the development of robots and new materials, with researchers studying animals and nature to come up with new innovations. Now thanks to researchers in Boston, biomimicry could even inform the future of electrical networks for next-generation displays.
