Solar-powered Handbag 235

Posted by Hemos from the i-want-my-solar-man-purse dept.
karvind writes "BBC reports that a student, Rosanna Kilfedder, from Brunel University has designed solar-powered handbag to make finding keys and other items at the bottom of a bag easier. The handbag, dubbed Sun Trap, uses a solar cell attached to the outside of the bag to trap energy from sunlight. The energy is stored in an internal battery which lights up the lining. The lining is made from an electroluminescent material and is lit up by the bag's zip which acts as a switch. The bag goes dark when the zip is closed or after 15 seconds if it is accidentally left open. A secondary use of the portable battery is as an emergency charger for mobile phones and other wireless devices."

    Somehow I just don't see how adding a battery to a purse is going to make things easier to find. You know that women are just going to have one more thing in the purse to move around, and there's going to be too much in there for the light to actually penetrate... I mean seriously, most women I know have a double decker bus worth of stuff in there. It's a wonder they all don't lean when they walk. ;)

      Actually, I think it's somewhat surprising that a woman thought of this. To quote from the article: Safety and usefulness were uppermost in Rosanna Kilfidder's mind.

      Now if you look at handbags, they come in many shapes or sizes, but if you wanted to pick the two features which have the least bearing for handbag fashion, you'd probably end up with the two which Ms Kilfidder picked. :-)

      For clothing and accessories, people don't consider extra gimmicks like this, just like no-one buys jackets with integrated mp3 players. The focus for the design of these items is primarily to make the wearer look better. A slightly differently placed seam or the right label has a higher importance than some technology feature.

Maybe it is not as "sexy" as the bag in the article but it is simpler, cheaper, more practicle and more environmentally friendly (no solar cells and special linings). It is also more practicle in the sense that it will last just long enough until the owner drops it in favor of the latest fashion.

    This handbag isn't really inspiring or attractive, unfortunately. I suppose the technological appeal is present, but handbags do not sell on comfort (unless you shop at Walmart/Kmart, etc.) nor do they sell on technology. They sell due to designer, designer labels, and what the current trend is (think Louis Vuitton right now -- very, very popular).

    Her idea is good and well-intentioned, but a more couture-embracing design would be required to invoke a broader appeal. Put the idea in a beautiful handbag, and she may have something that sells well. But I'm beginning to think -- and see -- that many women are becoming very selective about which handbag they carry. The design of this bag doesn't look like one that could carry her idea well. Good thinking, though.

    Back in mid-2000 I helpd a friend of mine add a light to her purse. The lights activated via a small switch mounted on the strap. The lights themselves consisted of two led arrays, mounted on either side of the purse, about a quarter inch below the zipper (stitched into the lining, only the ligths were visible -- poking through "button holes" also stitched into the lining). The whole business was powered by a 9v battery located in a smaller inside pocket.
