HandleLock

Untitled-2

The HandleLock was created to provide a solution to the complications of carrying a bike lock around. Some of the main difficulties came from interfacing a lock and handle together. The HandleLock was my original idea and four other members joined my project idea group and my job was to be the head project leader and lead designer/manufacturer/engineer. We ended up winning the most innovative product and had the third highest profits out of all other products.

Prototype:

Created out of PVC and 3D printed parts.

With our prototype, we did several prototype tests on the bicycle riders around Penn:

Test 1: Do bicycle users find the product easy to use/would they use the product?

Audience: Frequent bicycle users around Penn.

Method of testing: We gave our prototype to 5-6 frequent users of bicycles around campus. We explained the prototype and the product, then observed them as they used it.

How we measured results: We made observations and took notes on each user as they used the product; additionally, we asked users directly for their initial thoughts and comments about the product as they used it.

Feedback from audience: Because of the flexible nature of the prototype (e.g. separate parts of the lock tend to swivel a little bit), some users found it difficult to take the two separate handlebar segments and attach them together to form the lock. Other users noted that they typically did not use the curved style of bicycle handlebar and would like to be given the option to choose the type of handlebar to use.

Test 2: Is our product/prototype close to the ideal weight, length and size of handlebar and lock?

Audience: Focus group of frequent bikers around UPenn.

Method of testing: We gave our prototype to 5-6 frequent users of bicycles around campus. We explained the prototype and the product, then observed them as they used it.

How we measured results: As with test 1, we conducted observations on each user as they tested our product, took notes on any difficulties encountered, and listened to feedback and comments from each user that we interviewed.

Feedback from audience: Feedback varied. We ultimately concluded that the ideal weight, length and size of handlebar and lock was largely based on personal experience and preference, though it became clear that people of different heights and sizes tended to have different needs (e.g. tall vs. short people).
