Work Concept

What we need at school or at travel destination is a mobile booster. We designed a booster in the motif of springs, using cell-phone to resemble a tin toy. We hope to make charging cell-phone a fun activity.

Judges' evaluation

It has a distinctive shape of a wind-up of a spiral spring. The vision of GUI together with product design which reminds us of different senses such as strength, loveliness and nostalgia was recognized. In terms of commercialization, the relationship between the size of built-in battery and power voltage will need to be discussed further. Although there is a mechanical hurdle to be cleared, it will be great if the winding-up motion can be also achieved.
