Power drill for smaller hands

The power drill project consists of the development of a new power drill design proposal. The tool is thought to satisfy the need of a user with smaller and weaker hands, for women. Scientific papers have supported that power tools for women should be design specifically for them. With a view to do a product as ergonomic as possible, I used ergonomic tools and analysis. Not only the ergonomic aspects but also the aesthetics and the quality of the surfaces were important. Therefore, I designed a CAD model and then some renders and animations. To obtain a more realistic view of the product a physical prototype was developed with the real colour and finishes. What was the reason why I decided to design this power drill? What if a woman in her 60 wants to do some carpentry work? She doesn’t have a tool available power full enough to do the job but also that fits its measurements correctly. After performing some ergonomics analysis on previous designs, it was found out that most of the power drills are heavy and have a big handle for which small hands were difficult to fit well. For this reason, it was decided to design a power drill with a smaller handle and lighter weight. The first step was creating an initial designed which was later tested with questionnaires. From that feedback I modelled some handles in clay to find which one was more comfortable for my user group. Together with the information from a database I defined what my final design was going to look like. A real size prototype was developed, together with digital renderings, a poster, and a video animation. To exhibit the product the project also consisted of an A3 poster and an oral presentation.
