Screwdriver
parametric modelling exercise

Project

MFA Advanced Product Design | Umeå Institute of Design | 2016 | 3 weeks individual project







Challenge

In this course, we focused on improving our modelling skills in SolidWorks as well as thinking about production aspects, such as injection molding, screwholes and electric circuits. Our task was to design a screwdriver for a brand of our choice that does not have any in their portfolio yet. I chose the brand POC.


Result

My final CAD-files are ready for injection molding, screwholes are implemented and there is enough space for all electric components. The prototype is fully working.
Moreover, we got an introduction into soldering and electric circuits.
For each phase of the project we got a certain amount of hours that I managed to stick to.




Design a fully working and producible screwdriver for a brand of your choice that does not have any in their portfolio yet

Screwdriver cover



POC - It's all about protection

The Screwdriver is made to be taken on trips. Since POC stands for protection, I designed a screwdriver cover. Instead of having to bring a whole toolbox, simply slide on the cover and you're good to go. In relation to POCs outdoor-sport section, this screwdriver is perfect to be used by groups on snowboarding-excursions.

Modelling in SolidWorks

I modelled the screwdriver, including the inner construction, in SolidWorks. I had only used the software in classes before. The modelling took me 32 hours in total and taught me a lot about SolidWorks modelling-strategies.

3D-printing and assembly

Afterwards, I 3D-printed the parts, assembled the screwdriver and checked if the technical components are working.
