task: applying formal language
supervised by Ute Peppersack
squareone internship, 2020
tools: Pen & Paper, 3D-printing, SolidWorks, Keyshot
squareone has developed a cross-product design language for SW Stahl's automotive tool portfolio. As part of my internship at squareone, I was able to participate in the redesign of the product portfolio and transferred the developed design language to the metal file line.
task
The task was to apply the developed design language to the ergonomic requirements of a metal file. The shape and details were designed in such a way that they favor an optimal hand position and formally align with the design language.
process
At the start, different handle shapes and contact points were examined by analyzing the status quo and competitor products.
Based on the findings, variants were sketched in cross-section and basic shape and then roughly implemented in CAD. To validate these, 3D print models were created and tested by different people.
details
Adapted to existing form elements, the handle has been extended to include a finger recess for the thumb or index finger. In combination with the overstretched rectangular cross-section and the bulge in the palm area, this ensures a firm grip.
As with the existing product family, the hole and chamfer on the top of the handle make it easy to hang up.
