The main aim of the course was to learn Solidworks, with additional focus on branding and styling. The class were given a low cost grass/shrub trimmer, which was to be taken apart, inspected, and then the inside parts transferred into a new design. A suitable brand had to be chosen, analyzed through a brand board and then a new design was to be created with the original components in mind. Everything was modelled in Solidworks and finally 3D-printed .

This was made during the Visual Storytelling Course, separately from the design and manufacturing of the model.

BRAND BOARD  |  1,5 HOURS

Since its foundation more than 90 years ago the company has grown from a one-man business into a global chainsaw and outdoor power equipment manufacturer. Innovative ideas, in-house know-how and meticulous craftsmanship have resulted in a broad and steadily expanding product portfolio.

14 hours
The time limit for the course was 80 hours, thus only 14 went into ideation.

iterative process

Ideation was a back and forth process with several foam mock-ups, and measuring and re-measuring of the original components.

tolerances

To ensure that everything would fit, all the original components were measured, built in Solidworks and finall placed inside the new shrub shredder design.
