Design Brief: Preh


An ergonomic cutting tool for small vegetables


People preparing vegetables or fruit


Ideation, user testing, prototyping, and foam modelling


Ideation was used as the first step to understand ergonomic and balanced forms. Drawings were then scaled and used later for working prototypes.

User Testing

Users were asked to try both works-like and looks-like prototypes and evaluate them on a series of standards - fit, function, and form

Users were asked to cut small vegetables with various models and evaluate their level of motion and emitted force exerted on the cutting tool



Further testing concluded which form users preferred based on fit, appearance, and usability

Foam Prototypes

Prototypes were made to gain a better understanding of form, size, and fit.

These models were eventually used for user testing and further ideation
