Autodesk redesigned iconic Scandinavian design chair achieving 18% less volume; 90% decrease in max displacement; and 79% in von Mises stress with generative design model

Autodesk redesigned the iconic Danish design chair by Hans Wegner to optimise its cost, development time, material consumption, and product weight. A generative design software, Dreamcatcher, was fed with the original design and produced thousands of variations which it then tested against the desired criteria. The final product benefits from 18% less volume; 90% decrease in max displacement; and 79% in von Mises stress, while it maintains its aesthetics.

Project Overview

Autodesk redesigned the iconic chair by Hans J. Wegner" Chair JH503, The Round Chair, with leather upholstered seat, 1950. Design Hans J. Wegner.
The company "decided to freshen it up a bit and optimize it in terms of cost, development time, material consumption, and product weight - while preserving aesthetics and comfort.

To do this, a design inspired into Wegner’s original was fed into software called Dreamcatcher. From a seed design, algorithms generated thousands of variations and subsequently tested them all to find one that optimizes the wanted parameters.
Software was subsequently applied in a similar way to optimize production.

Reported Results

"The result was the Elbo Chair: 18% less volume, 90% less bending of the wood when you sit in the chair, and 79% less von Mises stress – in other words a lot more equal distribution of weight when you sit in the chair."
