The “EDAG Light Cocoon” evolves the idea of the bionically inspired body structure first introduced with the Genesis Concept, a form study that explores the possibilities of addictive manufacturing technologies.
This vision has been expanded into a full concept vehicle, which adopts a distinctive weatherproof textile outer skin, made of the outdoor textile “Texapore Softshell” developed by outdoor specialists Jack Wolfskin.
The skin gives a distinctive look as well as providing the required weather protection.
The exterior look is made even more unique by the backlight technology that illuminates the skeleton-like, organic structure beneath the outer skin.
This structure features an organic pattern designed for maximum lightness. EDAG’s engineers carried out static and dynamic calculations to define the basis of this topologically optimized ideal structure.
The combination of a thin outer skin and an underlying skeleton takes inspiration from leaves and their inner structure with a lightweight outer skin stretched over it.
The resulting graphic theme also reminds of the patterns that are adopted today by many architects who use generative modeling techniques and that are mostly derived from the Voronoi diagram , a mathematical partition which is frequently found in nature.
From the official Press Release:
“We are pursuing the vision of sustainability – as demonstrated by nature: lightweight, efficient, and without any waste,” explains EDAG’s head designer, Johannes Barckmann.
“The result: the ‘EDAG Light Cocoon’ presents a stable, branch-like load bearing structure from the 3D printer, which only uses material where it is absolutely necessary.”
EDAG CTO Jörg Ohlsen explains: “Even if it sounds futuristic to begin with, this approach has a its own special appeal: weighing no more than 19 g/m², the Jack Wolfskin material supports maximum lightweight design requirements with minimum weight.
“To give you a comparison: this extremely strong material is four times lighter than standard copier paper.”
“Combined with the topologically optimised, additively manufactured structure, it offers enormous potential and stimulus for the ultimate lightweight construction of the future.”
