SUMMARY:Computational Design of a Kit of Parts for Bending Active Structur
 es
DESCRIPTION:Technical Papers\n\nQuentin Becker, Uday Kusupati, Seiichi Suz
 uki, and Mark Pauly (EPFL)\n\nBending-active structures are composed of el
 astic elements that deform to achieve a desired target shape. To support e
 ffective design, inverse algorithms have been proposed that optimize the g
 eometry of each element specifically for each design. This makes it diffic
 ult to reuse elements across designs or gain efficiency in fabrication thr
 ough mass production.\n\nWe address this issue and propose a computational
  framework to rationalize bending-active structures into a sparse kit of p
 arts. Our method solves for the optimal part geometry such that multiple i
 nput designs can be faithfully realized with the same kit of parts. Assign
 ing parts to different assemblies leads to a combinatorial explosion that 
 makes exhaustive search intractable. Instead, we propose a relaxed continu
 ous optimization incorporating a physics-based simulation in its inner loo
 p to model the elastic deformation of the bending-active structure accurat
 ely. Our algorithm allows analyzing different design trade-offs of a kit o
 f parts to tune the balance between fabrication complexity and fidelity to
  the original designs. We demonstrate our method on three different classe
 s of bending-active structures, showcasing the effectiveness of our approa
 ch for part reuse and sustainable practices in fabrication-driven design.\
