Title: Design of Deployable Structures Based on Geometry and Biomimetics

Abstract This research investigates deployable structures that can be compactly folded for transportation and storage and expanded to form spatial configurations. To address challenges such as material interference due to thickness, fabrication complexity, and construction safety, three fundamental operations—folding, cutting, and weaving—are identified and systematically applied as design strategies. Drawing on biomimetic principles inspired by insect hindwings and fungal net-like structures, the study develops geometry-based design models for each operation. By integrating geometry, biomimetics, and deployable design, this research demonstrates new possibilities for architectural deployable structures.

発表タイトル： 幾何学および生物模倣に基づく展開構造物の設計

要旨： 本研究は、運搬・収納時に小さく折りたたみ、展開によって空間を構成する展開構造物を対象とする。部材厚みによる干渉や施工の複雑性といった課題に対し、「折る」「切る」「編む」という三つの形態操作を整理し、それぞれに対応した設計手法を提案した。さらに、ハサミムシ後翅やキヌガサタケ菌網などの生物構造を模倣し、幾何学的条件に基づく設計モデルを構築した。これにより、展開構造物の新たな設計可能性を示す。

Abstract: The (classical, balanced) Wasserstein-p distance can be used as a measure of how close a source and sink mass distribution (with equal mass) are. In recent years, the Wasserstein-2 distance has been employed in the temporal regularization of dynamic inverse problems. The so-called Benamou–Brenier formula states that it can be written as the square root of the performed physical work through the transport from the source to the sink. In my talk, I will instead focus on dynamic inverse problems regularized with Wasserstein-1 transport. The Wasserstein-1 distance can be interpreted as the optimal transport cost with respect to the Euclidean distance: it equals infπ R |x−y|dπ(x, y), where measure element dπ(x, y) indicates the (infinitesimal) amount of mass moving from location x to y. I will explain a novel dynamic inverse problem on time-parameterized curves in the induced Wasserstein-1 (metric) space. It is a natural extension of static sparse optimization problems such as lasso or TV regularization. One essential difference to classical regularization with Wasserstein-2 transport is that it allows for discontinuous decision variables (realized as BV curves). Despite this weak regularity requirement and the non-differentiability of the cost function (x, y) 7→ |x − y|, it is possible to prove the existence of a sparse solution and its characterization. I will present this result. Further, I will detail an adaption of the fully-corrective generalized conditional gradient method to the problem and highlight a natural discretization approach. Finally, I will show some numerical examples. Joint work with: Marcello Carioni
