  • Computational Design of 2D Lattice Structures Based on Crystallographic Symmetries
    Item type: Journal Article
    Leuenberger, Alfred; Birner, Eliott; Lumpe, Thomas S.; et al. (2024)
    Journal of Mechanical Design
    The design representations of lattice structures are fundamental to the development of computational design approaches. Current applications of lattice structures are characterized by ever-growing demand on computational resources to solve difficult optimization problems or generate large datasets, opting for the development of efficient design representations which offer a high range of possible design variants, while at the same time generating design spaces with attributes suitable for computational methods to explore. In response, the focus of this work is to propose a parametric design representation based on crystallographic symmetries and investigate its implications for the computational design of lattice structures. The work defines design rules to support the design of functionally graded structures using crystallographic symmetries such that the connectivity between individual members in a structure with varying geometry is guaranteed and investigates how to use the parametrization in the context of optimization. The results show that the proposed parametrization achieves a compact design representation to benefit the computational design process by employing a small number of design variables to control a broad range of complex geometries. The results also show that the design spaces based on the proposed parametrization can be successfully explored using a direct search-based method.
  • Algorithmic design of origami mechanisms and tessellations
    Item type: Journal Article
    Walker, Andreas; Stankovic, Tino (2022)
    Communications Materials
    Origami, the ancient art of paper folding, embodies techniques for transforming a flat sheet of paper into shapes of arbitrary complexity. Although this makes origami a conceptually attractive source of inspiration when designing foldable structures and reconfigurable metamaterials for multiple functionalities, their designs are still based on a set of well-studied patterns leaving the full potential of origami inaccessible for design practitioners and researchers. Here, we present a generalized approach for the algorithmic design of rigidly-foldable origami structures exhibiting a single kinematic degree of freedom. We build on generalized conditions for rigid foldability of degree-n vertices to design origami patterns of arbitrary size and complexity. The versatility of the approach is demonstrated by its capability to not only generate, analyze and optimize regular origami patterns, but also generate and analyze kirigami, generic three-dimensional panel-hinge assemblages and their tessellations. Due to its versatility, the approach provides an inexhaustible source of foldable patterns to inspire the design of metamaterials for a wide range of applications.

  • Inverse Design of Origami for Trajectory Following Using Deep Learning
    Item type: Journal Article
    Hochuli, Nicolas; Stankovic, Tino (2025)
    Journal of Mechanisms and Robotics
    This work presents a variational autoencoder (VAE)-based approach for the inverse design of rigidly foldable and single degree of freedom origami mechanisms for trajectory following. The work first develops an automated graph grammar procedure based on the principle of three units (PTU) to generate a large dataset comprising 8 million crease patterns. The distribution of origami crease patterns in the dataset is projected onto a continuous latent space using the VAE from which new designs can be sampled. The aggregated posterior distribution is approximated using normalizing flows to receive a Gaussian latent space and improve the reconstruction accuracy of crease patterns. By utilizing the continuous lower-dimensional representation of crease patterns in the latent space, the work proposes an inverse design method to design origami for trajectory following. Results demonstrate the capability of the approach to efficiently generate large datasets of rigidly foldable patterns, which in principle, can be used beyond the scope of this work. The results also show that the learned lower-dimensional representation of crease patterns enables efficient optimization of crease patterns using a series of target trajectories of varying complexity.

    Stankovic, Tino; Mueller, Jochen; Egan, Paul; et al. (2015)

    Recent progress in additive manufacturing allows for printing customized products with multiple materials and complex geometries. Effectively designing such complex products for optimal performance within the confines of additive manufacturing constraints is challenging, due to the large number of variables in the search space and uncertainties about how the manufacturing processes affect fabricated materials and structures. In this study, characteristics of materials, i.e. Young’s modulus (E), ultimate tensile strength (UTS) and density (ρ), for a multi-material inkjet-based 3D-printer are measured experimentally in order to generate data curves for a computational optimization process in configuring multimaterial lattice structures. An optimality criteria method is developed for computationally searching for optimal solutions of a multi-material lattice with fixed topology and truss cross-section sizes using the empirically obtained material measurements. Results demonstrate the feasibility of the approach for optimizing multi-material, lightweight truss structures subject to displacement constraints.
  • Rigid and Flat Foldability of a Degree-Four Vertex in Origami
    Item type: Journal Article
    Zimmermann, Luca; Stankovic, Tino (2020)
    Journal of Mechanisms and Robotics
    Rigid foldability is the property of an origami that folds continuously from an unfolded to a folded state without deformation in its facets. Although extensively researched, there exist no intrinsic conditions for the rigid foldability of a degree-four vertex, which is the simplest possible origami building block that folds nontrivially. In this paper, we derive a necessary and sufficient condition for the rigid foldability of a degree-four vertex and show that it can be reduced to a purely sufficient condition, which is equivalent to a known condition from the realm of spherical mechanisms. The implications of these conditions are discussed, which reveals the connection between rigid and flat foldability, the two most important mathematical notions in origami. In practice, this work further contributes to the design synthesis and analysis of deployable structures, in which the mechanics of degree-four vertices is omnipresent.
