Item type:Publication, Access status: without files , Automated design of 3D-printed silicone parts : a case study on hand rehabilitation gloves for stroke patientsThis paper presents an innovative way to customize silicone products by utilizing a design automation process and extrusion-based silicone 3D printing as a manufacturing technique. A customizable rehabilitation glove for stroke patients is used as an example to demonstrate the process chain. Soft robotics offers unique possibilities for the use of rehabilitation devices in a homecare setting and has the potential to support the healing process throughout the different steps of neurorehabilitation. Furthermore, customization of such devices can make physical therapy more comfortable and effective for the patient. The presented process chain combines pose detection with parametric design in order to adapt a glove consisting of soft bending actuators to the hand of a patient, which can be manufactured in a single day.Publicationtype: Book part18 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Access status: with files , Methodology for integrating biomimetic beams in abstracted topology optimization results(American Society of Mechanical Engineers (ASME), 2022-10); ; ; ; This paper presents a five-step design methodology to generate designs of biomimetic structural components from topology optimization results. In step one, all material allocated by topology optimization is classified as either beam like structures or nodes to generate an auxiliary model consisting of preserved regions, cylindrical beams, and ball nodes, which is an abstraction of the original topology optimization result. In step two, the auxiliary model is exposed to the original boundary conditions in a finite element analysis. Then, internal forces, torsion, and bending moments in all beams of the auxiliary model are identified with respect to both of their ends. In step three, a database is used to find a suitable biomimetic beam for each previously analyzed beam in the auxiliary model. In step four, adapted nodes are designed to connect the biomimetic beams and preserved regions to generate an intermediate biomimetic component design. And in step five, a design iteration and a validation of the final design are performed. The design methodology allows for reproducible bio-mimetic component designs, a trackable and easily documentable component development process, and the possibility of automating the design process to ultimately save development costs when designing structural components.Publicationtype: Conference Paper55 177
