- Detailed Technology Description
- UCLA researchers have developed a novel computational tool, called the Boundary Learning Optimization Tool (BLOT), that identifies physical performance boundaries (e.g. structural, thermal, electrical etc.) in a system governed by multiple constraints. The fully automated tool enables the geometric optimization of FACT-synthesized topologies. The AI-assisted data acquisition process leads to rapid and automated exploration of the full design space with minimal computational efforts. BLOT can be used with existing computer-assisted design and engineering software to improve the design experience for designers and engineers. BLOT can also be used to generate Ashby-like material plots for comparing properties of natural and engineered materials. These plots will help identify trends among engineered materials that result from microstructure rather than composition.

Background
Analytical tools are necessary to rapidly optimize the performance of flexible materials that deform, yield, and/or buckle over large ranges of motion. The freedom and constraint topologies (FACT) synthesis approach helps designers rapidly consider and compare flexure systems that move in prescribed directions called degrees of freedom (DOFs) via elastic deformation. For synthesizing topologies that stiffly constrain the system’s bodies to not move in certain directions while permitting them to move in other directions with high compliance (i.e., the DOFs), FACT helps designers determine the best number and kind of flexible elements (e.g., wire or blade elements). However, FACT does not consider the material properties and geometric parameters (e.g., the lengths, widths, or thicknesses of the flexible elements or the shape and size of the rigid bodies that the flexible elements join together within the system). Therefore, there is a need for a complementary tool that can optimize the geometric parameters of the topology solutions so that final designs can better meet performance requirements.
