GENERATING CONSOLIDATED DESIGNS OF A PRODUCTION MODEL TO REPLACE MULTIPLE PARTS OF AN ASSEMBLY
Techniques, devices, and systems for automatically generating consolidated designs of a production model to replace multiple parts of an assembly are disclosed herein. For example, a set of digital models may be originally designed to be separately manufactured and assembled post production. The present disclosure analyzes the set of digital models and computes candidates of consolidated designs that consolidates a subset number of the digital models into a single part to be manufactured. The computation may be based on certain complexity level (e.g., based on manufacturing capability and/or user preference/input). The consolidated designs simplify the manufacturing process by reducing individual parts to be manufactured and the subsequent assembly, as well as improving reliability, improving automation, and reducing manufacturing costs.
