The design engine generates a user interface that exposes tools for capturing input data related to the design problem. Based on the input data, the design engine performs various operations to generate a formalized problem definition that can be processed by a goal-driven optimization algorithm. The goal-driven optimization algorithm generates a spectrum of potential design options. Each design option describes a mechanical assembly representing a potential solution to the design problem. ## Claims ### Claim 1 A computer-implemented method for generating design options for mechanical assemblies, the method comprising: receiving, via a graphical user interface, one or more optimization parameters associated with an optimization algorithm;
