1Extent of automation
If manual design creation and iterative testing are used in existing CAD tools, then design control and precision are maintained, but design automation and optimization capability are limited
Solution Approach 1:
The system enables self-service by allowing the mechanical part to automatically generate its own optimized geometry through simulated growth processes. The part iteratively adapts its structure in response to applied loads and constraints without requiring manual intervention, effectively designing itself based on functional requirements.
Solution Approach 2:
The design process transitions from static manual modeling to dynamic automated evolution. The mechanical part's geometry dynamically changes through iterative simulation cycles where the structure grows and adapts in real-time response to testing stimuli, enabling continuous optimization.
2Manufacturing precision
If traditional CAD tools require users to create geometry explicitly, then design intent is clearly defined, but automatic optimization based on simulation results is prevented
Solution Approach 1:
The system performs preliminary actions by pre-defining the design space boundaries, material properties, and loading conditions before the actual design process begins. This allows the automated growth algorithm to operate within constrained parameters, ensuring design precision while maintaining efficiency.
Solution Approach 2:
The system implements continuous feedback loops where simulation results from stress analysis and performance testing automatically feed back into the design process. The mechanical part uses this feedback to iteratively adjust its geometry, removing material from low-stress areas and reinforcing high-stress regions, thereby achieving automatic optimization.
3Reliability
If iterative testing and manual modification are performed, then design validation is thorough, but time consumption increases significantly
Solution Approach 1:
The system maintains continuity of useful action by eliminating idle time between design and testing phases. The automated growth process continuously evolves the mechanical part geometry based on real-time simulation feedback, ensuring that every iteration builds upon previous results without manual intervention delays.
Solution Approach 2:
The system replaces the mechanical process of manual design modification with an automated computational algorithm. The growth-based design algorithm automatically interprets simulation results and modifies geometry accordingly, substituting human manual operations with automated mechanical-computational processes that are both thorough and time-efficient.

AI summary
Systems and methods are disclosed for generating designs for mechanical parts in a computer aided design (CAD) context. One method includes generating a model of a mechanical part, the model including one or more cells, wherein each cell is comprised of a plurality of parameterized representations, each of the plurality of parameterized representations representing a material property; determining, for each cell, a cell-specific parameter value for each of the parameterized representations; comparing, for each cell, each of the cell-specific parameter values to a corresponding threshold parameter value associated with each of the representations of the material properties; and generating at least one additional cell or removing at least one of the one or more cells based on the comparison of each cell-specific parameter value to the corresponding threshold parameter value.
