Engineering Contradiction Analysis
1Ease of operation
If conventional geometry-based design models are used, then design precision and continuity are maintained, but modification difficulty and processing time increase significantly
Solution Approach 1:
The patent segments continuous geometry into discrete voxel units organized in a grid structure. Each voxel represents a simplified geometric primitive that can be independently modified, eliminating the complexity of editing continuous surfaces while maintaining overall design fidelity through aggregation of voxel elements.
2Productivity
If continuous geometry-based models are used, then design accuracy is preserved, but real-time rendering and optimization become infeasible
Solution Approach 1:
The patent creates a voxel-based copy or representation of the continuous geometry. This voxel model serves as a computationally efficient surrogate that approximates the original continuous form, enabling real-time rendering and optimization operations while the final design can be exported back to precise geometry formats.
3Adaptability or versatility
If conventional optimization techniques are applied to continuous geometry, then comprehensive optimization is achieved, but computational resources and time requirements become prohibitive
Solution Approach 1:
The patent transforms the geometric representation from continuous parameters to discrete voxel parameters. This parameter discretization reduces the dimensionality and complexity of the optimization space, allowing standard optimization algorithms to operate efficiently while still providing meaningful design exploration and optimization capabilities.
4Ease of operation

Solution Approach 1:
The patent enables users to directly modify design models through intuitive voxel manipulation without requiring specialized knowledge of geometric modeling tools. The system provides self-service capabilities where users can add, remove, and configure voxels through simple operations, with the underlying system automatically handling the complex geometry generation and validation.
