Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional three-dimensional sculpture software methods are used to produce artistic works, then high-quality texture sculpture can be achieved, but the production process becomes lengthy and complex
Solution Approach 1:
The patent segments the production process into distinct modular steps: obtaining initial model, generating height map, processing to multiple texture maps (Alpha, BaseColor, Roughness, Normal, AO, Metallic), and fusing maps. This segmentation allows each step to be optimized independently and enables reusable workflows that reduce overall production time while maintaining texture quality
Solution Approach 2:
The patent performs preliminary actions by pre-generating standardized texture maps (Alpha, BaseColor, Roughness) and auxiliary maps (Normal, AO, Metallic) from the height map before final assembly. These pre-processed maps can be reused across different projects, eliminating repetitive manual texture work and significantly reducing production time
2Manufacturing precision
If traditional three-dimensional sculpture software methods are used, then artistic detail can be achieved, but the process becomes inflexible and non-reusable
Solution Approach 1:
The patent creates a universal workflow that can be applied to different three-dimensional models and artistic styles. The standardized process of generating height maps and processing them into multiple texture maps serves multiple functions: it works for various model types, produces consistent results across projects, and enables the same workflow to be reused for different artistic works, thereby increasing flexibility and reusability
Solution Approach 2:
The patent utilizes parameter changes in the height map processing stage, where adjustable parameters control the generation of different texture maps. By modifying processing parameters, the same base workflow can produce varied artistic details and styles, providing both consistency and adaptability without requiring complete process redesign
3Manufacturing precision
If traditional three-dimensional sculpture software methods are used, then normal information can be baked to low-quality model, but the overall process remains complex and error-prone
Solution Approach 1:
The patent creates accurate copies of three-dimensional surface information by generating height maps from mesh models and then deriving multiple texture maps through systematic processing. This copying approach preserves normal information accuracy while automating the transfer process, reducing manual intervention and potential errors in the traditionally complex baking process
