Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual alignment of numerous vertices is performed, then alignment accuracy can be achieved, but the process becomes difficult and time-consuming
Solution Approach 1:
The patent introduces a spring model as an intermediary physical system to mediate the alignment process. Virtual springs connect corresponding vertices between the polygon model and texture model, automatically transmitting positional information and forces during physical simulation, thereby eliminating the need for manual vertex-by-vertex alignment while maintaining accuracy
Solution Approach 2:
The patent replaces the manual mechanical adjustment process with a computer-based physical simulation system. The spring model and physics engine automatically calculate vertex positions through simulated physical forces, substituting the time-consuming manual dragging and positioning operations with automated computational mechanics
2Manufacturing precision
If numerous vertices are aligned manually, then complete coverage can be achieved, but the operation becomes complex and difficult
Solution Approach 1:
The spring model enables the system to align itself automatically through physical simulation. When corresponding vertices are connected by virtual springs, the system self-adjusts all vertex positions through simulated physical forces without requiring manual intervention for each vertex, achieving complete alignment coverage while simplifying operation to just establishing the spring connections
Solution Approach 2:
The patent merges the alignment of all vertices into a single unified physical simulation process. Instead of treating each vertex alignment as a separate operation, the spring model combines all vertex adjustments into one automated simulation that simultaneously resolves positions for all vertices based on their interconnected spring forces
