Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If virtual axes are used to search for cross sections in three-dimensional target part images, then cross section location can be achieved, but the process becomes cumbersome and complex
Solution Approach 1:
The patent extracts and removes the virtual axis component from the cross-section search process. Instead of requiring users to work with virtual axes, the system directly identifies and displays cross-sections based on geometric relationships in the 3D target part image, eliminating the intermediary virtual axis concept that caused complexity
Solution Approach 2:
The patent inverts the traditional approach by not starting with a virtual axis and then finding cross-sections, but rather starting directly with the target cross-sections and determining their positions through geometric characteristics of the 3D image itself, reversing the logical sequence to simplify the process
2Adaptability or versatility
If geometrical characteristics of cross sections are fixed, then calculation is simplified, but flexibility in selecting suitable cross sections is reduced
Solution Approach 1:
The patent implements dynamic geometrical characteristics for cross-sections, allowing users to modify position, orientation, and shape parameters interactively. The system recalculates and redisples cross-sections in real-time based on user adjustments, providing flexibility without requiring complex manual manipulation through the virtual axis method
