Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If square touch electrodes are used, then the structure is simple and easy to manufacture, but the adaptability to circular or other-shaped touch panels is poor
Solution Approach 1:
The electrode layer is segmented into multiple independent hexagonal electrodes arranged in a specific pattern, allowing the electrode structure to adapt to different panel shapes while maintaining manufacturability through standardized hexagonal units
Solution Approach 2:
The patent transitions from symmetric square electrodes to hexagonal electrodes with different geometric properties, enabling better adaptation to circular and other non-rectangular panel shapes while maintaining structural simplicity
2Ease of manufacture
If square electrodes are used for circular touch panels, then the manufacturing process remains standard, but the electrode shape does not match the panel shape reducing effectiveness
Solution Approach 1:
The electrode shape parameter is changed from square to hexagonal, which better approximates circular shapes and improves the match between electrode geometry and panel shape, thereby enhancing detection precision without significantly complicating manufacturing
3Adaptability or versatility
If more electrodes are used to improve coverage on circular panels, then the adaptability increases, but the number of processing circuits and costs increase
Solution Approach 1:
The hexagonal electrode design serves multiple functions: it adapts to various panel shapes (circular, rectangular, irregular), maintains efficient charge distribution, and reduces the total number of electrodes needed compared to square electrode designs, thereby improving adaptability without proportionally increasing complexity
