Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a touch function is integrated into display panels, then the functionality and user interaction capability are improved, but the manufacturing complexity and cost increase
Solution Approach 1:
The patent moves the conductive member from the traditional planar layout on the display surface to a three-dimensional configuration along the side surface of the substrate. This dimensional transition allows the touch signal transmission path to be established without adding complex lateral wiring structures, thereby reducing manufacturing complexity while enabling touch functionality.
Solution Approach 2:
The conductive member disposed on the side surface acts as an intermediary element that bridges the touch layer and the external circuit. This intermediate structure simplifies the overall system architecture by providing a dedicated signal transmission path that does not interfere with the display layer structure, thus reducing manufacturing complexity.
2Adaptability or versatility
If traditional touch signal transmission methods are used, then touch functionality is achieved, but the material costs and structural complexity increase
Solution Approach 1:
The patent extracts the conductive member from the traditional planar configuration and positions it separately on the side surface of the substrate. This extraction allows for optimized material usage, as the conductive member can be implemented with simpler materials and structures compared to complex planar wiring, thereby reducing material costs.
Solution Approach 2:
The side surface conductive member serves multiple functions: it provides electrical connection for touch signals, acts as a structural element, and does not interfere with the display function. This multi-functionality reduces the need for additional separate components, thereby reducing overall material costs.
