Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple masks are used in the conventional manufacturing process, then the touch-controlled panel can be manufactured with proper electrode patterns and bridging connections, but the production cost increases and the manufacturing process becomes complex
Solution Approach 1:
The patent combines the formation of the organic film and the bridging connection layer into a single masking step. The mask simultaneously defines both the organic film regions and the bridging connection layer regions, reducing the number of masks from multiple to one, thereby simplifying the manufacturing process while maintaining pattern accuracy
Solution Approach 2:
The single mask serves multiple functions: it defines the organic film deposition areas, defines the bridging connection layer formation areas, and ensures proper alignment between electrodes and connections. This multi-functional mask reduces process complexity while maintaining manufacturing precision
2Manufacturing precision
If multiple masks are used in the conventional manufacturing process, then the touch-controlled panel can be manufactured with proper electrode patterns and bridging connections, but the production cost increases
Solution Approach 1:
The patent merges the masking steps for organic film formation and bridging connection layer formation into a single step. This reduces the number of masks required from multiple to one, directly reducing material costs and process costs while maintaining the necessary pattern accuracy for electrode and connection formation
3Reliability
If the first electrodes and the second electrodes are arranged in the same layer and connected through a bridging connection layer, then the touch-controlled function is achieved, but the manufacturing process requires more masks and becomes complex
Solution Approach 1:
The patent combines the definition of organic film regions and bridging connection layer regions into a single mask design. This allows the bridging connection layer to be formed in the same masking step as the organic film, reducing process complexity while ensuring reliable electrical connections between electrodes for touch control functionality
