Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If components such as cameras and sensors are integrated inside the display area, then the functionality and versatility of the display device are improved, but the complexity of wiring arrangement increases and display quality may deteriorate
Solution Approach 1:
The patent applies asymmetry by designing signal lines with different routing patterns on opposite sides of the hole. The first signal line has a first routing pattern and the second signal line has a second routing pattern that is asymmetric to the first, allowing optimized wiring arrangement around the hole while maintaining display quality and reducing interference between adjacent signal lines
2Ease of manufacture
If signal lines are arranged symmetrically around holes, then the design process is simplified, but wiring integrity may be compromised and interference between signal lines increases
Solution Approach 1:
The patent employs asymmetric routing patterns for signal lines around holes. Specifically, the first signal line extends in a first direction with a first routing pattern, while the second signal line extends in a second direction (opposite to the first) with a second routing pattern asymmetric to the first. This asymmetric design optimizes wiring integrity and reduces electromagnetic interference between adjacent signal lines, outweighing the increased design complexity
