Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional conductive bridges are used with larger size and non-uniform arrangement, then electrical connectivity is ensured, but visibility and aesthetic appeal deteriorate
Solution Approach 1:
The patent applies parameter changes by reducing the size of conductive bridges and changing their arrangement pattern from non-uniform to symmetrical. Specifically, the conductive bridges are designed with minimized dimensions and arranged in a symmetrical pattern around the central electrode, which reduces their visual prominence while maintaining electrical connectivity functionality.
Solution Approach 2:
The patent employs asymmetry in reverse by introducing symmetry into the conductive bridge arrangement. The conductive bridges are positioned symmetrically with respect to the central electrode, creating a balanced and uniform appearance that reduces visual disruption compared to conventional non-uniform arrangements.
2Reliability
If conductive bridges are made more prominent to ensure connectivity, then electrical performance is improved, but aesthetic appeal and visibility are worsened
Solution Approach 1:
The patent changes the parameters of conductive bridges by minimizing their size and optimizing their arrangement. The bridges are designed with reduced dimensions and positioned in a symmetrical pattern that maintains electrical reliability while minimizing visual disruption to the display surface.
Solution Approach 2:
The patent applies local quality by optimizing the specific arrangement and dimensions of conductive bridges in different regions. The symmetrical arrangement ensures that conductive bridges are distributed uniformly around the central electrode, creating consistent visual quality across the display surface while maintaining local electrical connectivity.
3Shape
If symmetrical arrangement of conductive bridges is implemented, then aesthetic appeal is improved, but manufacturing complexity increases
Solution Approach 1:
The patent employs symmetry in the arrangement of conductive bridges around the central electrode. This symmetrical configuration creates a uniform and aesthetically pleasing appearance, with conductive bridges positioned at equal intervals and orientations relative to the center, simplifying the visual pattern while maintaining manufacturing feasibility.
