Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple external coupling wires are used to connect terminals on array and counter substrates in each light adjustment panel, then electrical connection is achieved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent merges the electrical connection function across multiple light adjustment panels by introducing a conductive member that spans multiple panels. Instead of using separate external coupling wires for each panel, the conductive member integrates the connection function across panels, reducing the total number of wires needed while maintaining reliable electrical connection between terminals on array and counter substrates.
Solution Approach 2:
The conductive member serves multiple functions simultaneously: it acts as an electrical connector between terminals on different substrates, provides structural support for the stacked panel configuration, and reduces the overall number of external coupling wires required. This multi-functional approach resolves the contradiction by achieving reliable electrical connection with reduced device complexity.
2Reliability
If multiple external coupling wires are used for each light adjustment panel, then electrical connection is ensured, but manufacturing efficiency decreases
Solution Approach 1:
The patent combines multiple electrical connection operations into a single integrated structure. The conductive member that spans multiple light adjustment panels allows manufacturers to establish electrical connections across panels in fewer discrete steps, reducing assembly complexity and improving manufacturing efficiency while ensuring reliable electrical connection.
Solution Approach 2:
The conductive member is pre-configured to span multiple panels during the manufacturing process, allowing electrical connections to be established before final assembly. This preliminary action reduces the need for subsequent complex wiring operations and improves overall manufacturing efficiency while maintaining connection reliability.
3Reliability
If multiple external coupling wires are used in each light adjustment panel, then electrical connection is achieved, but bezel width increases
Solution Approach 1:
The patent merges the electrical connection pathways into a more compact configuration. By using a conductive member that spans multiple panels rather than separate wires for each panel, the overall footprint and bezel width are reduced, while still achieving reliable electrical connection between the terminals on array and counter substrates.
