Engineering Contradiction Analysis
1Reliability
If separate conductive elements are used for light emission and electrical connection, then functional reliability is improved, but device complexity and fabrication difficulty increase
Solution Approach 1:
The patent combines light emission and electrical connection functions into a single conductive element. The conductive element includes a conductive layer that can emit light and semiconductor layers that provide electrical connection, merging two separate functional components into one integrated structure.
Solution Approach 2:
The conductive element is designed to perform multiple functions simultaneously: it serves as both a light-emitting component and an electrical connector. The element insulating layer and conductive pattern layer work together to enable both optical and electrical functions within a single component.
2Reliability
If multiple separate components are used for light emission and electrical connection, then functional performance is improved, but manufacturing process complexity increases
Solution Approach 1:
The patent merges multiple manufacturing steps into a more integrated process. By forming the conductive layer, element insulating layer, and conductive pattern layer in a coordinated sequence, the patent reduces the number of separate assembly steps required compared to manufacturing separate conductive elements and connecting them.
3Ease of manufacture
If a simple conductive element structure is used, then fabrication ease is improved, but functional integration of light emission and electrical connection deteriorates
Solution Approach 1:
The conductive element achieves multi-functionality through its layered structure. The conductive layer provides both light emission capability and electrical conductivity, while the element insulating layer and conductive pattern layer enable the element to serve as both an optical component and an electrical connector within a relatively simple fabrication process.
