Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional connection methods are used for light emitting elements to display substrate, then device complexity is reduced, but connection reliability deteriorates
Solution Approach 1:
The patent combines multiple functions into the molding structure: it serves as both the protective encapsulation for light emitting elements and the connection interface to the display substrate. The molding integrates electrode extensions and connection portions that directly bond to the substrate, eliminating the need for separate connection components and achieving both reliability and simplicity.
Solution Approach 2:
The molding structure performs multiple functions simultaneously: it protects light emitting elements, provides electrical connections through integrated electrodes, enables mechanical bonding to the substrate, and facilitates heat dissipation. This multi-functionality resolves the contradiction by achieving reliable connections without adding device complexity.
2Manufacturing precision
If light emitting elements are firmly connected to display substrate, then display quality improves, but manufacturing complexity increases
Solution Approach 1:
The molding structure is pre-formed with integrated electrodes and connection portions before assembly. This preliminary preparation ensures precise alignment and firm connection when the module is assembled to the display substrate, achieving high display quality while simplifying the final manufacturing process.
3Reliability
If electrodes extend in multiple directions for better connection, then connection reliability improves, but device complexity increases
Solution Approach 1:
The patent merges multiple electrode extensions into a single integrated molding structure. The electrodes extend in multiple directions within the molding to achieve reliable electrical connections, but this complexity is contained within the molding itself rather than requiring separate electrode components, thus maintaining overall device simplicity.
