Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a super clean foam (SCF) module with multi-layer film structure is used to support the display panel, then the display panel can be properly supported and heat dissipated, but the structure becomes complex and manufacturing becomes cumbersome
Solution Approach 1:
The patent merges multiple functions (support, adhesion, heat dissipation) into a single integrated back plate component. This back plate replaces the complex multi-layer SCF module while maintaining the necessary support and thermal management functions, thereby simplifying the overall structure.
Solution Approach 2:
The back plate is designed as a multi-functional component that simultaneously provides structural support, adhesion to the display panel, and heat dissipation capabilities. This universal component eliminates the need for separate specialized layers while achieving all required functions.
2Reliability
If a super clean foam (SCF) module with multi-layer film structure is used, then the display panel can be supported, but the manufacturing process becomes complex and production cost increases
Solution Approach 1:
The patent combines multiple manufacturing steps and components into a single back plate that can be produced and attached in fewer steps. This integration reduces the complexity of the manufacturing process while maintaining the required support function.
Solution Approach 2:
The invention extracts and eliminates the complex multi-layer SCF module from the manufacturing process, replacing it with a simpler back plate structure that achieves the same functional outcome with reduced manufacturing complexity.
3Reliability
If a super clean foam (SCF) module with multi-layer film structure is used, then the display panel can be supported, but the thickness of the display module increases
Solution Approach 1:
The patent consolidates multiple thick film layers into a single thinner back plate that provides equivalent or superior support functionality. This merging reduces the overall thickness of the display module while maintaining structural integrity.
Solution Approach 2:
The back plate is designed as a thin, flexible yet strong component that provides adequate support with minimal thickness, replacing the bulkier multi-layer SCF module and reducing the overall module thickness.
