Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a conventional frame structure with multiple components and adhesives is used, then the display apparatus can maintain mechanical stability, but the structure becomes complex and the thickness increases
Solution Approach 1:
The patent merges the frame structure into a single integrated component that simultaneously provides mechanical support, positioning, and light shielding functions. The frame structure includes integrated light shielding parts at corners and ribs along edges, eliminating the need for separate adhesive layers and multiple components, thus reducing structural complexity while maintaining mechanical stability
Solution Approach 2:
The frame structure is designed to perform multiple functions simultaneously: it provides mechanical support, positions the display panel and backlight unit, prevents deformation, and blocks light leakage. This multi-functionality reduces the number of components needed and simplifies the overall structure while maintaining stability
2Ease of operation
If adhesives are used to hold the display panel and substrate, then mechanical stability is maintained, but the structure becomes complex and assembly becomes difficult
Solution Approach 1:
The patent extracts and eliminates the adhesive layer from the structure by designing a frame structure with integrated light shielding parts and positioning ribs that mechanically hold the display panel and backlight unit in place, simplifying assembly while maintaining stability
Solution Approach 2:
The frame structure is designed to self-position and self-hold the display panel and substrate through its integrated light shielding parts and positioning ribs, eliminating the need for adhesives and complex assembly procedures while maintaining mechanical stability
3Length of stationary object
If the frame structure is simplified to reduce thickness, then the apparatus becomes thinner, but mechanical strength and deformation prevention may be compromised
Solution Approach 1:
The patent extends light shielding parts and positioning ribs from the frame structure into the space between the display panel and backlight unit, utilizing the thickness dimension to provide mechanical support and light blocking without increasing the overall footprint, thus reducing thickness while maintaining strength
Solution Approach 2:
The frame structure is designed as an integrated composite structure combining rigid light shielding parts at corners with flexible positioning ribs along edges, creating a unified component that provides both mechanical strength and deformation prevention while minimizing thickness
