Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a curved display module is used to reduce external light interference and improve contrast, then the display quality is improved, but the manufacturing difficulty and assembly complexity increase
Solution Approach 1:
The patent divides the curved display assembly into separate modules: a curved back plate with first curvature and a display module with second curvature. This segmentation allows each component to be manufactured independently with optimized processes, reducing overall manufacturing complexity while maintaining the curved display quality benefit
Solution Approach 2:
A fixing member is introduced as an intermediary component between the curved back plate and the display module. This fixing member simplifies the assembly process by providing a dedicated interface that accommodates the curvature differences, thereby reducing assembly complexity while maintaining the curved display configuration
2Reliability
If a curved display module is used to reduce external light interference and improve contrast, then the display quality is improved, but the assembly time increases
Solution Approach 1:
The curved back plate and display module are designed with predetermined curvatures that match each other's curvature radii. This preliminary design decision simplifies the assembly process by eliminating the need for complex real-time adjustment, thereby reducing assembly time while maintaining display quality
Solution Approach 2:
The fixing member serves as a mediator that pre-establishes the geometric relationship between the curved back plate and display module. This intermediary component simplifies assembly by providing a ready-made interface that accommodates curvature matching, reducing assembly time without compromising display quality
3Reliability
If the display module curvature is adjusted to match the back plate curvature, then the assembly reliability is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The patent applies different curvature characteristics to different parts of the assembly: the curved back plate has a first curvature while the display module has a second curvature. This local differentiation allows each component to be manufactured with optimized precision requirements for its specific function, improving assembly reliability without uniformly increasing manufacturing precision across the entire system
Solution Approach 2:
The fixing member acts as an intermediary that absorbs and accommodates curvature differences between the back plate and display module. This mediator component simplifies the curvature matching process by providing a transition interface, thereby improving assembly reliability while reducing the stringency of curvature matching precision requirements
