Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If traditional coupling methods are used to secure the liquid crystal panel and backlight unit, then the coupling strength is sufficient, but the device thickness increases and slim structure cannot be achieved
Solution Approach 1:
The adhesive layer integrates multiple functions into a single component: it provides both coupling strength between the liquid crystal panel and backlight unit, and light diffusion properties. This merging eliminates the need for separate optical sheets, thereby reducing overall device thickness while maintaining structural integrity and optical performance
Solution Approach 2:
The adhesive layer serves multiple purposes simultaneously: structural coupling, light diffusion, and potential protection functions. This multi-functionality reduces the number of separate components needed, enabling a slimmer device structure without compromising the required mechanical strength or optical quality
2Length of moving object
If multiple separate components (adhesive layer and optical sheets) are used, then the optical performance is maintained, but the device size increases and slim structure cannot be achieved
Solution Approach 1:
The adhesive layer is designed to combine adhesive properties with light diffusion properties in a single integrated component. This eliminates the need for separate optical sheets while maintaining the necessary optical performance for display quality, thereby reducing device thickness
3Length of moving object
If resin frame is used to reduce device size, then the slim structure is achieved, but the protection against external impact may be insufficient
Solution Approach 1:
The frame is constructed from resin material that provides both the necessary mechanical strength for impact protection and the flexibility to achieve slim dimensions. The resin material's inherent properties allow the frame to be both thin and protective, resolving the contradiction between device slimness and impact resistance
4Reliability
If multiple separate components and complex assembly steps are used, then the coupling reliability is ensured, but the manufacturing cost increases and manufacturing complexity increases
Solution Approach 1:
The adhesive layer combines coupling and optical functions in one component, reducing the total number of parts that need to be assembled. This simplification of the component list directly reduces manufacturing complexity and assembly steps while maintaining reliable coupling between components
Solution Approach 2:
The multi-functional adhesive layer eliminates the need for separate optical sheets and simplifies the bill of materials. This reduction in component variety and数量 simplifies the manufacturing process, reduces assembly complexity, and lowers overall manufacturing costs while ensuring reliable coupling
