Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the display device is made ultra-thin, then the profile is reduced and viewing angle characteristics are improved, but structural rigidity and stability deteriorate
Solution Approach 1:
The patent employs a composite structure consisting of a front skin, rear skin, and core material. The core includes fibers embedded in a resin matrix, creating a composite material that provides both rigidity and stability while maintaining ultra-thin profile. This composite construction resolves the contradiction by delivering structural strength without increasing thickness.
Solution Approach 2:
The display device structure is segmented into multiple functional layers: front skin, rear skin, and core. The core itself is segmented into fibers distributed within a resin matrix. This segmentation allows each layer to perform its specific function while collectively providing the necessary structural rigidity without compromising the ultra-thin profile.
2Length of moving object
If the display device is made ultra-thin, then the profile is reduced, but structural stability deteriorates
Solution Approach 1:
The composite structure with fibers embedded in resin provides structural stability while maintaining ultra-thin thickness. The fiber-resin composite combination ensures consistent dimensional stability and resistance to deformation, resolving the contradiction between thin profile and structural stability.
Solution Approach 2:
The core material is designed with specific local properties - fibers are strategically positioned within the resin matrix to provide stability where needed. The front and rear skins are positioned to maintain structural integrity at critical locations, ensuring overall stability without increasing overall thickness.
3Device complexity
If a simple coupling structure is used, then device complexity is reduced, but durability and stability of coupling deteriorate
Solution Approach 1:
The coupling member is designed with a nested structure where an inner solid is inserted into an outer shell. Both components are inserted through the coupling hole in the material complexed plate, creating a nested arrangement that provides durable and stable coupling while maintaining reasonable structural complexity.
Solution Approach 2:
The coupling member utilizes composite construction with outer shell and inner solid components that work together to provide durable coupling. This composite approach to the coupling structure ensures reliability while managing complexity through functional integration.
