Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large-screen ultra-thin display devices face challenges in ensuring structural rigidity, stability, and flatness, particularly in maintaining structural integrity and aesthetics while supporting the display panel effectively.
Innovation Solution
A display device design incorporating a material complexed plate with a core containing fibers, sandwiched between the display panel and a side frame, where the material complexed plate consists of a front skin, a rear skin, and a core, enhancing rigidity and flatness through a roll-to-roll process and hot melt adhesive coupling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the display device is made ultra-thin, then the brightness and viewing angle are improved, but the structural rigidity and stability deteriorate
Solution Approach 1:
The patent applies composite materials by constructing the rear structure with multiple layers including a rear frame, support ribs, and reinforcing plates made of different materials with complementary properties. This composite structure provides both the thinness required for modern displays and the structural rigidity needed to support the display panel, resolving the contradiction between reduced thickness and maintained strength.
2Shape
If the display device is made ultra-thin, then the brightness and viewing angle are improved, but the structural stability deteriorates
Solution Approach 1:
The patent segments the rear structure into multiple functional components including a rear frame, support ribs, and reinforcing plates positioned at specific locations. This segmentation allows each component to perform its specific function - the frame provides overall support, ribs prevent deformation, and plates reinforce critical areas - thereby maintaining structural stability while keeping the overall device thin.
Solution Approach 2:
The patent uses composite construction with multiple materials having different mechanical properties arranged in specific configurations. This composite approach enables the thin structure to achieve the necessary stability by combining materials that provide both flexibility and rigidity where needed.
3Device complexity
If the frame structure is simplified, then the manufacturing cost is reduced, but the flatness of the frame deteriorates
Solution Approach 1:
The patent applies local quality by providing reinforcing plates and support ribs only at specific locations where structural support is needed, rather than uniformly throughout the entire frame. This localized reinforcement maintains frame flatness and structural integrity while minimizing the overall complexity and material usage, thus resolving the contradiction between simplicity and flatness.
