Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video wall technologies face challenges in securely and reliably fastening optical elements with limited space requirements, and in effectively managing light interference from external sources such as sunlight, which affects the color quality and stability of the display.
Innovation Solution
The proposed solution involves a module design with retaining pins and recesses that allow for secure mechanical fastening of optical elements between components, using a combination of interlocking and adhesive bonding, and incorporates shading elements and radiation-guiding components to improve light management and stability, even in tight spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If optical elements are mounted on the surface of components, then the mounting process is simple, but the mechanical fixing stability is insufficient
Solution Approach 1:
The patent combines surface mounting with mechanical fastening by integrating retaining pins that extend into retaining recesses formed between adjacent components. This merging of mounting approaches provides both the simplicity of surface mounting and the stability of mechanical fixing, resolving the contradiction between ease of manufacture and mechanical fixing stability.
2Strength
If adhesive bonding is used to fasten optical elements, then strong bonding is achieved, but repair and replacement become difficult
Solution Approach 1:
The patent employs a dynamic fastening system using retaining pins that can be inserted and removed from retaining recesses. This mechanical fastening method allows optical elements to be easily installed, replaced, or repaired without permanent bonding, resolving the contradiction between bonding strength and repairability by providing reversible yet secure fastening.
3Device complexity
If retaining recesses are formed only in individual components, then the fastening structure is simple, but the retaining recess diameter is limited
Solution Approach 1:
The patent merges the retaining recess structures of multiple adjacent components to form a larger combined retaining recess. By forming recesses in neighboring components that align with each other, the system achieves a larger effective retaining recess diameter while maintaining the simplicity of individual component design, thus resolving the contradiction between device complexity and retaining recess diameter.
4Object-affected harmful factors
If shading elements are added to protect against sunlight, then color quality improves, but device complexity increases
Solution Approach 1:
The patent integrates shading elements into the existing component structure, where the same structural components serve both mechanical support and light shielding functions. This multi-functionality approach provides protection against light interference while minimizing additional structural complexity, resolving the contradiction between harmful factor protection and device complexity.
