Edge-Type LCD Wire Fixation via L-Shaped Structural Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In edge-type liquid crystal display devices, the wires connecting the lamp assembly to the power source are prone to coming off during handling or inspection, leading to potential damage and increased manufacturing costs due to the need for additional fixing methods like tapes or foams.
Innovation Solution
The implementation of L-shaped and reversed L-shaped wire fixation parts on the main support and guide panel, respectively, to securely accommodate and fix the wires, preventing movement and damage, and allowing for efficient injection molding without additional processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional fixing methods like tapes or foams are used to secure wires, then wire stability is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The wire fixation function is merged with the existing structural components (main support and guide panel) by integrating L-shaped and reversed L-shaped fixation parts directly into these parts. This eliminates the need for separate fixing methods like tapes or foams, thereby maintaining wire stability while reducing device complexity and manufacturing cost.
Solution Approach 2:
The main support and guide panel structures provide self-fixing capability through their integrated L-shaped and reversed L-shaped parts. The wires are secured by the structural design itself without requiring external fixing materials or additional processes, achieving wire stability through the structure's own geometry.
2Reliability
If additional fixing processes are implemented to prevent wire coming off, then wire reliability is improved, but manufacturing time and cost increase
Solution Approach 1:
The L-shaped and reversed L-shaped wire fixation parts are pre-formed as integral parts of the main support and guide panel structures. This preliminary integration means that wire fixation is already prepared in the structure itself, eliminating the need for additional fixing processes during assembly and maintaining high manufacturing efficiency.
Solution Approach 2:
The wire fixation function is combined with the structural components, so that a single assembly operation simultaneously achieves both structural assembly and wire fixation. This merging of functions eliminates separate fixing processes, thereby improving productivity while ensuring wire connection reliability.
3Reliability
If L-shaped and reversed L-shaped wire fixation parts are integrated into the structure, then wire stability is improved, but structural complexity increases
Solution Approach 1:
The wire fixation function is segmented into two distinct L-shaped parts: one integrated into the main support and another into the guide panel. This segmentation allows each part to perform a specific fixation function while maintaining the overall simplicity of the structure, as each L-shaped part is a straightforward geometric feature rather than a complex mechanism.
Solution Approach 2:
The use of L-shaped and reversed L-shaped fixation parts introduces asymmetric geometry that is optimized for wire retention. These asymmetric forms provide effective wire fixation through their geometric configuration alone, achieving high wire fixation reliability without requiring complex symmetric or multi-component structures.
