Light Guide Plate Elastic Protrusion Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light guide plate fixation methods either result in unstable structures prone to shaking and light spot generation due to friction or require complex assembly and high labor and material costs with the use of buffer members.
Innovation Solution
A light guide plate design featuring protruding portions and slots for elastic deformation, combined with guiding mechanisms on the external lateral surfaces, allows for stable positioning and fixation through interference fit with a backboard or frame, simplifying assembly and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the light guide plate is clamped to a backboard through clamping members, then assembly is simple, but the structure has low stability and light spots may be generated due to friction
Solution Approach 1:
The patent merges the clamping function and positioning function into a single integrated structure. The clamping member includes both a clamping portion that contacts the light guide plate and a positioning portion that engages with a positioning groove on the backboard, eliminating the need for separate positioning components and achieving both simple assembly and stable fixation.
Solution Approach 2:
The patent introduces a buffer member as an intermediary between the clamping member and the light guide plate. This buffer member reduces friction and prevents direct contact that causes light spots, while still maintaining the clamping force needed for stable fixation, thus resolving the contradiction between stability and light spot generation.
2Reliability
If a buffer member is provided between the light guide plate and the backboard, then the light guide plate may not shake and the product is of high quality, but complex assembly and high labor and material costs are caused
Solution Approach 1:
The patent combines the buffer member with the clamping member into an integrated component. The buffer member is attached to the clamping member, allowing both the buffering function and the clamping function to be achieved through a single assembly operation, thereby reducing assembly complexity while maintaining structure stability.
Solution Approach 2:
The clamping member is designed to perform multiple functions: it provides clamping force through the clamping portion, positions the light guide plate through the positioning portion, and reduces friction through the integrated buffer member. This multi-functionality reduces the number of separate components needed, simplifying assembly while maintaining stability.
