Adhesive Tape Segmentation for Display Panel Shock Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Signage-use liquid crystal display panels face challenges in maintaining sufficient durability against external forces such as falling or shaking, as traditional holder structures are inadequate in providing sufficient support and protection.
Innovation Solution
A display device design featuring a support plate with strategically placed adhesive tapes that attach to the display panel, providing reinforcement and shock absorption, while allowing for easy removal and maintenance by creating cuttable gaps in the adhesive regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional holder structure is used to hold the periphery portion of the display panel, then the device is simple in structure, but the durability against external forces such as falling or shaking is insufficient
Solution Approach 1:
The adhesive tape is divided into multiple regions with different adhesive properties: a first adhesive region with strong adhesion for securing the panel, and a second adhesive region with weak adhesion for easy removal. This segmentation allows the single component to provide both strong durability and easy maintainability, resolving the contradiction between reliability and ease of operation.
Solution Approach 2:
Different portions of the adhesive tape have different adhesive strengths tailored to specific functional requirements. The first adhesive region (peripheral portion) provides strong bonding for structural durability, while the second adhesive region (central portion) provides weak bonding for easy removal during maintenance. This local differentiation of adhesive quality enables the system to simultaneously achieve high reliability and ease of operation.
2Reliability
