Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in reducing thickness and width while maintaining impact-absorption and waterproof functions, leading to potential damage from external impacts and moisture penetration.
Innovation Solution
Incorporating a display panel with a support member and a cushion plate featuring a porous substrate, where the corresponding side surfaces of the display panel, support member, and cushion plate are aligned or coincident, and applying a resin to the side surfaces to enhance rigidity and prevent moisture permeation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If the thickness of the display device is reduced, then the portability and design are improved, but the impact-absorption function is reduced
Solution Approach 1:
The patent employs a porous cushion plate positioned between the display panel and the case. The porous structure provides effective impact absorption while maintaining a thin profile, as the void spaces within the material allow for energy dissipation without requiring significant thickness.
Solution Approach 2:
The cushion plate is constructed as a composite structure combining a base material with a porous layer. This composite design integrates both structural support and impact absorption functions within a single thin component, resolving the contradiction between reduced thickness and maintained reliability.
2Length of stationary object
If the thickness of the display device is reduced, then the portability and design are improved, but the waterproof function is reduced
Solution Approach 1:
The patent utilizes a thin waterproof film or coating applied to the cushion plate and surrounding structures. This thin film provides effective moisture barrier protection while maintaining the reduced thickness design, preventing water penetration without requiring thick protective layers.
Solution Approach 2:
The waterproofing strategy employs composite construction where the cushion plate is combined with waterproof films and sealing materials. This multi-material approach achieves both thinness and effective waterproofing by integrating protection functions into the structural components.
3Reliability
If additional components are added to improve impact-absorption and waterproof functions, then the reliability is improved, but the thickness and width increase
Solution Approach 1:
The patent merges multiple functions into the cushion plate component. The cushion plate simultaneously serves as a structural support element, an impact-absorbing component, and a platform for waterproof sealing. This consolidation eliminates the need for separate components, maintaining thin dimensions while achieving reliable protection.
Solution Approach 2:
The cushion plate is designed as a multi-functional component that performs both impact absorption and waterproof sealing. By making this single component universal, the design avoids adding extra thickness or width that would result from using separate specialized components for each function.
