Foldable Display Mounting Member Slim Bezel Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable display devices face challenges in minimizing the bezel area and simplifying the coupling process between the flexible display panel and the housing, often resulting in increased bezel size due to protruding coupling portions.
Innovation Solution
A foldable display device design that eliminates protruding coupling portions by using a mounting member between the lower plate and the housing, allowing for a slim bezel and simplified assembly, with a mounting member that securely couples the lower plate to the housing using a metal material with a hole pattern for stability and heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If coupling portions protrude from both ends of the lower plate to connect the display panel to the housing, then the structural integrity and connection strength are improved, but the bezel area increases
Solution Approach 1:
The patent extracts the coupling function from the lower plate itself by introducing a separate mounting member. The mounting member includes coupling portions that protrude and engage with the housing, while the lower plate maintains a clean, non-protruding appearance. This separation allows the coupling function to be fulfilled without increasing the bezel area of the lower plate.
Solution Approach 2:
The mounting member acts as an intermediary component between the lower plate and the housing. It provides the necessary coupling portions for strong connection to the housing while allowing the lower plate to maintain its compact design without protruding elements, thus resolving the conflict between connection strength and bezel area.
2Reliability
If coupling portions protrude from the lower plate to ensure secure connection, then the reliability of the connection is improved, but the device complexity increases
Solution Approach 1:
The complex coupling structure is extracted from the lower plate and consolidated into a separate mounting member. This mounting member integrates all coupling portions and connection features in one component, simplifying the overall assembly process and reducing the complexity of the lower plate while maintaining reliable connections.
Solution Approach 2:
The mounting member merges multiple functions into a single component: it provides coupling portions for housing attachment, supports the lower plate, and ensures proper positioning. This consolidation reduces the number of separate parts and simplifies the coupling structure while maintaining connection reliability.
3Area of stationary object
If a mounting member is introduced between the lower plate and housing to eliminate protruding coupling portions, then the bezel area is reduced, but the device complexity increases
Solution Approach 1:
The mounting member is designed as a universal component that performs multiple functions: it provides coupling portions for housing attachment, supports the lower plate, ensures proper positioning, and eliminates the need for protruding coupling portions on the lower plate. This multi-functionality justifies the additional component by consolidating several functions into one element.
Solution Approach 2:
The mounting member is positioned in a different dimensional space between the lower plate and housing, allowing it to provide coupling functionality without occupying the lateral space that would increase bezel area. The coupling portions extend in a direction that does not increase the horizontal footprint of the lower plate.
