Foldable Display Hinge Covers With Protrusion Gap Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices, especially foldable and bendable ones, face challenges in preventing the penetration of foreign substances such as dust and sand, which can cause malfunctions by entering through gaps in the hinge area during folding and unfolding.
Innovation Solution
The implementation of a display device design that includes blocking members with protrusions on the rear covers of the hinge area, which are made of materials like silicon or plastic, to cover the gaps between the hinge cover and the rear covers, preventing foreign substances from entering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the hinge area is designed with gaps between the hinge cover and rear covers to allow folding movement, then the folding functionality is enabled, but foreign substances such as dust and sand can penetrate through these gaps causing malfunctions
Solution Approach 1:
The blocking member is designed with a specific local structure featuring multiple protrusions that create a filtering effect. This local quality modification allows the blocking member to selectively permit air flow while blocking foreign substances, thus resolving the contradiction between maintaining gaps for folding functionality and preventing foreign substance penetration.
Solution Approach 2:
The blocking member acts as an intermediary element positioned between the hinge cover and rear covers. It mediates the conflict by providing a structure that maintains the necessary gaps for folding while simultaneously blocking foreign substances, thus enabling both folding functionality and protection against contamination.
2Object-affected harmful factors
If blocking members are added to cover the gaps in the hinge area, then foreign substance penetration is prevented, but the device structure becomes more complex
Solution Approach 1:
The blocking member is integrated with the hinge cover or rear cover structure, merging the blocking function with the existing structural components. This integration reduces overall device complexity by combining multiple functions into a single element rather than adding separate blocking components.
Solution Approach 2:
The blocking member is designed as a thin structure with protrusions that can be easily manufactured and integrated. This thin-film approach minimizes the added complexity while effectively performing the blocking function, as the structure maintains flexibility and can be seamlessly incorporated into the hinge assembly.
3Object-affected harmful factors
If the blocking member uses a plate structure with protrusions to block foreign substances, then sealing effectiveness is improved, but manufacturing precision requirements increase
Solution Approach 1:
The protrusions on the blocking member are designed to preliminarily contact and seal with corresponding surfaces before the hinge reaches its fully closed position. This preliminary action ensures sealing effectiveness is achieved during the folding process, reducing the need for extremely high manufacturing precision in the final assembled state.
Solution Approach 2:
The blocking member's protrusions are designed with specific dimensional parameters (height, diameter, spacing) that can be optimized to achieve effective sealing. By carefully selecting these parameters, the design balances sealing effectiveness with manufacturing feasibility, allowing for adequate tolerances while maintaining blocking performance.
