Gasket for Mobile Device Touch Display Debris Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Touch sensitive displays in mobile devices are prone to degradation and contamination from environmental debris due to their portable nature, leading to mechanical issues and reduced responsiveness over time.
Innovation Solution
A gasket is used between the housing and the touch sensitive display subassembly, forming a seal to prevent debris entry and providing impact resistance, while allowing for flexible movement of the display, comprising a shedding portion to direct debris away and a centering portion for maintaining the display's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the touch sensitive display is made movable relative to the housing to enable touch detection, then the touch sensitivity and user interface functionality are improved, but the display becomes vulnerable to debris entry and mechanical degradation
Solution Approach 1:
A gasket is introduced as an intermediary component between the housing and the touch sensitive display assembly. The gasket serves as a protective barrier that prevents debris from reaching the display components while allowing the display to maintain its movable configuration for touch detection functionality.
Solution Approach 2:
The gasket is implemented as a flexible sealing element that can accommodate the movement of the touch sensitive display relative to the housing. This flexible film structure provides continuous protection against debris while maintaining the necessary mechanical freedom for touch operation.
2Object-affected harmful factors
If a seal is implemented between the housing and display to prevent debris entry, then protection against contamination is improved, but the movement and responsiveness of the display may be restricted
Solution Approach 1:
The gasket is designed as a flexible sealing element that can deform and move with the touch sensitive display assembly. This flexibility allows the seal to maintain contact with both the housing and display components while accommodating the movement required for touch detection, thus providing protection without restricting functionality.
Solution Approach 2:
The sealing system is designed to be dynamic rather than rigid, allowing the gasket to adapt its shape and position as the display moves. This dynamic sealing approach maintains protection against debris while enabling the necessary movement for touch operation.
3Adaptability or versatility
If the touch sensitive display is exposed to environmental conditions for portable use, then the portability and ease of operation are improved, but the mechanical components and responsiveness degrade over time
Solution Approach 1:
The gasket acts as a protective intermediary that shields the touch sensitive display components from direct exposure to environmental debris and contaminants. This barrier function helps maintain the mechanical integrity and responsiveness of the display components over time, thereby improving reliability while preserving portability.
Solution Approach 2:
The gasket provides beforehand protection by creating a sealed barrier that prevents debris from reaching and damaging the display components. This preventive measure cushions against the harmful effects of environmental exposure, reducing degradation and maintaining reliability during portable use.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The gasket effectively inhibits debris from entering the display assembly, maintains the display's responsiveness, and provides shock absorption, enhancing the operational life and durability of the mobile device.
Implementation Method 1
The gasket is attached to only one of the housing and the touch sensitive display subassembly. This gasket inhibits passage of debris between the housing and the touch screen display subassembly.
Implementation Method 2
A gasket is used between the housing and the touch sensitive display subassembly, forming a seal to prevent debris entry and providing impact resistance
