Display Device Accommodating Groove Dust Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices with cameras suffer from dust pollution issues due to the use of compressed foam, which can cause pressing water ripples on the screen when compressed.
Innovation Solution
A display device design that includes a housing with a first opening, a display component with a second opening aligned with the first, and a first dust-proof part located between the display component and the housing. The housing has an accommodating groove for the dust-proof part, reducing pressure on the display component and minimizing reverse forces that cause water ripples.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If compressed foam is used to seal the gap between the camera and housing, then dust-proof sealing is achieved, but pressing water ripples occur on the screen
Solution Approach 1:
The patent extracts the compressed foam from the gap between the camera and housing, and relocates it to the gap between the screen and housing. This separation removes the harmful compression effect from the camera assembly while preserving the dust-proof sealing function in the screen gap, thereby eliminating pressing water ripples on the screen.
Solution Approach 2:
The patent introduces a rubber buffer as an intermediary component between the screen and housing. This rubber buffer provides both dust-proof sealing and mechanical cushioning, eliminating the need for compressed foam in the camera gap and preventing pressing water ripples while maintaining effective sealing.
2Reliability
If compressed foam is used to seal the gap between the screen and housing, then dust-proof sealing is achieved, but the foam compression causes reverse force and water ripples
Solution Approach 1:
The patent removes the compressed foam from the camera-housing gap and relocates it to the screen-housing gap. This extraction eliminates the source of reverse force and water ripples in the camera assembly while maintaining the dust-proof sealing function in the screen gap.
Solution Approach 2:
The patent changes the material parameter from compressed foam to rubber buffer. The rubber buffer provides more compliant and distributed sealing pressure, reducing localized compression forces and reverse forces that cause water ripples, while maintaining effective dust-proof sealing.
