Wireless Locator Case Sealing for Waterproof Dust Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing AirTag protection cases lack adequate waterproofing and dustproofing, leading to potential damage and reduced service life due to liquid and dust penetration through gaps in the protection cover and housing.
Innovation Solution
A wireless location device protection apparatus featuring a protection element with a first and second base portion forming an inner space, a cover body that fits with the wireless device to form a face contact seal, and non-planar interface designs to enhance waterproofing, including annular grooves and protrusions for improved sealing and alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protection cover is added to shield the window, then the protective capability is improved, but gaps exist between the cover and housing allowing liquid penetration
Solution Approach 1:
A waterproof film is introduced to cover the window opening, creating a flexible barrier that prevents liquid penetration while allowing signal transmission. The film is stretched across the window opening and secured between the protection cover and housing, providing continuous coverage without gaps.
Solution Approach 2:
The waterproof film acts as an intermediary element between the protection cover and housing, filling the functional gap and preventing liquid penetration paths that would otherwise exist between these rigid components.
2Reliability
If the window is exposed for signal transmission, then communication stability is improved, but dust accumulation and waterproofing are compromised
Solution Approach 1:
A transparent or translucent waterproof film is used to cover the window opening, maintaining signal transmission capability while providing a barrier against dust and liquid. The film's flexibility allows it to conform to the window shape while maintaining continuous coverage.
3Reliability
If a protection cover is incorporated, then shielding capability is improved, but the structure becomes more complex
Solution Approach 1:
The waterproof film is integrated into the existing protection cover assembly, combining the shielding function with the waterproofing function in a unified structure. The film is stretched and secured within the existing components rather than adding separate independent elements.
