Surface-Treated Electronic Housing for Anti-Slip Charging Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices, particularly those using battery packs, suffer from lubricity issues on their surfaces, which can lead to slipping and instability during charging or use.
Innovation Solution
Application of a surface-treating layer formed from a fluoro(poly)ether group-containing silane compound on at least a part of the device's surface, which includes specific chemical structures to enhance water and oil repellency, reduce friction, and improve stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a smooth hard plastic surface is used for the electronic device, then the surface is easy to clean and has good aesthetic appearance, but the surface becomes slippery and lacks anti-slip performance
Solution Approach 1:
The patent applies a thin film coating layer on the hard plastic surface that provides flexible anti-slip properties while maintaining the underlying smooth surface. The coating layer contains rubber-like particles or protrusions that create friction against contacting objects, preventing slippage during charging or use, while the base smooth surface remains easy to clean and aesthetically pleasing.
2Reliability
If an anti-slip unit such as a rubber-like sheet is provided on the charging surface, then anti-slip performance is improved, but the surface structure becomes more complex and may affect cleaning
Solution Approach 1:
The patent merges the anti-slip function directly into the surface coating layer rather than adding a separate rubber-like sheet. The coating layer integrates rubber-like particles or protrusions within a matrix material, combining the anti-slip functionality with the surface structure itself, thereby reducing overall device complexity while maintaining effective anti-slip performance and cleanability.
