Waterproof Mobile Phone Sleeve Sealing Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile phone protective sleeves with waterproof functions have complex disassembly and assembly procedures, leading to low waterproof performance and reliability, making them difficult to use effectively, especially in scenarios like underwater shooting.
Innovation Solution
A mobile phone protective sleeve with a novel waterproof structure featuring a lower cover, upper cover, and screen protection sheet, utilizing L-shaped sealing surfaces and a sound-dialing knob assembly with a waterproof sealing ring, along with a charging padding and protective foam, to ensure easy assembly, improved waterproof stability, and visual confirmation of proper assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If waterproof sealing rings are used to achieve waterproof function, then waterproof performance is improved, but device complexity and assembly difficulty increase
Solution Approach 1:
The patent extracts the traditional waterproof sealing ring from the system and replaces it with a waterproof coating layer applied directly to the housing surface. This eliminates the separate sealing ring component while maintaining waterproof functionality, thereby reducing structural complexity and assembly steps.
Solution Approach 2:
The patent replaces the mechanical waterproof sealing ring with a chemical/physical waterproof coating layer. Instead of using a separate mechanical sealing component, the housing surface itself is treated with a waterproof coating, substituting a mechanical sealing system with a surface treatment approach.
2Reliability
If traditional waterproof sealing rings are used, then waterproof function is achieved, but assembly and disassembly procedures become complex and error-prone
Solution Approach 1:
By removing the separate waterproof sealing ring component, the patent eliminates the assembly steps of installing and positioning the sealing ring. The waterproof coating is applied as an integral part of the housing, simplifying assembly procedures and reducing the risk of assembly errors.
Solution Approach 2:
The patent merges the waterproof sealing function directly into the housing structure through coating application. Instead of assembling a separate sealing ring onto the housing, the waterproof function is combined with the housing itself, making assembly simpler and more intuitive.
3Reliability
If waterproof sealing rings are used, then waterproofness is achieved, but assembly deviation is difficult to detect and waterproofness failure occurs
Solution Approach 1:
The patent applies waterproof coating layers with different colors to different components (housing and cover). This color differentiation provides visual feedback during assembly, making it easy to detect assembly deviations and ensure proper alignment, thereby eliminating the difficulty of detecting assembly errors.

AI summary
The present disclosure provides a mobile phone protective sleeve with a novel waterproof structure. The mobile phone protective sleeve with the novel waterproof structure comprises a lower cover, an upper cover and a screen protection sheet hermetically connected to the upper cover, wherein the lower cover comprises a base plate and a lower cover mounting sleeve, a sealing groove is formed in the inner wall of the lower cover mounting sleeve circumferentially, the base plate is arranged at the middle part of the lower cover mounting sleeve, and the upper cover comprises an internal part hard rubber frame, an external part hard rubber frame and a soft rubber frame arranged on the outer side of the external part hard rubber frame. The waterproof stability can be effectively guaranteed through the external part hard rubber frame and the internal part hard rubber frame.
