Multifunctional Mobile Terminal Casing Clamping Waterproofing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile terminal protective casings lack sufficient waterproof and dustproof properties, making it inconvenient for users to use their devices in wet conditions, and current solutions are either too complex or costly to meet this need.
Innovation Solution
A multifunctional mobile terminal protective casing design featuring a rear cover with a transparent polycarbonate plate, a middle frame, and a front cover with clamping mechanisms that form a receiving chamber, utilizing clamping slots and bulges for secure and waterproof sealing without the need for a sealing ring, along with additional features like rope hanging holes and soft rubber buttons for enhanced usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sealing ring is used to achieve waterproofing, then waterproof property is improved, but device complexity increases and sealing ring retention problems occur during disassembly
Solution Approach 1:
The patent removes the sealing ring component entirely from the protective casing design. Instead of using a sealing ring to achieve waterproofing, the invention employs a clamping mechanism with clamping slots and clamping bulges that directly clamp the mobile terminal, eliminating the need for a separate sealing ring and thus resolving the retention problem during disassembly.
Solution Approach 2:
The patent introduces a clamping mechanism consisting of clamping slots and clamping bulges as an intermediary structure between the protective casing and the mobile terminal. This clamping mechanism achieves both waterproofing and secure attachment without requiring a sealing ring, thereby simplifying the overall device structure while maintaining reliability.
2Reliability
If a complicated protective casing is designed to achieve waterproofing, then waterproof property is improved, but ease of operation deteriorates
Solution Approach 1:
The protective casing is divided into multiple components including a front cover, rear cover, and middle frame with integrated clamping mechanisms. This segmentation allows for easy assembly and disassembly by simply clamping and releasing the components, improving ease of operation while maintaining waterproof integrity through the clamping slots and bulges design.
3Ease of operation
If a simple protective casing is used, then ease of operation is improved, but waterproof property deteriorates
Solution Approach 1:
The patent applies local quality by concentrating the waterproofing function in specific areas where the clamping slots and clamping bulges make direct contact with the mobile terminal. This localized approach achieves effective waterproofing at the critical interfaces without requiring complex waterproofing measures throughout the entire structure, thus maintaining simplicity and ease of operation.
