USB Quick Connector Waterproof Housing Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional USB quick connectors lack a waterproof function, allowing water to enter and cause electric leakage, which damages and shortens the lifespan of electronic appliances.
Innovation Solution
A USB quick connector design featuring a housing with a rechargeable battery, circuit board, and plug, along with first and second waterproof gaskets to prevent water entry into the USB ports and the clearance between covers, respectively, ensuring protection against moisture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional USB quick connector design is used, then device simplicity is maintained, but waterproof function is lacking and water can enter USB ports causing electric leakage
Solution Approach 1:
The housing is divided into multiple components (first cover, second cover, side plate) with distinct functions. The first cover protects the USB ports, the second cover houses internal components, and the side plate provides additional protection. This segmentation allows each part to be optimized for its specific protective function while maintaining overall device reliability.
Solution Approach 2:
Waterproof gaskets are introduced as intermediary elements between different housing components and around USB ports. These gaskets create waterproof barriers without requiring complete redesign of the housing structure, thus improving reliability while minimizing complexity increase.
2Reliability
If waterproof gaskets are added to USB ports, then protection against water entry is improved, but manufacturing complexity increases
Solution Approach 1:
The waterproof gaskets are pre-installed onto the circuit board during the manufacturing process, before final assembly. This preliminary action ensures proper positioning and sealing effectiveness while simplifying the final assembly process, as the gaskets are already in place and require minimal additional steps to complete the waterproofing.
3Reliability
If multiple covers and plates are used to create waterproof housing, then water protection is enhanced, but device assembly complexity increases
Solution Approach 1:
Multiple protective elements (first cover, second cover, side plate) are merged into a unified housing structure that works together as an integrated waterproof system. The side plate connects and reinforces both covers, creating a cohesive protective enclosure that enhances waterproofing without requiring entirely separate assembly processes for each component.

AI summary
A USB quick connector includes a housing, a rechargeable battery mounted in the housing, a circuit board mounted in the housing, and a plug connected with the housing. The circuit board is provided with two USB ports. The housing includes a first cover, a second cover combined with the first cover, a side plate mounted on and covers the first cover and the second cover, a first waterproof gasket mounted on and surrounding the USB ports of the circuit board, and a second waterproof gasket located between and surrounding the first cover and the second cover. A receiving space is formed between the first cover and the second cover. The rechargeable battery and the circuit board are arranged in the receiving space.
