Threaded Cylindrical Battery Box With Dual Waterproof Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing decorative lamp battery boxes used outdoors suffer from poor waterproofing due to cracking and inadequate sealing, especially when integrated with switch control boards, leading to short-circuit faults and limited power supply.
Innovation Solution
A cylindrical waterproof battery box design featuring a split structure with threaded fittings and dual waterproof sealing rings, along with a melt glue groove for sealing output lines, enhances sealing connectivity and aesthetic appeal while accommodating a switch circuit board compactly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the battery box is used outdoors with integrated switch control board and control line led out from connection position, then the power supply functionality is enhanced, but the waterproof effect deteriorates due to poor sealing at connection positions
Solution Approach 1:
The control line connection position is extracted and separately sealed from the main battery box body. The control line passes through a dedicated sealed conduit that is independently waterproofed, separating the electrical connection function from the waterproof enclosure to maintain both functionality and waterproof integrity.
Solution Approach 2:
A waterproof sealant or grommet is introduced as an intermediary element at the control line connection position. This intermediary component creates a waterproof barrier around the control line where it penetrates the battery box, allowing electrical connectivity while preventing water ingress at this vulnerable point.
2Ease of operation
If the box cover and compartment body are integrated with switch control board, then the control functionality is improved, but the waterproof performance deteriorates due to cracking and poor sealing
Solution Approach 1:
The battery box is segmented into distinct waterproof modules: the main battery compartment, the control board housing, and the sealing interface between them. Each module is independently designed for waterproof integrity, with standardized sealed connections that prevent cracking and maintain waterproof performance while allowing separate assembly and testing of control functionality.
3Reliability
If threaded fitting is used for connecting box cover and compartment body, then the sealing connectivity is improved, but the device complexity increases
Solution Approach 1:
The threading function and sealing function are merged into a single integrated component. The box cover or compartment body includes an integrated sealed threaded interface where the threading structure itself incorporates the sealing mechanism, eliminating the need for separate sealing elements and reducing overall structural complexity while maintaining reliable sealing connectivity.
