Elastic Latch Sealing Assembly for Underwater Electronic Components
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing underwater sealing structures for electronic components require professional operation and are inconvenient for frequent assembly and disassembly due to the need for screw-driven mechanisms, leading to lengthy assembly times and poor user experience.
Innovation Solution
A sealing assembly comprising a sealing seat with a mounting chamber and a sealing shell, where the shell has a first connection channel and a surrounding gasket, and an elastic latch that aligns and compresses to ensure sealing communication, eliminating the need for multiple screws and tools for assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw-driven terminal face sealing mode is used, then sealing reliability is improved, but operation convenience deteriorates and assembly time increases
Solution Approach 1:
The patent replaces the screw-driven mechanical sealing system with an elastic latch-based mechanical system. The elastic latch uses elastic deformation to provide sealing force, eliminating the need for screw threads and screwdrivers. This substitution maintains sealing reliability through elastic pressure while dramatically improving operation convenience by enabling tool-free assembly and disassembly.
Solution Approach 2:
The patent changes the sealing mechanism from rigid screw pressure to elastic pressure. The elastic latch utilizes elastic material properties to provide continuous sealing pressure that can accommodate dimensional variations and thermal expansion, improving both reliability and ease of operation compared to rigid screw fastening.
2Reliability
If screw-driven terminal face sealing mode is used, then sealing reliability is improved, but assembly time increases
Solution Approach 1:
The replacement of screw-driven mechanism with elastic latch system eliminates the time-consuming steps of threading, tightening, and tool handling. The elastic latch can be quickly engaged and disengaged by hand, reducing assembly time while maintaining sealing reliability through elastic pressure.
Solution Approach 2:
The elastic latch is pre-formed with the necessary elastic properties during manufacturing, so no additional tightening or adjustment is needed during assembly. The sealing force is automatically provided by the elastic recovery of the material, eliminating the time required for screw tightening operations.
3Reliability
If screw-driven terminal face sealing mode is used, then sealing reliability is improved, but device complexity increases
Solution Approach 1:
The patent replaces the complex screw thread geometry, multiple fastening points, and tool interfaces with a simple elastic latch structure. This substitution reduces the number of parts and assembly steps while maintaining sealing reliability through the elastic material's ability to provide consistent sealing pressure.
Solution Approach 2:
The elastic latch combines multiple functions into a single component: it provides both the sealing force and the locking mechanism. The elastic deformation of the latch simultaneously achieves contact pressure for sealing and mechanical engagement for retention, simplifying the overall structure compared to separate screw fasteners and sealing elements.

AI summary
A sealing assembly for electronic components including a sealing seat and a sealing shell for mounting the electronic component. The sealing shell is received through an opening in the top of the sealing seat and into complementary mounting chamber. A left end of the sealing shell includes a first connection channel; a left end of the mounting chamber includes a second connection channel and a sealing gasket surrounding the second connection channel. A right end of the mounting chamber includes an elastic latch. After installing the sealing shell in the mounting chamber, the elastic latch laterally abuts the sealing shell's right end and is in a lateral compression position, and the first connection channel and the second connection channel are aligned and in sealing communication through the sealing gasket. The elastic latch includes a right backstop to prevent the sealing shell from being vertically detached from the mounting chamber.
