Waterproof Lamp Wire Inlet Sealing With Locking Nut Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lamps, particularly those used in wet or humid environments, have complex waterproof sealing structures that increase manufacturing costs and installation complexity due to multiple sealing designs for wire connections, which are exposed to the outside.
Innovation Solution
A waterproof lamp design featuring a single waterproof sealing ring at the wire inlet base, secured by a locking nut, simplifies the structure by eliminating the need for separate seals at the connection point of male and female terminals, and incorporates a funnel-shaped cavity for enhanced sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple waterproof sealing designs are implemented for wire inlet and connecting wire joint, then waterproof sealing performance is improved, but structural complexity and manufacturing cost increase
Solution Approach 1:
The patent combines the waterproof sealing functions for the wire inlet and the connecting wire joint into a single integrated sealing structure. The sealing component includes a first sealing ring at the wire inlet and a second sealing ring at the joint, both incorporated into one unified waterproof sealing assembly that is installed together with the connecting wire, thereby reducing the number of separate sealing designs while maintaining comprehensive waterproof protection.
2Reliability
If multiple waterproof sealing designs are implemented for wire inlet and connecting wire joint, then waterproof sealing performance is improved, but manufacturing cost increases
Solution Approach 1:
The patent integrates multiple sealing functions into a single manufacturable component assembly. The waterproof sealing structure is designed as one integrated unit containing both the first sealing ring for the wire inlet and the second sealing ring for the joint, which can be manufactured and assembled together in a single process, thereby reducing manufacturing complexity and cost while ensuring dual waterproof protection.
3Reliability
If multiple waterproof sealing designs are implemented for wire inlet and connecting wire joint, then waterproof sealing performance is improved, but installation complexity increases
Solution Approach 1:
The patent combines the installation of multiple waterproof sealing elements into a single integrated assembly process. The waterproof sealing structure, including both sealing rings and their positioning features, is pre-assembled as one unit that is installed together with the connecting wire in a single operation, thereby simplifying installation while providing comprehensive waterproof sealing at both the wire inlet and the joint.
