Rotational LED Lamp Body for Bathtub Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED underwater lamps for bathtubs are cumbersome to replace due to the need to remove the entire housing for maintenance, and the waterproofing process is inefficient.
Innovation Solution
The LED underwater lamp features a housing with a rotational fastening structure that allows the LED lamp body to be easily rotated in and out for replacement, utilizing internal and external sealing rings for enhanced waterproofing, and a detachable power line connection for simplified maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the LED lamp body is directly mounted into a hole in the bathtub wall through a retaining nut, then the mounting structure is simple, but the replacement process becomes troublesome and time-consuming requiring the whole outer housing to be opened
Solution Approach 1:
The product is divided into two independent parts: a fixed housing that remains mounted on the bathtub wall, and a replaceable LED lamp body. This segmentation allows the housing to stay in place while only the lamp body needs to be replaced, eliminating the need to open the entire outer housing during maintenance.
Solution Approach 2:
The LED lamp body is extracted as a separate removable component from the housing. The housing contains mounting features (threaded holes, sealing structures) that remain fixed, while the lamp body can be independently removed and replaced through the opening in the housing without affecting the housing itself.
2Device complexity
If the LED lamp body is directly mounted into a hole in the bathtub wall through a retaining nut, then the mounting structure is simple, but water-proof treatment needs to be carried out after replacement which reduces efficiency
Solution Approach 1:
The waterproof sealing structures (sealing rings, sealed cavities) are pre-integrated into the housing and lamp body design during manufacturing. The housing includes pre-installed sealing rings at the opening, and the lamp body has sealed cavities that maintain waterproofing without requiring additional waterproofing operations after replacement.
3Device complexity
If the LED lamp body is directly mounted into a hole in the bathtub wall through a retaining nut, then the mounting structure is simple, but the retaining nut has to be screwed off from an inner side of the bathtub which is troublesome
Solution Approach 1:
The housing acts as an intermediary component between the bathtub wall and the LED lamp body. The housing contains threaded holes and mounting features that secure the lamp body, eliminating the need to access the inner side of the bathtub for mounting or maintenance operations.
