Waterproof Decorative Lamp Housing Installation Sequence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional decorative lamps face issues with poor waterproofing due to gaps between the illuminating body and lamp holder, inefficient production processes, and high material costs, which hinder automated production and reliability.
Innovation Solution
A waterproof decorative lamp design featuring an illuminating body with wires clamped between an isolation fixing column and a housing that sheaths the periphery of the column and body, allowing the housing to be installed from the front end, eliminating the need for wires to pass through the housing and enabling better waterproof sealing and improved production efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the housing abuts against the bottom end of the illuminating body to provide waterproof effect, then waterproof function is improved, but the production efficiency deteriorates due to complex assembly process
Solution Approach 1:
The patent inverts the traditional assembly sequence by first installing the illuminating body onto the wires, then installing the housing over the wires to abut against the illuminating body. This reversal eliminates the need for pre-assembled wire-housing units and enables automated production while maintaining waterproof sealing at the interface between the housing and illuminating body.
2Ease of manufacture
If the wires pass through the entire housing through through holes, then assembly is simplified, but waterproof function deteriorates when isolation means diameter is larger than illuminating body diameter
Solution Approach 1:
The patent introduces an isolation fixing column as an intermediary component that clamps the wires and provides a sealing interface. The housing abuts against this column and the illuminating body, creating a waterproof barrier without requiring wires to pass through the entire housing structure, thus maintaining both assembly simplicity and waterproof reliability.
3Adaptability or versatility
If the housing is installed from the rear of the illuminating body, then traditional processing manner is maintained, but production efficiency deteriorates due to inability to achieve integration of illuminating body and wires
Solution Approach 1:
The patent inverts the installation direction by having the housing installed from the front end rather than the rear. This allows the illuminating body to be directly mounted onto the wires first, then the housing is slipped over the assembly to abut against the illuminating body, enabling integration of components and automated production while maintaining processing flexibility.

AI summary
A waterproof decorative lamp includes an illuminating body having a first end, a second end opposite the first end, and an outer wall extending between the first end and the second end, a plurality of wires connected to the first end of the illuminating body, an isolation fixing column clamped between the plurality of wires, and a housing coupled to the isolation fixing column, the housing having an inner wall defining an inner cavity. The housing is installed from the second end of the illuminating body, the housing sheaths a periphery of the isolation fixing column and a periphery of first end of the illuminating body close to the wires, the second end of the illuminating body is exposed from the housing, the inner wall of the housing abuts against the outer wall of the illuminating body, and the wires are clamped between the isolation fixing column and the inner wall.
