Light Fixture Connection Assembly Water Leakage Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light fixture connection assemblies fail to effectively protect electrical wiring from water leakage, leading to potential electrical hazards and reduced operational lifetime in outdoor and high-humidity environments.
Innovation Solution
A light fixture connection assembly featuring a stem with an internal threaded segment and two connectors, where one connector engages the stem and another engages the light fixture shade, creating a sealed passage for electrical wiring to pass through, reducing water leakage and enhancing protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional metal fasteners are used to attach the light fixture shade, then the shade can be securely mounted, but the electrical wiring is exposed to water leakage and environmental damage
Solution Approach 1:
The patent combines the mounting function and the wiring protection function into a single integrated connection assembly. The housing simultaneously secures the light fixture shade and encloses the electrical wiring within its internal cavity, eliminating the need for separate fasteners and providing comprehensive protection against water leakage and environmental damage.
Solution Approach 2:
The electrical wiring is nested within the internal cavity of the housing, which is itself nested within the connection assembly structure. The light fixture shade is mounted on the external surface of the housing, creating a nested arrangement where the housing protects both the shade attachment and the wiring from water and environmental exposure.
2Object-affected harmful factors
If the connection assembly is designed to protect wiring from water, then water leakage is reduced, but the structure becomes more complex with additional components
Solution Approach 1:
The housing integrates multiple functions: it serves as the mounting structure for the light fixture shade, the enclosure for electrical wiring protection, and the sealing barrier against water leakage. This consolidation reduces the number of separate components needed while maintaining comprehensive protection.
Solution Approach 2:
The patent employs sealing elements such as gaskets or O-rings (flexible shells/films) between the housing and the light fixture shade to create an effective water barrier. These flexible sealing components conform to the mating surfaces and prevent water infiltration without requiring complex multi-layer structures.
3Ease of operation
If threaded fasteners are used for mounting, then installation is straightforward, but the connection may loosen over time due to gravity and external forces
Solution Approach 1:
The housing combines the mounting interface and the wiring enclosure into a single integrated structure, providing both secure attachment and stable wiring protection. The unified structure resists loosening better than separate fastener components.
Solution Approach 2:
The housing is pre-configured with mounting features such as external threads or attachment mechanisms that facilitate straightforward installation. The wiring is pre-routed through the housing structure, allowing for easy assembly without requiring complex sequencing of operations.

AI summary
A light fixture connection assembly includes an internally threaded stem and two connectors that couple with a top surface and a bottom surface of a light fixture shade. Bores throughout the stem and connectors define a passageway for electrical wiring connected to a light sourced within the light fixture shade. The connection assembly reduces water-leakage into the hollow passage, and prevents electrical hazards and premature termination of the useable life of the light fixture.
