Pivoting Light Fixture Wiring With Concealed Internal Passage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical fixtures face challenges in forming conductive connections due to difficult installation, lack of aesthetic appeal, and conductive connections that fail with repeated pivoting, making it hard for tradesmen and DIY users to wire fixtures in a serial or daisy chain manner.
Innovation Solution
The electrical fixtures incorporate integral junction boxes in the mounting portion, allowing easy and reliable pivoting and rotational adjustment, with concealed connections that protect conductors from the elements, and passages within the fixture to facilitate wiring without external exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If prior art electrical fixtures use external junction boxes or exposed wiring methods, then conductive connections can be formed, but aesthetic appeal deteriorates and installation difficulty increases
Solution Approach 1:
The patent combines the junction box function with the fixture housing itself, creating an integral junction box that is built into the mounting portion. This eliminates the need for separate external junction boxes while providing both functional wiring capability and aesthetic integration into the fixture design.
Solution Approach 2:
The patent introduces an integral junction box as an intermediary structure within the fixture housing that mediates between the external wiring environment and the internal fixture components. This intermediary structure provides a protected, organized space for conductive connections while maintaining aesthetic appearance from the exterior.
2Adaptability or versatility
If prior art fixtures allow repeated pivoting adjustment, then directional flexibility is improved, but conductive connections fail due to repeated movement
Solution Approach 1:
The patent segments the fixture into distinct functional zones: a fixed mounting portion containing the integral junction box and a movable emitting portion that can pivot. This segmentation isolates the conductive connections in the fixed portion from the mechanical stress of pivoting, allowing directional adjustment without compromising connection reliability.
Solution Approach 2:
The patent introduces a passage as an intermediary pathway that allows conductors to extend from the fixed mounting portion to the movable emitting portion. This passage is configured to accommodate conductor movement during pivoting while preventing direct exposure to environmental elements, thus maintaining both flexibility and reliability.
3Device complexity
If fixtures are wired in serial or daisy chain manner, then single conductor connection is simplified, but installation difficulty increases due to complex wiring formation
Solution Approach 1:
The patent designs the integral junction box with universal connectivity features that support multiple wiring configurations including serial and daisy chain arrangements. The standardized structure allows tradesmen and DIY users to easily form conductive connections in various configurations without requiring complex installation procedures.

AI summary
An electrical fixture is provided that includes a mounting portion, an emitting portion, a connection, and a passage. The mounting portion has a first chamber and an opening passing from the first chamber to an exterior of the electrical fixture. The emitting portion has a second chamber. The connection secures the mounting and emitting portions to one another for movement with respect to one another. The passage has a first end that begins in the first chamber, an extension passing from the first chamber through the connection without passing through the exterior of the electrical fixture, and a second end that terminates in the second chamber.
