Adjustable Light Fixture Pivoting Housing and Retainer Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light fixtures lack the ability to efficiently direct the optical axis of the light source in various directions while being mounted to a ceiling, as they often require complex adjustments and do not accommodate different ceiling thicknesses effectively.
Innovation Solution
A light fixture design featuring a housing with a pivoting outer housing and a retainer mechanism that allows for adjustable positioning of the light source's optical axis, coupled with a flange and clamps that securely attach to ceilings of varying thicknesses, enabling easy direction and secure mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the light source is made adjustable to direct the optical axis in different directions, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The patent applies the dynamics principle by making the outer housing pivotable relative to the inner housing, allowing the light source to be dynamically adjusted to different directions. The retainer mechanism enables the optical axis to be moved from an initial position to an adjusted position, transforming a static fixture into a dynamically adjustable one without requiring complex adjustment mechanisms
2Volume of moving object
If the housing is made compact to fit through ceiling apertures, then the volume is reduced, but the stability of mounting on ceilings of varying thicknesses deteriorates
Solution Approach 1:
The patent applies the dimensionality change principle by extending the flange in a direction perpendicular to the main housing body. This allows the mounting interface to extend beyond the compact housing volume, providing stable attachment to ceilings of varying thicknesses without increasing the space required for installation through ceiling apertures
3Ease of manufacture
If the flange outer dimension is increased to provide stable mounting, then the ease of installation is improved, but the volume of the housing increases
Solution Approach 1:
The patent applies the segmentation principle by separating the housing into distinct components: a compact inner housing containing the light source, and an outer housing with an extended flange for mounting. This segmentation allows the flange to be optimized for installation stability while the inner housing remains compact for easy installation through ceiling apertures

AI summary
A light fixture including a light source having an optical axis and a housing having an inner housing and an outer housing. The outer housing pivots on the inner housing and the light source is coupled to the outer housing for pivotal movement with the outer housing relative to the inner housing to move the optical axis relative to the inner housing. A retainer coupled to the housing and a portion of the retainer is movable in a direction toward the outer housing to inhibit movement of the outer housing relative to the inner housing to hold a position of the optical axis.
