Offset Clamping Light Fixture for Variable Ceiling Thickness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light fixtures struggle to securely attach to ceilings of varying thicknesses, often requiring complex installation procedures and multiple adjustments to ensure proper fit and stability.
Innovation Solution
A light fixture design featuring a housing with a flange and adjustable clamps that include offset clamping surfaces, allowing for secure attachment to ceilings of different thicknesses through a single screw mechanism, enabling easy adjustment and repositioning of the light source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional light fixtures use fixed clamps, then installation is simple, but they cannot accommodate ceilings of varying thicknesses
Solution Approach 1:
The clamp is designed with movable components that allow adjustment of the clamping surfaces relative to each other. The clamp body can slide along the ceiling surface, and the clamping arm can pivot to change the distance between clamping surfaces, enabling adaptation to different ceiling thicknesses while maintaining a relatively simple overall structure
Solution Approach 2:
The distance between the first and second clamping surfaces is made variable through mechanical adjustment mechanisms. By changing the positional parameter of the clamping surfaces relative to each other, the fixture can accommodate different ceiling thicknesses without requiring multiple different clamp designs
2Adaptability or versatility
If multiple fasteners are used to accommodate different ceiling thicknesses, then adaptability improves, but installation complexity and time increase
Solution Approach 1:
The single clamp structure serves multiple functions by incorporating adjustable clamping surfaces that can accommodate various ceiling thicknesses. This universal design eliminates the need for multiple different fasteners or adjustment mechanisms, allowing installers to use one component for all ceiling thickness scenarios
Solution Approach 2:
The clamp is pre-designed with offset clamping surfaces positioned to accommodate a range of ceiling thicknesses. The adjustable mechanism is built into the clamp structure beforehand, allowing for quick on-site adjustment without requiring additional fasteners or complex installation procedures
3Adaptability or versatility
If the clamp has fixed clamping surfaces, then manufacturing is simple, but it cannot securely attach to ceilings of different thicknesses
Solution Approach 1:
The clamp incorporates movable elements such as sliding blocks or pivoting arms that allow the clamping surfaces to adjust their relative positions. These dynamic components can be manufactured using standard machining processes and assembled into the clamp body, adding adaptability without significantly increasing manufacturing complexity
Solution Approach 2:
The clamp is divided into separate adjustable components rather than a single rigid piece. This segmentation allows each component to be manufactured independently using conventional processes, then assembled to create the adjustable clamping mechanism, balancing manufacturability with adaptability

AI summary
A light fixture including a housing having a longitudinal axis, the housing configured to be received in an aperture of a ceiling. A flange extends from the housing. A clamp is movable relative to the housing and the flange in a direction along the longitudinal axis toward the flange. The clamp includes a first clamping surface and a second clamping surface, the second clamping surface spaced an offset distance from the first clamping surface measured along the longitudinal axis. The first clamping surface is configured to clamp the ceiling between the first clamping surface the flange when the ceiling has a first thickness and the second clamping surface is configured to clamp the ceiling between the second clamping surface and the flange when the ceiling has a second thickness greater than the first thickness.
