Twist-Lock Mounting Bracket for Adjustable Recessed LED Fixtures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED lighting fixtures face challenges in securely attaching to junction boxes and can lights while ensuring ease of installation and compliance with safety regulations, particularly in recessed lighting applications.
Innovation Solution
A twist-and-lock mechanism is employed for detachable attachment of the lighting fixture to a mounting bracket, which includes a twist-and-lock element and receptacle, and a biasing bracket with adjustable resilient members to fit various can light diameters, ensuring secure and adjustable mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a traditional fixed mounting bracket is used, then the structural stability is improved, but the adaptability to different can light diameters deteriorates
Solution Approach 1:
The mounting bracket incorporates resilient members that can dynamically adjust their compression state to accommodate different can light diameters. The resilient members are biased to extend and engage the interior surface of can lights of various sizes, allowing the bracket to adapt its shape while maintaining structural stability through the elastic properties of the resilient members.
Solution Approach 2:
The width adjustment members enable changing the effective width of the mounting bracket by adjusting the position of resilient members. This parameter change allows the same bracket to fit different can light diameters while maintaining secure engagement through controlled compression of the resilient members.
2Reliability
If a secure attachment mechanism is used, then the reliability of mounting is improved, but the ease of installation deteriorates
Solution Approach 1:
The twist-and-lock mechanism utilizes rotational motion to engage locking features that secure the lighting fixture to the mounting bracket. The twisting action engages cam surfaces or similar mechanical features that provide positive locking, ensuring reliable attachment while requiring only a simple rotational motion for installation and removal.
3Ease of manufacture
If a fixed-width mounting bracket is used, then the manufacturing simplicity is improved, but the adaptability to various junction box sizes deteriorates
Solution Approach 1:
The mounting bracket is divided into modular components including width adjustment members and resilient members that can be independently positioned. This segmentation allows the bracket to be manufactured with standardized parts that can be assembled in different configurations to accommodate various junction box sizes, maintaining manufacturing simplicity through component standardization.

AI summary
A twist-and-lock mounting bracket may secure a lighting fixture to a mounting surface. The twist-and-lock mounting bracket may define an aperture having features corresponding to the shape of a twist-and-lock element disposed on a housing of a lighting fixture. Accordingly, the twist-and-lock element may be configured to extend through the aperture while the corresponding features of the twist-and-lock element and the aperture are aligned. The housing may then be rotated such that the tabs do not align with the corresponding features of the aperture, and the twist-and-lock element is thereby prevented from sliding through the aperture. The mounting bracket may be secured to a junction box positioned within a mounting surface, or it may be secured to a biasing bracket having one or more second resilient members configured to engage the interior of a recessed can light, such that the lighting fixture may be secured to the recessed can light.
