Sliding Bracket Mechanism for Ceiling Light Shade Servicing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light fixtures with glass or plastic shades require disassembly for cleaning and bulb replacement, which is difficult, time-consuming, and poses risks of breakage and injury.
Innovation Solution
A sliding hanger bracket system that allows the light shade to lower and tilt without disassembling the fixture, using a dual bracket assembly with pinned connections for secure holding and easy access for servicing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the light shade is fixed to the fixture using rotatable fasteners, then the light fixture maintains structural stability, but disassembly for cleaning and bulb replacement becomes difficult and time-consuming
Solution Approach 1:
The patent applies a sliding bracket mechanism that transforms the static fixed connection into a dynamic movable connection. The bracket can slide between a locked position (providing structural stability) and an unlocked position (enabling easy servicing). This dynamic mechanism resolves the contradiction by allowing the connection type to change based on operational needs.
Solution Approach 2:
The invention segments the light fixture into modular components: the fixed ceiling mounting bracket, the movable sliding bracket, and the detachable light shade assembly. This segmentation allows independent movement and servicing of the shade without affecting the ceiling mounting, resolving the contradiction between stability and ease of servicing.
2Ease of operation
If the light shade is disassembled for cleaning and bulb replacement, then servicing access is improved, but the risk of breakage and injury increases
Solution Approach 1:
The sliding bracket serves as an intermediary mechanism between the ceiling mounting and the light shade. Instead of directly disassembling the shade from the ceiling fixture, the user manipulates the intermediate bracket to lower the shade assembly safely. This intermediary mechanism provides controlled access while maintaining safety, reducing the risk of breakage and injury.
3Ease of operation
If traditional fixed light fixtures are used, then the fixture appearance remains simple and undistinguishable, but servicing requires complete disassembly
Solution Approach 1:
The sliding bracket mechanism is designed to be visually concealed when in the locked position, making the fixture appear simple and traditional. The dynamic element only becomes visible during the servicing process when the bracket slides to unlock and lower the shade. This maintains aesthetic simplicity while providing enhanced servicing convenience.

AI summary
Devices, apparatus, fixtures, systems and methods of using a sliding hanger bracket for overhead lights that allows the light shade, such as a glass bowl, to lower away from a ceiling fan or light base, and tilt allowing the light shade to be cleaned and change light sources, such as the light bulbs, without having to disassemble the light fixture. The hanger bracket can have an up position locked in place where the outside of the overhead light appears undistinguishable from traditional ceiling light fixtures or lights on ceiling fans.
