Ceiling Fitting Lighting Module Segmentation for Replaceability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ceiling fittings require replacement of the entire unit when either the light source or canopy is worn out, leading to increased costs due to the integral combination of these components.
Innovation Solution
A ceiling fitting design featuring a canopy with a movable hook and a removably mounted lighting module, allowing individual replacement and maintenance of the lighting module and canopy, facilitated by a locking mechanism with retaining grooves and hooks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the light source and canopy are combined integrally, then the structural simplicity is improved, but the replaceability and maintenance cost worsen
Solution Approach 1:
The ceiling fitting is divided into separate modules: the canopy assembly (with mounting hole and fixed hook) and the lighting module (with lamp board, light permeable shell, and retaining grooves). This segmentation allows the lighting module to be replaced independently without replacing the entire ceiling fitting, resolving the contradiction between structural simplicity and replaceability.
2Ease of manufacture
If the light source and canopy are combined integrally, then the manufacturing process is simplified, but the replacement cost increases
Solution Approach 1:
By segmenting the ceiling fitting into canopy and lighting module components with standardized interfaces (hooks and retaining grooves), the manufacturing process remains simple while enabling selective replacement of only the worn lighting module, thereby reducing replacement costs compared to replacing the entire integrated unit.
3Ease of repair
If a removable lighting module is used, then the replaceability is improved, but the assembly complexity increases
Solution Approach 1:
The movable hook mounted on the canopy provides a dynamic locking mechanism that simplifies assembly and disassembly. The hook can be easily actuated to release the lighting module, making the replacement process simple despite the modular design. This dynamic element reduces the perceived assembly complexity while maintaining high replaceability.
4Ease of operation
If a locking mechanism with movable hook is used, then the ease of disassembly is improved, but the device complexity increases
Solution Approach 1:
The movable hook provides a simple dynamic mechanism for easy disassembly. When pressure is applied to the movable hook, it releases from the retaining groove, allowing quick removal of the lighting module. This single movable component achieves ease of operation without significantly increasing overall device complexity.

AI summary
A ceiling fitting includes a canopy provided with a fixed hook and a mounting hole, a movable hook mounted on the mounting hole of the canopy and having an arcuate restriction portion, a lighting module removably mounted on the canopy, and an outer cover covering the lighting module. The lighting module includes a lamp board mounted on the canopy and located between the movable hook and the fixed hook, and a light permeable shell mounted on the lamp board. The lamp board is provided with a first retaining groove and a second retaining groove. The first retaining groove is locked onto the movable hook, with the restriction portion of the movable hook being retained by the first retaining groove of the lamp board. The second retaining groove is locked onto the fixed hook.
