Lighting Fixture Modular Buckle Assembly for Tool-Free Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting fixtures are difficult to assemble and disassemble, leading to time-consuming and potentially destructive processes, which affect reliability and safety, and result in material waste due to the need for replacing entire modules when only specific components need replacement.
Innovation Solution
An easily-assembled/disassembled lighting fixture design featuring a power supply module with a lifting ring and connecting assemblies, a lamp body with buckle assemblies, and an optical lens with buckling slots, allowing for modular connection and disconnection without tools, facilitated by screw-fastened connections and adjustable buckles for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If fully fixed connection methods (screws, glue bonding, ultrasonic welding) are used, then connection strength is improved, but disassembly difficulty increases and becomes time-consuming or destructive
Solution Approach 1:
The connection structure is divided into modular components: a connecting assembly with connecting members and buckling slots, and buckle assemblies with buckling blocks. This segmentation allows the connection to be divided into discrete, replaceable parts that can be easily assembled and disassembled without tools, resolving the contradiction between strong connection and easy disassembly.
Solution Approach 2:
The connection system transitions from a static, fixed connection to a dynamic, reversible connection. The buckle assemblies can be engaged and disengaged on demand, allowing the connection strength to be activated when needed and released when maintenance is required, eliminating the trade-off between permanent strength and ease of disassembly.
2Ease of repair
If fully modular design is used, then ease of replacement is improved, but material waste increases due to replacement of entire modules
Solution Approach 1:
The lighting fixture is segmented into independently replaceable components (power supply module, lamp body, optical lens) with standardized connection interfaces. This allows replacement of only the specific faulty component rather than entire modules, reducing material waste while maintaining ease of repair.
Solution Approach 2:
The buckle assemblies and connecting members serve multiple functions: they provide mechanical connection, enable tool-free assembly/disassembly, and allow for selective replacement of components. This universal connection interface supports both easy repair and material conservation by enabling precise component-level replacement.
3Reliability
If traditional fixed connections are used, then product reliability is maintained, but assembly time increases and maintenance efficiency decreases
Solution Approach 1:
The connecting members and buckle assemblies are pre-designed with complementary geometries (connecting blocks with buckling slots, positioning pins with positioning holes) that guide proper alignment during assembly. This preliminary design ensures reliable connection while enabling rapid, tool-free assembly and maintenance operations.
Solution Approach 2:
The traditional screw-based mechanical fastening system is replaced with a snap-fit buckle system that uses elastic deformation and geometric interlocking. This substitution maintains connection reliability through precise mechanical engagement while dramatically improving assembly and disassembly speed, thereby increasing productivity.

AI summary
The present disclosure discloses an easily-assembled/disassembled lighting fixture. A power supply module includes a power supply body, a lifting ring, and a first connecting assembly. A female power connector in the power supply body protrudes out of a bottom of the power supply body, the lifting ring is connected to a top of the power supply body in a threaded manner, and the first connecting assembly is fastened to the bottom of the power supply body by using a screw. The power supply module is buckled to a first buckle assembly at a top of a lamp body by using the first connecting assembly, and the female power connector is inserted into a male power connector inside the lamp body. An optical lens is buckled to a second buckle assembly at a bottom of the lamp body by using a first buckling slot.
