Ceiling Lamp Fixation Assembly Without Cover Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ceiling lamp designs with light guide plates face challenges in assembly convenience and cost due to complex structures and the need to open lamp covers during assembly, leading to increased costs and assembly difficulties.
Innovation Solution
A ceiling lamp design featuring a board assembly and lamp body assembly connected via a fixation assembly, where the lamp body assembly is fixed to the board assembly without opening the lamp cover, utilizing a cross-shaped connecting board, bending sheet, optical diffuser, light guide plate, aluminum board, and reflector board, with a buckle mechanism for secure locking, and an assembly method involving screwing, welding, and placement of components within a round tray.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the lamp cover is opened during assembly, then the components can be installed, but the assembly process becomes complicated and time-consuming
Solution Approach 1:
The ceiling lamp is divided into two main assemblies: the board assembly (containing drive, LED luminescent plate, dustcoat) and the lamp body assembly (containing lamp cover, light guide plate, optical diffuser, reflector board, backboard). These assemblies are manufactured separately and then connected through the fixation assembly, allowing parallel production and simplified final assembly without opening the lamp cover.
Solution Approach 2:
The fixation assembly acts as an intermediary connection mechanism between the board assembly and lamp body assembly. It includes the cross-shaped connecting board with bending sheets that extend into the lamp cover, providing a mediator that enables secure connection without requiring disassembly of the lamp cover.
2Reliability
If the lamp body is securely fixed to the ceiling, then the lamp remains stable, but the assembly structure becomes complex
Solution Approach 1:
The fixation function is segmented into multiple components: the cross-shaped connecting board provides structural support, the bending sheets provide mechanical engagement with the lamp cover, and the brinks provide positioning. This segmentation allows each component to perform its specific function efficiently while maintaining overall simplicity.
Solution Approach 2:
Instead of fixing the lamp body to the ceiling directly, the invention inverts the approach by having the board assembly (with connecting board and bending sheets) engage with the lamp cover from the inside, creating a self-locking mechanism that secures the lamp body to the ceiling through the fixation assembly.
