Detachable Lighting Assembly With Elastic Engaging Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flat lighting devices require complete replacement due to difficulties in detaching and identifying malfunctioning components, leading to inefficiency and waste.
Innovation Solution
A detachable assembly structure with engaging elements and elastic elements allows components to be easily attached and detached, using an actuator to facilitate quick disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the light-emitting units and driver are firmly mounted in the frame, then the structural stability is improved, but the ease of repair deteriorates
Solution Approach 1:
The patent divides the lighting device into separable modules: the frame assembly (with light guide plate) and the component assembly (with light-emitting units and driver). The engaging elements enable these modules to be firmly connected during operation but easily separated for maintenance, resolving the contradiction between structural stability and ease of repair.
2Reliability
If the whole set of lighting device is replaced, then the reliability is improved, but the loss of substance worsens
Solution Approach 1:
The patent enables extraction of only the malfunctioning component assembly (containing light-emitting units or driver) from the frame assembly. This allows replacement of only the necessary parts rather than the entire device, improving resource utilization and reducing waste while maintaining system reliability.
3Stability of the object's composition
If the light-emitting units and driver are firmly fixed, then the stability is improved, but the ease of operation worsens
Solution Approach 1:
The patent transforms the static connection into a dynamic one through the elastic element and engaging elements. The connection is firm during normal operation but can be quickly released by actuating the engaging elements, providing both stability and ease of operation.

Function Achieved in This Case
Enhances maintenance convenience, reduces waste, and prolongs the service life of lighting devices by enabling individual component replacement and reuse.
Implementation Method 1
The elastic element is mounted in the second component and disposed between the two engaging elements, and is capable of pushing the two engaging elements along the abutting direction

AI summary
A lighting device comprises a first component, a second component, at least one assembling module, at least one light guide plate, and at least one light-emitting unit. The assembling module is mounted at the second component and comprises an elastic element and at two engaging elements, which are moveable along an abutting direction. The elastic element pushes the engaging elements along the abutting direction, such that the engaging elements extend out from the second component and abut against at least one matching portion of the first component along the abutting direction to detachably assemble the second component to the first component along an assembling direction, which is nonparallel to the abutting direction. The at least one light guide plate is mounted at the first component, and the at least one light-emitting unit is mounted at one of the second component and the engaging element of the assembling module and faces the light guide plate.
