Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lamp apparatuses face issues with clamping member deformation leading to potential frame detachment from the ceiling and complex user handling due to the clamping member's placement between the lamp holder and the ceiling.
Innovation Solution
A coupling device with a resilient member and adjusting members that interconnect frames via accommodation spaces, applying outward forces to secure the frames together, allowing for easy assembly and adjustment while minimizing space usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the clamping member clamps to the clamping grooves through the ends of the clamping portions, then the structure is simple, but the ends tend to come loose from constant deformation due to long-term or repeated use
Solution Approach 1:
The coupling device is divided into multiple coupling units, each independently connecting two adjacent frames. This segmentation allows each coupling unit to bear the clamping load separately, distributing the stress and preventing concentrated deformation at single clamping points, thereby improving reliability while maintaining structural simplicity.
Solution Approach 2:
The coupling unit acts as an intermediary component between adjacent frames, providing a dedicated coupling mechanism that transfers and distributes clamping forces. This intermediary structure prevents direct stress concentration on the frame ends, reducing deformation and loosening over time.
2Reliability
If the clamping member is disposed between the lamp holder and the ceiling, then the connection is secure, but adjustment and handling by a user below the lamp holder are complicated
Solution Approach 1:
By segmenting the coupling mechanism into modular coupling units with exposed adjusting members on the side walls, the system allows users to access and adjust the connection from below the lamp holder, improving ease of operation while maintaining secure connection through the distributed coupling units.
Solution Approach 2:
Instead of positioning the adjustment mechanism above the lamp holder where it would be secure but inaccessible, the adjusting members are positioned on the side walls of the frames, allowing users to access them from below. This inverted positioning approach maintains connection security while dramatically improving user accessibility.
3Reliability
If multiple coupling units are used to interconnect frames, then the connection reliability is improved, but the device complexity increases
Solution Approach 1:
Each coupling unit is designed as a universal module that can be repeatedly used to connect any two adjacent frames in the series. This multi-functional design allows the same coupling unit structure to serve multiple connection points, improving overall connection reliability through redundancy while avoiding the need to design different components for different positions.
Solution Approach 2:
The coupling units are designed with homogeneous structures that are identical or similar across all connection points. This homogeneity simplifies manufacturing, assembly, and maintenance while providing consistent reliability across all frame connections. The uniform design reduces complexity by eliminating the need for varied component specifications.

AI summary
A coupling device includes a plurality of frames, each of which includes a base wall, and two spaced-apart side walls that cooperate with the base wall to define an accommodation space. The frames are arranged such that the accommodation spaces of the frames communicate with each other. At least one coupling unit is disposed in the accommodation spaces of two adjacent ones of the frames and applies a force to the side walls of the two adjacent ones of the frames so as to couple together the two adjacent ones of the frames.
