Modular Trunk Fixture With Flexible Window For Safe Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing line illumination systems with elongated trunk fixtures are difficult to assemble and disassemble without risking damage to the fixture housing and cover, due to high manufacturing tolerances and click-snap connections.
Innovation Solution
A novel, modular design for elongated trunk fixtures featuring a fixture housing composed of a flexible synthetic material, with releasable connections between the fixture base plate, wall plates, and light exit window, allowing for easy assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If click-snap connection is used to connect fixture housing and fixture cover, then connection strength is improved, but ease of operation deteriorates due to difficulty in assembly and disassembly
Solution Approach 1:
The fixture is divided into modular components (fixture base plate, fixture wall plates, light exit window) that can be independently assembled and disassembled. Each component features standardized connection interfaces with thickened parts and slots that enable tool-free assembly while maintaining structural integrity during operation.
2Reliability
If high manufacturing tolerances are required for click-snap connection, then connection reliability is improved, but manufacturing precision cost increases
Solution Approach 1:
The light exit window is made from flexible synthetic material that can deform during assembly to engage with the thickened parts of the wall plates. This flexibility compensates for variations in manufacturing tolerances while ensuring reliable connection during normal operation.
Solution Approach 2:
The connection interface uses a thickened part fitting into a slot geometry that provides mechanical tolerance compensation. The flexible material parameter allows the light exit window to adapt to dimensional variations in the rigid fixture components, maintaining connection reliability across a range of manufacturing tolerances.
3Reliability
If additional suspension cables are added for safety, then safety is improved, but device complexity increases
Solution Approach 1:
The modular connection design with thickened parts and slots is预先 designed to provide inherent mechanical retention and safety during assembly and disassembly operations. This preliminary structural consideration eliminates the need for additional suspension cables, as the connection interface itself provides sufficient safety for maintenance operations.
