Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional linear luminaires constructed from modules are complicated and prone to errors during assembly, with limitations on the number of lamp modules per control gear and requiring manual connection of forward and return lines, leading to inefficient and error-prone installation.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual connection of forward and return lines is required, then assembly precision can be controlled, but assembly complexity and error rate increase
Solution Approach 1:
The lighting module automatically detects whether it is connected to another module or not, and autonomously closes the switch device to connect the forward line to the return line without manual intervention. This self-assembly mechanism eliminates manual wiring while maintaining precise electrical connections through automated detection and switching.
2Area of stationary object
If the number of lamp modules per control gear is increased, then lighting coverage is improved, but system reliability decreases due to overloading
Solution Approach 1:
The current flow detection device continuously monitors the electrical connection status and provides feedback to the control device. When the detection device identifies that a lighting module is not properly connected or is overloaded, it triggers the control device to open the switch device, thereby disconnecting the module and preventing system failure while maintaining overall lighting coverage.
3Reliability
If automatic current flow detection is implemented, then assembly errors are reduced, but device complexity increases
Solution Approach 1:
The patent introduces a switch device as an intermediary component that mediates between the forward line and return line. This simple switching mechanism, controlled by the current flow detection device, achieves reliable automatic connection without requiring complex detection systems. The switch device acts as a mediator that simplifies the overall system while maintaining high assembly reliability.
