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

VSEngineering 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

Engineering Contradiction:
Improveconnection precisionVSAvoidassembly complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

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.

Inventive Principle:
Principle #25Self-service

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

Engineering Contradiction:
Improvelighting coverageVSAvoidsystem reliability
Core Design Contradiction:
Area of stationary objectVSReliability

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.

Inventive Principle:
Principle #23Feedback

3Reliability

If automatic current flow detection is implemented, then assembly errors are reduced, but device complexity increases

Engineering Contradiction:
Improveassembly reliabilityVSAvoiddetection system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

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.

Inventive Principle:
Principle #24Intermediary (Mediator)
