Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate safety lights are installed to provide emergency lighting, then emergency lighting function is achieved, but installation work and costs increase
Solution Approach 1:
The patent combines the emergency sign light and the safety light into a single integrated device. The housing contains both the first light-emitting diode module for illuminating the safety sign and the second light-emitting diode module for providing emergency lighting. This merging eliminates the need for separate safety lights, reducing installation work and costs while maintaining both functions.
Solution Approach 2:
The safety sign luminaire is designed to perform multiple functions: it displays the safety sign during normal operation and provides emergency lighting when needed. The housing and power supply unit support both the sign illumination function and the emergency lighting function, making the device universal and eliminating the need for additional separate safety lights.

This merging eliminates the need for separate safety lights, reducing installation work and costs while maintaining both functions.
3Ease of operation
If inductive energy transmission is used to power the second light-emitting diode module, then wireless power transfer is achieved, but energy transmission efficiency may be affected
Solution Approach 1:
The patent replaces the mechanical connection (wires) for power transmission with an inductive coupling system. The first conductor loop in the housing and the second conductor loop in the light-emitting diode module create a magnetic field that transfers energy wirelessly. This substitution simplifies the structure and enables easy attachment while maintaining sufficient energy transmission efficiency for the application.
