Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional coal-based storage batteries are used for emergency lighting and evacuation guidance, then the system can provide emergency power supply, but it consumes large amounts of non-renewable coal resources and causes environmental pollution
Solution Approach 1:
The patent changes the energy source parameter from non-renewable coal-based batteries to renewable energy sources (wind power, solar power). The system incorporates wind power generators and solar panels to generate electricity, fundamentally altering the energy parameter from polluting to environmentally friendly while maintaining emergency power supply capability
Solution Approach 2:
The patent creates a hybrid power system that copies and integrates multiple energy generation methods (wind power, solar power, and traditional battery backup) to replace the single coal-based battery system. This multi-source approach ensures reliability while eliminating the environmental harm of coal consumption
2Reliability
If a single energy source is used for emergency power supply, then the system structure is simple, but the power supply reliability during emergencies is insufficient
Solution Approach 1:
The patent merges multiple independent power generation systems (wind power generator, solar power panels, and battery backup) into a unified emergency power supply system. The controller integrates these different energy sources, managing their coordination to provide reliable power while organizing the complexity through centralized control
Solution Approach 2:
The emergency power supply system is designed with multi-functionality, capable of operating with multiple different energy sources (wind, solar, or battery backup). This universal design ensures that the system can adapt to different emergency scenarios and maintain reliability regardless of which energy source is available
3Object-affected harmful factors
If renewable energy sources like wind power and solar power are used, then environmental protection and emission reduction are achieved, but the system complexity increases
Solution Approach 1:
The patent segments the renewable energy system into independent, modular components: wind power generators, solar power panels, battery backup systems, and a central controller. Each component functions independently but can be easily integrated, reducing the perceived complexity through modularity while achieving environmental benefits

AI summary
An emergency lighting and evacuation guidance system includes an emergency lighting and evacuation guidance arrangement which is electrically connected to a commercial electricity supply, and a complementary green power assembly which is electrically connected to the emergency lighting and evacuation guidance arrangement. When the commercial electric supply is cut off during an emergency, the power generated by the complementary green power assembly is supplied to the emergency lighting and evacuation guidance arrangement, whereby the emergency lighting and evacuation guidance arrangement guides people to evacuate and escape during the emergency.
