Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If generators are used to power emergency lighting during power outages, then emergency lighting is provided, but the system requires a lot of space, is expensive, and can be noisy
Solution Approach 1:
The patent combines the emergency lighting system with the EV charging station infrastructure. The lighting system shares the same housing, power supply circuitry, and control mechanisms as the EV charger, eliminating the need for separate generator equipment. The AC power supply and battery system serve dual purposes: charging EVs during normal operation and powering emergency lights during outages.
Solution Approach 2:
The EV charging station is designed with multi-functionality to serve as both an electric vehicle charger and an emergency lighting system. The housing contains both EV charging components and lighting components, allowing a single structure to fulfill multiple functions - charging vehicles during normal power conditions and providing emergency illumination when power is lost.

The AC power supply and battery system serve dual purposes: charging EVs during normal operation and powering emergency lights during outages.
Solution Approach 2:
The patent replaces the mechanical generator system with an electrical battery-based power system. Instead of using a mechanical generator to convert mechanical energy to electrical energy for emergency lighting, the system uses an already-charged battery to directly supply electrical energy to the lighting components, eliminating mechanical moving parts, noise, and associated maintenance costs.
3Loss of energy
If efficient stadium lighting systems are used with battery power sources, then electricity demand is reduced, but the infrastructure for electric vehicle charging is lacking
Solution Approach 1:
The EV charging station is designed with multi-functionality to serve as both an electric vehicle charger and an emergency lighting system. The housing contains both EV charging components and lighting components, allowing a single structure to fulfill multiple functions - charging vehicles during normal power conditions and providing emergency illumination when power is lost.
Solution Approach 2:
The system uses the battery charged during EV charging operations to power the emergency lighting system during outages. The excess charging capacity and battery storage serve the dual purpose of vehicle electrification and public safety lighting, making the infrastructure self-sufficient for both transportation and lighting needs.
