Solution Overview
Problem
Existing emergency supply systems for building technical devices, particularly lighting systems, lack reliable detection of emergency states and fail to maintain consistent operation during power failures, leading to inadequate voltage supply and potential device malfunction.
Innovation Solution
An emergency operating arrangement comprising a power supply unit and an emergency supply unit that detects changes in electrical supply, outputs a higher DC voltage during emergencies, and includes a detection circuit, charging circuit, output converter, control unit, and communication module to ensure continuous operation of connected devices by switching between power supply units and an emergency energy source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the emergency supply unit outputs a higher DC voltage during emergencies, then the power supply reliability is improved, but the device complexity increases due to additional detection circuits and voltage conversion components
Solution Approach 1:
The power supply system is divided into two independent units: a main power supply unit for normal operation and an emergency supply unit for emergency situations. Each unit has its own voltage output stage, allowing the emergency unit to independently provide higher voltage without affecting the main unit's simplicity.
Solution Approach 2:
The emergency supply unit includes a battery that is pre-charged during normal operation through a charging circuit. When emergency is detected, the pre-charged battery immediately provides the higher DC voltage without requiring real-time charging, ensuring rapid response while keeping the emergency path simple.
2Measurement precision
If the detection circuit continuously monitors the electrical supply to detect emergencies, then the detection reliability is improved, but the energy consumption increases
Solution Approach 1:
The detection circuit monitors the electrical supply voltage periodically rather than continuously. The control unit checks the supply voltage at regular intervals and triggers the emergency supply unit only when a voltage anomaly is detected, reducing energy consumption while maintaining reliable detection through systematic monitoring.
3Duration of action of moving object
If the charging circuit charges the battery at high power to ensure sufficient energy storage, then the duration of emergency operation is improved, but the loss of energy during charging increases
Solution Approach 1:
The charging circuit provides sufficient charging power to ensure the battery reaches full capacity for adequate emergency operation duration, but the system accepts some energy loss during charging as necessary to maintain the battery charged state. The benefit of having sufficient energy stored outweighs the charging losses.
