Solution Overview
Problem
In existing secure electrical power supply systems, the secondary power source, typically an inverter with a battery, discharges unnecessarily when the electrical load is not consuming energy, reducing its availability for subsequent power interruptions.
Innovation Solution
A control device with an emitter and receiver system, utilizing wireless communication, including a radiofrequency emitter and a processing unit, to monitor the state of the control unit and manage the secondary power source's activation and deactivation, preventing self-discharge by only engaging the secondary power source when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the secondary electrical power supply source remains connected to the power supply circuit during main power supply operation, then it is ready to provide backup power immediately, but the battery discharges by self-consumption reducing its availability
Solution Approach 1:
The control device is activated in advance to monitor the state of the control unit and predict when the secondary power supply will be needed. By detecting changes in the control unit state before the main power supply fails, the system prepares to activate the secondary power supply only when necessary, preventing premature battery discharge while ensuring immediate backup capability when required.
Solution Approach 2:
The control device continuously monitors the state of the control unit and receives feedback about its changes. This feedback mechanism allows the system to adjust the activation state of the secondary power supply in real-time based on actual system conditions, ensuring the battery remains active only when the load is actually consuming energy, thereby preventing self-discharge while maintaining reliability.
2Reliability
If the secondary electrical power supply source is activated continuously, then battery energy is available when needed, but energy is wasted when the load is not consuming power
Solution Approach 1:
The system dynamically adjusts the activation state of the secondary power supply based on real-time conditions. The control device detects changes in the control unit state and accordingly activates or deactivates the secondary power supply, making it dynamic rather than static. This allows the battery to be active only when the load is actually consuming energy, optimizing energy usage while maintaining power supply reliability when needed.
