Remote Controller Circuit for Battery Switchover and Device Reset
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems require manual intervention to reset remote devices, leading to costly downtime and inefficiencies, especially in scenarios where power sources are intermittent or remote from centralized locations.
Innovation Solution
A single control unit on a circuit board integrates power reset, switchover, and health monitoring functions, enabling remote power cycling and management of devices, including switching between primary and secondary batteries, and limiting current to extend autonomy and reduce power consumption.

Engineering Contradiction Analysis
1Reliability
If manual intervention is used to reset remote devices, then device functionality can be restored, but downtime and operational costs increase
Solution Approach 1:
The system enables self-service reset functionality where the remote device can automatically reset itself or be remotely reset without requiring physical manual intervention. The controller monitors device status and can trigger reset sequences automatically when failure conditions are detected, eliminating the need for operators to travel to remote locations.
Solution Approach 2:
A communication interface or network connection acts as an intermediary between the operator and the remote device, allowing reset commands to be transmitted electronically. This mediator enables remote device control without physical presence, reducing downtime by allowing instant reset initiation from a distance.
2Device complexity
If a single control unit integrates multiple functions, then device complexity is reduced, but the control unit must handle more diverse operations
Solution Approach 1:
Multiple control functions (reset control, power management, health monitoring) are merged into a single integrated control unit on the circuit board. This consolidation reduces the number of separate components and simplifies the overall system architecture while maintaining all necessary functionalities through unified control logic.
Solution Approach 2:
The single control unit is designed with universal capabilities to perform diverse operations including device reset, battery management, and system health monitoring. This multi-functional design allows one component to replace multiple specialized components, reducing complexity while expanding adaptability.
3Duration of action of moving object
If current is limited to extend battery autonomy, then power consumption is reduced, but available power for operations decreases
Solution Approach 1:
The system dynamically adjusts current limits based on operational requirements and battery status. Rather than using a fixed current restriction, the control unit can vary current delivery in real-time, allowing higher power when needed for critical operations and lower current during normal operation to extend autonomy, thus balancing both requirements.
Solution Approach 2:
The system changes operational parameters such as current draw and power consumption levels based on battery charge state and mission requirements. By adjusting these parameters dynamically, the system can extend battery life during non-critical phases while ensuring sufficient power is available when required for essential functions.
