Remote Power Reset Circuit for Dual-Battery Mobile Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems require manual intervention to reboot remote devices, leading to costly downtime and inefficiencies, especially in remote locations with intermittent power sources.
Innovation Solution
A single control unit with integrated power reset, switchover, and health monitoring capabilities, enabling remote power cycling and management of devices using a single circuit board, including a power switch-over circuit and charge controller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual intervention is used to reboot remote devices, then device reliability can be maintained through direct control, but operational costs increase and downtime extends due to the need for physical access to remote locations
Solution Approach 1:
The system enables self-service through automated power cycling capabilities. The power reset logic automatically reboots the processor and peripheral devices without requiring manual intervention, allowing the remote device to service itself during failures and reducing the need for human access to remote locations
Solution Approach 2:
The patent introduces a power management circuit board as an intermediary between the power source and the remote device components. This intermediary includes power reset logic that can autonomously cycle power to the processor and peripheral devices, enabling remote rebooting without physical access to the device location
2Device complexity
If a single integrated control unit is used, then device complexity is reduced and autonomy is enhanced, but the initial system design becomes more challenging
Solution Approach 1:
The patent merges multiple previously separate functions into a single integrated control unit. The power management circuit board combines power reset logic, power switch-over circuitry, charge controller, and health monitoring capabilities into one unified device, simplifying the overall system architecture and reducing the number of separate components required
Solution Approach 2:
The control unit is designed with multi-functionality to handle diverse power management tasks. It can reset the processor, control peripheral devices, manage battery charging, switch between power sources, and monitor system health - all within a single integrated unit that serves multiple functions previously requiring separate devices
