Power Connector Cold Reboot via Bridging Circuit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices often require a cold reboot for firmware updates, which is challenging when they are located remotely or hard to access, as warm reboots are insufficient for updating firmware effectively.
Innovation Solution
A power connector with a power input port, signal transmission port, controller, and bridging circuit that temporarily stops power supply to the external device upon receiving an indication signal, enabling a controlled cold reboot by selectively transferring input power through the bridging circuit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If warm reboot is used for software updating, then the updating process is simple and can be performed remotely, but the firmware updating cannot become effective
Solution Approach 1:
The power connector automatically detects when firmware updating is complete and autonomously performs the cold reboot by切断 power supply, eliminating the need for operator intervention. The system serves itself by monitoring its own state and executing the necessary power cycle to make firmware updates effective.
Solution Approach 2:
The power connector acts as an intermediary between the external power source and the electronic device. It controls the power flow to the device, enabling it to perform cold reboots by interrupting and restoring power supply, thus facilitating effective firmware updates without requiring physical access to the device.
2Reliability
If cold reboot is performed by manually cutting power supply, then the firmware updating becomes effective, but operator presence is required which is not feasible for remote devices
Solution Approach 1:
The power connector autonomously monitors the updating status of the electronic device and automatically executes the cold reboot sequence by controlling power supply interruption and restoration, without requiring any operator presence or manual intervention.
Solution Approach 2:
The power connector receives feedback signals from the electronic device indicating the completion of firmware updating. Based on this feedback, the controller automatically initiates the cold reboot process by adjusting the power supply state, creating a closed-loop control system that responds to device status changes.
3Duration of action of stationary object
If continuous power supply is maintained, then the electronic device operates continuously, but firmware updates cannot take effect without manual intervention
Solution Approach 1:
The power connector implements periodic control of power supply by temporarily interrupting it for a specific duration after firmware updating completion. This periodic power interruption enables the cold reboot necessary for firmware updates to take effect, while maintaining continuous operation during normal functioning periods.
Solution Approach 2:
The power connector dynamically adjusts its power supply state based on the operational phase of the electronic device. During normal operation, power is supplied continuously; upon detecting firmware update completion, the system dynamically transitions to a power interruption state to enable reboot, then returns to continuous supply mode.
Data Source
AI summary
A power connector has a power input port, a power output port, a signal transmission port, a controller, and a bridging circuit. The power input port is configured to receive input power. The power output port is applicable for plugging into an external device so as to provide output power to the external device. The signal transmission port is applicable for plugging into the external device to receive an indication signal. The controller is electrically connected to the signal transmission port and configured to adjust a control signal based on the indication signal. The bridging circuit is respectively electrically connected to the power input port, the power output port, and the controller, and controlled by the control signal to selectively transfer part of the input power to the power output port as the output power.
