Power Supply Control Device for Battery Discharge Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems with remote control devices associated with computers, such as those in vehicles, face battery discharge issues when not in use, leading to inability to control functions and restart systems due to continuous power supply consumption, especially in devices with limited storage capacities like motorcycles.
Innovation Solution
A control device with interrupting means is installed in the power supply circuit, allowing users to completely interrupt power to the computer when the system is put out of operation, preventing battery discharge, and optionally allowing for delayed reactivation or automatic state changes based on user commands or inactivity thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the computer is continuously supplied with power to enable remote control functions, then the system can respond to remote commands at any time, but the battery becomes completely discharged after prolonged inactivity
Solution Approach 1:
The control device is configured to receive a disable command from the user and proactively interrupt the power supply to the computer before complete battery discharge occurs. This preliminary action of cutting power upon receiving a disable command prevents the harmful effect of battery exhaustion while maintaining the ability to restore functionality when needed.
Solution Approach 2:
The power supply state is made dynamic rather than static. The system can switch between powered and power-interrupted states based on user commands and system conditions. The control device dynamically adjusts the power supply circuit state (connected or disconnected) according to operational needs, allowing the system to adapt between maintaining remote control capability and conserving battery energy.
2Duration of action of stationary object
If the battery capacity is increased to prevent discharge during inactivity, then the system can maintain power supply longer, but the device becomes heavier and more complex
Solution Approach 1:
The harmful element of continuous power consumption is extracted from the system by introducing an interrupting mechanism. The control device separates the power supply circuit into a connected state (when functionality is needed) and a disconnected state (when the system is disabled), removing the continuous drain that would otherwise require larger battery capacity to compensate for.
3Loss of energy
If the power supply is completely interrupted to conserve battery, then battery charge is preserved, but the system cannot be restarted or respond to commands
Solution Approach 1:
The control device monitors system state and user commands, providing feedback control of the power supply circuit. When a disable command is received, it interrupts power to conserve battery. When a restart or enable command is received, it restores power connection. This feedback mechanism ensures the system responds appropriately to user intentions while managing battery charge effectively.
