Vehicle Exterior Power Supply for Authenticated Device Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable electronic devices experience rapid power consumption when simultaneously controlling utility device functions and device-centric functions, leading to untimely battery discharge, especially with increasing screen size.
Innovation Solution
A controlled power supply system that authenticates electronic devices based on pre-stored information and provides power only when the device is authenticated, using an external power supply unit coupled to the vehicle's exterior, ensuring efficient power management and extended battery life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If portable electronic devices simultaneously perform utility device functions and device-centric functions, then the functionality and control capability are improved, but the power consumption increases rapidly
Solution Approach 1:
The patent extracts the power supply function from the portable electronic device's internal battery by providing an external power supply through the vehicle's power outlet. This separates the device-centric functions (handled by the portable device) from the utility device functions (handled by the vehicle system), allowing the portable device to operate without consuming its own battery power while maintaining full functionality.
2Area of moving object
If the screen size of portable electronic devices is increased, then the user interface and display quality are improved, but the power consumption increases
Solution Approach 1:
The patent removes the power consumption burden from the portable electronic device by extracting it from the vehicle's power supply system. This allows the device to maintain a large screen size and high-quality display without the constraint of limited battery power, as the external power supply assumes the energy load.
3Duration of action of stationary object
If power is continuously supplied to the electronic device, then the device can operate without interruption, but unnecessary power consumption occurs when the device is not authenticated
Solution Approach 1:
The patent implements authentication as a preliminary action before power supply. The system checks whether the portable electronic device is authenticated (e.g., through biometric verification or authorized device recognition) before enabling power delivery. This ensures that power is only consumed by authorized devices, preventing energy waste while allowing continuous operation for authenticated users.
Solution Approach 2:
The system continuously monitors the authentication status of the portable electronic device and provides feedback by adjusting the power supply state accordingly. When the device is authenticated, power is supplied; when unauthenticated, power supply is interrupted. This feedback mechanism prevents unnecessary power consumption while maintaining continuous operation for authorized devices.
