Solution Overview
Problem
Current auxiliary power devices for mobile devices, such as cellular phones, often fail to extend battery life significantly due to inefficiencies in voltage boosting and current handling, leading to overheating and safety issues, and lack automatic control to optimize power usage.
Innovation Solution
A power supply system with a booster module and control unit that monitors and adjusts the source voltage and device voltage to ensure efficient power delivery to mobile devices, eliminating the need for manual switching and preventing overheating by automatically disabling the booster when not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual switching is used to control the booster, then the device complexity is reduced, but the ease of operation deteriorates and power usage optimization is lost
Solution Approach 1:
The control unit automatically detects when the mobile device is connected or disconnected and autonomously activates or deactivates the booster module without requiring manual user intervention. This self-service mechanism resolves the contradiction by providing automatic control (improving ease of operation) through an automated detection and control system (accepting increased device complexity).
2Power
If the booster module operates continuously, then the power delivery capability is maintained, but the temperature increases causing overheating and safety issues
Solution Approach 1:
The control unit continuously monitors the operational state of the booster module and automatically deactivates it when the mobile device is disconnected or when overheating conditions are detected. This feedback mechanism resolves the contradiction by maintaining power delivery capability when needed while preventing overheating through automatic shutdown based on real-time monitoring.
Solution Approach 2:
The system uses periodic monitoring and intermittent operation of the booster module rather than continuous operation. The booster is activated only during periods when power delivery is needed and deactivated during periods when it is not needed, preventing continuous heat generation while maintaining capability when required.
3Adaptability or versatility
If the booster module is always active, then the adaptability to different power needs is maintained, but the energy consumption increases
Solution Approach 1:
The system dynamically adjusts the operational state of the booster module based on real-time detection of mobile device connection status and power needs. Rather than static continuous operation, the booster transitions between active and inactive states dynamically, maintaining adaptability when needed while reducing energy consumption during idle periods.
