Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual battery switching operations are implemented in existing electronic systems, then users can switch between batteries, but the operations become complex and cause interruptions in power supply
Solution Approach 1:
The control circuit automatically monitors battery energy levels and performs battery switching without user intervention. The system detects when the auxiliary battery energy falls below the threshold and autonomously switches to the main battery, eliminating complex manual operations and preventing power interruptions.
Solution Approach 2:
The control circuit continuously monitors the energy level of the auxiliary battery through watt-hour meters and uses this feedback to determine when switching is necessary. This closed-loop monitoring ensures reliable automatic switching at the optimal moment to maintain power supply continuity.
2Reliability
If automatic battery switching is implemented, then power supply continuity is maintained, but device complexity increases due to control circuits and state detectors
Solution Approach 1:
The control circuit performs multiple functions: monitoring auxiliary battery energy levels, determining switching timing, and executing battery switching. This multi-functional approach consolidates what could be separate complex components into a single integrated unit, reducing overall device complexity while maintaining reliability.
Solution Approach 2:
The state detector and control circuit are integrated into a unified power management system. The watt-hour meters for measuring battery energy are combined with the control logic in a single coordinated subsystem, reducing the number of separate components and simplifying the overall device structure.
3Adaptability or versatility
If priority settings for multiple batteries are provided, then users can customize battery usage, but the operation becomes more complex requiring setting menus
Solution Approach 1:
The system is pre-configured with default priority settings where the auxiliary battery is used first and the main battery serves as backup. This preliminary configuration eliminates the need for users to manually set priorities in most cases, simplifying operation while maintaining adaptability through optional customization.
Solution Approach 2:
The control circuit automatically manages battery priority and switching based on pre-programmed logic and real-time energy level monitoring. Users benefit from adaptive battery management without needing to navigate complex setting menus, as the system self-adjusts based on battery states and usage patterns.

AI summary
In electronic device (102) of the present disclosure, control circuit (153) selects one of first battery (201) and second battery (202) of extension device (103), and causes selected one to supply electric power to a load circuit. Control circuit (153) detects which state of switch (171) is in a first state or a second state. Control circuit (153) preferentially selects first battery (201) as a supply source of electric power to the load circuit as compared with second battery (202) when switch (171) is in the first state.
