Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If power consumption is limited to secure operating time, then battery life is extended, but device performance and functionality are degraded
Solution Approach 1:
The system dynamically adjusts the power consumption of individual electronic circuits based on real-time battery capacity information and user-specified target operating times. The controller continuously monitors battery status and modifies circuit power consumption levels, transitioning from static power management to dynamic adaptation, thereby resolving the contradiction between extending operating time and maintaining device performance.
Solution Approach 2:
The system changes the power consumption parameter of electronic circuits based on battery capacity and target time requirements. By adjusting power consumption parameters dynamically rather than using fixed settings, the system can extend operating time while preserving necessary device performance, directly addressing the technical contradiction.
2Duration of action of moving object
If power consumption is reduced to extend battery life, then operating time increases, but user convenience and device usability deteriorate
Solution Approach 1:
The system implements feedback by continuously monitoring battery capacity information and using it to adjust power consumption of electronic circuits. This closed-loop control ensures that operating time is extended without excessively compromising usability, as the system adapts based on actual battery status rather than applying fixed power reduction, thus resolving the contradiction between operating time and user convenience.
Solution Approach 2:
The system dynamically adjusts power consumption based on real-time battery status and user requirements, allowing flexible adaptation between performance and battery life. This dynamic approach maintains ease of operation while extending operating time, unlike static power saving modes that permanently degrade usability.
3Use of energy by stationary object
If conventional power saving modes are used, then power consumption is limited, but precise control over target operating time is not achievable
Solution Approach 1:
The system changes power consumption parameters of individual electronic circuits based on calculated requirements for achieving specific target operating times. By adjusting power consumption as a variable parameter rather than using fixed saving modes, the system achieves precise control over operating time while maintaining adaptability to different user needs and battery conditions.
Solution Approach 2:
The system segments power management control by individually adjusting power consumption of specific electronic circuits rather than applying uniform power saving modes to the entire device. This granular approach enables precise control over total power consumption to achieve target operating times while maintaining adaptability and flexibility in meeting diverse user requirements.

AI summary
Provided are an electronic apparatus and control method that can secure a target operating time. An electronic apparatus includes: a battery; two or more electronic circuits that operate with power supplied from the battery; and a controller. The controller acquires power information indicating power consumption of each of the two or more electronic circuits, acquires capacity information indicating remaining capacity of the battery, receives time information indicating a target time for which the two or more electronic circuits are to operate, and adjusts the power consumption of each of the two or more electronic circuits based on the power information and the capacity information so that the two or more electronic circuits will operate for the target time or longer.
