Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If power consumption is limited by setting a power saving mode, then power consumption is reduced, but the ability to adjust power consumption to secure a desired operating time is lost
Solution Approach 1:
The patent segments the power consumption control by dividing the electronic circuits into multiple groups and individually managing power consumption for each group. This allows selective adjustment of power consumption in specific circuits while maintaining others, providing both power reduction and flexible adaptability to meet desired operating times.
Solution Approach 2:
The patent implements dynamic power consumption adjustment by continuously monitoring battery capacity and operating time requirements, then dynamically changing the power consumption level of electronic circuits accordingly. This enables the system to adapt power consumption in real-time rather than being fixed in a power saving mode.
2Duration of action of moving object
If power consumption is reduced to extend operating time, then battery life is extended, but the operating time may still not meet the user's target time requirement
Solution Approach 1:
The patent employs feedback control by monitoring the actual operating time and comparing it with the user's target operating time. Based on this feedback, the system automatically adjusts the power consumption level of electronic circuits to ensure the target operating time is achieved, preventing both over-reduction and excessive consumption.
Solution Approach 2:
The patent changes the power consumption parameter of electronic circuits based on calculated requirements. By computing the necessary power consumption level from battery capacity and target operating time, the system adjusts circuit parameters to precisely meet the desired operating duration.
3Ease of operation
If individual power consumption adjustment is implemented for each electronic circuit, then precise control over operating time is achieved, but system complexity increases
Solution Approach 1:
The patent implements a universal power management controller that handles multiple electronic circuits through a single integrated system. This multi-functional controller manages power distribution, monitoring, and adjustment across all circuits, reducing the need for separate control mechanisms for each circuit and thereby limiting complexity growth.
Solution Approach 2:
The patent uses parameter-based control where a central controller adjusts power consumption parameters of different circuits based on unified calculations. This approach maintains simplicity by using a single control logic that modifies circuit parameters rather than implementing complex individual control systems for each circuit.

AI summary
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.
