Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the terminal operates in normal power mode to maintain user experience, then performance and functionality are improved, but battery consumption increases reducing operational duration

Engineering Contradiction:
Improveuser convenienceVSAvoidbattery operational duration
Core Design Contradiction:
Ease of operationVSDuration of action of moving object

Solution Approach 1:

The terminal dynamically adjusts power consumption characteristics by switching between normal and power-saving modes based on predicted battery status. The controller monitors remaining battery capacity and automatically transitions operational modes to optimize the balance between user convenience and battery duration, making the system adaptive rather than static.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system performs preliminary prediction of battery depletion timing and proactively switches to power-saving mode before the battery is fully depleted. This advance action allows the terminal to prepare for low-power operation, maintaining user convenience as much as possible while extending the overall battery operational duration by preventing complete exhaustion.

Inventive Principle:
Principle #10Preliminary action

2Duration of action of moving object

If the terminal switches to power-saving mode to extend battery life, then battery operational duration is improved, but performance and user experience deteriorate

Engineering Contradiction:
Improvebattery operational durationVSAvoiduser convenience
Core Design Contradiction:
Duration of action of moving objectVSEase of operation

Solution Approach 1:

The terminal dynamically adjusts power consumption characteristics by switching between normal and power-saving modes based on predicted battery status. The controller monitors remaining battery capacity and automatically transitions operational modes to optimize the balance between user convenience and battery duration, making the system adaptive rather than static.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes operational parameters by adjusting power consumption levels based on predicted battery depletion timing. When battery depletion is predicted soon, the terminal modifies performance parameters to extend operational duration. When battery status is healthy, parameters are adjusted to maximize user convenience, creating a flexible parameter adaptation strategy.

Inventive Principle:
Principle #35Parameter changes

3Loss of information

If the terminal provides detailed battery status information to users, then information accuracy is improved, but system complexity increases

Engineering Contradiction:
Improvebattery status information accuracyVSAvoidpower management system complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The terminal implements a feedback mechanism where the controller continuously monitors battery status, predicts depletion timing, and communicates this information to the user. This closed-loop feedback system provides accurate battery status information while managing complexity through automated prediction algorithms rather than requiring complex manual tracking systems.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The power management system operates autonomously by automatically monitoring battery status, predicting depletion timing, and switching between operational modes without requiring complex user intervention. The system serves itself by managing power consumption based on its own monitored data, reducing the need for complex external control mechanisms.

Inventive Principle:
Principle #25Self-service
