Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If remaining use duration is predicted based on discharge current, then prediction can be obtained, but accuracy is low due to varying power consumption

Engineering Contradiction:
Improveprediction accuracyVSAvoidpower consumption monitoring
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent changes the prediction parameter from discharge current to power consumption. By monitoring actual power consumption values and comparing them with standard values, the system achieves more accurate remaining use duration predictions while adapting to varying usage conditions without requiring overly complex monitoring infrastructure

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system uses the device's own power consumption data to predict its remaining use duration. By continuously monitoring actual power consumption and comparing it with standard consumption patterns, the device self-evaluates its battery status and provides accurate predictions without external intervention

Inventive Principle:
Principle #25Self-service

2Duration of action of moving object

If power consumption is adjusted to extend remaining use duration, then user experience improves, but device may not maintain normal operation performance

Engineering Contradiction:
Improveremaining use durationVSAvoidnormal operation
Core Design Contradiction:
Duration of action of moving objectVSReliability

Solution Approach 1:

The patent dynamically adjusts power consumption based on user needs and battery status. The system can switch between different power consumption modes (standard mode for normal operation, energy-saving mode for extended duration) allowing flexible adaptation between performance and battery life requirements

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes power consumption parameters adaptively. By adjusting power consumption within certain ranges rather than fixed values, the device can extend remaining use duration while maintaining acceptable operation performance, resolving the contradiction between duration and reliability

Inventive Principle:
Principle #35Parameter changes

AI summary

Provided are a method and an apparatus for predicting a remaining use duration, an electronic device and a storage medium, which relates to a field of information processing technologies. The method includes: determining a current remaining energy of a battery based on state information of the battery in a current use scene; determining a current total power consumption of the electronic device in the current use scene; predicting the remaining use duration based on the current remaining energy and the current total power consumption; and displaying the remaining use duration through a display icon. The invention improves the accuracy of determining the remaining use duration and avoids the situation that the accuracy of determining the remaining use duration is reduced due to a changed discharge current when the remaining use duration is determined based on a discharge current.
