Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a fixed charging current is used to charge the battery, then the charging process is simple, but the charging time becomes unsatisfactory and cannot adapt to user needs

Engineering Contradiction:
Improvecharging process simplicityVSAvoidcharging time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The charging current is transformed from a fixed value to a dynamic value that changes based on historical usage data. The system calculates a predicted charging current by analyzing past working durations and correlating them with charging capacity, allowing the charging process to adapt automatically to user behavior patterns while maintaining operational simplicity

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system incorporates feedback mechanisms by continuously monitoring historical working durations and using this data to adjust the charging current. The predicted working duration derived from historical data feeds back into the charging control algorithm, creating a closed-loop system that optimizes charging time based on actual user usage patterns

Inventive Principle:
Principle #23Feedback

2Device complexity

If a fixed charging current is used, then the charging method is simple, but the battery may degrade prematurely even when not heavily used

Engineering Contradiction:
Improvecharging method complexityVSAvoidbattery lifespan
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The charging current parameter is dynamically adjusted based on historical usage data and predicted working duration. By changing the charging current from a fixed parameter to a variable parameter determined by actual usage patterns, the system prevents excessive current application that would accelerate battery degradation while maintaining simple charging hardware

Inventive Principle:
Principle #35Parameter changes

3Productivity

If historical data analysis is implemented to predict charging needs, then charging time is optimized and battery life is extended, but the system complexity increases

Engineering Contradiction:
Improvecharging efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system performs self-service by automatically collecting historical working duration data and using this data to determine the optimal charging current without requiring user intervention. The predicted working duration is calculated autonomously from historical patterns, and the charging process is automatically adjusted based on this prediction, reducing the need for complex user interfaces or manual configuration

Inventive Principle:
Principle #25Self-service

AI summary

A battery charging method is disclosed. The method includes: obtaining historical working durations in which the electronic device was powered by a battery of the electronic device; in response to an electronic device connected to a charging power source, obtaining a remaining battery level and a target capacity of a battery of the electronic device, and accordingly defining a capacity to be charged; obtaining a current system time when the electronic device is connected to the charging power source; obtaining a specific time difference between the current system time and a predicted working duration, wherein the predicted working duration is a specific working duration chosen from the historical working durations subsequent to the current system time; and using the capacity to be charged to correspond to the specific time difference to obtain a predicted charging current value.
