Solution Overview

Problem

Existing charging strategies for terminals, such as mobile phones, fail to effectively manage and control temperature rise, leading to inconsistent user experiences as they cannot meet individual user preferences for charging temperature rise.

Innovation Solution

A method and apparatus that detect the terminal's charging state and estimate a user-specific charging temperature rise sensitive threshold based on historical data, adjusting the charging temperature rise to meet user expectations by updating the charging strategy, including maximum temperature thresholds, charging power, and working modes of charging channels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If charging power is increased to improve charging performance, then charging speed is improved, but temperature rise increases

Engineering Contradiction:
Improvecharging speedVSAvoidcharging temperature rise
Core Design Contradiction:
ProductivityVSTemperature

Solution Approach 1:

The charging strategy dynamically adjusts charging power based on real-time temperature monitoring and user sensitivity thresholds. The system transitions from static charging power to dynamic adjustment, modifying charging parameters during the charging process to maintain optimal temperature while preserving charging speed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes charging parameters (power, current, voltage) based on temperature conditions and user preferences. By adjusting these parameters dynamically according to temperature rise and user sensitivity thresholds, the system resolves the contradiction between fast charging and temperature control.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If general charging temperature control is applied, then charging safety is improved, but individual user temperature preferences cannot be met

Engineering Contradiction:
Improvecharging safetyVSAvoiduser preference adaptation
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system implements feedback mechanisms by monitoring user actions during charging (such as device usage patterns, heat sensitivity responses) and using this feedback to learn and adapt to individual user temperature preferences. This enables personalized charging strategies that satisfy both safety requirements and individual user expectations.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system automatically learns and adapts to user preferences without requiring explicit user input or configuration. Through self-learning from charging behavior data, the system autonomously adjusts charging strategies to match individual user temperature sensitivities, eliminating the need for manual setup while providing personalized service.

Inventive Principle:
Principle #25Self-service
