Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a built-in algorithm is used to predict residual use duration, then battery discharge control can be automated, but prediction accuracy is insufficient to meet user expectations

Engineering Contradiction:
Improveprediction accuracyVSAvoidcontrol strategy complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments the battery discharge control into multiple independent modules: scene mode identification module, power consumption information acquisition module, expected use duration acquisition module, and discharge control module. Each module handles a specific aspect of the control process, improving overall prediction accuracy while maintaining manageable system complexity through modular design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary actions by pre-acquiring power consumption information for different scene modes and pre-determining expected use duration before actual discharge control is needed. This allows the system to have prediction data ready in advance, improving real-time prediction accuracy without adding computational complexity during critical discharge decisions.

Inventive Principle:
Principle #10Preliminary action

2Use of energy by moving object

If battery discharge control is optimized for specific scene modes, then power consumption efficiency improves, but the system becomes less adaptable to varying user needs

Engineering Contradiction:
Improvepower consumption efficiencyVSAvoidflexibility to user expectations
Core Design Contradiction:
Use of energy by moving objectVSAdaptability or versatility

Solution Approach 1:

The patent implements a universal scene mode identification mechanism that can recognize and adapt to multiple different scene modes (gaming, video playback, music playback, browsing, etc.). The system maintains a library of power consumption information for various scenes and automatically selects the appropriate profile, achieving both specialized optimization for each mode and universal adaptability to user needs through a single flexible framework.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system dynamically adjusts discharge control strategies based on real-time scene mode identification and user-provided expected use duration. Rather than using fixed discharge rates, the system continuously adapts the discharge control to match current power consumption characteristics of the active scene mode and align with user expectations, achieving both efficiency and flexibility through dynamic adjustment.

Inventive Principle:
Principle #15Dynamics

3Measurement precision

If the system acquires detailed power consumption information for different scenes, then discharge control accuracy improves, but information processing complexity increases

Engineering Contradiction:
Improvedischarge control accuracyVSAvoidinformation processing complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system performs preliminary acquisition and storage of power consumption information for various scene modes before actual discharge control is needed. By pre-processing and organizing this data in advance, the system reduces real-time information processing complexity while maintaining high discharge control accuracy through ready-accessible, pre-validated power consumption profiles.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system automatically identifies scene modes and selects appropriate power consumption information without requiring manual user input or complex real-time analysis. The scene mode identification and information selection processes are self-service automated functions that reduce processing complexity by eliminating manual intervention while maintaining accurate discharge control through intelligent automated decision-making.

Inventive Principle:
Principle #25Self-service
