Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If pre-programmed battery characteristics from manufacturing are used, then device complexity is reduced and ease of manufacture is improved, but measurement precision and reliability of battery status information deteriorate over time due to battery deterioration and environmental changes

Engineering Contradiction:
Improveease of manufactureVSAvoidmeasurement precision
Core Design Contradiction:
Ease of manufactureVSMeasurement precision

Solution Approach 1:

The patent implements dynamic battery status monitoring by continuously measuring actual battery parameters (voltage, current, temperature) and comparing them against stored characteristic curves to calculate state of charge. This dynamic approach replaces static pre-programmed values with real-time calculations that adapt to battery deterioration and environmental changes, resolving the contradiction between manufacturing simplicity and measurement precision over time.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system incorporates feedback mechanisms where measured battery parameters are continuously fed back into the calculation algorithm. The microprocessor uses feedback from voltage, current, and temperature sensors to adjust state of charge calculations, compensating for battery aging and environmental variations. This feedback loop maintains measurement precision without requiring complex manufacturing processes.

Inventive Principle:
Principle #23Feedback

2Device complexity

If pre-programmed battery characteristics are used, then device complexity is reduced, but adaptability to different battery conditions and environments deteriorates

Engineering Contradiction:
Improvedevice complexityVSAvoidadaptability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The battery monitoring system performs self-service by automatically measuring its own operating parameters (voltage, current, temperature) and calculating its state of charge without external intervention. The microprocessor autonomously compares measured values against stored characteristic curves and adjusts calculations based on actual conditions, enabling the device to adapt to different battery conditions and environments while maintaining simple architecture.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system adapts to varying conditions by dynamically changing calculation parameters based on measured temperature, current load, and voltage levels. The characteristic curves stored in memory account for different temperature ranges and discharge rates, allowing the system to adjust its state of charge calculations according to actual operating parameters without increasing hardware complexity.

Inventive Principle:
Principle #35Parameter changes
