Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If preset conditions are applied uniformly for all users, then the device operation is simplified, but the measurement precision of energy consumption is deteriorated

Engineering Contradiction:

Improvedevice operationVSAvoidenergy consumption calculation

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The system performs preliminary action by having users register their individual body movement characteristics (walking style, running style, etc.) before actual energy consumption measurement. This pre-registration of personal data enables subsequent accurate energy calculation without requiring complex real-time adjustments, thus maintaining ease of operation while improving measurement precision.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The invention applies local quality by transitioning from uniform preset conditions for all users to user-specific customized conditions. Each user's body movement data is individually registered and stored, allowing the system to apply localized (personalized) detection thresholds and parameters matched to each user's unique characteristics, thereby improving energy consumption measurement accuracy.

Inventive Principle:

Principle #3Local quality

2Measurement precision

If individual user characteristics are taken into consideration, then the measurement precision of energy consumption is improved, but the device complexity is increased

Engineering Contradiction:

Improveenergy consumption calculationVSAvoiddata processing system

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The system uses copying by creating a reference model of each user's body movement characteristics through initial registration. Instead of implementing complex real-time analysis of unique user patterns, the system captures representative movement data during registration and stores it as reference templates. During actual measurement, the system compares current movements against these copied reference patterns, significantly reducing processing complexity while maintaining high measurement precision.

Inventive Principle:

Principle #26Copying

3Productivity

If body movement detection is performed always under certain conditions, then the productivity of the device is improved, but the measurement precision for individual users is deteriorated

Engineering Contradiction:

Improvedetection speedVSAvoidindividual user characteristics

Core Design Contradiction:

ProductivityVSMeasurement precision

Solution Approach 1:

The system performs preliminary action by pre-registering each user's individual body movement characteristics (walking style, running style, activity types) before actual energy consumption measurement. This creates a personalized reference database that enables the device to quickly and accurately identify and measure individual user activities without requiring complex real-time analysis, thus maintaining both high productivity and precision.
