Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional benchmark human body parameter measurement method is used, then the measurement process is simple, but the accuracy of obtaining reference body parameter is low
Solution Approach 1:
The patent segments the measurement process into multiple independent modules: facial image acquisition module, green signal extraction module, heartbeat wave peak detection module, emotion analysis module, and posture analysis module. Each module processes specific aspects separately, improving measurement accuracy while maintaining manageable system complexity through modular design.
Solution Approach 2:
The patent merges multiple measurement dimensions (facial colorimetric data, emotion recognition, posture analysis) into a comprehensive human body parameter measurement system. By combining these different data sources and analyzing them together, the system achieves higher measurement accuracy than traditional single-method approaches.
2Measurement precision
If only benchmark human body parameter is used without considering emotion and posture, then the measurement system is simple, but the accuracy of safe interval determination is low
Solution Approach 1:
The patent introduces emotion and posture as additional parameters that affect human body parameter measurement. By incorporating these parameters into the analysis model and adjusting the measurement approach based on emotional state and posture conditions, the system achieves more accurate safe interval determination.
Solution Approach 2:
The patent uses facial images as an intermediary to connect emotion analysis with human body parameter measurement. The facial colorimetric data serves as a mediator that links emotional state to physiological parameters, enabling more accurate measurement without requiring direct emotional assessment.
