Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sensors and operation information are collected to estimate degradation cause, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent segments the degradation estimation process into distinct functional modules: degradation detection means that quantifies degradation amount, observation means that collects sensor data and operation information, section detection means that identifies degradation sections, and cause estimation means that determines degradation causes. This segmentation allows each module to perform a specific function, improving measurement precision while managing system complexity through modular design.
Solution Approach 2:
The observation means is designed to universally collect multiple types of data including sensor values from various sensors and operation information from different sources. This multi-functional observation system can adapt to different degradation scenarios by collecting relevant data from multiple sources, improving estimation accuracy without requiring separate specialized systems for each type of monitoring.
2Measurement precision
If degradation sections are precisely detected to identify causes, then measurement precision is improved, but loss of time increases
Solution Approach 1:
The patent performs preliminary detection of degradation sections by continuously monitoring and comparing degradation amounts against threshold values. By pre-identifying degradation sections before detailed cause analysis is required, the system prepares degradation section information in advance, reducing the time needed for subsequent cause estimation while maintaining precise identification of when and where degradation occurs.
Solution Approach 2:
The system implements feedback by continuously monitoring degradation amounts and using this information to refine degradation section detection. The degradation detection means provides ongoing feedback about degradation progression, allowing the section detection means to accurately identify degradation sections in real-time without requiring extensive post-processing analysis, thus balancing precision with time efficiency.
