Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual operation and monitoring methods are used to verify actuator installation, then installation verification can be performed, but the process is time-consuming and prone to errors
Solution Approach 1:
The actuator performs self-verification by automatically monitoring its own temperature data and comparing it against expected performance criteria. The processing circuit within the actuator autonomously determines whether temperature data meets installation requirements and generates appropriate alarm signals, eliminating the need for manual verification operations.
Solution Approach 2:
The system implements automatic feedback by continuously monitoring temperature data from sensors and comparing it against pre-stored expected performance criteria. The processing circuit analyzes this feedback information and automatically generates alarm signals when installation deviations are detected, creating a closed-loop verification system that provides real-time installation status information.
2Ease of operation
If manual monitoring of temperature zones is performed, then installation correctness can be assessed, but the process is inefficient and difficult
Solution Approach 1:
The patent replaces manual mechanical monitoring operations with an automated electronic system. The processing circuit electronically compares temperature data against expected criteria and automatically generates alarm signals, substituting the manual mechanical process of monitoring and assessment with an automated electronic verification system that is both easier to operate and more efficient.
Solution Approach 2:
The actuator system performs self-verification by automatically monitoring its own temperature data and comparing it against expected performance criteria. The processing circuit within the actuator autonomously determines whether temperature data meets installation requirements and generates appropriate alarm signals, eliminating the need for manual verification operations.
3Reliability
If automatic temperature monitoring and analysis is implemented, then verification time is reduced and accuracy is improved, but device complexity increases
Solution Approach 1:
The processing circuit performs multiple functions: it monitors temperature data from sensors, compares the data against expected performance criteria, determines whether installation requirements are met, and generates alarm signals. By consolidating these multiple verification functions into a single integrated processing circuit, the system achieves high reliability without proportionally increasing overall device complexity.
Solution Approach 2:
The patent combines the temperature monitoring, data analysis, comparison against criteria, and alarm generation functions into an integrated processing circuit within the actuator. This merging of functions reduces the need for separate manual operations and external monitoring equipment, achieving automatic verification while managing system complexity through functional integration.
