Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If indirect methods are used to determine load on rotating system components, then device complexity is reduced, but measurement precision and reliability deteriorate due to noise sensitivity
Solution Approach 1:
The patent replaces indirect mechanical/inferential load determination methods with direct physical measurement using sensor probes. The sensor probes physically contact the rotating component to directly measure displacement and strain, substituting complex indirect calculation methods with straightforward physical sensing, thereby improving measurement precision without significantly increasing overall system complexity.
Solution Approach 2:
The patent introduces sensor probes as intermediary devices between the rotating component and the measurement system. These probes act as mediators that directly sense physical quantities (displacement, strain) on the rotating component and transmit this information to the evaluation system, enabling direct load determination while isolating the complex measurement challenges to the probe level rather than the entire system.
2Measurement precision
If sensor probes directly measure displacement and strain on rotating components, then measurement precision improves, but device complexity increases due to additional sensing and signal processing requirements
Solution Approach 1:
The patent divides the measurement system into distinct functional segments: sensor probes for physical measurement, signal transmission components for data transfer, and evaluation components for analysis. This segmentation allows each component to be optimized independently and simplifies the overall system architecture by clearly defining interfaces and responsibilities between segments.
Solution Approach 2:
The sensor probes are designed to perform multiple measurement functions (displacement and strain measurement) simultaneously, reducing the need for separate sensing devices. The evaluation component also handles multiple tasks including signal processing, spectrum determination, and load estimation, making the system more efficient without proportionally increasing complexity.
3Reliability
If spectrum determination is performed from measured sensor signals, then reliability of load estimation improves, but loss of time increases due to signal processing requirements
Solution Approach 1:
The patent performs preliminary signal processing operations directly at the measurement stage, preparing the sensor signals for subsequent spectrum determination. By pre-processing the signals (filtering, conditioning) before they reach the evaluation component, the system reduces the computational burden later and enables faster, more reliable load estimation without significant time loss.
Solution Approach 2:
The patent implements continuous measurement and continuous signal processing, where sensor probes continuously monitor the rotating component and the evaluation component continuously processes the signals. This eliminates idle time between measurements and maintains uninterrupted data flow, ensuring that load estimation is always current without significant processing delays.
