Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed threshold value is used for abnormality determination, then the system is simple to operate, but it cannot accommodate varying user requirements and circumstances
Solution Approach 1:
The patent implements dynamic threshold values that can be adjusted by users based on their specific requirements and circumstances. The system allows users to modify the threshold used for determining whether a servo motor operation is abnormal, transforming the fixed parameter into a dynamic one that adapts to different operational contexts and user needs.
2Measurement precision
If a fixed threshold value is used for abnormality determination, then the system structure is simple, but the detection precision cannot be tailored to specific needs
Solution Approach 1:
The patent enables users to change the threshold parameter according to their specific detection needs. By allowing modification of the threshold value used for abnormality determination, the system achieves customizable detection precision while maintaining ease of operation through a user-friendly interface that accepts simple input parameters.

AI summary
An information processing method is implemented by an information processing device and involves: acquiring a command signal for driving the servo motor and measurement data measured with respect to the servo motor or to the control target device when the servo motor performs an operation on the basis of the command signal; calculating an abnormality degree of the operation of the servo motor on the basis of the command signal and the measurement data; displaying the measurement data and the abnormality degree on a display device; acquiring, from an input device, setting information of an allowable range which is variably set by a user operation on the basis of the displayed measurement data; setting the threshold value on the basis of the setting information; and further displaying the set threshold value on the display device in accordance with the abnormality degree.
