Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If continuous data acquisition of operating parameters is implemented, then complete operating data is available for analysis, but significant storage capacity is required which is neither available nor feasible in fan hardware
Solution Approach 1:
The patent extracts only the essential information from continuous operating parameter data by detecting state change events. Instead of storing all raw data, the system identifies and stores only those moments when the basic parameter transitions between states, thereby obtaining necessary operating information while dramatically reducing storage requirements.
Solution Approach 2:
The patent applies parameter changes by transitioning from continuous parameter monitoring to discrete state change detection. The basic parameter is divided into multiple states, and the system monitors transitions between these states rather than continuously recording the parameter values, thus reducing data volume while preserving critical operational information.
2Loss of information
If a gateway is integrated into the motor system to forward collected operating parameter data to a central evaluation unit, then data transmission is enabled, but the system becomes cumbersome and requires a permanent connection to central computing units
Solution Approach 1:
The patent removes the need for a continuous gateway connection by extracting and storing critical state change events locally in the motor system's memory. This eliminates the requirement for permanent gateway connections to central computing units, simplifying the system architecture while ensuring operating data is preserved for later analysis.
3Quantity of substance
If the basic parameter is divided into multiple states and state change events are detected, then the amount of data to be stored is reduced, but the complexity of detecting and measuring state changes increases
Solution Approach 1:
The patent applies preliminary action by pre-defining the states of the basic parameter before operation. The division into states and the criteria for state changes are established in advance, which simplifies the detection process during actual operation. The control device is pre-configured with state thresholds and transition rules, making the detection of state change events more straightforward.

AI summary
A method for capturing operating parameter data for a motor system having an electric motor, wherein states of operating parameters are captured during operation of the motor system, wherein the operating parameters comprise a basic parameter and at least one additional parameter, wherein, based on a capture of the state of the basic parameter, state change events for the basic parameter are ascertained, wherein detection of a state change event for the basic parameter results in a state of the additional parameter being captured, and wherein the captured state of the additional parameter is stored in combination with the detected state change event. In addition, a corresponding motor system and a fan are specified.
