Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If cam-based data is edited based on rotation angle, then the control command can be generated for rotational positioning, but the data cannot be edited based on elapsed time requiring laborious conversion processes
Solution Approach 1:
The control device is designed to accept and process both cam-based data (rotation angle) and time-based data (elapsed time) through the same input interface. The computation unit automatically identifies the data type and performs appropriate processing, eliminating the need for manual conversion between different data formats and enabling flexible editing regardless of the desired parameter basis.
Solution Approach 2:
The computation unit serves as an intermediary that automatically converts between cam-based and time-based data representations. When the user inputs data in one format and requests editing in another format, the computation unit performs the necessary mathematical conversion using the relationship between rotation angle and elapsed time, transparently providing the converted data without requiring user intervention in the conversion process.
2Ease of operation
If time-based data is edited based on elapsed time, then the control command can be generated for time-synchronized positioning, but the data cannot be edited based on amount of cam rotation requiring laborious conversion processes
Solution Approach 1:
The control device pre-establishes the relationship between cam-based data and time-based data by storing the correspondence between rotation angle and elapsed time. This preliminary setup allows the computation unit to instantly perform conversions in either direction without requiring real-time calculation or manual intervention, significantly reducing the time required for data editing and conversion.
3Adaptability or versatility
If conversion between cam-based and time-based data is performed manually using a computer, then the data can be converted, but the editing process becomes laborious and time-consuming
Solution Approach 1:
The input unit and computation unit are merged into an integrated system that simultaneously handles both cam-based and time-based data processing. The computation unit combines the functions of data reception, format identification, automatic conversion, and control command generation into a single unified process, eliminating the need for separate manual conversion steps and external computer operations.

AI summary
A control data generation device includes a computation unit calculating a control command based on rotational information or temporal information. The rotational information specifies a relationship between a specific rotation angle or specific rotational position during one spindle revolution and a position of the driven device. The temporal information specifies a relationship between a specific elapsed time during one spindle revolution and the position of the driven device. It also includes a display control unit controlling displaying the control command. Upon reception of an order to display temporal information during displaying rotational information, the rotational information is converted into the temporal information, and the obtained temporal information is displayed on the display device. Upon reception of an order to display rotational information during displaying temporal information, the computation unit converts the temporal information into the rotational information, and displays the rotational information obtained by the conversion.
