Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If graph display of operation performance is used, then visual recognition of condition changes is improved, but ease of identifying causative program steps deteriorates
Solution Approach 1:
The patent segments the machining program into individual blocks and associates each block with corresponding signal information. This segmentation allows operators to divide the complex program into manageable units, making it easier to identify which specific block causes abnormal conditions while maintaining visual graph display capabilities.
Solution Approach 2:
The patent introduces an intermediate data structure that links program blocks with signal information through time-axis association. This intermediary layer enables operators to trace back from visual signal abnormalities to specific program blocks without directly examining the entire program, thus facilitating easier identification of causative steps.
2Device complexity
If separate display of machining program and signal information is used, then device complexity is reduced, but loss of information increases
Solution Approach 1:
The patent merges machining program information and signal information into a single integrated display structure. By combining these previously separate data streams and presenting them together with temporal alignment, the system preserves the relevance relationship between program execution and signal generation without significantly increasing device complexity.
Solution Approach 2:
The patent adds a temporal dimension to the display by associating program blocks with signal information through time-axis positioning. This dimensional transformation allows the system to maintain separate data structures while visually integrating them in a way that preserves their relational context without requiring complex interconnections.
3Measurement precision
If detailed machining program information is displayed, then measurement precision of program impact is improved, but ease of operation deteriorates
Solution Approach 1:
The patent performs preliminary association and temporal alignment of program block information with signal information before display. By pre-processing the data to establish time-axis relationships and organize relevant information together, the system enables operators to immediately see program impacts without needing to manually correlate separate data sources, thus maintaining precision while improving ease of operation.

AI summary
An operation management device includes: a machining program information acquisition unit acquiring information related to machining program executed in the machine tool; a signaling information acquisition unit acquiring signaling information related to signals detected during execution of the machining programs in the machine tool; and an associated-information creation unit associating the information related to the machining program with the signaling information; and a search/display unit displaying the information related to the machining program and the signaling information, which are associated by the associated-information creation unit.
