Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If value stream maps are applied to track production metrics, then production control capability is improved, but system complexity increases making timely decisions difficult
Solution Approach 1:
The cognitive architecture segments the complex production control system into distinct modules: perceptual module for data acquisition, cognitive module for reasoning with production rules and memory buffers, and motor module for decision execution. This segmentation manages complexity while maintaining comprehensive production control capability.
Solution Approach 2:
The patent introduces an imaginal memory buffer as an intermediary between raw sensor data and decision-making processes. This buffer temporarily stores and structures production data, enabling the cognitive module to process complex information systematically without being overwhelmed by raw data volume.
2Measurement precision
If comprehensive production data is collected for analysis, then decision quality is improved, but processing time increases
Solution Approach 1:
The perceptual module performs preliminary processing of sensor data before it reaches the cognitive module, organizing and filtering information in advance. This preliminary action reduces the processing burden on subsequent modules, maintaining decision quality while reducing overall processing time.
Solution Approach 2:
The cognitive architecture operates continuously with parallel processing capabilities, where the perceptual module continuously acquires data while the cognitive module simultaneously processes information using production rules. This continuous operation eliminates idle time and maintains rapid decision-making despite comprehensive data analysis.
