Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual operation assignment is used during anomalies, then operator flexibility is maintained, but manufacturing efficiency decreases
Solution Approach 1:
The system automatically performs operation reassignment and operator selection without manual intervention. When an anomaly occurs, the system autonomously identifies affected operations, selects appropriate operators based on work history data, and reallocates operations, enabling the system to serve itself during anomaly response
Solution Approach 2:
The patent replaces manual mechanical decision-making processes with automated information processing. The system uses computer-based algorithms to analyze work history data, determine operator suitability, and execute reassignment, substituting human manual operations with automated computational processes
2Speed
If automated anomaly response is implemented, then response speed increases, but system complexity increases
Solution Approach 1:
The system pre-stores work history data and operator information in the database before anomalies occur. This preliminary preparation of data structures and information allows the system to rapidly process and respond to anomalies without complex real-time data collection, reducing the complexity of the response mechanism
Solution Approach 2:
The patent introduces an information processing system as an intermediary between anomaly detection and operator response. This intermediary automatically processes anomaly information, queries the database for relevant work history data, and determines optimal operator assignments, simplifying the overall system architecture by centralizing the decision-making function
3Productivity
If operation reassignment is delayed, then system stability is maintained, but manufacturing efficiency decreases
Solution Approach 1:
The system dynamically adjusts operation assignments based on real-time anomaly conditions and operator availability. Rather than maintaining fixed assignments, the system flexibly reallocates operations when anomalies occur, allowing the operational structure to adapt dynamically to changing conditions while maintaining overall system stability
Data Source
AI summary
An information processing system includes a storage which stores a plurality of operators, in association with current operations and work histories; a detection unit which detects an anomaly; an anomaly responder determination unit which determines a first operator who is intended to respond to the anomaly, from among the plurality of operators who are stored in the storage, on the basis of the work histories; an operation assignment unit which carries out an assignment of a new operation cluster upon a second operator, an unfulfilled operation identification unit which identifies an unfulfilled operation which has arisen due to the first operator responding to the anomaly; and an operator determination unit which determines an operator who is intended to respond to the unfulfilled operation on the basis of the current operations of each of the operators which are stored in the storage.
