Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information collection systems for industrial equipment lack efficient methods to associate and manage processing information across multiple steps in a product manufacturing line, leading to difficulties in traceability and requiring additional burdens on processing apparatuses.
Innovation Solution
An information collection system that includes processing circuitry to collect and associate processing information sets from multiple processing apparatuses using link identifiers, enabling linkage between processing steps, thereby managing traceability without additional software burdens on the manufacturing line.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If processing information is collected from multiple processing apparatuses across different manufacturing steps, then traceability of products is improved, but the complexity of managing and associating information from multiple sources increases
Solution Approach 1:
The control apparatus serves as an intermediary that receives processing information from multiple processing apparatuses, assigns link identifiers to associate information across different manufacturing steps, and manages the overall traceability system. This centralizes the complexity of information association while keeping individual processing apparatuses simple.
Solution Approach 2:
The system introduces link identifiers as a new parameter that changes and evolves through different manufacturing steps. Each processing apparatus adds its processing information with a specific link identifier, allowing the information to be tracked and associated across steps without requiring complex inter-apparatus communication protocols.
2Loss of information
If link identifiers are assigned to associate processing information sets across multiple steps, then information association capability is improved, but the burden on processing apparatuses increases
Solution Approach 1:
The control apparatus acts as an intermediary that handles the complex task of assigning and managing link identifiers. Processing apparatuses only need to send their processing information to the control apparatus, which then assigns the appropriate link identifier and associates the information with the correct product and manufacturing step, reducing the burden on individual processing apparatuses.
Solution Approach 2:
The control apparatus automatically assigns link identifiers and performs information association without requiring manual intervention or complex software modifications on the processing apparatuses. The system self-manages the information association process, allowing processing apparatuses to operate independently while still contributing to the overall traceability.
3Reliability
If traceability management is implemented across multiple processing apparatuses, then product tracking reliability is improved, but additional software additions on existing apparatuses are required
Solution Approach 1:
The control apparatus serves as an intermediary that centralizes the traceability management functionality. Existing processing apparatuses only need to communicate with the control apparatus, which handles all the complex traceability logic, information association, and link identifier management. This approach implements product tracking without requiring significant software modifications to existing processing apparatuses.

AI summary
An information system for industrial equipment includes processing circuitry that controls processing apparatuses that each execute a predetermined process with respect to at least one workpiece, respectively collects, from the processing apparatuses, processing information sets that are respectively related to processing steps executed by the processing apparatuses until one corresponding product is manufactured from the at least one workpiece, and associates the processing information sets by assigning to the processing information sets a link identifier that permits a linkage between respective steps of the processing steps related to the one corresponding product.
