Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current techniques for monitoring production lines in factory automation do not provide a method to visually link production data with inspection data, making it difficult for users to recognize and analyze the relationship between the two.

Innovation Solution

A data collection device that collects data from production processes, acquires product identifiers, links inspection results with collected data, and generates visualization data to display the linked information, allowing for prioritization based on deviation degrees and inspection types.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If data collection and linking is implemented, then data visualization capability is improved, but device complexity increases

Engineering Contradiction:

Improvedata visualization capabilityVSAvoidsystem complexity

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The patent introduces a data collection device as an intermediary component that sits between the production line processes and the visualization system. This device collects data from multiple processes, links it with inspection results, and prepares it for visualization, thereby reducing the complexity burden on the overall system while improving data visualization capability

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The data collection device automatically performs data collection, linking, and preparation functions without requiring manual intervention. It self-manages the complex tasks of gathering data from multiple processes, associating it with inspection results, and formatting it for visualization, thus improving capability while keeping operational complexity low

Inventive Principle:

Principle #25Self-service

2Measurement precision

If detailed data collection from each process is performed, then measurement precision is improved, but loss of time increases

Engineering Contradiction:

Improvedata collection precisionVSAvoiddata collection time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The data collection device performs preliminary data collection and linking operations during the production process itself, rather than after completion. By collecting data from each process as it occurs and immediately linking it with inspection results, the system achieves precise measurement without significant time loss

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system maintains continuous data collection from multiple processes simultaneously, rather than sequentially. This parallel continuous operation ensures that detailed data is gathered with high precision while minimizing the total time required, as all processes contribute data concurrently

Inventive Principle:

Principle #20Continuity of useful action

AI summary

A data collection device includes a data collection unit that collects data of a data item related to production work from a production line that produces a target through a plurality of processes, and an acquisition unit that acquires an identifier of the target produced in the production line. The data collection device links, for each process, the identifier of the target and an inspection result of the target with collection data collected in a period in which the production work is performed on the target in the process, and generates, for each process, visualization data visualizing the linked collection data of the process.
