Production Management System for Event Data Chronology
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing production management systems for food and pharmaceutical production lines cannot easily determine the cause of production delays, as they lack the capability to analyze the status of individual devices and interconnected processes effectively.
Innovation Solution
A production management system that includes a server device capable of communicating with production line devices, which transmits event data on running status and abnormal states, displays this information chronologically, and includes an image capturing unit to store images associated with event data, allowing for the identification of device-specific issues and product defects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If production lines are divided into multiple interconnected processes for quality management, then manufacturing precision and quality control are improved, but the difficulty of detecting and measuring the cause of production delays increases
Solution Approach 1:
The production line is divided into multiple independent process devices (weighing device, filling device, packaging device, inspection device), each capable of transmitting its own event data separately. This segmentation allows individual process analysis while maintaining overall quality management, resolving the contradiction between quality control and cause detection difficulty.
Solution Approach 2:
A server device acts as an intermediary between production line devices and the display interface. It collects event data from all devices, stores it chronologically, and provides structured information for analysis. This intermediary layer simplifies cause detection by organizing data from multiple interconnected processes in a systematic manner.
2Difficulty of detecting and measuring
If detailed monitoring of each device status is implemented, then the ability to determine the cause of errors is improved, but device complexity and information processing requirements increase
Solution Approach 1:
Only essential event data is extracted and transmitted from each device to the server. The display interface presents only the necessary information (running status, abnormal states, product defects) in chronological order. This extraction approach simplifies the system by filtering out unnecessary data while maintaining cause determination capability.
Solution Approach 2:
Event data from multiple devices is merged and stored in a unified chronological structure at the server. The display interface presents consolidated information showing the sequence of events across all devices. This merging reduces system complexity by providing a single structured view of production status rather than requiring separate monitoring of each device.
3Productivity
If real-time display of production status for all devices is implemented, then productivity and error detection speed are improved, but loss of information and data processing requirements increase
Solution Approach 1:
The system continuously collects event data from devices and updates the display in periodic intervals based on actual events occurring. The server processes and displays information chronologically as events are generated, providing real-time awareness without requiring constant data processing. This periodic update mechanism maintains productivity while managing data processing load efficiently.

AI summary
A production management system includes a server device and production line devices that are a weighing scale, a filling machine, a packaging machine, a printing machine, a printing inspection machine, an appearance inspection machine, a weight sorting machine, a metal detector, an X-ray inspection machine, and a caser. Each production line device and the server device are configured to communicate via a network. Each production line device transmits event data regarding a running status and an abnormal state to the server device. The server device displays the running status and the abnormal state of each production line device in a chronological order based on the received event data, and displays the display which is displayed in the chronological order for each production line device, in a direction intersecting a direction along the chronological order, in an order of arranging the production line devices on the production line.
