Cross-Line Component Tracking Without Central Server Failure Risk
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing component mounting systems rely on centralized management apparatuses, which can lead to system failures and inefficiencies when communication is disrupted, and lack direct communication between mounting lines, causing inaccuracies in component tracking and management.
Innovation Solution
A component mounting system with line management apparatuses that communicate directly over a central network, allowing for cross-line communication to manage and track component supplies without a centralized server, enabling accurate monitoring and updating of component availability across multiple mounting lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a centralized management apparatus is used to manage multiple mounting lines, then integration and control are improved, but system reliability deteriorates due to single-point failure risk
Solution Approach 1:
The patent divides the centralized management system into multiple independent line management apparatuses, each managing a specific mounting line. This segmentation eliminates the single-point failure risk of a centralized system while maintaining integration capabilities through inter-apparatus communication. Each apparatus operates independently but can share data with others, achieving both decentralization for reliability and coordination for integration.
2Loss of information
If a centralized server is used for data management, then data centralization is improved, but communication efficiency deteriorates due to indirect communication paths
Solution Approach 1:
The patent combines direct peer-to-peer communication capabilities with distributed data storage across multiple line management apparatuses. Each apparatus maintains local data and can directly communicate with other apparatuses without routing through a central server, reducing communication hops and improving efficiency while maintaining data centralization through the networked distributed system.
3Device complexity
If mounting lines operate independently without cross-line communication, then system simplicity is improved, but component tracking accuracy deteriorates
Solution Approach 1:
The patent implements feedback mechanisms where line management apparatuses exchange component usage data and supply status information with each other. When a component supply is transferred between mounting lines or when supplies are depleted, the system receives feedback from affected lines and updates tracking information accordingly, maintaining accurate component tracking across the distributed system without requiring complex centralized management.
Data Source
AI summary
A component mounting system has a supply reel accommodating a component, a plurality of mounting lines each having a mounting apparatus and a line management apparatus, and a central network that provides direct communication between the line management apparatuses of each mounting line. A remaining number of components on the supply reel is determined based on cross line communication between the line management apparatuses and comparison of data at different times stored on the line management apparatuses. Such architecture does not require the use of a central server. Rather, the system is a material information exchange system without a single point of failure, where no one computer failure can cause an entire factory shutdown.
