Injection Molding Cell Management System Centralized Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In injection molding cells, releasing the input/operation prohibition state for multiple devices is complex and requires learning different release operations for each device, leading to inefficiency and increased costs due to the need for separate authentication systems like fingerprint authentication units.
Innovation Solution
An injection molding cell management system that uses a worker identification information input unit and a prohibition state releasing unit to collectively manage the release authorization for all injection molding machine and peripheral devices based on worker identification, such as smart cards or passwords, eliminating the need for individual device operations and authentication systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate authentication systems like fingerprint authentication units are provided for each device, then device security and access control are improved, but system cost and complexity increase
Solution Approach 1:
The patent merges separate authentication systems into a single centralized authentication unit that manages access for multiple devices. Instead of providing fingerprint authentication units for each device, one centralized unit handles authentication for the injection molding machine, molding take-out machine, and other peripheral devices, thereby reducing system complexity and cost while maintaining security.
Solution Approach 2:
The centralized authentication unit serves multiple functions across different devices. It authenticates workers for the injection molding machine, molding take-out machine, and other peripheral devices, making the authentication system universal and eliminating the need for device-specific authentication units.
2Manufacturing precision
If separate release operations are required for each device, then device-specific control precision is improved, but operational efficiency and ease of use deteriorate
Solution Approach 1:
The patent combines multiple device-specific release operations into a single centralized release operation. The centralized control unit manages the release of prohibition states for all devices simultaneously through one operation, eliminating the need for workers to perform separate release operations for each device while maintaining appropriate control precision through centralized management.
Solution Approach 2:
The centralized control unit provides universal control functionality across multiple devices. A single release operation managed by the centralized control unit can release prohibition states for the injection molding machine, molding take-out machine, and other peripheral devices, making the control system universal and significantly improving operational efficiency.
3Reliability
If device-specific authentication and release operations are implemented, then individual device security is improved, but worker training requirements and operational complexity increase
Solution Approach 1:
The patent merges device-specific authentication and release operations into centralized operations. Workers perform authentication and release operations through a single centralized interface rather than learning multiple device-specific procedures, thereby maintaining security through centralized management while significantly simplifying operations and reducing training requirements.

AI summary
An injection molding cell management system includes a plurality of injection molding cell each having an injection molding machine, its peripheral device and an injection molding cell management unit and a host management unit. The injection molding cell management unit includes a worker identification information input unit, which accepts input of worker identification information for identifying a worker who performs input and/or operation of the injection molding machine and its peripheral device, and a prohibition state releasing unit which releases a prohibition state of the input and/or operation of the injection molding machine and its peripheral device, based on the worker identification.
