Centralized Biometric Access Control for Molding Machines and Cleanrooms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing systems for access control on molded product production sites require manual input of authentication information (ID and password) at each machine or room, which is cumbersome for operators wearing protective equipment, and carrying an ID card is undesirable.
Innovation Solution
A management system with a common authentication information registration server that stores operator-specific information, allowing biometric authentication through input accepters, and controllers to manage access to multiple machines and rooms based on stored authority levels, eliminating the need for manual input and ID cards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual input of ID and password is required at each machine or room, then authentication can be performed, but operator convenience deteriorates and hygiene is compromised due to protective equipment
Solution Approach 1:
The patent replaces the mechanical/manual authentication system (manual input of ID and password) with a biometric authentication system using optical recognition. The camera captures images of the operator's face or other biometric features, and the authentication is performed automatically without manual input, thus maintaining reliability while improving ease of operation.
Solution Approach 2:
The authentication system performs self-service by automatically capturing biometric data and comparing it with stored information without requiring operator intervention. The system autonomously completes the authentication process, eliminating the need for operators to manually input credentials while wearing protective equipment.
2Reliability
If authentication information is registered in each machine's controller individually, then access control can be implemented, but system complexity increases and registration becomes troublesome
Solution Approach 1:
The patent merges the authentication information storage function into a single centralized server rather than distributing it across multiple machine controllers. This consolidation reduces system complexity by eliminating redundant storage instances while maintaining access control reliability through centralized management of authentication data.
Solution Approach 2:
The centralized server provides universal authentication information storage and management for all machines and rooms in the system. Instead of each controller having its own dedicated authentication storage, a single multi-functional server serves all access control points, reducing overall system complexity while maintaining comprehensive access control capability.
3Object-affected harmful factors
If operators wear protective equipment, then hygiene and safety are maintained, but manual authentication becomes difficult and cumbersome
Solution Approach 1:
The patent substitutes manual authentication operations with automated biometric recognition. The optical camera system captures biometric data without physical contact, and the automated processing eliminates the need for operators to manipulate authentication devices while wearing protective equipment, thus maintaining hygiene while improving ease of operation.
Solution Approach 2:
The system creates an optical copy (image) of the operator's biometric features and compares it with stored reference data. This copying approach allows authentication without physical contact or manual handling, making it compatible with protective equipment requirements while maintaining ease of operation.
