Glove Logging System for Isolator Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current airtightness inspection methods for work gloves used in isolators and RABS do not accurately consider the status of use, leading to inefficient inspections and improper timing of replacements, which can compromise safety and efficiency.
Innovation Solution
A glove/logging system that uses RFID tags attached to workers and work gloves, with readers positioned at the glove port, to record and store information on operator name, frequency of use, period of use, and details of work, enabling accurate determination of inspection and replacement times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If airtightness inspection is performed based on fixed time intervals, then inspection simplicity is maintained, but inspection timing accuracy deteriorates leading to either premature replacement or delayed detection of glove failures
Solution Approach 1:
The system performs preliminary recording of glove usage status, operator information, and work details through RFID tags before inspection is needed. This preliminary data collection enables accurate determination of inspection timing based on actual usage patterns rather than fixed intervals, resolving the contradiction between inspection accuracy and system complexity.
Solution Approach 2:
The system establishes feedback loops where RFID readers continuously monitor glove usage status and transmit data to the information device. This feedback mechanism enables dynamic adjustment of inspection timing based on actual glove condition and usage intensity, achieving precise inspection scheduling without requiring complex manual assessment procedures.
2Reliability
If RFID tracking system is implemented to monitor glove usage status, then inspection accuracy is improved, but system complexity and initial investment increase
Solution Approach 1:
The RFID system is designed with multi-functionality to justify its complexity: it simultaneously tracks glove location, records usage duration, identifies operators, monitors work types, and triggers inspection alerts. This universal application across multiple functions maximizes the reliability benefit while distributing the complexity burden across diverse operational needs.
Solution Approach 2:
The system enables self-service operation where the RFID tags and readers automatically capture and transmit glove usage data without manual intervention. The information device autonomously processes the data and generates inspection notifications, reducing the operational complexity burden on staff while maintaining high tracking reliability.
3Reliability
If work gloves are replaced frequently to ensure safety, then safety is improved, but resource waste and cost increase
Solution Approach 1:
The system performs preliminary monitoring of glove usage status, accumulating data on usage duration, work intensity, and environmental conditions. This preliminary information enables determination of the optimal replacement timing for each glove individually, allowing extension of service life for gloves that remain within safety parameters while ensuring timely replacement of those approaching degradation thresholds.
Solution Approach 2:
The system transitions from static, uniform replacement schedules to dynamic, individualized replacement timing based on actual usage patterns. Each glove's replacement schedule is dynamically adjusted according to its specific usage history, work type exposure, and monitored condition, optimizing the balance between safety requirements and resource conservation.

AI summary
The present invention provides a glove/logging system capable of accurately determining periods for glove airtightness inspection and replacement and improving the safety of a work glove in use and the work efficiency by recording and storing the status of use such as the operator name, the frequency of use, the period of use, and the details of work for an individual pair of work gloves attached to a device such as an isolator, and retroactively checking improper work and device abnormalities by tracing glove operations upon occurrence of operational abnormalities. The glove/logging system is configured to record and store information on the status of use for a work glove, and include an operator tag, a glove tag, a reader for reading information from the tags, and an information device for recording and storing information. The reader is configured to receive information from the operator tag that passes through the reception region or stops therein or the glove tag via the antenna to communicate the information with the information device.
