Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for managing and identifying cryogenic samples, such as those in fertility clinics, are manual, error-prone, and require on-site presence, leading to inefficiencies and risks of sample loss or misplacement.
Innovation Solution
The implementation of a system that uses RFID tags attached to cryogenic containers, allowing for inventory tracking and automated check-in/check-out through scanning by RFID scanners, both within the cryogenic fluid and at entry/exit points, facilitated by computing devices and databases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual inventory tracking is used, then device complexity is reduced, but productivity and reliability deteriorate
Solution Approach 1:
The patent replaces manual mechanical inventory tracking with an automated RFID-based system. RFID tags attached to containers are scanned by readers, automatically updating the database without human intervention, thus dramatically improving productivity while the system manages its own complexity through software automation
Solution Approach 2:
The inventory system performs self-tracking and self-monitoring through RFID technology. The system automatically detects container movements, updates inventory records, and generates alerts without requiring continuous human oversight, enabling the system to serve itself in the inventory management process
2Measurement precision
If manual sample verification is used, then device complexity is reduced, but measurement precision and reliability deteriorate
Solution Approach 1:
The patent replaces manual visual verification of sample labels with automated optical scanning systems. Cameras and image recognition algorithms automatically read labels and verify sample identities, eliminating human error in the verification process while the software system manages the complexity of automated recognition
Solution Approach 2:
The system creates digital copies of sample labels and metadata in the database. Instead of relying on physical labels that can be misread, the system stores precise digital representations that can be automatically read, verified, and cross-checked, improving measurement precision through digital accuracy
3Reliability
If on-site monitoring is required, then loss of information is reduced, but loss of time and productivity deteriorate
Solution Approach 1:
The system provides continuous self-monitoring of sample containers through RFID readers and sensors that automatically detect movements, temperature changes, and security events. The system alerts personnel only when anomalies occur, eliminating the need for continuous on-site monitoring while maintaining high reliability through automated surveillance
Solution Approach 2:
The system implements real-time feedback loops where sensors continuously monitor sample conditions and automatically trigger alerts or actions when thresholds are exceeded. This continuous feedback mechanism maintains security and reliability without requiring constant human presence, as the system self-regulates and notifies appropriate personnel

Data Source
AI summary
A method and related system for specimen identification, management, and procedural monitoring are described. Specimens can be cryogenic samples, housed in cryogenic containers having attached, integral, or physically included RFID tags, which can be scanned using an RFID scanner, while the cryogenic containers with samples are in the cryogenic fluid. Inventory tracking of the samples in the cryogenic containers can be performed with a computing device based on scanning the RFID tags. Also described are a method and related system that include a microscopic camera and one or more display screens and allow efficient and accurate identification of sample identifiable information on the sample, two-person verification from a central and remote locations, e.g., via videoconferencing capability, documentation, monitoring (e.g., quality control), and training. A method and related system for monitoring a procedure, e.g., a microscopic procedure, at two or more locations using microscopic camera and computing devices are also provided.
