Solution Overview

Problem

Manual RFID scanning and updating of vial inventory in storage devices is labor-intensive and prone to errors, leading to inventory control issues, logistical challenges, and potential loss of samples or vials.

Innovation Solution

An RFID system that automatically applies and encodes tags on vials, linking them to a database for tracking, allowing for wireless communication and real-time inventory management, reducing the need for manual scanning and minimizing human error.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual RFID scanning is performed for each vial, then inventory tracking is possible, but labor intensity and time consumption increase significantly

Engineering Contradiction:
Improveinventory tracking accuracyVSAvoidtime for manual scanning
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

Multiple RFID readers are combined into a single storage device that can read multiple vials simultaneously. The device integrates several readers working in parallel, allowing concurrent reading of multiple vials rather than sequential manual scanning, thereby reducing time while maintaining tracking accuracy

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The manual mechanical scanning process is replaced with automated RFID electromagnetic field-based reading. The system uses RFID technology to automatically detect and read vial tags without physical contact or manual intervention, eliminating the need for operators to manually scan each vial

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If manual RFID reading is performed repeatedly, then inventory updates are possible, but human errors increase

Engineering Contradiction:
Improveinventory list accuracyVSAvoidoperational simplicity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The storage device performs self-updating of inventory records by automatically reading RFID tags and updating its internal database without human intervention. The system serves itself by autonomously tracking inventory changes, eliminating human errors associated with manual updating operations

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements automatic feedback loops where RFID readers continuously monitor vial presence and automatically update inventory records. This closed-loop feedback mechanism ensures real-time synchronization between physical inventory and digital records without manual intervention

Inventive Principle:
Principle #23Feedback

3Reliability

If individual manual scanning is performed for each vial addition or removal, then inventory control is possible, but productivity decreases

Engineering Contradiction:
Improveinventory control accuracyVSAvoidinventory update speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

Multiple RFID readers are merged into a single device that operates in parallel to read multiple vials simultaneously. This combining of reading capabilities allows the system to handle multiple inventory operations at once, dramatically increasing productivity while maintaining control accuracy

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The RFID reading operation continues continuously and automatically as vials are added or removed from the storage device. The system maintains constant monitoring and updating without interruption or manual initiation, ensuring continuous inventory control at high speed

Inventive Principle:
Principle #20Continuity of useful action
