Solution Overview

Problem

Current methods for tracking and maintaining tools in operation rooms are inefficient, leading to errors in tool counting, increased resource utilization, and risks associated with tools being left inside patients, and require manual labor for record-keeping and tracking, with existing RFID tags posing challenges in adhesion and orientation recognition.

Innovation Solution

A compact identification tag system with a small base and larger attachment, featuring an encasement with an RFID circuit that can transmit unique identifiers wirelessly, designed to be securely attached to tools using laser or ultrasonic welding, ensuring compatibility with sterilization processes and orientation-independent identification.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a traditional RFID tag is attached to a tool, then the tool can be identified, but the tag may interfere with the tool's use or fall off during sterilization

Engineering Contradiction:
Improvetag adhesion reliabilityVSAvoidtool usability
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The identification tag is divided into two separate components: a small base attached to the tool and a larger identification attachment containing the RFID circuit. This segmentation allows the base to be minimally invasive to tool usability while the identification attachment provides robust identification functionality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The base is pre-attached to the tool before sterilization, and the identification attachment is subsequently connected to the base. This preliminary attachment ensures the tag system is in place before the tool undergoes sterilization processes, preventing loss or interference during critical operations.

Inventive Principle:
Principle #10Preliminary action

2Loss of information

If manual counting of tools is performed, then tool tracking is possible, but it consumes significant time and resources

Engineering Contradiction:
Improvetool tracking accuracyVSAvoidcounting time
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The manual mechanical counting process is replaced with an automated electronic identification system using RFID technology. The identification circuit wirelessly transmits tool information, eliminating the need for manual counting and reducing both time and resource consumption while improving accuracy.

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

Solution Approach 2:

The identification tag system enables automatic tool identification and tracking without requiring human intervention. The RFID circuit self-transmits identification information when queried, allowing the system to service itself rather than requiring manual counting by personnel.

Inventive Principle:
Principle #25Self-service

3Reliability

If tools are thoroughly tracked and maintained, then tool lifecycle management is improved, but resource consumption increases

Engineering Contradiction:
Improvetool lifecycle managementVSAvoidresource consumption
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

Manual record-keeping and tracking processes are replaced with an automated RFID-based identification and tracking system. This substitution reduces the labor and resources required for tool lifecycle management while maintaining or improving reliability through automated data collection and monitoring.

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