Solution Overview

Problem

Current methods for ensuring the hygiene of medical devices rely on manual traceability, which is prone to errors and falsifications, making it uncertain whether a probe can be used safely from a hygienic standpoint.

Innovation Solution

An automated system using an information acquisition and processing system with RFID technology to record and associate disinfection and usage information of medical devices, ensuring that the devices are only used if properly disinfected and within a safe timeframe, prohibiting use if hygiene standards are not met.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual traceability methods are used to track disinfection and use of medical devices, then the system is simple to implement, but the reliability of hygiene traceability deteriorates due to errors and falsifications by medical personnel

Engineering Contradiction:
Improvehygiene traceabilityVSAvoidtraceability system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The medical device autonomously records its own disinfection and use history through integrated sensors and memory, eliminating dependency on manual recording by medical personnel. The device self-monitors its hygiene status and communicates this information automatically, thereby improving reliability without requiring complex external tracking systems.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical recording processes with electronic automation. Sensors automatically detect disinfection events, usage conditions, and storage time, while digital memory stores this information. This substitution eliminates human error and falsification while maintaining system simplicity through integrated electronics rather than complex administrative procedures.

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

2Reliability

If automated information acquisition and processing systems are implemented to track medical device use, then the reliability of hygiene traceability is improved, but the device complexity increases

Engineering Contradiction:
Improvehygiene traceabilityVSAvoidinformation processing system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines identification means, information acquisition sensors, memory storage, and communication interfaces into a single integrated unit attached to the medical device. This merging consolidates multiple functions into one compact system, improving reliability through automated tracking while minimizing the increase in device complexity by avoiding separate distributed systems.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated unit serves multiple functions simultaneously: it identifies the device, monitors disinfection events, tracks usage conditions, records storage time, and communicates with external systems. This multi-functionality reduces the need for multiple separate systems, thereby improving traceability reliability without proportionally increasing overall system complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Productivity

If manual recording of disinfection and use information is required, then the system complexity is low, but the time needed for traceability verification increases and productivity decreases

Engineering Contradiction:
Improvetraceability verification speedVSAvoidmonitoring system
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system continuously and automatically records disinfection events, usage conditions, and storage time information in real-time as they occur. This preliminary automated documentation eliminates the need for later manual verification processes, allowing instant access to complete traceability histories and dramatically speeding up verification while maintaining low operational complexity.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The integrated unit automatically provides feedback information about the device's hygiene status and usage history to external systems and users. This real-time feedback mechanism eliminates manual verification steps, enabling rapid traceability checks while the automated recording continues in the background, thus improving productivity without requiring complex manual monitoring procedures.

Inventive Principle:
Principle #23Feedback
