Solution Overview

Problem

Existing cleaning, disinfecting, and sterilization devices for medical instruments lack secure communication methods between reprocessing devices and remotely connected accessories, relying on public wireless networks that are insecure and unreliable.

Innovation Solution

The implementation of wireless communication means within the cleaning, disinfecting, and sterilization device to create a secure wireless local area network (WLAN) using the Wi-Fi standard, allowing remote accessories to communicate safely and reliably with the device's control unit, and optionally providing internet access through an internet bridge.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If public wireless networks are used for communication between reprocessing device and accessories, then ease of operation is improved, but reliability and security of communication deteriorate

Engineering Contradiction:
Improveease of operationVSAvoidreliability of communication
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent introduces a dedicated wireless communication interface as an intermediary component that establishes a direct communication link between the reprocessing device and accessories. This intermediary eliminates reliance on public wireless networks by creating a private communication channel, thereby maintaining ease of operation while significantly improving reliability and security of data transfer.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If wireless communication means are integrated into the device, then reliability of communication is improved, but device complexity increases

Engineering Contradiction:
Improvereliability of communicationVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The wireless communication interface is designed with multi-functionality, serving both as a reliable communication channel and as an internet bridge for providing network access to accessories. By combining multiple functions into a single component, the patent improves communication reliability without proportionally increasing device complexity.

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

3Reliability

If wireless local area network is created within the device, then security of information transfer is improved, but loss of time for network setup increases

Engineering Contradiction:
Improvesecurity of information transferVSAvoidtime for network setup
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The wireless communication interface is pre-configured and automatically activated when accessories are connected to the reprocessing device. This preliminary preparation eliminates the need for manual network setup procedures, allowing accessories to join the secure wireless network immediately upon connection, thereby maintaining high security while minimizing setup time.

Inventive Principle:
Principle #10Preliminary action
