Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If medical devices use traditional serial interfaces for data exchange, then device complexity is reduced, but network integration capability and data security are insufficient

Engineering Contradiction:
Improvenetwork integration capabilityVSAvoidinterface device complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces an intermediary interface device that sits between the medical device and the network. This interface device handles all network communication tasks, protocol conversion, and security functions, allowing the medical device itself to remain simple while gaining network capabilities through the intermediary layer.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system is segmented into distinct functional components: the medical device, the interface device, and the network. The interface device is separated as an independent unit that provides network connectivity and security functions, allowing the medical device to maintain its simplicity while the interface device handles complexity.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If medical devices are integrated into modern networks, then data accessibility and monitoring capabilities are improved, but vulnerability to cyberattacks increases

Engineering Contradiction:
Improvedata accessibilityVSAvoidcyberattack vulnerability
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The interface device performs preliminary security actions before data enters the network or reaches remote systems. Security functions such as authentication, encryption, and data validation are performed in advance at the interface device, preventing malicious data from compromising the medical device or network.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The interface device acts as a security intermediary between the medical device and the network. It implements security protocols and filters data to prevent cyberattacks, while still allowing legitimate data exchange to proceed smoothly.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If data exchange capabilities are enhanced with multiple network interfaces, then adaptability to different networks is improved, but device complexity increases

Engineering Contradiction:
Improvenetwork interface compatibilityVSAvoidinterface device structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The interface device is designed with multi-functionality to handle various network protocols and interface types. A single interface device can support multiple network interfaces (Ethernet, wireless, etc.) and protocol conversions, eliminating the need for multiple specialized devices and reducing overall system complexity.

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