Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If wireless communication is performed in a wide area with multiple medical devices, then the coverage and functionality are improved, but electromagnetic noise interference increases

Engineering Contradiction:
Improvecommunication coverage areaVSAvoidelectromagnetic noise interference
Core Design Contradiction:
Area of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The system performs periodic wave detection before data transmission to identify periods when electromagnetic noise is minimal. The control unit repeatedly detects radio wave environments and adjusts transmission timing accordingly, transmitting control data only during periods when interference from medical devices like electric scalpels is low, thus maintaining reliable communication across wide areas.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system performs preliminary wave detection before actual data transmission to assess the radio wave environment. By detecting the presence and intensity of electromagnetic noise from other medical devices in advance, the control unit can determine the optimal timing for transmission, preventing interference before it occurs.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If control data is transmitted simultaneously with image data, then communication efficiency is improved, but data transmission reliability deteriorates due to noise interference

Engineering Contradiction:
Improvecommunication efficiencyVSAvoiddata transmission reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system alternates between image data transmission and control data transmission based on detected noise levels. Image data is transmitted during periods of low interference, while control data is transmitted during periods when electromagnetic noise from medical devices is minimal, ensuring both types of data maintain high transmission reliability.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The control unit acts as an intermediary that manages the transmission timing of different data types. It monitors the radio wave environment and mediates between image data transmission and control data transmission, scheduling control data transmission during periods when electromagnetic interference is low, thus protecting the reliability of critical control communications.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If the number of medical devices is increased, then the system functionality is improved, but the complexity of managing transmission timing increases

Engineering Contradiction:
Improvesystem functionalityVSAvoidtransmission timing management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Each medical device equipped with the wireless communication unit autonomously performs wave detection and adjusts its own transmission timing based on the detected radio wave environment. The control unit within each device independently determines optimal transmission periods without requiring complex centralized coordination, simplifying the management of multiple devices while maintaining reliable communication.

Inventive Principle:
Principle #25Self-service
