VSEngineering Contradiction Analysis

1Adaptability or versatility

If the diameter of the endoscope tube is changed to adapt to different respiratory gas pathways, then the adaptability of the medical apparatus is improved, but the effort required for reconnection and ventilation parameter adjustment increases

Engineering Contradiction:

ImproveadaptabilityVSAvoidease of operation

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system performs preliminary detection of the endoscope tube diameter using sensors before the procedure begins. The control unit is pre-programmed with correction factors for different diameters, allowing automatic ventilation parameter adjustment without manual intervention during the procedure.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors the endoscope tube diameter through sensors and provides feedback to the control unit, which automatically adjusts ventilation parameters in real-time. This closed-loop feedback mechanism ensures optimal ventilation settings are maintained throughout the procedure.

Inventive Principle:

Principle #23Feedback

2Quantity of substance

If the endoscope tube diameter is increased to accommodate larger respiratory gas pathways, then the ventilation capacity is improved, but the loss of time for complete exchange and reattachment increases

Engineering Contradiction:

Core Design Contradiction:

Quantity of substanceVSLoss of time

Solution Approach 1:

The correct endoscope tube diameter is selected and configured before the procedure begins. The system pre-calculates and stores the appropriate ventilation parameters and correction factors, eliminating the need for time-consuming adjustments during the procedure.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system automatically adjusts ventilation parameters based on the detected endoscope tube diameter without requiring manual intervention. The control unit self-regulates the ventilation settings, freeing the operator from time-consuming manual adjustments.

Inventive Principle:

Principle #25Self-service

3Ease of operation

If the endoscope tube diameter is decreased for smaller respiratory gas pathways, then the ease of insertion is improved, but the ventilation volume decreases sharply

Engineering Contradiction:

Improveease of insertionVSAvoidventilation volume

Core Design Contradiction:

Ease of operationVSQuantity of substance

Solution Approach 1:

The system dynamically changes ventilation parameters based on the endoscope tube diameter. When a smaller diameter tube is detected, the control unit automatically adjusts ventilation settings to compensate for the reduced cross-sectional area, maintaining adequate ventilation volume despite the smaller tube size.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

Sensors continuously monitor the endoscope tube diameter and provide feedback to the control unit, which adjusts ventilation parameters in real-time to maintain optimal ventilation volume regardless of tube size.

Inventive Principle:

4Measurement precision

If manual adjustment of ventilation parameters is performed for each endoscope tube diameter, then the precision of ventilation settings is improved, but the complexity of the operation increases

Engineering Contradiction:

Solution Approach 1:

The system automatically determines the endoscope tube diameter through sensors and self-adjusts ventilation parameters without requiring manual intervention. The control unit processes sensor data and applies appropriate correction factors autonomously, eliminating complex manual adjustment procedures.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The manual mechanical process of measuring tube diameter and calculating ventilation adjustments is replaced by an automated electronic system. Sensors electronically detect tube dimensions, and the control unit computationally determines the appropriate ventilation settings, substituting manual operations with automated electronic processing.
