Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If a washing device is used to supply saline to improve field of view clarity, then the definition of the field of view is improved, but the device requires manual operation by specific personnel which increases labor cost and complexity

Engineering Contradiction:
Improvefield of view clarityVSAvoidoperation complexity
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The system enables self-service operation through automatic sensing and control mechanisms. The washing device automatically detects when washing is needed and activates the pumping system without requiring manual intervention, allowing the gastrointestinal endoscope inspection system to serve itself.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The manual mechanical operation of washing devices is replaced with an automated electronic control system. The controller receives signals from sensors and automatically controls the peristaltic pump to supply washing liquid, substituting the need for manual mechanical operation with an automated electromechanical system.

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

2Illumination intensity

If manual washing devices are used to improve field of view, then clarity is improved, but flow rate adjustment must be made by feeling which makes flow rate non-constant and increases patient discomfort and risk

Engineering Contradiction:
Improvefield of view clarityVSAvoidflow rate stability
Core Design Contradiction:
Illumination intensityVSReliability

Solution Approach 1:

The system incorporates sensors that detect the actual flow rate and provide feedback to the controller. The controller adjusts the peristaltic pump operation based on this feedback to maintain a constant, pre-set flow rate, ensuring reliable and stable washing liquid delivery without manual feeling-based adjustment.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The manual feeling-based flow rate adjustment is replaced with an automated electronic control system that uses sensors and a controller to precisely regulate the peristaltic pump, ensuring constant and reliable flow rate delivery.

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

3Productivity

If washing devices require repeated opening of regulating valves to introduce liquid, then washing can be performed, but the doctor is distracted from the field of view which brings risk to diagnosis and treatment

Engineering Contradiction:
Improvewashing efficiencyVSAvoiddiagnosis and treatment safety
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The system maintains continuous operation by automatically replenishing washing liquid in the washing bottle when the liquid level is low. The controller detects the liquid level and activates the peristaltic pump to introduce more washing liquid, ensuring continuous washing capability without interrupting the medical procedure or requiring doctor intervention.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The system performs self-monitoring and self-replenishment of washing liquid. When the liquid level drops, the system automatically detects this condition and activates the pumping mechanism to restore the liquid level, enabling the device to service itself without external intervention.

Inventive Principle:
Principle #25Self-service

4Illumination intensity

If high flow rate and long washing time are used to improve field of view clarity, then definition is improved, but too much liquid accumulates in patient's body causing nausea and vomiting

Engineering Contradiction:
Improvefield of view definitionVSAvoidpatient discomfort
Core Design Contradiction:
Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

The system dynamically adjusts the washing parameters based on real-time conditions. The controller monitors the washing process and can adjust the flow rate and duration to optimize clarity while preventing excessive liquid accumulation that would cause patient discomfort.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system uses feedback mechanisms to monitor patient response and washing effectiveness, adjusting the flow rate and washing duration accordingly to prevent harmful effects while maintaining field of view clarity.

Inventive Principle:
Principle #23Feedback

5Illumination intensity

If excessive washing liquid is supplied to improve field of view, then clarity is improved, but liquid backflow enters trachea increasing patient risk

Engineering Contradiction:
Improvefield of view clarityVSAvoidpatient risk
Core Design Contradiction:
Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

The system dynamically controls the washing liquid supply based on real-time monitoring of the gastrointestinal tract conditions. The controller adjusts the flow rate to prevent backflow while maintaining sufficient clarity for effective inspection.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system incorporates feedback mechanisms that detect pressure changes and liquid flow patterns to prevent backflow into the trachea. When backflow risk is detected, the controller automatically adjusts or stops the washing liquid supply.

Inventive Principle:
Principle #23Feedback

6Illumination intensity

If washing devices are operated manually to improve field of view, then clarity is improved, but operating time for gastrointestinal endoscope inspection is long

Engineering Contradiction:
Improvefield of view clarityVSAvoidinspection time
Core Design Contradiction:
Illumination intensityVSLoss of time

Solution Approach 1:

The automated system maintains continuous washing capability throughout the inspection procedure, eliminating interruptions for manual washing operations. The peristaltic pump continuously supplies washing liquid as needed, reducing total inspection time while maintaining field of view clarity.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

Manual washing operations are replaced with automated electronic control of the peristaltic pump, eliminating the time required for manual intervention and reducing overall inspection time while maintaining effective field of view clarity.

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

7Productivity

If washing liquid temperature is not controlled to improve field of view, then washing effectiveness is maintained, but temperature is low in winter causing strong irritation

Engineering Contradiction:
Improvewashing effectivenessVSAvoidpatient irritation
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The system changes the temperature parameter of the washing liquid from ambient (cold in winter) to body temperature (37°C) through integrated heating elements. This parameter change maintains washing effectiveness while eliminating thermal irritation to the patient.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The heating elements in the washing bottle raise the temperature of the washing liquid from ambient temperature to body temperature, preventing thermal shock and irritation to the patient's gastrointestinal tract during winter months.

Inventive Principle:
Principle #37Thermal expansion
