Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a robotic system is used to manipulate the uterus, then procedural accuracy and consistency are improved, but device complexity increases

Engineering Contradiction:
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The robotic system divides the uterus manipulation task into multiple independent components: a robotic arm for positioning, a uterine manipulator with colpotomy cup for grasping, and inflatable balloons for stabilization. Each component operates independently but coordinates through a centralized control system, allowing precise control while managing complexity through modular design

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system incorporates sensors that detect the position and orientation of the uterine manipulator in real-time, feeding this information back to the control system. This closed-loop feedback mechanism enables the robotic system to automatically adjust and maintain precise positioning of the uterus during surgical procedures

Inventive Principle:
Principle #23Feedback

2Reliability

If robotic control is implemented for uterine manipulation, then human error is reduced, but ease of operation decreases

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The robotic system performs uterine manipulation autonomously based on pre-programmed surgical pathways and real-time sensor feedback. The system self-adjusts positioning and orientation without requiring continuous manual intervention, reducing human error while maintaining operational simplicity through automated control

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system replaces manual mechanical manipulation by human surgeons with automated robotic control. The robotic arm and uterine manipulator execute precise movements based on digital planning and sensor feedback, eliminating human variability and error while the high-level control interface maintains ease of operation for the surgical team

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

3Productivity

If precise positioning and orientation is achieved, then surgical efficiency is improved, but device complexity increases

Engineering Contradiction:
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The robotic system performs preliminary positioning and orientation of the uterine manipulator before the main surgical procedure begins. Pre-operative planning defines the optimal surgical pathway, and the robotic system executes this plan in advance, establishing precise initial positioning that improves surgical efficiency while the automated planning reduces the complexity of real-time adjustments

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Real-time sensors monitor the position and orientation of the uterine manipulator, providing continuous feedback to the control system. This enables automatic adjustments to maintain optimal positioning throughout the procedure, improving surgical efficiency through precise control while the automated feedback loop manages the complexity of continuous monitoring and adjustment

Inventive Principle:
Principle #23Feedback
