Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If manual control of procedure tool is used, then operator can directly control the tool, but operator's radiation exposure increases and insertion efficiency decreases
Solution Approach 1:
The patent introduces a master device as an intermediary between the operator and the procedure tool. The master device includes an operation rod with measurement units that detect translational and rotational motions, converting them into remote control signals that actuate the slave device and procedure tool. This intermediary system reduces radiation exposure by allowing remote operation while maintaining precise control through motion detection and signal transmission mechanisms.
2Object-affected harmful factors
If simple remote control is used, then radiation exposure is reduced, but control precision is insufficient for challenging vascular regions
Solution Approach 1:
The master device incorporates measurement units that detect the operator's manual operations on the operation rod and provide feedback signals. The first measurement unit detects translational motion and the second measurement unit detects rotational motion, converting these physical movements into precise remote control signals. This feedback mechanism ensures that even subtle operator inputs are accurately transmitted to control the procedure tool in challenging vascular regions.
Solution Approach 2:
The patent replaces direct mechanical control with a system that detects mechanical motions and converts them into control signals. Instead of direct mechanical linkage between the operator's hand and the procedure tool, the system uses measurement units to detect motions and generate corresponding remote control signals, enabling precise control without direct mechanical connection and reducing radiation exposure.
3Measurement precision
If multiple measurement units are added to detect both translational and rotational motions, then control precision is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple measurement functions into an integrated master device structure. The first measurement unit for translational motion and the second measurement unit for rotational motion are merged within the same device housing, sharing common components such as the operation rod and control electronics. This integration reduces overall system complexity while maintaining the capability to detect both types of motions with high precision.
