Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If manual threading and shaping of guide wire is performed, then the guide wire can be navigated into the patient, but the operator must be adjacent to the patient and exposed to X-ray radiation
Solution Approach 1:
The patent replaces manual mechanical threading and shaping operations with an automated robotic system. The robotic device includes a guide wire delivery mechanism and a shaping mechanism that automatically forms the guide wire tip without requiring the operator to be physically present near the patient, thereby eliminating X-ray radiation exposure while maintaining the necessary threading and shaping functions.
Solution Approach 2:
The robotic system acts as an intermediary between the operator and the guide wire manipulation process. The operator controls the robotic device from a remote location, and the robotic device performs all interactions with the guide wire and patient, serving as a mediator that transfers the operator's intent to the physical manipulation without direct contact, thus protecting the operator from radiation exposure.
2Shape
If the guide wire tip is manually shaped, then navigation assistance is provided, but the operator requires direct access to the guide wire for shaping
Solution Approach 1:
The robotic device integrates multiple functions into a single system: it delivers the guide wire, shapes the tip, and enables remote operation. The shaping mechanism is incorporated as part of the robotic device's tool, allowing the same device to perform both delivery and shaping functions, thereby managing complexity through functional integration rather than separate manual operations.
Solution Approach 2:
The robotic system performs the tip shaping action as part of the automated delivery sequence, preparing the guide wire tip in advance before insertion into the patient. This preliminary shaping is done remotely by the robotic device, eliminating the need for the operator to manually shape the tip after accessing the patient area.
3Reliability
If remote operation is implemented, then operator safety is improved, but automated tip shaping capability is required
Solution Approach 1:
The patent replaces manual mechanical operations with an automated robotic system that can be controlled remotely. The robotic device incorporates a shaping mechanism that automatically forms the guide wire tip based on programmed instructions, eliminating the need for the operator to be physically present and thereby improving safety while implementing the necessary automation.
Solution Approach 2:
The robotic system is designed to perform the tip shaping operation autonomously once programmed or directed by the operator from a remote location. The shaping mechanism automatically executes the shaping function without requiring continuous manual intervention, allowing the system to serve itself in performing the delicate shaping task while the operator maintains oversight from a safe distance.
