Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional simulation methods are used for medical training, then the system is simple and easy to operate, but the realism and accuracy of instrument simulation are insufficient
Solution Approach 1:
The patent creates virtual copies of real medical instruments (stents, balloons, catheters) and vessels through 3D computer modeling. These digital replicas replicate the geometric characteristics, mechanical properties, and behavioral features of actual instruments, enabling realistic simulation without physical prototypes. The virtual instruments respond to user manipulation as real instruments would, providing authentic training experience.
Solution Approach 2:
The patent replaces physical mechanical simulation systems with computer-based virtual reality simulation. Instead of using physical models and mechanical feedback devices, the system uses software algorithms to calculate instrument-vessel interactions, force feedback, and deformation behaviors. This substitution enables complex physiological simulations that would be impractical with purely mechanical systems.
2Reliability
If detailed simulation of self-expanding instruments is implemented, then the training effectiveness improves, but the computational requirements and system resources increase
Solution Approach 1:
The patent pre-calculates and stores geometric data, mechanical properties, and interaction parameters for instruments and vessels before simulation begins. Material characteristics, structural configurations, and boundary conditions are defined in advance, allowing the simulation system to quickly retrieve and apply these parameters during real-time training sessions without intensive on-the-fly computations.
Solution Approach 2:
The patent uses parameter-based modeling where instrument and vessel properties are defined by adjustable parameters (dimensions, material properties, mechanical constants). By changing these parameters, the system can simulate different instrument types and vessel conditions without rebuilding entire models, reducing computational overhead while maintaining simulation fidelity.
