Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If current surgical training systems are used, then specific surgical procedures can be simulated, but the systems lack portability and cannot facilitate training in different locations
Solution Approach 1:
The system is divided into separate portable modules: a mechanical interface unit with handles, a virtual reality headset with integrated cameras and sensors, and a computing device. Each component can be independently transported and assembled at different training locations, enabling mobility while maintaining full functionality.
Solution Approach 2:
The mechanical interface with handles simulates multiple surgical clamp operations, and the software supports various surgical scenarios. The same portable hardware setup can be used across different surgical training contexts, making the system universally applicable for diverse surgical procedure training without requiring location-specific equipment.
2Adaptability or versatility
If current surgical training systems are used, then motor skills for specific procedures can be trained, but the systems lack adaptability for diverse surgical scenarios
Solution Approach 1:
The mechanical interface incorporates handles that can simulate multiple types of surgical clamp maneuvers. The software platform supports various surgical scenarios and procedures, allowing the same physical device to adapt to different training needs through software configuration rather than requiring separate specialized equipment for each surgical type.
Solution Approach 2:
The system allows dynamic reconfiguration of training scenarios through software updates and scenario loading. The virtual surgical environments can be changed to represent different procedures, patient conditions, and surgical challenges, enabling the system to adapt to diverse surgical scenarios without physical modifications to the hardware.
3Reliability
If immersive virtual reality simulation is implemented, then motor skills and clinical decision-making can be improved, but the system requires complex mechanical and electronic configurations
Solution Approach 1:
The system replaces complex mechanical simulation equipment with a virtual reality-based approach. Instead of using elaborate mechanical models of surgical instruments and anatomical structures, the invention uses virtual representations rendered by software, controlled through simpler handheld interfaces that track movement via cameras and sensors rather than complex mechanical linkages.
Solution Approach 2:
The system creates virtual copies of surgical instruments, anatomical structures, and surgical procedures through 3D modeling and rendering. These digital replicas provide realistic training experiences without requiring physical models, reducing the mechanical complexity while maintaining training fidelity. The virtual environments can be precisely replicated and consistently reproduced across different training sessions.
