Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If cadaveric simulators are used, then anatomical accuracy is improved, but cost and availability deteriorate
Solution Approach 1:
The patent creates physical copies of anatomical structures using 3D printing technology. The system generates digital models from imaging data and produces tangible anatomical replicas that can be used for training, replacing the need for actual cadavers while maintaining anatomical accuracy.
Solution Approach 2:
The patent changes the physical state and material properties of anatomical structures by using different 3D printing materials and techniques. This allows the creation of tissue surrogates with varying degrees of realism and mechanical properties, enabling cost-effective alternatives to cadavers while preserving essential anatomical characteristics.
2Ease of manufacture
If virtual reality simulators are used, then cost and availability are improved, but anatomical accuracy and haptic interaction deteriorate
Solution Approach 1:
The patent merges virtual reality elements with physical models by integrating tracking markers and digital overlays onto tangible anatomical structures. This hybrid approach combines the cost-effectiveness of virtual technology with the anatomical accuracy of physical replicas, creating a enhanced training system that preserves both advantages.
3Ease of manufacture
If bench-top simulators are used, then cost is improved, but anatomical complexity deteriorates
Solution Approach 1:
The patent introduces articulation and movement capabilities to bench-top simulators by creating articulated anatomical models with movable joints and flexible components. This allows the simulators to dynamically replicate complex anatomical structures and their movements, significantly enhancing anatomical complexity while maintaining cost-effectiveness.
4Adaptability or versatility
If modular anatomical system with AR overlay is used, then flexibility and assessment capability are improved, but device complexity increases
Solution Approach 1:
The patent creates a universal training platform that can accommodate multiple anatomical structures, procedures, and assessment methods through a standardized modular system. The attachment mechanisms and marker systems are designed to work across different anatomical models and training scenarios, reducing overall system complexity despite the enhanced versatility.
