Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing training systems are used to simulate access site closure, then training effectiveness is improved, but system complexity and cost increase
Solution Approach 1:
The training system is divided into separate functional modules: a vascular model component, an anatomical simulant component, and a control assembly. This segmentation allows each module to be optimized independently and assembled only when needed, reducing overall system complexity while maintaining training effectiveness.
Solution Approach 2:
The vascular model is designed to simulate multiple vessel types (arterial and venous) using the same basic structure with adjustable parameters. The anatomical simulant can be configured to represent different tissue characteristics, allowing a single system to provide universal training for various closure procedures without requiring multiple specialized systems.
2Reliability
If existing training systems are used to simulate access site closure, then training realism is improved, but ease of operation deteriorates
Solution Approach 1:
The system incorporates dynamic elements including a pump that can simulate pulsatile arterial flow or steady venous flow by adjusting flow characteristics in real-time. The anatomical simulant can be dynamically adjusted to different tissue stiffness and permeability levels, allowing the system to adapt to different training scenarios while maintaining ease of operation through electronic control rather than manual adjustment.
Solution Approach 2:
The control assembly automatically manages the pump and anatomical simulant parameters based on pre-programmed scenarios or user selections, eliminating the need for manual adjustment of complex parameters. The system self-regulates flow rates, pressure, and tissue characteristics to match the selected training mode, simplifying operation while maintaining realism.
3Measurement precision
If existing training systems are used to simulate access site closure, then training accuracy is improved, but assembly difficulty increases
Solution Approach 1:
The system is manufactured as separate, pre-assembled modules (vascular model, anatomical simulant, control assembly) that can be independently produced and quality-tested. This segmentation simplifies the overall assembly process by reducing the complexity of building a single integrated system while maintaining the precision required for accurate training simulations.
Solution Approach 2:
Each module is pre-assembled, pre-tested, and pre-configured before final integration. The vascular model is pre-programmed with flow characteristics, the anatomical simulant is pre-positioned with accurate tissue properties, and the control assembly is pre-calibrated. This preliminary preparation ensures training accuracy is achieved without difficult assembly procedures, as modules are simply connected rather than built from scratch.
