Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional manufacturing methods are used for cardiovascular devices, then manufacturing constraints are maintained, but the devices fail to fit patient-specific anatomies and have reduced operability
Solution Approach 1:
The patent applies parameter changes by transitioning from conventional manufacturing parameters to additive manufacturing parameters, enabling customization of device geometry, size, and micro-features while maintaining manufacturing feasibility through digital model adjustment and iterative optimization
Solution Approach 2:
The patent uses copying by creating patient-specific 3D digital models from medical imaging data (CT or MRI scans), which serve as precise templates for manufacturing custom devices that replicate the patient's unique anatomy without requiring complex manual fabrication
2Manufacturing precision
If conventional cardiovascular devices are designed, then general applicability is maintained, but they cannot account for patient-specific morphologies
Solution Approach 1:
The patent applies preliminary action by performing patient-specific 3D modeling and digital prototyping before actual device manufacturing, allowing precise anatomical fitting to be achieved through pre-planning and simulation, thereby reducing the complexity of the physical manufacturing process
Solution Approach 2:
The patent utilizes another dimension by transitioning from 2D medical imaging data to 3D patient-specific models, enabling comprehensive anatomical representation and precise device customization that accounts for complex spatial relationships in patient morphology
3Reliability
If customized devices are manufactured using additive manufacturing, then patient-specific fit is achieved, but manufacturing process complexity increases
Solution Approach 1:
The patent applies universality by using a single additive manufacturing platform that can produce various types of cardiovascular devices (stents, grafts, valves) with different geometries and features, thereby managing manufacturing complexity through a unified process rather than multiple specialized manufacturing lines
