Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a standardized surgical guide is used for artificial joint replacement, then the manufacturing process is simple and cost-effective, but the accuracy of implant placement cannot be customized for individual patient anatomy
Solution Approach 1:
The surgical guide is divided into multiple components: a patient-specific base portion that interfaces with the patient's anatomy, and modular guide portions that can be attached and adjusted. This segmentation allows the guide to be customized for individual patient anatomy while maintaining manufacturing efficiency through standardized modular components.
Solution Approach 2:
Patient-specific anatomical data is collected and processed before surgery to create a customized guide design. The guide is designed and manufactured in advance based on pre-operative imaging and planning, allowing for precise customization without increasing intraoperative complexity.
2Manufacturing precision
If a patient-customized surgical guide is designed based on individual anatomy, then the accuracy of implant placement is improved, but the design process becomes complex and time-consuming
Solution Approach 1:
Patient-specific anatomical data is collected and processed before surgery to create a customized guide design. The guide is designed and manufactured in advance based on pre-operative imaging and planning, allowing for precise customization without increasing intraoperative complexity.
Solution Approach 2:
The surgical guide incorporates universal interface features and standardized components that can be adapted to different patient anatomies. This multi-functionality allows a single guide design platform to serve multiple customization needs, reducing overall design time while maintaining patient-specific accuracy.
3Reliability
If surgeon feedback is incorporated into the guide design process, then the suitability of the guide for actual surgery is improved, but the feedback exchange process increases complexity
Solution Approach 1:
The system incorporates structured feedback mechanisms where surgeons can provide input on guide design, fit, and functionality. This feedback is systematically collected and integrated into iterative design improvements, ensuring the guide meets practical surgical needs while maintaining a streamlined communication process between designers and surgeons.
