Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual methods are used to manufacture customized arthroplasty jigs, then flexibility in customization is maintained, but labor intensity and operator error increase
Solution Approach 1:
The patent replaces manual mechanical manufacturing methods with an automated computer-controlled manufacturing system. The system uses image data from MRI or CT scans to automatically generate patient-specific resection guides, eliminating the need for manual measurement and fabrication while maintaining customization. This substitution reduces operator error and improves accuracy in implant alignment during arthroplasty procedures.
2Manufacturing precision
If automated image analysis is implemented to generate resection guides, then manufacturing precision and accuracy are improved, but device complexity and initial costs increase
Solution Approach 1:
The patent creates a digital copy of the patient's anatomy by importing image data from standard MRI or CT scans into a computer system. This digital model is then used to generate the patient-specific resection guide, eliminating the need for complex physical measurement devices. The copying approach maintains manufacturing precision while utilizing existing imaging infrastructure, thereby limiting the increase in device complexity.
3Device complexity
If traditional manual jig manufacturing is used, then equipment costs are lower, but time consumption and labor costs increase
Solution Approach 1:
The patent performs preliminary actions by generating the patient-specific resection guide before the actual arthroplasty procedure. The system imports image data, automatically processes it to create a 3D model, and generates the resection guide in advance. This preliminary digital fabrication eliminates time-consuming manual measurements and adjustments during surgery, significantly improving manufacturing efficiency without requiring complex equipment.

AI summary
A method of performing an arthroplasty procedure on a knee region of a femur of a patient where an implant is implanted on the knee region of the femur as part of the arthroplasty procedure is disclosed herein. The method may include generating a planned postoperative positional relationship of the implant relative to the femur. The method may also include, with the computerized representation of the implant in the planned postoperative positional relationship with the computerized representation of the knee region of the femur, generating a planned resection of the femur that will facilitate the implant being implanted on the knee region of the femur in the planned postoperative positional relationship. And the method may also include guiding an actual resection of the femur according to the planned resection of the femur.
