Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If current manual methods are used for fitting bone implants, then the process is simple to perform, but the precision and accuracy of implant fitting deteriorates
Solution Approach 1:
The patent creates a virtual three-dimensional copy of the patient's bone anatomy using imaging data (CT or MRI scans). This digital replica allows for precise measurement, planning, and simulation of implant placement without physically manipulating the actual bone, thereby achieving high fitting precision while keeping the physical intervention minimal.
Solution Approach 2:
The patent replaces manual mechanical measurement and fitting methods with computer-based digital modeling and virtual surgical planning software. This substitution of mechanical processes with computational methods enables precise control over implant dimensions and positioning, significantly improving fitting accuracy.
2Manufacturing precision
If custom-designed bone implants are manufactured for each patient, then the fitting accuracy improves, but the manufacturing time and complexity increases
Solution Approach 1:
The patent performs all design measurements, virtual trial placements, and implant customization in advance during a pre-surgical planning phase. By completing the design work before the actual surgery, the system eliminates time-consuming adjustments during the surgical procedure itself, thereby reducing overall treatment time while maintaining high precision.
Solution Approach 2:
The patent allows for rapid modification of implant parameters (dimensions, shape, positioning) through software control rather than physical rework. This digital parameter adjustment capability enables quick iterations and optimizations of the implant design without adding significant manufacturing time, as changes can be made and visualized instantly in the virtual model.

AI summary
An anatomical implant application, such as a bone implant application for instance, can receive an anatomical image that is representative of an anatomical structure. The anatomical implant application can generate an implant image that is associated with the anatomical structure. The generated implant image can define an inner surface that faces the anatomical image. A plurality of distances can be determined from respective locations of the inner surface of the implant image to the anatomical image in respective straight lines. The distances may represent a superimposition of the implant image over the anatomical image. The distances may be compared to a tolerance. The inner surface may be repositioned so as to change at least the select one of the distances. An implant, such as a bone implant for instance, may be fabricated in accordance with data that is associated with the implant image.
