Engineering Contradiction Analysis
1Reliability
If current technologies are used to identify implant geometries and positions, then the procedure can be performed with available tools, but the optimal joint function cannot be achieved due to limited size options and joint complexities
Solution Approach 1:
The patent applies parameter changes by transitioning from discrete, limited implant size options to continuous, customizable implant parameters. The system allows modification of implant geometry, size, and position parameters to precisely match patient-specific joint characteristics, thereby achieving optimal joint function while overcoming the limitation of fixed size options in conventional implants
Solution Approach 2:
The patent implements preliminary action by performing pre-operative planning and optimization calculations before the actual implantation procedure. The system uses patient-specific joint data to determine optimal implant parameters in advance, allowing surgeons to proceed with precisely tailored implants rather than selecting from limited pre-fabricated size options during surgery
2Manufacturing precision
If patient-specific optimization is performed, then anatomic and biomechanic fit is improved, but the complexity of the procedure increases
Solution Approach 1:
The patent replaces manual trial-and-fit mechanical procedures with computer-based optimization algorithms. The system uses computational methods to calculate optimal implant parameters based on patient-specific data, substituting complex manual measurement and adjustment processes with automated digital planning and precision manufacturing
Solution Approach 2:
The patent creates precise digital copies of patient-specific joint anatomy through imaging and modeling. These digital replicas serve as the basis for optimization calculations, allowing virtual testing and refinement of implant parameters before actual implantation, thereby achieving high precision without proportionally increasing physical procedure complexity
