Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional manual assessment methods are used for joint replacement surgery planning, then the process is simpler and requires less computational resources, but the accuracy and precision of predicting the appropriate surgery type and implant selection is insufficient
Solution Approach 1:
The patent replaces manual mechanical assessment methods with an automated machine learning system that processes imaging data and patient information through computational algorithms. The machine learning model automatically predicts surgery type and implant specifications, substituting human manual evaluation with automated digital processing to improve accuracy while maintaining manageable system complexity through standardized computational approaches.
Solution Approach 2:
The system creates digital copies of patient anatomy through imaging data (X-rays, CT scans, MRI) and uses these digital representations to train and apply machine learning models. By working with digital copies rather than physical specimens, the system achieves high measurement precision through repeated automated analysis without increasing physical device complexity.
2Reliability
If comprehensive imaging data and patient information are analyzed using machine learning models, then the reliability of surgical procedure prediction is improved, but the loss of time for data processing and analysis increases
Solution Approach 1:
The system performs preliminary actions by pre-processing and normalizing patient data before the actual prediction task. Imaging data is pre-processed to extract relevant features, and patient information is normalized into standardized formats in advance. This preliminary preparation reduces the time required during the actual prediction process while maintaining high reliability through thorough data analysis.
Solution Approach 2:
The machine learning model performs self-service by automatically selecting and weighting relevant features from the comprehensive data set without requiring manual intervention. The system autonomously processes imaging data and patient information, identifying the most predictive features and generating surgery recommendations independently, which reduces both processing time and the need for extensive manual data curation.
3Manufacturing precision
If detailed anatomical parameters such as B-scores and C-scores are calculated from imaging data, then the manufacturing precision of implant selection is improved, but the difficulty of detecting and measuring these parameters increases
Solution Approach 1:
The system replaces manual measurement and calculation of anatomical parameters with automated image processing algorithms. The machine learning model automatically extracts B-scores, C-scores, and other anatomical measurements from imaging data through computational analysis, eliminating the need for manual measurement and reducing errors while improving the precision of implant selection.
Solution Approach 2:
The patent introduces an intermediary layer of automated image processing and feature extraction between the raw imaging data and the final implant selection. This intermediary system automatically calculates anatomical parameters, normalizes data, and prepares features for the prediction model, making the complex measurement tasks transparent and reducing the difficulty of parameter detection while maintaining high manufacturing precision.
