Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current medical practices rely on empirical data and invasive procedures for diagnosis and treatment, then treatment protocols can be established based on accumulated experience, but comprehensive theoretical understanding of tumor mechanisms is lacking
Solution Approach 1:
The patent performs preliminary computational simulations of tumor growth and treatment responses before actual clinical intervention. By using patient-specific geometric models and reaction-diffusion equations to predict tumor evolution and PSA dynamics in advance, the system allows clinicians to evaluate multiple treatment scenarios virtually, reducing reliance on empirical trial-and-error approaches while maintaining treatment reliability.
2Measurement precision
If regular screening and biopsy procedures are used for early detection, then cancer can be detected at earlier stages, but invasive procedures increase patient burden and risk
Solution Approach 1:
The patent creates a virtual copy of the patient's prostate anatomy using medical imaging data to generate a patient-specific geometric model. This digital twin allows for non-invasive simulation of tumor growth patterns and treatment responses, enabling accurate cancer detection and treatment planning without requiring invasive biopsy procedures, thereby maintaining detection precision while eliminating procedural harm.
Solution Approach 2:
The patent replaces mechanical invasive biopsy procedures with computational simulations based on reaction-diffusion equations. By substituting physical needle insertion with virtual modeling of tumor dynamics and PSA secretion, the system achieves equivalent or superior diagnostic accuracy without the harmful effects of invasive procedures.
3Adaptability or versatility
If patient-specific geometric models and reaction-diffusion equations are used to simulate tumor evolution, then customized treatment planning is enabled, but computational complexity increases
Solution Approach 1:
The patent develops a universal computational framework that can simulate multiple aspects of prostate cancer including tumor growth, invasion patterns, and PSA dynamics using the same patient-specific geometric model and reaction-diffusion equations. This multi-functional simulation system handles various treatment scenarios (surgery, radiation, hormone therapy) within a single integrated platform, reducing overall system complexity while maintaining high adaptability for customized treatment planning.
