Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional surgical methods are used without preoperative simulation, then the surgical process is simple and quick, but the success rate of surgery decreases and user satisfaction deteriorates due to unfavorable postoperative prognosis
Solution Approach 1:
The system performs preoperative simulation of cervical artificial disc movement before actual surgery. It estimates landmarks from medical images, generates available space models, designs customized disc models, and simulates their movement to predict postoperative outcomes, allowing surgeons to optimize surgical plans in advance
Solution Approach 2:
The system creates a virtual copy of the patient's cervical spine anatomy by estimating landmarks from medical images and generating a three-dimensional model of the available space. This virtual model replicates the patient's unique anatomical structure, allowing for customized disc design and movement simulation without physical intervention
2Manufacturing precision
If customized cervical artificial discs are designed based on individual anatomical conditions, then surgical outcomes improve, but the manufacturing process becomes more complex
Solution Approach 1:
The system determines optimal disc parameters (size, shape, curvature) by simulating movement in the generated available space. It adjusts disc specifications based on simulated performance metrics such as range of motion, stability, and fit within the patient's unique anatomical boundaries, optimizing the balance between customization and manufacturability
3Reliability
If preoperative simulation and customization processes are implemented, then surgical success rate increases, but the time required for surgical preparation increases
Solution Approach 1:
The system replaces time-consuming manual measurement and planning processes with automated computer-based algorithms. It automatically estimates landmarks from medical images, generates three-dimensional available space models, designs optimized disc models, and performs movement simulations, significantly reducing preoperative preparation time while improving accuracy
