Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional fixed patient positioning systems are used, then device simplicity is maintained, but positioning flexibility and surgical access capability deteriorate
Solution Approach 1:
The patient positioning system is divided into multiple independently movable platforms (head platform, upper torso platform, lower torso platform, leg platforms) that can be adjusted separately. Each platform can be positioned independently in three dimensions, allowing flexible adaptation to various surgical requirements without requiring complete system redesign.
Solution Approach 2:
The system employs dynamically adjustable platforms with multiple degrees of freedom, allowing real-time repositioning during surgical procedures. The platforms can move in three dimensions and be oriented at various angles, providing adaptability for different surgical approaches while maintaining manageable complexity through modular design.
2Measurement precision
If manually adjusted positioning systems are used, then device complexity is reduced, but positioning precision and real-time adjustment capability deteriorate
Solution Approach 1:
The system incorporates sensors on each platform that detect position, orientation, and patient physiological parameters. This feedback is transmitted to a control system that can automatically adjust platform positions to maintain optimal alignment and respond to changes in patient condition, achieving high positioning precision through closed-loop control.
Solution Approach 2:
The positioning system includes automated adjustment mechanisms that use sensor data to self-correct positioning without constant manual intervention. The system can autonomously maintain optimal patient alignment and adjust for physiological changes, reducing the need for continuous manual calibration while maintaining high precision.
3Reliability
If simple positioning systems are used, then ease of operation is maintained, but surgical access capability and patient safety deteriorate
Solution Approach 1:
The positioning system is designed to support multiple surgical approaches and patient positions through its multi-functional platforms. The same system can accommodate anterior, posterior, and lateral surgical approaches by adjusting platform configurations, providing comprehensive safety coverage for various procedures without requiring multiple specialized devices.
Solution Approach 2:
The system incorporates intermediate control mechanisms and monitoring systems that mediate between the complex positioning capabilities and the surgeon's needs. Sensors, control systems, and user interfaces act as intermediaries that simplify operation while maintaining the sophisticated safety and positioning capabilities required for complex spinal surgeries.

AI summary
The present subject disclosure provides a novel system and method of maintaining a patient in an optimal position for spinal or other surgeries where the position of the patient and access to the surgical site may be very helpful. Further, neurophysiological data is obtained from the patient in real time through sensors on the patient contacting platforms and relayed to a system which determines whether the patient position should be moved to maintain optimal and viability health during the procedure.
