Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional imaging methods are used during neurosurgery, then imaging data can be obtained, but tissue damage and procedural complexity increase
Solution Approach 1:
The imaging device is nested within the access port structure, with the imaging probe contained inside the access port body. This allows the imaging device to be inserted through the same surgical access point without requiring additional incisions or disturbing internal tissues, thereby maintaining high imaging resolution while minimizing tissue damage.
Solution Approach 2:
The access port is designed to serve multiple functions: providing surgical access and simultaneously housing an integrated imaging device. This multi-functional design eliminates the need for separate imaging equipment, reducing procedural complexity and tissue disturbance while maintaining imaging capabilities.
2Adaptability or versatility
If multiple imaging modalities are integrated, then imaging versatility improves, but device complexity increases
Solution Approach 1:
The imaging device is divided into separate functional modules (MRI coil, ultrasound transducer, optical imaging components) that can be independently selected and configured. Each module can be activated based on surgical needs, providing imaging versatility while keeping the overall device structure manageable through modular design.
Solution Approach 2:
The device incorporates dynamic switching capabilities that allow different imaging modalities to be activated or deactivated based on real-time surgical requirements. This dynamic configuration enables versatile imaging options without requiring all imaging components to be permanently active, thereby managing device complexity.
3Measurement precision
If imaging device is inserted into access port, then imaging precision improves, but risk of tissue disturbance increases
Solution Approach 1:
The imaging device is pre-integrated into the access port structure before surgical insertion. This preliminary integration ensures that the imaging device and access port move as a single unit, eliminating the need for separate insertion of the imaging probe and thereby preventing tissue disturbance that would occur with sequential insertion.
Solution Approach 2:
The access port serves as an intermediary structure that facilitates the safe insertion and positioning of the imaging device. By providing a pre-formed pathway and housing, the access port mediates the interaction between the imaging device and internal tissues, ensuring the imaging device can achieve precise positioning without directly disturbing tissues during insertion.
