Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensors are integrated into the access device, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple sensors (flow meter and pressure sensor) into a single access device, integrating them within the elongate member structure. This merging approach allows simultaneous measurement of fluid flow and pressure without requiring separate devices, thereby improving overall measurement precision while managing complexity through unified design.
Solution Approach 2:
The access device is designed with multi-functionality, serving both as a physical access conduit and as a measurement platform. The elongate member simultaneously provides mechanical access and houses sensing capabilities, allowing the device to perform multiple functions (access, flow measurement, pressure measurement) thereby justifying the increased complexity through enhanced utility.
2Adaptability or versatility
If multiple lumens are included in the elongate member, then adaptability is improved, but device complexity increases
Solution Approach 1:
The elongate member is designed with multiple lumens (first lumen, second lumen, third lumen) each serving different functions - one for receiving secondary medical devices and others for fluid flow measurement. This multi-lumen configuration provides adaptability to handle various procedural needs simultaneously, making the device versatile enough to accommodate different medical interventions through a single access point.
Solution Approach 2:
The internal structure of the elongate member is segmented into multiple distinct lumens, allowing independent fluid pathways and device passage routes. This segmentation enables different functions to occur simultaneously within the same elongate member without interference, providing adaptability while maintaining organized structural complexity.
