Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensor technologies are integrated in the head region of heart support systems, then measurement precision of body parameters is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple sensors (temperature sensor, pressure sensor) and signal transmitters into a single integrated sensor head device that is inserted into the head region of the heart support system. This merging approach enables precise measurement of multiple body parameters simultaneously while managing device complexity through unified integration rather than separate components.
Solution Approach 2:
The sensor head device is nested within the head region of the heart support system, with sensors and signal transmitters housed within the sensor head structure. This nesting arrangement allows the measurement components to be embedded within the existing system architecture, improving measurement precision without proportionally increasing overall device complexity.
2Adaptability or versatility
If multiple sensors and signal transmitters are integrated in the sensor head device, then functionality is improved, but manufacturing complexity increases
Solution Approach 1:
The sensor head device is designed as a separate, modular component that can be manufactured independently and then integrated into the heart support system. This segmentation allows for specialized manufacturing processes for the sensor head while keeping the overall system manufacturing manageable. The sensor head contains all necessary sensors and signal transmitters as integrated functional units.
Solution Approach 2:
The sensor head device serves multiple functions including temperature measurement, pressure measurement, and signal transmission, all within a single integrated component. This multi-functionality improves the versatility of the heart support system while avoiding the need to manufacture and assemble multiple separate components, thereby managing manufacturing complexity.
3Ease of operation
If the sensor head device is designed as a plug-shaped package, then ease of operation is improved, but device complexity increases
Solution Approach 1:
Instead of integrating sensors directly into the main body of the heart support system, the patent inverts the approach by creating a dedicated sensor head device that attaches to or is inserted into the system. This inversion simplifies the main system structure while concentrating sensing functionality in a separate, easily operable module with a plug-shaped design for straightforward insertion and removal.
