Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensor cavities and signal transmitter cavities are integrated into the sensor head device, then measurement precision for blood temperature and ventricular pressure is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple sensor cavities and signal transmitter cavities into a single integrated sensor head device structure. The sensor carrying element houses both temperature sensors and pressure sensors within unified cavities, allowing simultaneous measurement of multiple physiological parameters without requiring separate discrete sensor assemblies, thereby reducing overall system complexity while maintaining high measurement precision.
Solution Approach 2:
The sensor head device is designed as a multi-functional unit that can simultaneously measure blood temperature, ventricular pressure, and other physiological parameters through integrated sensor cavities. This universal design allows a single device to perform multiple measurement functions that would otherwise require separate specialized devices, improving measurement precision while avoiding the complexity of coordinating multiple independent sensor systems.
2Ease of operation
If the sensor head device is designed as a plug-shaped package for minimally invasive insertion, then ease of operation is improved, but manufacturing precision requirements increase
Solution Approach 1:
The sensor head device is segmented into a distinct plug-shaped package that can be independently manufactured and then assembled to the catheter or delivery system. This segmentation allows the sensor head to be produced as a separate precision component with controlled tolerances, while the overall device benefits from modular assembly that reduces the precision requirements for the entire system. The plug shape enables standardized interfaces that simplify both insertion procedures and manufacturing processes.
3Reliability
If the sensor carrying element is encapsulated with silicone compounds, then reliability is improved through mechanical protection and biocompatibility, but manufacturing complexity increases
Solution Approach 1:
The sensor carrying element is encapsulated with silicone compounds to provide mechanical protection, biocompatibility, and chemical stability. This composite material approach combines the structural integrity of the sensor housing with the beneficial properties of silicone, creating a reliable sensor head device that can withstand the physiological environment. The silicone encapsulation protects the electronic components from damage while maintaining flexibility and biocompatibility, and this can be achieved through established manufacturing techniques that do not significantly increase overall device complexity.
