Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional IV catheter systems are used without monitoring devices, then the device complexity is low and ease of operation is high, but reliability is poor due to inability to detect complications early
Solution Approach 1:
The monitoring system is divided into separate functional modules: stabilization platform, sensor module (with temperature and optical sensors), transceiver, and processing unit. This segmentation allows each component to perform its specific function independently, improving reliability while keeping the overall system manageable in complexity
Solution Approach 2:
The stabilization platform serves multiple functions: it stabilizes the IV catheter position, houses the sensor module, and provides a interface for data collection. This multi-functionality reduces the need for separate devices, thereby improving detection reliability without proportionally increasing system complexity
2Measurement precision
If continuous monitoring with multiple sensors is implemented, then detection precision is improved, but device complexity increases
Solution Approach 1:
The temperature sensor and optical sensor are merged into a single sensor module that is integrated with the stabilization platform. This combining approach allows simultaneous measurement of multiple physical characteristics (temperature and optical properties) with high precision while avoiding the complexity of having separate monitoring systems
Solution Approach 2:
The processing unit acts as an intermediary that receives data from both sensors, compares temperature differences, and processes optical signals to detect infiltration. This intermediary component coordinates the multiple sensors, enabling precise measurement without requiring complex direct interactions between sensors themselves
3Ease of operation
If remote data transmission is added, then ease of operation is improved through remote monitoring, but device complexity increases due to additional components
Solution Approach 1:
The transceiver automatically transmits monitoring data to remote locations without requiring manual intervention. The system self-services the data transmission function, improving ease of operation through remote monitoring while the automated nature of the process minimizes the operational complexity burden on users
4Reliability
If multiple sensors are used to detect different complications, then reliability is improved, but the device becomes more complex
Solution Approach 1:
Different sensors are positioned at specific locations within the stabilization platform to detect different types of complications: temperature sensors detect infiltration and phlebitis, while optical sensors detect tissue changes. This localized placement of sensors with specific detection qualities improves reliability by targeting specific detection functions to appropriate locations without requiring all sensors to be complex
