Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If invasive blood collection methods are used for physiological parameter monitoring, then measurement precision is improved, but patient discomfort increases and real-time monitoring capability deteriorates
Solution Approach 1:
The invention extracts the sensor element from the traditional invasive blood collection process, placing it in subcutaneous tissue to continuously sample interstitial fluid. This allows physiological parameters to be measured without repeated finger pricks, eliminating patient discomfort while maintaining measurement precision through continuous real-time monitoring of glucose and other analytes in the interstitial fluid.
Solution Approach 2:
The invention uses interstitial fluid as an intermediary medium between blood and the external environment. By measuring analytes in the interstitial fluid that correlates with blood glucose levels, the system achieves accurate physiological monitoring without direct blood collection, thereby improving patient comfort while maintaining measurement precision.
2Duration of action of stationary object
If small sensing elements are implanted in subcutaneous tissue for long-term monitoring, then real-time physiological data monitoring is improved, but device complexity increases
Solution Approach 1:
The device is segmented into distinct functional modules: a sensor element for analyte detection, a holder for securing the sensor, a waterproof seal for protection, and a transmitter for data communication. This modular segmentation allows each component to be optimized independently while working together to achieve long-term implantation with manageable overall complexity.
Solution Approach 2:
The holder structure serves multiple functions simultaneously: it secures the sensor element in place, provides a pathway for analyte diffusion to the sensor, incorporates waterproof sealing to protect internal components, and enables long-term stability in subcutaneous tissue. This multi-functionality reduces the need for separate components, thereby managing device complexity while achieving long-term implantation durability.
3Reliability
If a waterproof seal is added to prevent external liquid ingress, then reliability is improved, but device complexity increases
Solution Approach 1:
The waterproof sealing function is merged with the holder structure itself rather than being a separate component. The holder is designed with integrated sealing features that prevent external liquid ingress while maintaining the structural integrity and simplicity of the overall device, thereby improving reliability without significantly increasing device complexity.
