Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If electrochemical sensors are directly implanted into blood vessels or subcutaneous tissues, then glucose detection capability is improved, but device weight and volume increase, and patient mobility is restricted
Solution Approach 1:
The device is divided into two independent parts: a lightweight disposable probe assembly containing the glucolase micro electrode needles for glucose detection, and a separate portable host containing the circuit boards and processing units. This segmentation allows the sensing function to be separated from the heavy electronics, enabling continuous monitoring without the burden of heavy implanted sensors.
Solution Approach 2:
The probe assembly with glucolase micro electrode needles is designed as a disposable component that can be used for continuous glucose monitoring for up to 7 days and then discarded. This eliminates the need for permanent implantation of heavy sensors and allows patients to avoid long-term presence of bulky devices in their bodies.
2Reliability
If sensor guiding objects with cables and wires are placed on the skin, then signal transmission is achieved, but patient mobility is limited and the device becomes heavy and inflexible
Solution Approach 1:
The cable and wire connections are completely removed from the system. The probe assembly communicates with the portable host through wireless Bluetooth technology, eliminating the physical constraints of cables and wires that previously limited patient mobility and made the device inflexible.
Solution Approach 2:
The mechanical connection system (cables and wires) is replaced with a wireless electromagnetic communication system. The portable host and probe assembly exchange data via Bluetooth wireless technology, allowing patients to move freely without being tethered to any device.
3Quantity of substance
If multiple blood glucose papers are used for dynamic monitoring, then blood glucose data can be collected, but the user experiences repeated stabbing pains and poor user experience
Solution Approach 1:
The glucolase micro electrode needles in the probe assembly enable continuous glucose monitoring by constantly detecting glucose levels in the interstitial fluid. This eliminates the need for repeated discrete blood sampling and skin piercings, providing uninterrupted glucose data without repeated pain to the user.
Solution Approach 2:
The monitoring method transitions from discrete blood sampling (requiring multiple piercings) to continuous interstitial fluid detection. The glucolase micro electrode needles detect glucose in the interstitial fluid, which continuously bathes the needles, providing ongoing data without the need for repeated invasive sampling.
4Stability of the object's composition
If sensor guiding objects are bound on the body, then secure positioning is achieved, but the device becomes heavy and cannot be moved freely
Solution Approach 1:
The system is segmented into a lightweight disposable probe assembly that adheres to the skin for stable positioning, and a separate portable host that can be freely carried. The probe assembly weighs minimal amount and can be moved to different body locations, while the host contains the heavier electronics and can be carried in a pocket or bag.
