Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual calculation of insulin doses is performed by the patient, then the patient can determine insulin requirements based on blood glucose levels, meal intake, and physical activity, but the cognitive burden increases and errors in dosing occur
Solution Approach 1:
The system enables self-service by automatically calculating insulin doses based on data collected from sensors and user inputs. The processor computes the required insulin amount using stored algorithms and parameters, eliminating the need for manual calculations by the patient while maintaining dosing accuracy.
Solution Approach 2:
The patent replaces the mechanical cognitive process of manual calculation with an electronic computing system. The processor automatically performs dose calculations by integrating data from blood glucose sensors, meal intake tracking, and physical activity monitors, substituting human cognitive effort with automated computational processing.
2Measurement precision
If complex therapy management systems are implemented to assist insulin dosing, then dosing accuracy improves, but the device complexity increases
Solution Approach 1:
The system achieves multi-functionality by integrating multiple capabilities into a single platform: blood glucose monitoring, meal intake tracking, physical activity sensing, insulin dose calculation, and recommendation generation. This universal approach improves dosing accuracy while managing complexity through consolidation rather than proliferation of separate devices.
Solution Approach 2:
The patent combines data collection, processing, and decision-support functions into an integrated system. The processor merges inputs from multiple sensors and user inputs, applies therapeutic algorithms, and generates dosing recommendations in a unified workflow, reducing the complexity that would arise from separate standalone components.
3Reliability
If real-time monitoring and therapy recommendations are provided, then glycemic control improves, but the use of energy and computational resources increases
Solution Approach 1:
The system implements periodic monitoring and recommendation generation rather than continuous operation. The processor calculates insulin doses at specific intervals based on blood glucose measurements, meal inputs, and activity data, reducing energy consumption while maintaining reliable glycemic control through timely updates.
Solution Approach 2:
The system performs preliminary calculations by pre-storing therapeutic parameters, algorithms, and reference data in memory. When a measurement is taken, the processor quickly retrieves pre-configured parameters and performs calculations based on current inputs, reducing real-time computational energy requirements while maintaining control reliability.
