Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If healthcare professionals manually determine therapy regimens through infrequent visits, then patient compliance monitoring is difficult, but the system complexity and cost increase
Solution Approach 1:
The system enables self-service by automatically collecting glucose data from continuous monitoring devices, calculating insulin dosages using embedded algorithms, and generating compliance reports without requiring healthcare professional intervention for each adjustment. The processor autonomously performs data analysis and dosage optimization that previously required manual clinical assessment.
Solution Approach 2:
The system implements continuous feedback loops where glucose data is constantly monitored, compared against target ranges, and used to automatically adjust insulin dosage recommendations. Compliance data is also fed back into the system to verify whether recommended dosages were administered, creating a closed-loop control system that improves glucose management through iterative adjustment.
2Productivity
If continuous glucose data is used for frequent titration adjustments, then glucose control improves, but data processing complexity increases
Solution Approach 1:
The system replaces manual mechanical processes of data collection, analysis, and dosage calculation with automated electronic processing. The processor automatically ingests continuous glucose data streams, applies clinical algorithms, and generates dosage recommendations without requiring manual data entry or analysis by healthcare professionals, thereby increasing titration frequency while managing processing complexity through automation.
Solution Approach 2:
The system changes the parameter of data processing from manual batch processing to automated continuous processing. By implementing real-time algorithms that continuously analyze glucose readings and automatically adjust dosage parameters, the system achieves high-frequency titration adjustments without proportionally increasing operational complexity, as the processing is handled autonomously by the system.
3Measurement precision
If compliance monitoring is implemented, then non-compliance detection improves, but system complexity increases
Solution Approach 1:
The system merges compliance monitoring functionality with the existing glucose data collection and dosage recommendation features. By combining these functions into a single integrated system where the same processor handles both glucose analysis and compliance verification, the system achieves accurate compliance detection without proportionally increasing overall system complexity, as shared hardware and software resources are utilized.

AI summary
A system for titrating a basal insulin dose that includes a glucose monitoring device configured to collect glucose data of a user, processors in communication with the glucose monitoring device, and a memory coupled to the processors. The processors are configured to determine an initial basal insulin dose, receive insulin data and glucose data during a titration period. The validity of each day is assessed, and a titration glucose level is determined for each valid day. The titration glucose level for each day is compared to glucose level thresholds, and a recommended adjustment to the basal insulin dose is determined based on the comparison.
