Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If real-time glucose monitoring and dynamic therapy profile adjustments are implemented, then insulin therapy management is improved and glycemic control is enhanced, but device complexity and data processing requirements increase

Engineering Contradiction:

Improveinsulin therapy managementVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system segments the complex diabetes management functionality into distinct modules: glucose monitoring module, therapy profile management module, data processing module, and user interface module. This segmentation allows each module to handle specific tasks independently, improving overall system reliability while making the complexity more manageable and maintainable.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A processor acts as an intermediary between the glucose sensor and the user interface, mediating the complex data processing and therapy adjustment calculations. This intermediary handles the computational complexity internally while presenting simplified information and controls to the user, resolving the contradiction between advanced functionality and ease of use.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If continuous glucose tracking and real-time data processing are implemented, then therapy adjustments are optimized, but loss of time for data processing and system response increases

Engineering Contradiction:

Improvetherapy adjustment efficiencyVSAvoiddata processing time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The system performs preliminary processing of glucose data as it is collected, pre-calculating trend information and preparing therapy adjustment recommendations in advance. This preliminary action reduces the processing time required when actual therapy decisions need to be made, improving productivity without sacrificing real-time responsiveness.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The glucose monitoring and data processing operate continuously without interruption, maintaining a constant flow of information from sensor to therapy adjustment. This continuous operation eliminates gaps in data collection and processing, ensuring that therapy adjustments are based on the most current glucose levels while maintaining efficient system response.
