Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple sensors are located at different body sites for continuous monitoring, then comprehensive data for predicting hypo- and hyperglycemic events is achieved, but manufacturing complexity and user handling difficulty increase

Engineering Contradiction:
Improveprediction accuracyVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple sensors (glucose sensor, temperature sensor, motion sensor) that were previously located at different body sites into a single integrated sensor assembly. This merging maintains the comprehensive data collection capability for predicting hypo- and hyperglycemic events while reducing system complexity and improving ease of manufacture and user handling.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated sensor assembly serves multiple functions simultaneously: it monitors glucose levels, tracks temperature changes, detects motion patterns, and provides haptic feedback. This multi-functionality consolidates what previously required multiple separate devices, thereby reducing overall system complexity while maintaining comprehensive monitoring capabilities.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Loss of information

If multiple sensors are located at different body sites, then comprehensive data integration is achieved, but ease of manufacture and user handling deteriorate

Engineering Contradiction:
Improvedata integrationVSAvoidmanufacturing simplicity
Core Design Contradiction:
Loss of informationVSEase of manufacture

Solution Approach 1:

By merging multiple sensors into a single integrated assembly with a common substrate, the patent maintains comprehensive data integration capabilities while significantly simplifying the manufacturing process. The integrated design allows all sensors to be manufactured together as one unit rather than requiring separate manufacturing and assembly of multiple discrete components.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The sensor assembly is designed as a modular unit that can be independently manufactured and then integrated into the overall medical system. This segmentation allows for specialized manufacturing of the sensor component while maintaining ease of assembly into the final product, balancing manufacturing simplicity with data integration capabilities.

Inventive Principle:
Principle #1Segmentation

3Reliability

If multiple sensors are located at different body sites, then comprehensive monitoring is achieved, but ease of operation deteriorates

Engineering Contradiction:
Improvemonitoring completenessVSAvoiduser handling
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent merges multiple sensors into a single handheld applicator device, allowing users to apply comprehensive monitoring functionality with one device rather than managing multiple separate sensors at different body sites. This significantly improves ease of operation while maintaining complete monitoring capabilities through the integrated sensor array.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated sensor assembly includes an automated insertion mechanism that performs the insertion process itself once positioned on the skin. The system self-adjusts and self-positions the sensors during insertion, reducing the manual dexterity and complexity required from the user while ensuring proper placement for comprehensive monitoring.

Inventive Principle:
Principle #25Self-service
