Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Prolonged insulin injection at a single location can lead to tissue damage and decreased diffusion characteristics, increasing the risk of skin pathologies such as infection, flare, skin injury, scarring, irritation, allergic reactions, abscess, amyloidosis, and hyperkeratosis, particularly due to improper site rotation in diabetes management.

Innovation Solution

A system and method that includes an application running on a device to track and manage insulin administration sites, providing visual indicators and notifications for site rotation, suggesting optimal sites based on historical usage and insulin diffusion sensitivity, and allowing for manual configuration and 3-dimensional modeling to ensure proper site rotation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If insulin injection or infusion is performed at a single location for an extended period, then treatment effectiveness is maintained, but tissue damage and skin pathologies occur

Engineering Contradiction:

Improvetreatment effectivenessVSAvoidtissue damage and skin pathologies

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent divides the abdomen into multiple discrete injection zones (e.g., upper left, upper right, lower left, lower right quadrants) and further segments each zone into multiple specific injection sites. This segmentation allows systematic rotation through different sites while maintaining treatment effectiveness and preventing tissue damage at any single location.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system pre-calculates and stores a rotation schedule of injection sites before actual use. The application pre-defines the sequence of sites to be used, ensuring that users rotate sites according to a predetermined plan that avoids tissue damage while maintaining treatment efficacy.

Inventive Principle:

Principle #10Preliminary action

2Object-affected harmful factors

If site rotation is implemented to prevent tissue damage, then skin pathology risk is reduced, but user compliance becomes more complex

Engineering Contradiction:

Improveskin pathology riskVSAvoiduser compliance

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The system automatically tracks which sites have been used and calculates the next available sites in the rotation sequence. The application self-manages the complexity of site rotation by maintaining usage records and providing real-time guidance, eliminating the need for users to manually track and calculate rotation schedules.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system provides real-time feedback to users about which sites are available for injection and which sites are currently unavailable due to recent use. The application displays visual indicators and notifications that guide users through the rotation process, making compliance intuitive and reducing the cognitive burden on users.

Inventive Principle:

Principle #23Feedback

3Measurement precision

If visual indicators and tracking systems are added to manage site rotation, then site rotation accuracy is improved, but device complexity increases

Engineering Contradiction:

Improvesite rotation accuracyVSAvoidsystem complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent integrates multiple functions into a single mobile application: site selection, usage tracking, rotation scheduling, visual indication, and educational content delivery. By consolidating these functions into one universal platform, the system achieves high site rotation accuracy without proportionally increasing overall system complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system replaces manual tracking methods (paper logs, mental calculation) with an electronic software-based tracking system. The mobile application uses digital data storage and processing to manage site rotation records, providing accurate tracking and visual indicators without requiring complex mechanical or physical tracking devices.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

An application running on a device to manage insulin site rotation may read a configuration file including a group, a plurality of sites in the group, and an image associated with the group. The application may detect an input selecting a site from the plurality of sites for administration of an insulin management device. The application may also set the selected site as unavailable for a predetermined duration in response to the input selecting the site. A log entry may be written to track usage of the site in response to the input selecting the site. A visual indicator on the selected site may show that the site is recently selected in response to detecting the input selecting the site within a predetermined duration. The insulin management device may be a pump, a syringe, or a glucose monitor.
