Problem

Existing vaccine and injectable medicine administration systems are inadequate for efficiently tracking and verifying vaccinations, particularly in developing countries, due to poor implementation, lack of skilled personnel, and inadequate tracking and management of injection administration.

Innovation Solution

The use of injectors equipped with unique identifiers, such as NFC chips, and an Injection Management App to facilitate electronic tracking, authorization, and verification of injection events, including a blockchain-based distributed network for security.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional manual tracking methods are used for vaccine administration, then implementation is simpler and requires fewer resources, but tracking precision and verification reliability are insufficient leading to poor management effectiveness

Engineering Contradiction:

Improvetracking reliabilityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces manual mechanical tracking methods with electronic/NFC-based automated tracking systems. Injectors contain NFC chips that automatically record and transmit administration data to centralized platforms, eliminating manual paper-based tracking and significantly improving reliability without requiring complex infrastructure

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The injector device performs self-tracking and self-reporting functions through integrated NFC chips and memory storage. The device automatically records administration events, patient information, and transmission data without requiring external manual intervention, enabling reliable tracking in resource-limited settings

Inventive Principle:

Principle #25Self-service

2Measurement precision

If electronic tracking systems with NFC chips are implemented, then tracking precision and verification capability are improved, but device complexity and implementation difficulty increase

Engineering Contradiction:

Improveinjection tracking precisionVSAvoidimplementation ease

Core Design Contradiction:

Measurement precisionVSEase of manufacture

Solution Approach 1:

The NFC-enabled injector serves multiple functions: it acts as both a medical delivery device and an electronic tracking terminal. The same NFC chip that identifies the injector also stores administration data, patient information, and transmission records, eliminating the need for separate tracking devices and simplifying implementation

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent merges the tracking functionality directly into the injector device by integrating NFC chips and memory storage within the injector itself. This combination of medical function and data tracking in a single device reduces overall system complexity while maintaining high tracking precision

Inventive Principle:

Principle #5Merging (Combining)

3Reliability

If centralized injection management platforms are deployed, then verification capability and disease prevention effectiveness are improved, but infrastructure requirements and resource demands increase

Engineering Contradiction:

Improveverification reliabilityVSAvoidinfrastructure resources

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The system implements partial centralization where essential verification functions are performed locally at the point of injection through NFC authentication, while comprehensive data management occurs centrally. This partial approach achieves sufficient verification reliability without requiring full centralized infrastructure in all settings

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The NFC chip acts as an intermediary that enables verification functionality in resource-limited settings. The chip stores essential authentication data locally, allowing verification to occur without constant connection to centralized servers, thus reducing infrastructure demands while maintaining reliability

Inventive Principle:

Principle #24Intermediary (Mediator)

4Loss of information

If injectors with data storage mechanisms are used, then information retention and tracking accuracy are improved, but device complexity and manufacturing cost increase

Engineering Contradiction:

Improveinformation retentionVSAvoidinjector complexity

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The data storage mechanisms (NFC chips and memory) are nested within the existing injector structure. The electronic components are integrated into the injector's housing and operational mechanism, adding information retention capability without significantly increasing overall device complexity or requiring separate external storage devices

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

Systems, methods and articles of manufacture provide for an injection management platform that allows the verification and management of injection event transactions involving injectors equipped with NFC or RFID chips utilizing a distributed and secure technology such as blockchain. An injection event transaction ledger allows for digital receipts of injection event transactions to be securely verified and updated. In accordance with some embodiments, injectors may comprise blow-fill-seal (BFS) injectors that are pre-filled with a single dose of a fluid agent comprising a vaccine or medicament, allowing for tracking of individual doses of the fluid agent via the injection event transaction ledger.
