Tracking Vehicle Immunization Record Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In regions with frequent population movement, the recording of births and immunizations is challenging due to the lack of reliable birth certificates and vaccination records, leading to misallocation of resources, redundant vaccinations, and inaccurate immunization coverage estimates, exacerbated by the high cost and inaccuracy of paper-based data processing.
Innovation Solution
A system utilizing tracking vehicles that store immunization data and unique identifiers, allowing clinics to read and update records without server connectivity, with the ability to connect to a network when available, and incorporating financial incentives for caregivers to encourage immunization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If paper-based records are used for immunization tracking, then the system is simple to implement, but the accuracy and reliability of data deteriorates due to inaccuracy and loss
Solution Approach 1:
The patent uses electronic copies of immunization records stored on tracking vehicles (mobile devices) and terminals instead of paper-based records. The electronic processor creates and maintains digital copies of user records, which can be updated and synchronized across multiple devices, eliminating the inaccuracies and losses associated with paper records while maintaining system accessibility.
Solution Approach 2:
The patent replaces the mechanical paper-based record-keeping system with an electronic digital system. The electronic processor, memory, and communication interfaces substitute for physical paper files, manual filing, and physical record transfer, thereby improving reliability through digital storage and reducing errors from manual handling.
2Reliability
If clinics require server connectivity to access immunization records, then centralized data management is improved, but accessibility in remote areas deteriorates due to lack of connectivity
Solution Approach 1:
The patent divides the centralized record-keeping system into distributed segments. Each tracking vehicle and terminal stores local copies of user records, allowing clinics to access and update immunization data without requiring continuous server connectivity. The system segments the data storage function across multiple independent devices that can operate autonomously.
Solution Approach 2:
The patent implements preliminary data caching on tracking vehicles and terminals before connectivity is needed. User records are stored locally in advance, allowing clinics to access and update immunization data offline. When connectivity becomes available, the electronic processor automatically synchronizes changes with the server, ensuring data consistency without requiring continuous connection.
3Reliability
If caregivers must travel to immunization centers multiple times, then complete immunization coverage can be achieved, but the cost and time burden increases leading to high dropout rates
Solution Approach 1:
The patent enables caregivers to access and manage immunization records themselves through tracking vehicles. The system allows self-service functionality where caregivers can view vaccination history, check upcoming due dates, and receive notifications without requiring multiple trips to clinics, reducing time and transportation costs while maintaining coverage tracking.
Solution Approach 2:
The patent implements feedback mechanisms where the system automatically notifies caregivers about upcoming immunization due dates and vaccination status. The electronic processor monitors record data and provides timely alerts, enabling caregivers to plan visits efficiently and reducing unnecessary travel while ensuring complete immunization coverage is achieved.
4Adaptability or versatility
If population movement is frequent, then people have greater mobility freedom, but the accuracy of immunization coverage estimates deteriorates due to difficulty in tracking
Solution Approach 1:
The patent creates portable electronic copies of immunization records on tracking vehicles that move with individuals. Instead of relying on fixed-location paper records that become obsolete with population movement, the system distributes digital record copies to mobile devices, ensuring accurate tracking of immunization status regardless of location changes.
Solution Approach 2:
The patent pre-loads immunization record data onto tracking vehicles before population movement occurs. The electronic processor stores complete user records locally, allowing accurate tracking of immunization coverage even when individuals move frequently. The system proactively updates and synchronizes records in advance, maintaining measurement precision despite mobility.
Data Source
AI summary
A system for maintaining individual immunization records. The system includes a tracking vehicle storing a first instance of a user record a terminal including an electronic processor and a memory. The electronic processor is configured to communicate with the tracking vehicle, obtain a second instance of the user record stored in the memory of the terminal and determine whether immunization data in the first instance or the second instance is more recent. When the first instance of the user record from the tracking vehicle includes more recent immunization data than the second instance of the user record stored in the memory, the electronic processor is configured to update the user record stored in the memory of the terminal with the more recent immunization data in the first instance of the user record of the tracking vehicle.
