Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no standard method to disseminate the vehicle interior air quality status to various stakeholders, posing a concern for the transmission of airborne micro-particles such as viral and bacterial pathogens in shared vehicle services, and existing solutions lack a reliable tracking mechanism.
Innovation Solution
Integration of a pathogen detector within vehicles that uses Blockchain technology to issue a vehicle health pass credential, allowing continuous air quality monitoring, automatic detection of pathogens, and self-sanitization or routing to cleaning facilities, with transparent and tamper-resistant digital credentials for stakeholders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pathogen detection and air quality monitoring are implemented in shared vehicles, then health safety and reliability are improved, but device complexity and cost increase
Solution Approach 1:
The system segments health tracking into vehicle-level and individual-level components. Vehicles have pathogen detectors and air quality monitors that report to a blockchain ledger, while individuals have mobile apps that query and display relevant health information. This segmentation allows the complex system to be built from modular, independently manageable components.
Solution Approach 2:
A blockchain-based distributed ledger serves as an intermediary layer between pathogen detection devices and user interfaces. The blockchain smart contracts process and verify health data automatically, eliminating the need for complex centralized servers and reducing overall system complexity while maintaining reliability.
2Measurement precision
If continuous air quality monitoring and pathogen detection are performed, then measurement precision and reliability are improved, but energy consumption increases
Solution Approach 1:
The system implements periodic air quality monitoring rather than continuous monitoring. Pathogen detectors and air quality sensors take measurements at scheduled intervals (e.g., after each ride or at predetermined time intervals), reducing energy consumption while maintaining sufficient measurement precision for health safety assessment.
Solution Approach 2:
The system performs comprehensive pathogen detection and air quality analysis only when necessary (e.g., when a ride is completed or when quality thresholds are approached), rather than continuously. This partial action approach maintains measurement precision for critical decisions while minimizing unnecessary energy expenditure during normal operation.
3Reliability
If blockchain technology is used for health pass credentials, then data integrity and trust are improved, but computational overhead and processing time increase
Solution Approach 1:
Vehicle health pass credentials are generated and stored on the blockchain in advance, before they are needed for verification. When a ride is requested or completed, the system simply queries the pre-existing blockchain record rather than performing complex real-time analysis, dramatically reducing verification time while maintaining data integrity through blockchain's immutable nature.
Solution Approach 2:
The system uses blockchain to create and store digital copies of vehicle health certificates and air quality data. These immutable digital copies can be quickly queried and verified by multiple users simultaneously without affecting the original data or requiring complex computational verification, thus reducing processing time while maintaining integrity.
4Reliability
If transparent and tamper-resistant digital credentials are implemented, then information security and trust are improved, but device complexity and implementation difficulty increase
Solution Approach 1:
The blockchain-based credential system serves multiple functions: it stores vehicle health data, verifies air quality measurements, issues health pass certificates, and provides audit trails for regulatory compliance. This multi-functionality reduces the need for separate systems for each function, simplifying overall implementation while maintaining high security and transparency through blockchain's inherent properties.

AI summary
This disclosure describes systems and methods using blockchain for in-vehicle health and wellness tracking. An example method may include receiving a request for a vehicle from a mobile device of a user. The example method may also include receiving, from a pathogen detector device within a first vehicle, an indication that a number of pathogens within the first vehicle is less than a threshold amount. The example method may also include assigning the first vehicle to the user based on the indication that the number of pathogens within the first vehicle is less than a threshold amount.
