Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for measuring chemical components in breath are cumbersome, expensive, and limited to laboratory or clinical settings due to large equipment requirements and regulatory restrictions, making it difficult to measure breath analytes outside these environments.
Innovation Solution
A portable breath analysis system comprising a wireless transceiver, a mobile application, and a server system that implements a secure wireless pairing protocol between the device and a user's mobile device, allowing for authentication and data transmission without the need for user input, enabling easy pairing and secure communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a secure authentication system is implemented between portable device and mobile device, then device security and user authorization are improved, but pairing complexity and implementation difficulty increase
Solution Approach 1:
The patent uses the mobile device as an intermediary to facilitate secure pairing between the portable breath analysis device and the server. The mobile device acts as a trusted mediator that establishes secure credentials and enables authentication without requiring complex direct communication protocols between the portable device and server, thus improving security while managing complexity through the intermediary mobile device
Solution Approach 2:
The system performs preliminary authentication and credential establishment during the pairing phase before actual breath analysis operations. Security credentials are pre-established between the portable device and server through the mobile device intermediary, so that subsequent operations can proceed with already-validated security relationships, improving reliability without adding complexity to ongoing operations
2Reliability
If portable breath analysis device communicates directly with server system, then data security and traceability are improved, but device complexity and communication requirements increase
Solution Approach 1:
The mobile device serves as an intermediary that enables the portable breath analysis device to communicate with the server system without requiring the portable device to have direct, complex communication capabilities. The mobile device handles the complex server communication protocols while the portable device uses simpler wireless communication, thus improving data security through server integration while managing communication complexity through the intermediary
3Ease of operation
If wireless pairing protocol is implemented without user input, then ease of operation is improved, but security risks may increase
Solution Approach 1:
The system performs automatic authentication and pairing operations without requiring user input. The portable device and mobile device automatically exchange credentials and establish secure connections through pre-configured authentication mechanisms, improving ease of operation while maintaining security through automated verification processes that eliminate human error and intervention
Solution Approach 2:
Security credentials and authentication parameters are pre-established during device initialization and pairing setup. This preliminary security configuration enables subsequent automatic authentication operations to proceed without user input while maintaining strong security through pre-validated credentials, thus achieving both ease of operation and reliability

AI summary
A user device and a breath analysis device (or other types of portable devices) use a pairing and communication protocol that address user convenience and connectivity issues. For example, a breath analysis device is associated with a unique identifier and the unique identifier is associated with an account corresponding to the user. Likewise, a user device is associated with a user device identifier and the user device identifier is associated with the account corresponding to the user. The breath analysis device and the user device can use at least one of the identifiers to determine whether the user device is authorized to pair with the breath analysis device, and vice-versa. If authorized, the breath analysis device and user device can pair with one another. Once paired, the user device may wirelessly communicate with the breath analysis device for various purposes, such as to retrieve and display breath analysis test results.
