Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for identifying allergic reactions are invasive, time-consuming, and often only detect reactions after they have occurred, making it difficult to administer timely treatment, especially for severe reactions.
Innovation Solution
A system comprising sensors to measure physiological parameters, a hardware processor to analyze these signals and user history, and a medication delivery device that can automatically administer medication in response to detected allergic reactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If blood tests or controlled exposure methods are used to identify allergic reactions, then identification accuracy is improved, but time consumption and invasiveness increase
Solution Approach 1:
The patent replaces invasive mechanical/biological testing methods (blood tests, controlled exposure) with optical sensing technology. The system uses optical sensors to detect physiological changes in real-time, substituting the need for time-consuming laboratory tests with immediate optical measurement of skin blood flow and other physiological parameters.
Solution Approach 2:
The system performs preliminary detection of allergic reactions by continuously monitoring physiological parameters before severe symptoms manifest. By detecting subtle changes in skin blood flow, temperature, and other physiological signals early in the allergic response process, the system enables intervention before the reaction escalates to severe stages.
2Measurement precision
If controlled exposure or elimination methods are used, then allergen identification is improved, but treatment timing deteriorates
Solution Approach 1:
The system implements continuous feedback monitoring of physiological parameters during allergen exposure. By real-time detection of allergic reaction indicators through optical sensing, the system provides immediate feedback that triggers alerts and treatment protocols, eliminating the delayed feedback inherent in traditional controlled exposure methods where reactions are only assessed after the exposure period ends.
Solution Approach 2:
The system takes preliminary action by detecting allergic reactions at their earliest stages, before severe symptoms develop. This early detection capability allows for immediate treatment administration, transforming the traditional approach where treatment occurs after severe reactions manifest into a proactive system that intervenes at the first signs of allergic response.
3Device complexity
If traditional observation methods are used, then system complexity is reduced, but detection capability deteriorates
Solution Approach 1:
The patent employs multi-functional optical sensors that can detect multiple physiological parameters simultaneously (skin blood flow, temperature, oxygen saturation, heart rate). This universal sensing approach allows a single device to perform comprehensive allergic reaction monitoring, replacing the need for multiple separate diagnostic tools while maintaining relatively simple system architecture.
Solution Approach 2:
The system enables self-monitoring and self-diagnosis of allergic reactions through automated optical detection and analysis. The device autonomously processes physiological data, compares it against baseline values, and generates alerts without requiring constant clinical intervention, thereby improving detection capability while keeping the system accessible and relatively simple to operate.

AI summary
A system which provides example systems and methods for tracking physiological measurements of a person, computing a ranking, and/or calling to action to teach the person about their food sensitivity and the severity of the sensitivity, as well as warn the person, offer alternate substitutions, or suggest ingredients to counter their reaction. One or more sensors may be configured to measure indications of allergic reactions in a patient's body. A hardware processor may be configured to receive measurements from the one or more sensors, determine a response action, and carry out the response action. The response action can include triggering an auto-injection of epinephrine.
