Solution Overview
Problem
Current drug detection technologies for fentanyl and its analogues are not field-deployable, costly, and unable to detect trace airborne levels or unprogrammed substances, posing safety risks for first responders due to their limitations in detecting mixed or adulterated drugs.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If laboratory-based analytical systems are used for drug detection, then detection accuracy is improved, but response time increases and field deployability is lost
Solution Approach 1:
The patent replaces complex laboratory-based analytical systems with a portable ion mobility spectrometer that uses ionization and electrical fields for drug detection. This substitution enables field-deployable, rapid detection while maintaining accuracy by using physics-based ion separation rather than laboratory instrumentation.
Solution Approach 2:
The invention changes the detection parameters by using ion mobility measurements in an electrical field rather than traditional laboratory analytical methods. This parameter change enables both rapid response (seconds) and maintained detection accuracy by measuring the mobility of ionized drug molecules through controlled electrical fields.
2Quantity of substance
If traditional detection devices are used, then bulk quantity testing is enabled, but trace airborne drug detection capability is lost
Solution Approach 1:
The patent extracts and detects trace airborne drug molecules by ionizing them and separating the ions based on their mobility in an electrical field. This extraction approach allows detection of trace quantities in air without requiring bulk samples, as the ion mobility spectrometer can detect and identify individual ionized drug molecules.
3Adaptability or versatility
If comprehensive drug library programming is implemented, then detection coverage is improved, but device complexity and cost increase
Solution Approach 1:
The patent implements a universal detection approach where the ion mobility spectrometer can detect multiple fentanyl analogues and other drugs using a single instrument configuration. The system's ability to measure ion mobility provides universal detection capability across different drug types without requiring separate programming for each substance, reducing complexity while maintaining versatility.
