Optical Identifier Layout for Verifying Substance Measuring Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing home monitoring systems for alcohol and drug addiction lack reliable methods to ensure that the substance measuring device is correctly assigned to the test subject, leading to potential manipulation and inefficiencies in monitoring.
Innovation Solution
A device with an optical identifier, such as a combination of barcodes, QR codes, or reflective foil sections arranged in a triangular pattern, is used to clearly and individually identify the substance measuring device, verifying its assignment to the test subject through image processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual photo review is used to verify device assignment, then verification capability is provided, but time consumption and complexity increase significantly
Solution Approach 1:
The patent replaces manual photo review with automated optical character recognition (OCR) technology to extract and verify device identifiers from images. This substitution of mechanical/manual verification with automated optical recognition systems dramatically reduces review time while maintaining verification reliability.
Solution Approach 2:
The system enables self-verification by automatically capturing images of the substance measuring device, extracting identifier information through OCR, and comparing it with registered device data without requiring manual intervention. The device and system work together to automatically verify assignment correctness.
2Reliability
If no device identification system is used, then system simplicity is maintained, but manipulation risk and monitoring reliability increase
Solution Approach 1:
The patent uses optical copies (images) of the substance measuring device to verify its identity and assignment. By capturing and analyzing visual representations of the device with its identifier, the system confirms device authenticity without requiring physical possession or complex hardware modifications to the measuring device itself.
Solution Approach 2:
The patent introduces an intermediary verification system that captures images of the device, extracts identifier information through OCR, and compares it with registered data. This intermediary layer acts as a mediator between the device and the monitoring system, providing verification without requiring direct physical interaction or complex integration with the substance measuring device.
3Productivity
If automated OCR verification is implemented, then verification speed and reliability improve, but system complexity and technical requirements increase
Solution Approach 1:
The patent replaces manual verification processes with automated optical character recognition technology. The OCR system automatically extracts text from images of the device identifier, enabling rapid verification without manual reading and comparison, thereby significantly increasing verification speed.
Solution Approach 2:
The system performs self-verification by automatically capturing images, extracting identifier information through OCR, and comparing it with registered device data without requiring manual intervention. This automation enables the system to verify device assignment independently and rapidly.
