Solution Overview

Problem

Existing vital data measurement systems are susceptible to improper replacement, where a third party's data is used instead of the user's, as personal authentication methods are not robust enough to prevent unauthorized use of measurement devices.

Innovation Solution

A vital-data measurement controller that uses image processing to authenticate the user and the measurement device based on positional relationships in captured images, ensuring the device is worn by the user during the measurement process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If face recognition based on captured image data is used for personal authentication, then the likelihood of unauthorized measurement can be reduced, but improper replacement of vital data by a third party wearing the measurement device remains possible

Engineering Contradiction:

Improveauthentication reliabilityVSAvoidmeasurement system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces image processing technology as an intermediary between the user and the measurement device. The image processor analyzes captured images to detect whether the measurement device is properly worn on the user's body, creating an additional verification layer that prevents third-party data replacement while maintaining system reliability

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces traditional mechanical or manual verification methods with automated image processing and computer vision algorithms. The system uses captured images and automated analysis to verify device-wearing status, eliminating the need for complex manual authentication procedures while enhancing security

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If pulse count analysis from image data is used to verify user identity during blood pressure measurement, then data authenticity can be confirmed, but this method cannot be applied to other vital data measurements

Engineering Contradiction:

Improvedata authenticityVSAvoidmeasurement method applicability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent develops a universal image processing-based verification method that can be applied across multiple types of vital data measurements. Instead of relying on pulse count analysis specific to blood pressure measurement, the system uses generalizable image capture and analysis techniques to verify that the user is properly wearing the measurement device, making the solution applicable to various measurement types including blood pressure, heart rate, and other vital signs

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A vital-data measurement controller is provided for controlling vital-data measurement when a user measures vital data by using a device data measurement. The measurement controller includes a controller that acquires image data including the user's face and the device by controlling a camera; and an image processor that authenticates the user's face and the based on the image data. The image processor then determines whether the device is worn by the user based on a positional relationship between the user and the device in the image data, and determines that a period in which the device is determined to be worn by the user after the authentication of the user and the device is a period of a proper state for measurement.
