Solution Overview

Problem

Existing food-processing devices face issues with user authentication, as users often share or lend terminals, ID cards, or passwords, leading to unauthorized access and authentication by the wrong individuals, and there is a risk of device misuse when users move away from the device after authentication.

Innovation Solution

A food-processing device equipped with a processor, imaging device, and authentication part that captures and authenticates users based on iris images, ensuring precise user identification and automatically terminating authentication if the user moves away from the device's proximity, using biometric information to prevent unauthorized access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional authentication methods (terminals, ID cards, passwords) are used, then ease of operation is improved, but reliability deteriorates due to sharing and lending of authentication credentials

Engineering Contradiction:
Improveease of authenticationVSAvoidauthentication accuracy
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent replaces mechanical authentication methods (physical terminals, ID cards, passwords) with biometric authentication using iris recognition. The imaging device captures iris patterns and the authentication part verifies user identity based on these unique biological characteristics, eliminating the need for physical authentication objects that can be shared or lost.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If authentication is maintained after user moves away, then productivity is improved, but reliability deteriorates due to potential misuse by unauthorized users

Engineering Contradiction:
Improvecontinuous operationVSAvoidauthorized access
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The determination part continuously monitors whether the authenticated user remains in proximity to the food-processing device. When the user moves away beyond a predetermined distance, the system receives feedback about the user's absence and automatically terminates the authentication status, preventing unauthorized use while allowing continuous operation when the user is present.

Inventive Principle:
Principle #23Feedback

3Reliability

If biometric authentication is implemented, then reliability is improved, but device complexity increases due to additional imaging and authentication components

Engineering Contradiction:
Improveauthentication accuracyVSAvoidsystem structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The imaging device serves multiple functions: it captures images for biometric authentication, monitors user presence through continuous imaging, and provides visual feedback during the authentication process. This multi-functionality reduces the need for separate dedicated components for each function, thereby limiting the increase in device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

An object of the present invention is to provide a food-processing device with which situations in which a user is authenticated who should not be and situations in which an authenticated user is not the same person as an actual user are avoided, and only an authenticated user can execute a process. A food-processing device (10) is a device that comprises a processor (61), an imaging device (60), an authentication part (63), and a management part (64), and that processes a food (A) in a line in which the food is manufactured. The processor performs at least one process on the food. The imaging device captures an image of an eye of a user of the food-processing device. The authentication part authenticates the user on the basis of the image of the user's eye captured by the imaging device. The management part makes the process performed by the processor executable for the user authenticated by the authentication part. The authentication part authenticates the user on the basis of information of the user's iris included in the image of the user's eye.
