Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing product registration systems are prone to inaccurate detection of scanning actions due to potential errors such as user movement or erroneous detection by sensors, leading to potential fraudulent operations.

Innovation Solution

A registration checking apparatus that utilizes video analysis to detect scanning actions by analyzing a user's hand, determines the relationship between the number of scanning actions and registered products, and performs output processing when the predetermined condition is not satisfied, ensuring accurate registration verification.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If a sensor composed of light emitter and light receiver is used to detect product passage, then product registration can be automated, but measurement precision deteriorates due to omitted detection and erroneous detection

Engineering Contradiction:

Improveautomation of product registrationVSAvoiddetection accuracy of scanning actions

Core Design Contradiction:

Extent of automationVSMeasurement precision

Solution Approach 1:

The patent replaces the optical sensor system (light emitter and light receiver) with a video-based detection system. The video acquisition unit captures images of the scanning area, and the scanning action detection unit analyzes these images to detect scanning actions. This substitution eliminates the measurement precision problems of the optical sensor while maintaining automation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a video signal as an intermediary between the physical scanning action and the detection system. Instead of directly detecting product passage with optical sensors, the system uses video images as an intermediate medium to capture and analyze scanning actions, thereby improving detection accuracy.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If optical sensors are used to detect scanning actions, then registration checking can be performed, but reliability deteriorates due to false detection of user movement as scanning actions

Engineering Contradiction:

Improveregistration checking capabilityVSAvoidaccuracy of scanning action detection

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent replaces the optical detection system with a video analysis system. The scanning action detection unit processes video images to distinguish between actual scanning actions and user movement, thereby improving reliability while maintaining productivity.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system uses video feedback to continuously monitor and analyze scanning actions. By processing video images in real-time, the system can provide feedback to distinguish valid scanning actions from false detections, improving the reliability of registration checking.

Inventive Principle:

Principle #23Feedback

AI summary

A registration checking apparatus (2000) determines, for a target transaction, whether a relation between the number of times scanning actions are performed and the number of products registered as checkout targets satisfies a predetermined condition. The scanning action is detected by analyzing a video (12). The registration checking apparatus (2000) performs predetermined output processing when the relation does not satisfy the predetermined condition. The predetermined condition is a condition being satisfied when the number of registered products is equal to or greater than the number of detected scanning actions.
