Solution Overview

Problem

Barrier-free kiosks with height adjustment functions frequently break down due to repeated height adjustments, and existing solutions do not efficiently optimize the kiosk height based on user physical conditions.

Innovation Solution

An intelligent barrier-free kiosk that uses cameras and a processor to recognize approaching users, learn their characteristic information, and adjust the kiosk height only when necessary to optimize user comfort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the kiosk height is repeatedly adjusted according to inputs of numerous users, then the adaptability to different user heights is improved, but the reliability of the stepping motor or sliding rail deteriorates due to frequent breakdowns

Engineering Contradiction:

Improveadaptability to different user heightsVSAvoidreliability of height adjustment mechanism

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system performs preliminary action by predicting user height and pre-adjusting the kiosk to an appropriate height before the user actually interacts with it. The camera captures images of approaching users, the processor predicts their height, and the height adjustment unit positions the kiosk accordingly in advance, so users find the kiosk already at a comfortable height without manual adjustment

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The kiosk serves itself by automatically detecting approaching users through the camera, predicting their height requirements, and adjusting its own height without user input. The system uses the user's own image data to automatically determine the optimal height setting, eliminating the need for users to manually operate the height adjustment mechanism

Inventive Principle:

Principle #25Self-service

2Ease of operation

If the kiosk height is adjusted frequently to accommodate different users, then the ease of operation for various users is improved, but the loss of time for height adjustment increases

Engineering Contradiction:

Improveease of operation for various usersVSAvoidtime for height adjustment

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The system performs height adjustment in advance before users need to interact with the kiosk. By capturing images of approaching users and predicting their height, the system pre-positions the kiosk at the optimal height, eliminating waiting time and making the interaction immediately convenient

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent replaces manual mechanical height adjustment with an automated system using camera-based user detection, AI-powered height prediction, and automatic height control. This substitution eliminates the need for users to manually operate mechanical adjustment mechanisms, saving time and improving ease of operation

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

Provided is a method of controlling an intelligent barrier-free kiosk including: recognizing a moving object, which is within a preset distance from the kiosk and is approaching the kiosk; learning characteristic information of the recognized moving object; determining, based on a result of the learning, whether a user related to the moving object intends to use the kiosk; and, based on determining that the user intends to use the kiosk, changing a height of the kiosk.
