Solution Overview

Problem

Mobile robots equipped with displays do not consider real-time changes in user posture, leading to ergonomically inefficient viewing experiences when users adopt various postures.

Innovation Solution

A mobile robot with sensors, a display, and a driving unit, controlled by processors to identify user posture changes and adjust the display's position and angle to minimize physical fatigue.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the mobile robot provides a fixed display position and angle, then the device complexity is reduced, but the ergonomic efficiency deteriorates when users adopt various postures

Engineering Contradiction:
Improveergonomic efficiencyVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The display position and angle are made dynamic rather than fixed. The mobile robot continuously adjusts the display position and angle based on real-time detection of user posture changes, transforming a static system into a dynamic one that adapts to varying user conditions, thereby improving ergonomic efficiency without requiring overly complex manual adjustment mechanisms

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system implements feedback control by detecting user posture changes through sensors and using this information to automatically adjust the display position and angle. The processor receives posture data from sensors, determines the appropriate display configuration, and controls the display unit to maintain optimal viewing conditions, creating a closed-loop control system that resolves the contradiction between simplicity and ergonomics

Inventive Principle:
Principle #23Feedback

2Ease of operation

If the mobile robot does not adjust display based on user posture, then the device complexity is reduced, but the user satisfaction deteriorates

Engineering Contradiction:
Improveuser satisfactionVSAvoidcontrol complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The mobile robot performs self-adjustment of the display position and angle based on detected user posture changes. The system autonomously monitors user posture through sensors and automatically modifies display parameters without requiring manual user input or complex interaction, enabling the device to serve itself in optimizing viewing conditions

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Manual mechanical adjustment of the display is replaced with an automated sensor-based detection and control system. The processor uses sensing data to determine optimal display position and angle, substituting physical manual adjustment mechanisms with electronic sensing and control, thereby improving user satisfaction while keeping the overall system relatively simple

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

AI summary

A mobile robot is disclosed. The mobile robot comprises: at least one sensor; a display of which the angle can be adjusted; a driving unit; and one or more processors for identifying a posture change amount of a user for a threshold time on the basis of sensing data acquired through the at least one sensor, identifying that adjustment of the display is necessary when it is identified that the identified posture change amount is less than a threshold change amount, identifying a target position of the display and a target angle of the display when it is identified that adjustment of the position of the display is necessary, and controlling the driving unit on the basis of the target position of the display and the target angle of the display.
