Solution Overview

Problem

Guide robots face challenges in accessing main electrical components for repair due to their covered positions, and the inconvenience of handling heavy display units, which complicates separation and rotation within the robot's structure.

Innovation Solution

A guide robot design featuring a case with a coupling hole and a door-type display structure that allows easy access to main electrical components, along with a movement guide device using slide guides and coupling devices to facilitate the rotation and separation of the display unit without requiring separate transportation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the display unit is coupled to the main body to provide service information, then the user can access information conveniently, but access to main electrical components for repair becomes difficult

Engineering Contradiction:
ImproveUser access to display informationVSAvoidAccess to main electrical components
Core Design Contradiction:
Ease of operationVSEase of repair

Solution Approach 1:

The display unit is segmented from the main body through a coupling mechanism that allows independent access. The coupling hole and coupling devices enable the display unit to be separated into distinct segments, allowing repair personnel to access main electrical components without moving the entire display unit, thus resolving the contradiction between user convenience and repair accessibility

Inventive Principle:
Principle #1Segmentation

2Ease of repair

If the screen unit is completely separated from the main body for repair, then access to internal components is easy, but the heavy weight of the screen unit makes separate transportation inconvenient

Engineering Contradiction:
ImproveAccess to internal componentsVSAvoidScreen unit weight
Core Design Contradiction:
Ease of repairVSWeight of moving object

Solution Approach 1:

The coupling mechanism divides the system into separable segments (display unit and main body) that can be partially disconnected. This allows repair personnel to access internal components through the coupling hole without completely separating the heavy display unit from the main body, eliminating the need to transport the entire heavy unit while still providing adequate access for repairs

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The coupling hole extracts or opens a specific access point in the main body structure, allowing repair personnel to reach internal components through this extracted opening without removing the entire display unit. This selective extraction provides repair access while avoiding the need to move the heavy display unit

Inventive Principle:
Principle #2Taking out (Extraction)

3Shape

If the display unit is inclinedly coupled along an inclined case to fit the structure, then the display unit can be installed at the desired angle, but rotation of the display unit is interfered with

Engineering Contradiction:
ImproveDisplay unit inclinationVSAvoidRotation of display unit
Core Design Contradiction:
ShapeVSEase of operation

Solution Approach 1:

The coupling devices incorporate rotational freedom that allows the display unit to dynamically adjust its orientation. The coupling mechanism maintains the inclined positioning while enabling rotation around the coupling axis, allowing the display unit to be inclined for structural fit while still permitting rotation for operational flexibility

Inventive Principle:
Principle #15Dynamics

AI summary

The guide robot includes a case having a coupling hole and a door type display structure that is capable of opening or closing the coupling hole. Access to the body part in which main electrical components are provided may be easy. An installation plate coupled to a main frame, a slide guide and a guide plate, which are coupled to the installation plate, and a plurality of link type coupling devices coupled to one side of the guide plate and connected to the display unit may be provided to open or close the coupling hole by rotating the display unit after the display unit slidably moves.
