Solution Overview

Problem

Conventional robot traveling systems lack sufficient space for maintenance and access to machines installed along the rail, making it difficult for users to physically access these machines for maintenance and other work.

Innovation Solution

A robot traveling system with a rail, movable carriage, and a cable track that is laid along the lower side of the rail, incorporating a servo motor-powered drive mechanism and a timing belt system to move the carriage and robot, ensuring the cable track's width does not exceed the rail and carriage dimensions, allowing for reduced space occupation and easy access to machines.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the cable track is laid at the bottom side of the carriage, then the cable is protected and organized, but the space for accessing machines installed along the rail is reduced

Engineering Contradiction:
Improvecable protectionVSAvoidmachine accessibility
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The cable track is moved from a horizontal arrangement to a vertical arrangement along the lower side of the rail. This dimensional change allows the cable track to occupy vertical space rather than horizontal space, thereby protecting cables while maintaining horizontal accessibility for machine maintenance.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Area of stationary object

If the cable track width is reduced to match the rail width, then space occupation is minimized, but cable housing capacity is reduced

Engineering Contradiction:
Improvespace occupationVSAvoidcable housing
Core Design Contradiction:
Area of stationary objectVSReliability

Solution Approach 1:

The cable track utilizes the vertical dimension by running along the lower side of the rail, allowing it to provide adequate cable housing capacity without increasing the horizontal width beyond the rail width, thus minimizing space occupation while maintaining cable protection.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

If machines are installed along the rail, then the system functionality is enhanced, but the space for maintenance access is further reduced

Engineering Contradiction:
Improvesystem functionalityVSAvoidmaintenance access
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

By positioning the cable track vertically along the lower side of the rail, the invention frees up horizontal space that would otherwise be occupied by the cable track, thereby maintaining adequate access space for machine maintenance even when machines are installed along the rail.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
