Solution Overview

Problem

The manual handling of material tracks during material discharge and loading in processing machines for rail goods is inefficient and difficult to automate, particularly due to the need for precise coordination and alignment of the free end section.

Innovation Solution

The integration of a robot controlled by a control unit with gripping tools and an overturning device at the material feeding station, allowing for automated material absorption and positioning, reduces the need for manual intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual handling is used for material loading and unloading, then flexibility and adaptability to individual situations are maintained, but productivity is reduced and time is lost

Engineering Contradiction:
Improvematerial loading and unloading efficiencyVSAvoidautomation of material handling
Core Design Contradiction:
ProductivityVSExtent of automation

Solution Approach 1:

The system enables automatic material loading and unloading through the robot's autonomous gripping, positioning, and coordination with the conveyor system, eliminating the need for manual intervention and significantly improving productivity

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical handling with an automated robot system equipped with gripping tools and controlled by a control unit, substituting human operation with automated mechanical and control systems

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

2Manufacturing precision

If manual intervention is used for material positioning, then precise coordination and alignment can be achieved, but loss of time increases due to manual operations

Engineering Contradiction:
Improvepositioning precision of free end sectionVSAvoidtime for material loading and unloading
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The robot system autonomously performs the positioning task with high precision through automated control, eliminating manual positioning time while maintaining or improving positioning accuracy through sensor feedback and controlled movement

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The control unit coordinates the robot's positioning actions with the conveyor system, using feedback control to achieve precise alignment of the free end section with the material feed station, reducing positioning time while ensuring accuracy

Inventive Principle:
Principle #23Feedback

3Productivity

If automated conveyor system is used, then continuous material conveyance is achieved, but material loading and unloading cannot be performed solely by the conveyor system

Engineering Contradiction:
Improvecontinuous material conveyanceVSAvoidsystem complexity for material handling
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent merges the automated conveyor system with a robot system equipped with gripping tools and a control unit, creating an integrated material handling system that combines the continuous conveyance capability of the conveyor with the flexible loading/unloading capability of the robot

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The robot system with gripping tools serves multiple functions: it can load material onto the conveyor, unload material from the conveyor, position the free end section, and adapt to different material configurations, making the system versatile while maintaining continuous operation

Inventive Principle:
Principle #6Universality (Multi-functionality)
