Solution Overview

Problem

Conventional methods for filling assemblies on automotive production lines require significant manual effort and are inefficient when handling multiple different filling adapters at various positions, making it difficult to manage and maintain the process.

Innovation Solution

An industrial robot with a compensating gripper is used to remove and place filling adapters in an adapter tray, with synchronized drives and a compensating mechanism to handle positional deviations, allowing for easy integration of new adapters and reduced manual labor.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If manual handling of filling adapters is used, then simplicity of system is maintained, but productivity and operational efficiency deteriorate due to significant manual effort required

Engineering Contradiction:
Improveautomation of adapter handlingVSAvoidcomplexity of handling system
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The robot system automatically removes and places filling adapters without human intervention. The robot autonomously navigates to the vehicle, removes the adapter from the filling position, and places it in the adapter tray, making the system self-sufficient for adapter handling tasks

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The robot system is designed to handle multiple different types of filling adapters at various positions on different vehicle types. The same robot can adapt to handle fuel adapters, lubricant adapters, coolant adapters, and other operating material adapters, providing universal functionality

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

2Adaptability or versatility

If conventional handling systems are used, then system structure is simple, but adaptability deteriorates when handling multiple different filling adapters at different positions

Engineering Contradiction:
Improveadaptability to different adapters and positionsVSAvoidcomplexity of synchronized control system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The traversing console and robot axis are equipped with independently controllable synchronized drives that can dynamically adjust their positions and movements. This dynamic control system allows the robot to reach various positions on the vehicle while maintaining synchronization with the traversing console, enabling adaptation to different adapter positions

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The synchronized drive system incorporates feedback control to coordinate the movement of the traversing console and robot axis. The system monitors and adjusts the positions of both components to ensure they move in coordination, enabling the robot to accurately reach filling positions on moving vehicles

Inventive Principle:
Principle #23Feedback

3Manufacturing precision

If rigid connection between traversing console and robot axis is used, then control is simplified, but manufacturing precision deteriorates due to vehicle tolerances and position deviations

Engineering Contradiction:
Improveprecision of adapter removal positionVSAvoidcomplexity of independent drive systems
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The system uses dynamically controllable independent drives on both the traversing console and robot axis, allowing real-time adjustment of positions to compensate for vehicle tolerances and ensure precise adapter removal despite manufacturing variations

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The independent drive systems incorporate feedback control to monitor and adjust positions, enabling the robot to accurately locate and remove adapters even when vehicle components have manufacturing tolerances that cause position variations

Inventive Principle:
Principle #23Feedback

4Ease of operation

If industrial robot with compensating gripper is used, then ease of operation improves by minimizing manual effort, but device complexity increases due to compensating mechanism

Engineering Contradiction:
Improveease of adapter handlingVSAvoidcomplexity of compensating gripper system
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The compensating gripper autonomously compensates for position deviations and angular offsets during adapter removal without requiring manual adjustment. The gripper's built-in compensation mechanism automatically adapts to variations in adapter positioning, making the operation easier and more consistent

Inventive Principle:
Principle #25Self-service
