Solution Overview

Problem

Vehicle assembly lines face challenges in efficiently switching between different vehicle models due to the need for various roof shapes and corresponding assembly tools, leading to space and time inefficiencies in assembly stations.

Innovation Solution

A device and method for handling a vehicle assembly tool carrier with two supporting surfaces, where the first and second handling devices jointly lift, rotate, and lower the carrier to reconfigure the clamping frames for different vehicle types, allowing for efficient conversion between assembly variants with minimal space and time requirements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple clamping frames for different vehicle models are kept in stock at assembly stations, then adaptability to different vehicle types is improved, but space requirements and device complexity increase

Engineering Contradiction:
Improveadaptability to different vehicle modelsVSAvoidspace requirement for assembly station
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The tool carrier is designed with multiple bearing surfaces that can each support different clamping frames. By rotating the carrier to different angular positions, the same physical device can present different tool configurations to the assembly station, making one device perform multiple functions that would otherwise require multiple separate devices

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

Solution Approach 2:

The tool carrier is made rotatable about a vertical axis, transforming a static arrangement of tools into a dynamic system. This rotation capability allows the assembly station to access different clamping frames by changing the angular position of the carrier, enabling quick model changes without physical reconfiguration or additional storage space

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If multiple clamping frames are kept in stock for different vehicle models, then adaptability is improved, but assembly changeover time increases

Engineering Contradiction:
Improveadaptability to different vehicle modelsVSAvoidassembly changeover time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

Multiple clamping frames are pre-positioned on different bearing surfaces of the tool carrier before the changeover is needed. When a model change is required, the carrier is simply rotated to bring the appropriate pre-positioned frame into the working position, eliminating the need for time-consuming assembly or reconfiguration during the changeover process

Inventive Principle:
Principle #10Preliminary action

3Area of stationary object

If a single tool carrier is used with multiple bearing surfaces, then space efficiency is improved, but device complexity increases

Engineering Contradiction:
Improvespace requirement for tool storageVSAvoidcomplexity of tool carrier system
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The tool carrier is segmented into multiple bearing surfaces (at least two) that can independently support different clamping frames. This segmentation allows each surface to be optimized for specific tool types while the overall system maintains a compact, space-efficient design through the shared carrier structure

Inventive Principle:
Principle #1Segmentation
