Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current conveying systems for transporting components in production environments, such as those for vehicle production, face challenges in achieving precise and repeatable alignment of containers and roller trolleys with driverless transport vehicles, leading to potential collisions and inefficiencies in transferring components to rotary frames, especially due to manufacturing tolerances and measurement inaccuracies.
Innovation Solution
The implementation of a conveying system with a driverless transport vehicle and positioning devices, including apparatus-side and vehicle-side positioning devices, allows for direct interaction to align the apparatus relative to the vehicle, ensuring precise and repeatable positioning of containers and roller trolleys, enabling automatic and collision-free transfer to rotary frames.

Engineering Contradiction Analysis
1Extent of automation
If driverless transport vehicles are used to transport components, then automation and efficiency are improved, but positioning precision and alignment accuracy deteriorate due to manufacturing tolerances and measurement inaccuracies
Solution Approach 1:
A positioning device acts as an intermediary between the driverless transport vehicle and the apparatus (roller trolley/container). The positioning device includes a positioning element with a positioning surface that directly contacts the apparatus, while the vehicle has a corresponding positioning receptacle. This mechanical intermediary compensates for positioning errors by providing a dedicated alignment interface that ensures precise registration despite variations in vehicle positioning or apparatus dimensions.
Solution Approach 2:
The positioning device allows for adjustment of positioning parameters such as the position of the positioning surface relative to the vehicle chassis. This enables compensation for manufacturing tolerances and measurement inaccuracies by modifying the geometric parameters of the positioning interface to achieve optimal alignment between the vehicle and the apparatus.
2Measurement precision
If direct interaction between positioning devices is implemented, then alignment accuracy is improved, but device complexity increases due to additional positioning mechanisms
Solution Approach 1:
The positioning device serves as a specialized intermediary component that provides direct mechanical interaction between the vehicle and apparatus. Rather than relying on complex sensor systems or multiple adjustment mechanisms, the invention uses a dedicated positioning element with a positioning surface that directly contacts the apparatus, creating a simple yet effective alignment interface that reduces overall system complexity while maintaining high alignment accuracy.
3Reliability
If precise positioning is achieved through direct interaction of positioning devices, then collision risk is reduced, but system complexity increases due to additional positioning components
Solution Approach 1:
The positioning device acts as a mechanical intermediary that ensures collision-free operation by providing a dedicated alignment interface. The positioning element with its positioning surface directly contacts the apparatus, creating a physical guide that prevents misalignment and potential collisions during the transfer operation, while keeping the system relatively simple through this focused alignment mechanism.
