Solution Overview
Problem
Current driverless transport systems in the motor vehicle industry face challenges in achieving precise and automated positioning of wheels for assembly, requiring manual intervention and lacking in secure and force-free positioning capabilities.
Innovation Solution
The design incorporates an add-on module with a base plate, linear guides, and a wheel receiving unit, allowing for precise positioning and self-centering of wheels, enabled by a system of interconnected linear guides and a counterweight, along with contactless power transmission and automated control, facilitating automatic wheel placement and secure mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual positioning of wheels is used, then flexibility is maintained, but positioning precision and automation are insufficient
Solution Approach 1:
The patent replaces manual mechanical positioning with an automated linear guide system. The linear guides (first, second, and third linear guides) enable automated, precise positioning of the wheel receiving unit along defined axes, eliminating the need for manual intervention while achieving millimeter-level positioning precision through mechanical guidance systems.
Solution Approach 2:
The wheel receiving unit is designed with self-centering capability through the concave receiving surface, which automatically centers the wheel without external intervention. The system performs its own positioning adjustment through the interaction of the linear guides and the wheel's geometry, reducing the need for external control mechanisms.
2Reliability
If secure fastening of wheels is implemented, then reliability is improved, but operational flexibility is reduced
Solution Approach 1:
The system transitions from a static, permanently fixed wheel mounting system to a dynamic, adjustable system. The linear guides enable the wheel receiving unit to move along the longitudinal and transverse axes, allowing the wheel to be positioned precisely and securely fastened at different locations while maintaining ease of adjustment through the guided motion system.
3Ease of operation
If force-free positioning is achieved, then ease of operation is improved, but system complexity increases
Solution Approach 1:
The patent introduces a counterweight system that balances the weight of the wheel and receiving unit, enabling force-free or minimal-force positioning. The counterweight offsets gravitational forces, allowing the wheel receiving unit to be moved easily along the linear guides without requiring significant operational effort to overcome gravity.

Function Achieved in This Case
Enables fully automatic, precise positioning of wheels with centimeter-level accuracy, reducing manual labor and ensuring secure attachment, while allowing for contactless power transmission and force-free operation, enhancing the automation and safety of intralogistical transport processes.
Implementation Method 1
the mobile part has a secondary winding on its underside for the contactless transmission of electrical power from an elongated primary conductor laid on the floor, i.e. on the travel plane, to the secondary winding
Implementation Method 2
the wheel receiving unit has a particularly concave receiving surface for a wheel. The advantage here is that self-centering is possible
