Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional connecting components are used to attach the rear wing to the wing supporting device, then assembly is simplified, but positional accuracy and force absorption are insufficient
Solution Approach 1:
The connecting component is divided into two distinct parts: a trough-shaped receiving device and a hammer component. This segmentation allows each part to be optimized for its specific function - the trough provides precise positioning and force distribution, while the hammer component enables accurate insertion and secure attachment, thereby achieving high positional accuracy without excessive overall complexity.
Solution Approach 2:
The hammer component is designed to be received within the trough-shaped receiving device, creating a nested structure. The hammer head fits into the trough cavity, and the hammer handle extends outward for assembly operations. This nesting arrangement maximizes space utilization and ensures precise alignment while maintaining structural integrity for effective force absorption.
2Strength
If simple connecting components are used, then device complexity is reduced, but force and torque absorption capability is insufficient
Solution Approach 1:
The connecting components are designed with differentiated local qualities - the trough-shaped receiving device features a cavity optimized for receiving and distributing forces, while the hammer component has a specifically shaped head and handle for precise engagement. This local optimization ensures that each region of the connecting component performs its specific function efficiently, enabling superior force and torque absorption through strategically designed structural features.
3Manufacturing precision
If precise fit connecting components are used, then assembly precision is improved, but assembly difficulty increases due to force requirements
Solution Approach 1:
The trough-shaped receiving device and hammer component are pre-configured with complementary geometries that guide the assembly process. The trough cavity is shaped to receive the hammer head in a specific orientation, and the hammer handle is designed to facilitate insertion before final securing. This preliminary configuration ensures that components align correctly during assembly, achieving high precision without requiring excessive force or complex alignment procedures.

AI summary
An air guiding device for a motor vehicle includes a rear wing, a wing supporting device configured to secure the rear wing and to forward forces which act on the rear wing, and connecting components configured to connect the rear wing and the wing supporting device to one another. A first of the connecting components is configured as a trough-shaped receiving device on the rear wing and/or the wing supporting device. A second of the connecting components which interacts with the first connecting component is configured as a hammer component on the other of the rear wing and/or the wing supporting device. The hammer component has a hammer handle and a hammer head which is connected to the hammer handle, extends transversely with respect thereto, and is received in the trough-shaped receiving device.
