Vehicle Air Guide Slat Assembly for Force-Stable Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air guiding devices for motor vehicle bodies face challenges in efficiently managing tensile and compressive forces without deforming the slat assembly, leading to increased manufacturing costs and complexity.
Innovation Solution
The slat assembly is designed to absorb both tensile and compressive forces through a combination of bearing points and coupling points, utilizing means such as landings and detent connections to transfer forces directly to the frame, eliminating the need for additional bearing elements and allowing for cost-effective assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If additional bearing elements are added to stabilize the slat assembly against deformation, then the stability and rigidity of the slat assembly is improved, but the device complexity and manufacturing costs increase
Solution Approach 1:
The patent merges the bearing function with the existing coupling points between slats and frame. The coupling points are designed to perform both the coupling function and the bearing function, eliminating the need for separate bearing elements. This integration resolves the contradiction by maintaining stability without increasing device complexity.
Solution Approach 2:
The coupling points are designed as multi-functional elements that simultaneously serve as connection points and bearing points. By making the coupling points universal (serving multiple functions), the patent avoids adding extra components while ensuring the slat assembly remains stable under aerodynamic forces.
2Strength
If additional bearing elements are added to prevent deformation of the slat assembly, then the rigidity of the slat assembly is improved, but the manufacturing costs increase
Solution Approach 1:
The bearing function is merged into the existing coupling points, eliminating the need for separate bearing elements. This reduces the number of components that need to be manufactured and assembled, thereby reducing manufacturing costs while maintaining the required rigidity of the slat assembly.
Solution Approach 2:
The patent extracts the bearing function from separate bearing elements and integrates it into the coupling points. By taking out the need for additional bearing elements, the manufacturing process is simplified and costs are reduced while the rigidity requirement is still met through the optimized coupling point design.
3Reliability
If the slat assembly is designed to absorb tensile and compressive forces, then the stability under aerodynamic forces is improved, but the structural complexity of individual slats increases
Solution Approach 1:
The force absorption capability is merged into the existing slat structure through optimized coupling points. The coupling points are designed to handle both tensile and compressive forces, eliminating the need for additional force-absorbing components. This maintains reliability while avoiding increased structural complexity.

AI summary
An air guiding device of a motor vehicle body of a motor vehicle includes a slat assembly. The slat assembly includes at least two slats, which are arranged so as to be borne rotatably about their axis of rotation in a frame of the air guiding device, and wherein, for rotation about the axis of rotation, the slat has a first bearing point and a second bearing point configured so as to lie opposite the first bearing point. For the rotatable bearing in the frame, the first bearing point of a first coupling point of the frame and the second bearing point of a second coupling point of the frame are arranged opposite one another. The slat is configured so as to absorb tensile and compressive forces.
