Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle add-on part mounting systems face challenges such as complex multi-part designs, loss of clamping force over time, limited universality across different vehicle models, and material limitations due to high forces applied, leading to inefficient and adaptable solutions.
Innovation Solution
A one-piece mount with rotatable, rigid support elements and a direct clamping mechanism using a screw connection, where the support elements move towards each other to securely hold the body part, allowing for easy assembly and universal application without requiring special materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multi-part mounting devices are used, then the add-on part can be fastened to the body part, but the assembly process becomes complex and requires multiple steps
Solution Approach 1:
The patent combines multiple mounting components into a single integrated clamp structure. The clamp body (Klammkörper) incorporates both the clamping mechanism and the mounting function in one piece, eliminating the need for separate parts that need to be assembled. This single-component design maintains reliable fastening while significantly simplifying the assembly process.
Solution Approach 2:
The clamp is designed with a rotatable support element that can be inserted through the receiving opening in a specific orientation and then rotated to engage the body part. This segmentation of the insertion and engagement phases allows for simple assembly while ensuring reliable mounting.
2Reliability
If resilient or elastic elements are used in the clamping device, then the add-on part can be fastened, but the clamping force is lost over time
Solution Approach 1:
The patent removes resilient or elastic elements from the clamping device entirely. Instead of using elastic elements to provide clamping force, the invention employs a mechanical clamp with a screw connection that maintains constant clamping force without degradation over time. The clamp body and support element form a rigid mechanical structure that does not suffer from elastic fatigue.
3Reliability
If expandable clamps are used, then the add-on part can be fastened by expanding elastic elements, but the contact surface is limited to the opening surface
Solution Approach 1:
The patent introduces a rotatable support element that extends the contact surface from a single opening surface to multiple surfaces. When the support element is rotated into its engagement position, it provides additional contact surfaces on the outer circumference of the body part, significantly increasing the bracing area and improving fastening reliability.
4Reliability
If the holder is adapted to specific body parts, then secure fastening is achieved, but universality across different vehicle models is lost
Solution Approach 1:
The clamp is designed with a receiving opening that can accommodate body parts of different sizes and shapes. The rotatable support element can be positioned at different angular orientations to engage various body part geometries. This universal design allows the same clamp to securely fasten add-on parts to different body parts across various vehicle models without requiring model-specific adaptations.
5Strength
If special plastics are used for the clamping device, then the high forces can be withstood, but material selection is restricted
Solution Approach 1:
The patent changes the material parameter from specialized high-strength plastics to ordinary plastics or metal. The simplified clamp design without elastic elements reduces the mechanical stresses on the material, allowing the use of common, easily processable materials. This parameter change in material selection maintains sufficient strength while greatly improving manufacturability and reducing costs.
