Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional assembly bearings for motor vehicle assemblies face challenges in providing sufficient installation space and cost-effectiveness for damping and impact characteristics, with external stops being difficult to fasten and adding extra components and costs.
Innovation Solution
An assembly bearing design featuring an outer part composed of two half-shells clipped to a fastening element, which generates an undercut and overlap to serve as a stop, eliminating the need for additional installation space and components, and allowing for simple and cost-effective fastening and transport securing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If stops are placed on from the outside in conventional assembly bearings, then the movement of the inner part can be delimited, but the fastening becomes difficult and process-intensive, and additional components and costs are required
Solution Approach 1:
The patent combines the stop function with the outer part structure itself. The outer part is designed with an integrated stop element that forms part of the original component, eliminating the need for separate stop components and simplifying the fastening process to a single clipping operation.
Solution Approach 2:
The outer part serves multiple functions simultaneously: it provides structural support, enables clipping fastening to the supporting body, and incorporates the stop function to delimit inner part movement. This multi-functionality reduces the total number of components required.
2Reliability
If additional components are used for stops in conventional assembly bearings, then movement delimitation is achieved, but additional costs and component complexity are introduced
Solution Approach 1:
The stop function is merged into the outer part structure, creating a monolithic component that performs both structural and movement delimitation functions. This integration eliminates additional stop components and reduces overall assembly complexity.
Solution Approach 2:
The outer part is designed as a multi-functional component that simultaneously provides mechanical support, clipping fastening capability, and movement delimitation through its integrated stop feature, thereby reducing the total component count.
3Reliability
If external stops are added to conventional assembly bearings, then movement delimitation is provided, but installation space requirements increase
Solution Approach 1:
The stop feature is integrated into the existing outer part geometry, utilizing the same installation space already allocated for the outer part. No additional radial or axial space is required beyond what is already needed for the outer part structure.
Solution Approach 2:
The outer part serves as both the structural housing and the movement delimitation element through its integrated stop, eliminating the need for separate space-consuming stop components.
