Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing assemblies for heat recovery and exhaust gas recirculation systems in motor vehicles require complex mounting processes due to separate supports and numerous screw connections, occupying additional installation space and increasing manufacturing costs.
Innovation Solution
A compact assembly design where the actuator is directly connected to a vehicle structure via a planar connecting surface, often using an intermaterial bond like gluing or soldering, eliminating the need for additional supports and screw connections, allowing for a simplified and cost-effective manufacturing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the actuator is screwed onto a separate support, then the mounting is relatively complex and the support occupies installation space, but the actuator can be securely fastened to the vehicle structure
Solution Approach 1:
The patent combines the actuator housing with the mounting function by integrating a planar connecting surface directly into the actuator housing. This eliminates the separate support component and reduces the number of screw connections needed, thereby simplifying the mounting process and reducing device complexity while maintaining secure fastening to the vehicle structure
2Ease of manufacture
If the actuator is screwed onto a separate support, then the actuator can be securely fastened, but additional installation space is required for the support
Solution Approach 1:
The actuator housing is designed with an integrated planar connecting surface that serves both as the actuator housing and the mounting interface. This merging of functions eliminates the need for a separate support structure, thereby reducing the installation space required while ensuring secure fastening through multiple screw connections on the planar surface
3Reliability
If multiple screw connections are used to fasten the actuator to the vehicle structure, then the fastening is secure, but the mounting process becomes complex and costly
Solution Approach 1:
The planar connecting surface is integrated into the actuator housing, providing a stable mounting interface that accommodates multiple screw connections. This integration ensures secure fastening to the vehicle structure while simplifying the mounting process by eliminating the need for separate support structures and reducing the overall number of fastening operations required
