Intake Line Clip Mounting for Fuel Tank Venting Components
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for assembling functional components on the suction line of a combustion engine are complex, costly, and prone to unintentional loosening, particularly when using valves and venturid jets for fuel ventilation.
Innovation Solution
A clip connection system is used to securely attach functional components, such as valves or venturid jets, directly to the intake line without additional connection elements, allowing for simple, tool-free assembly and ensuring a secure, non-solvable connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If welding is used to attach functional components to the intake line, then the connection is secure and reliable, but the assembly process becomes complex and costly
Solution Approach 1:
The patent replaces the welding process (thermal/mechanical system) with a clip connection system (mechanical fastening system). The clip (44) engages with the clip receptacle (54) to provide a secure mechanical connection that eliminates the need for welding, thereby simplifying assembly while maintaining connection reliability.
2Reliability
If additional connection elements are used to attach the functional component, then the connection is secure, but the assembly process becomes more complex and time-consuming
Solution Approach 1:
The patent merges the functional component (10) directly with the clip connection means (42) integrated into its structure. The clip (44) and clip receptacle (54) are formed as integral parts of the functional component and intake line respectively, eliminating the need for separate connection elements and enabling tool-free, rapid assembly.
Solution Approach 2:
The clip connection system is designed to be self-installing without requiring additional tools or auxiliary connection elements. The clip (44) automatically engages with the clip receptacle (54) when the functional component is positioned on the intake line, enabling quick assembly and disassembly operations.
3Ease of manufacture
If a simple clip connection is used without additional securing features, then the assembly is simple and cost-effective, but the connection is prone to unintentional loosening
Solution Approach 1:
The patent incorporates a locking mechanism that prevents unintentional loosening before it can occur. The clip (44) features a locking tab (44b) that engages with a corresponding feature in the clip receptacle (54) to prevent the clip from disengaging, thereby providing preliminary protection against loosening while maintaining manufacturing simplicity.
4Reliability
If expensive materials are used for the intake line to ensure quality, then the overall quality is high, but the cost increases significantly
Solution Approach 1:
The patent applies different material qualities to different components based on their specific requirements. The functional component (10) is manufactured from high-quality plastic suitable for its specific function, while the intake line (12) can be made from cheaper plastic since it serves as a structural carrier. The clip connection system enables this differentiation without compromising overall assembly quality.
