Asymmetrical Overmold Interface for Fluid Carrying Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid carrying systems face challenges in creating efficient and durable interfaces between fluid transport components and overmold components, particularly in ensuring a secure fluid connection and sealing mechanism that maintains fluid communication while allowing for asymmetrical designs.
Innovation Solution
A fluid carrying system comprising a fluid transport component and an overmold component, where the overmold component overlaps and extends beyond the fluid transport component, featuring a fluid conduit with a longitudinal axis angled relative to the interface, and a sealing surface that interacts with another component to restrict fluid flow, ensuring fluid communication and secure sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional interface design is used between fluid transport component and overmold component, then the manufacturing process is simple, but the fluid connection security and sealing performance are insufficient
Solution Approach 1:
The overmold component is designed with an asymmetrical body that does not exhibit symmetry about any plane passing through its longitudinal axis. This asymmetrical design creates a unique interface geometry that enhances fluid connection security while maintaining manufacturability through standard overmolding processes.
Solution Approach 2:
The interface design incorporates a sealing surface that extends perpendicular to the longitudinal axis, creating a multi-dimensional sealing interface. This dimensional approach provides robust sealing performance by distributing sealing forces across multiple surfaces rather than relying on a single linear interface.
2Reliability
If the fluid conduit longitudinal axis is perpendicular to the interface, then the manufacturing alignment is easier, but the sealing performance and fluid flow efficiency are reduced
Solution Approach 1:
The longitudinal axis of the fluid conduit is deliberately angled at a non-perpendicular orientation relative to the interface plane. This parameter change optimizes fluid flow dynamics and sealing contact pressure distribution, while the asymmetrical overmold body compensates for the alignment complexity through its geometric design.
3Adaptability or versatility
If the overmold component is symmetrical, then the manufacturing process is simpler, but the design versatility and functional adaptability are limited
Solution Approach 1:
The overmold component body is designed to be asymmetrical, lacking symmetry about any plane containing its longitudinal axis. This asymmetry enables versatile functional configurations and adaptive designs for different fluid carrying applications, while the overall molding process remains feasible through standard overmolding techniques.
