Nicotine Pod Connector Air Inlet Geometry for Blockage Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nicotine e-vaping devices face challenges in efficiently exposing the pod inlet to ambient air, leading to potential blockages and affecting the airflow during vaping.
Innovation Solution
The device body incorporates an angled upstream rim in the through hole to facilitate the exposure of the pod inlet, reducing air inlet blockage and enhancing airflow by directing ambient air into the pod inlet.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pod inlet is positioned within the through hole, then the device structure is compact and simple, but the pod inlet may be blocked from ambient air affecting airflow during vaping
Solution Approach 1:
The upstream rim is configured at an angle relative to the longitudinal axis of the through hole, creating a three-dimensional geometric feature that directs ambient air toward the pod inlet. This angular configuration transforms the airflow path from a potential blockage scenario into an active directing mechanism, exposing the pod inlet to ambient air while maintaining the compact integrated structure.
2Productivity
If the upstream rim is angled to expose the pod inlet, then airflow is enhanced and blockage is reduced, but the manufacturing precision requirements increase
Solution Approach 1:
The upstream rim is configured with a specific angular parameter relative to the longitudinal axis of the through hole. This parameter change transforms the rim from a simple circular edge into an active airflow directing feature. The angular configuration optimizes the exposure of the pod inlet to ambient air while maintaining manufacturability through standard molding or machining operations.

AI summary
A nicotine pod assembly for a nicotine e-vaping device may include a pod body and a connector module. The pod body has an upstream end and a downstream end and is configured to hold a nicotine pre-vapor formulation. The upstream end of the pod body defines a cavity. The connector module is configured to be seated within the cavity of the pod body. The connector module may include an external face and a side face. The external face of the connector module includes at least one electrical contact and defines a pod inlet. The side face of the connector module defines at least one module inlet. The side face of the connector module faces a sidewall of the cavity in the pod body when the connector module is seated within the cavity.
