Nicotine Pod Retention Structure for Leak-Resistant Seating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nicotine e-vaping devices face challenges in securely and efficiently retaining nicotine pod assemblies, which can lead to improper seating and potential leakage or blockages, affecting the vaping experience and device performance.
Innovation Solution
The nicotine e-vaping device incorporates a device body with upstream and downstream protrusions and recesses that engage with corresponding features on the nicotine pod assembly, facilitating secure pivoting and seating within a through hole, ensuring proper alignment and electrical connection, while also providing haptic and auditory feedback for user confirmation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple insertion method is used for nicotine pod assembly, then ease of operation is improved, but retention security deteriorates leading to improper seating and potential leakage
Solution Approach 1:
The device employs asymmetric protrusions and corresponding recesses on the pod assembly that create a unidirectional insertion path. The protrusions guide the pod into the correct orientation while preventing improper seating, thus maintaining ease of operation while improving retention security through geometric constraint rather than complex mechanisms.
Solution Approach 2:
The pod assembly is designed to nest within the device body through a through-hole, with protrusions and recesses creating an interlocking fit. This nested structure ensures the pod is securely retained while allowing for simple insertion and removal operations.
2Reliability
If protrusions and recesses are added to ensure secure retention, then reliability is improved, but device complexity increases
Solution Approach 1:
The engagement features use simple asymmetric geometric shapes (protrusions and recesses) rather than complex mechanical structures. This approach achieves reliable pod retention through clever geometric design rather than adding multiple components or complex mechanisms, thus improving reliability while minimizing increases in device complexity.
3Ease of operation
If manual or puff activation is used, then ease of operation is improved, but precision of activation control deteriorates
Solution Approach 1:
The device incorporates sensors that detect user activation (manual button press or puff) and provide feedback control to the heating element. This feedback mechanism allows for precise control of vaporization parameters while maintaining simple user interaction through manual or puff-based activation methods.

AI summary
A nicotine e-vaping device may include a nicotine pod assembly and a device body. The nicotine pod assembly has upstream and downstream ends and is configured to hold a nicotine pre-vapor formulation. The upstream end may define at least one upstream recess, and the downstream end may define at least one downstream recess. The device body defines a through hole configured to receive the nicotine pod assembly. The through hole includes an upstream sidewall and a downstream sidewall. The upstream sidewall may include at least one upstream protrusion, and the downstream sidewall may include at least one downstream protrusion. The at least one upstream protrusion and the at least one downstream protrusion may be configured to engage with the at least one upstream recess and the at least one downstream recess, respectively, so as to retain the nicotine pod assembly within the through hole of the device body.
