Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nicotine e-vaping devices face challenges in efficiently heating nicotine pre-vapor formulations and ensuring proper air flow, leading to inconsistent vapor production and user experience.
Innovation Solution
A nicotine pod assembly with a first section configured to hold a nicotine pre-vapor formulation and a second section designed to heat the formulation, featuring a flow path with diverged and converged portions to optimize air flow, and a device body with a through hole that securely receives the pod assembly, exposing the pod inlet for air flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the nicotine pod assembly uses a simple flow path design, then the device complexity is reduced, but the air flow management becomes insufficient leading to inconsistent vapor production
Solution Approach 1:
The flow path is segmented into distinct functional zones: a first diverged portion that splits air flow into multiple streams, a second diverged portion that further divides the flow, and a converged portion that merges the streams. This segmentation allows complex air flow management to be achieved through modular structural divisions rather than a single complicated passage.
Solution Approach 2:
The flow path design utilizes three-dimensional spatial arrangement by creating diverged portions that extend in different directions and a converged portion that brings them together. This dimensional approach to flow path design enables sophisticated air mixing and distribution without requiring excessively long or convoluted passages, maintaining compactness while achieving reliable vapor production.
2Reliability
If the device body securely retains the pod assembly, then the connection reliability is improved, but the ease of operation for pod replacement is reduced
Solution Approach 1:
The downstream protrusion is designed to be retractable relative to the downstream sidewall, creating a dynamic retention mechanism. During normal operation, the protrusion engages with the pod assembly to secure it firmly. When pod replacement is needed, the protrusion can retract to release the pod, enabling easy removal. This dynamic feature allows the same structure to provide both strong retention and easy release.
Solution Approach 2:
The retention mechanism appears to utilize spring-loaded or elastic protrusions that automatically engage with the pod assembly upon insertion and provide continuous retention force. The design suggests that the mechanical properties of the protrusion material or structure enable automatic engagement and release without requiring additional actuators or complex control systems.
3Use of energy by moving object
If the heater is in direct thermal contact with the wick, then the heating efficiency is improved, but the risk of overheating and dry burning increases
Solution Approach 1:
The thermal contact between the heater and wick is optimized by ensuring the heater is positioned to heat the wick at the location where nicotine pre-vapor formulation is present. This localized heating approach maximizes heating efficiency where needed while avoiding heating of dry wick material that could lead to overheating or combustion.
Solution Approach 2:
The wick is configured to move the nicotine pre-vapor formulation to the heater before heating occurs, ensuring that the wick material is saturated with nicotine formulation prior to the heating action. This preliminary saturation of the wick prevents dry burning and overheating while maintaining efficient heat transfer to the nicotine formulation.

AI summary
A nicotine pod assembly for a nicotine e-vaping device may include a first section and a second section connected to the first section. The first section may define a pod outlet and be configured to hold a nicotine pre-vapor formulation. The second section may define a pod inlet and be configured to heat the nicotine pre-vapor formulation. The pod inlet is in fluidic communication with the pod outlet via a flow path. The flow path may include a first diverged portion, a second diverged portion, and a converged portion. A nicotine e-vaping device may include a device body defining a through hole configured to receive the nicotine pod assembly such that a pod inlet for the air flow is exposed when the nicotine pod assembly is seated within the through hole.
