Solution Overview
Problem
Conventional electronic cigarette atomizers are small, limiting the amount of vapor generated per puff and allowing only a single flavor to be stored, which affects user experience.
Innovation Solution
An electronic cigarette atomizer with a flared vapor outlet pipe, featuring a large cross-section mouthpiece cavity and a vapor outlet pipe with increasing inner diameter, allowing for increased vapor flow and accommodating multiple flavors by integrating a liquid storage chamber and atomization device with a ribbed plate and permeation system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the atomizer size is increased to generate more vapor per puff, then the vapor quantity increases, but the device size and complexity increase
Solution Approach 1:
The atomizer is divided into distinct functional segments: a mouthpiece segment with a large cross-section cavity for vapor accumulation and delivery, a liquid storage segment for e-liquid reservoir, and an atomization segment with the heating element. This segmentation allows each part to be optimized independently, enabling large vapor output without proportionally increasing the entire device volume.
Solution Approach 2:
The vapor outlet pipe features a flared design where the inner diameter gradually increases from the atomization chamber end to the mouthpiece end. This dimensional change in the outlet geometry expands the vapor flow cross-section without significantly increasing the atomization chamber volume, allowing more vapor to pass through per puff while maintaining compact overall size.
2Adaptability or versatility
If multiple flavors are stored in the atomizer, then flavor variety increases, but the device structure becomes more complex
Solution Approach 1:
The atomizer is designed as a modular system with separable components including the atomization device, connecting member, and liquid storage chamber. This segmentation allows users to easily replace cartridges or liquid reservoirs to switch between different e-liquid flavors, providing flavor variety without requiring complex internal mechanisms within each component.
Solution Approach 2:
The atomization chamber and heating assembly are designed as universal components that can work with different e-liquid formulations and flavors. The standardized connecting interface and liquid delivery system allow the same atomization mechanism to handle various liquid compositions, enabling multi-flavor capability without increasing the complexity of the core atomization system.
3Productivity
If the vapor outlet pipe inner diameter is increased to improve vapor flow, then vapor delivery improves, but heat dissipation becomes more difficult
Solution Approach 1:
The vapor outlet pipe employs a flared geometry where the cross-sectional area gradually increases along the flow direction. This dimensional transition allows vapor to expand and accelerate through the larger outlet opening, improving vapor delivery. Simultaneously, the increased surface area of the flared structure enhances radiative and convective heat dissipation from the vapor stream, counteracting heat accumulation despite the larger flow path.
