Innovation Solution
An atomizing device with a permeating component having a porous structure and a large heat-absorbing surface, where the tobacco liquid permeates via capillary action and is heated by a heating element to generate a larger amount of aerosol, with the heating element being in contact with the heat-absorbing surface and electrically connected to a power supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a heating wire is wound around a liquid conducting component, then the device structure is simple, but the contact surface between the heating wire and the liquid conducting component is small, limiting aerosol generation
Solution Approach 1:
The patent applies porous materials by using a permeating component with porous structure that allows liquid to permeate through capillary action. The heating element is arranged on the permeating component such that it contacts the liquid at multiple points through the porous structure, significantly increasing the effective contact surface area compared to a simple wound wire configuration.
Solution Approach 2:
The patent transitions from a one-dimensional wound wire contact to a two-dimensional surface contact by arranging the heating element on the permeating component. This dimensional change allows the heating element to contact the liquid across a larger surface area, thereby increasing aerosol generation capacity.
2Productivity
If a heating wire is wound around a liquid conducting component, then the device structure is simple, but the aerosol generation performance is unsatisfactory
Solution Approach 1:
The permeating component with porous structure enables improved aerosol generation by allowing uniform liquid distribution across the heating surface. This structural feature enhances productivity while maintaining reasonable device complexity through the use of a single integrated permeating component.
Solution Approach 2:
The permeating component acts as an intermediary between the liquid supply and the heating element. It facilitates efficient liquid-to-heat transfer through its porous structure, thereby enhancing aerosol generation capacity without requiring direct contact between the liquid reservoir and heating element, thus managing device complexity effectively.
3Quantity of substance
If a small contact surface is used between heating wire and liquid conducting component, then the device is compact, but the aerosol generation amount is limited
Solution Approach 1:
The porous permeating component enables increased aerosol generation within a compact volume by maximizing the surface area-to-volume ratio. The porous structure provides extensive liquid-contact surface area within a small physical footprint, allowing high aerosol output without increasing overall device volume.
Solution Approach 2:
The heating element is arranged within and on the permeating component structure, creating a nested configuration where the heating element is integrated into the porous matrix. This nesting allows maximum contact surface area within minimal device volume, resolving the contradiction between aerosol amount and device size.
