Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional vaporizers face issues with inconsistent warming of intake air, difficulty in delivering high-viscosity vaporization media, and limited vaporization area, particularly with heating coils that only atomize in a restricted area.
Innovation Solution
The design includes an air warming space within the heating element to uniformly warm intake air, a heating element configuration that preferentially heats the side wall over the top wall to melt and atomize vaporization media, and improved air pathway management to enhance vapor pickup, along with structural enhancements for media flow and anti-leak structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a heating coil is used to atomize vaporization media, then atomization can be achieved, but the warming of intake air is inconsistent and heat available for atomization is reduced
Solution Approach 1:
The heating element is segmented into distinct functional zones: a first heating zone for warming intake air and a second heating zone for atomizing vaporization media. This segmentation allows independent optimization of each function, ensuring consistent air warming while maintaining effective atomization heat availability.
Solution Approach 2:
Different regions of the heating element are assigned different thermal properties and functions. The first zone has characteristics optimized for gradual air warming, while the second zone has characteristics optimized for high-temperature atomization. This local quality differentiation resolves the contradiction by providing consistent warming in one area while preserving heat for atomization in another.
2Area of stationary object
If traditional heating coils are used, then atomization occurs in a limited area, but the vaporization footprint is restricted
Solution Approach 1:
The heating element extends in multiple spatial dimensions with a first zone for air warming and a second zone for atomization. This dimensional expansion creates a larger vaporization footprint while maintaining efficient vapor delivery through the extended heating surface area that contacts both air and vaporization media.
3Adaptability or versatility
If high-viscosity vaporization media such as waxes are used, then diverse media can be vaporized, but the media does not substantially flow at room temperature
Solution Approach 1:
The first heating zone performs preliminary action by warming the vaporization media before it reaches the atomization zone. This pre-heating reduces the viscosity of high-viscosity media like waxes, enabling them to flow to the atomizer and ensuring consistent media delivery while maintaining versatility in media type selection.

Implementation Method 1
The heating element heats the media M so that it is atomized-dispersed into very fine droplets or particles
Implementation Method 2
the heating element is configured to, when actuated, melt but not atomize vaporization media upon the top surface so that the melted vaporization media flows off of the top surface
Implementation Method 3
the heating element is configured to warm intake air when at the heating coil

AI summary
A personal vaporizer includes a heating element having a generally upside-down cup shape. An air warming space is defined within the cup shape, and intake air is delivered into the air warming space. Vaporization media is delivered adjacent a top wall of the heating element. The heating element warms the vaporization media so that it flows downwardly along a side wall of the heating element. The side wall of the heating element is heated sufficient to atomize the vaporization media. Warmed intake air from the air warming space is drawn through the atomized media, forming a vapor that can be inhaled by a user.
