Ionic Vaporizer Cartridge with Resistive Heating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vaporizer devices face challenges in controlling the temperature of heating elements, leading to hot spots and the formation of undesirable chemical components in the inhalable aerosol, and issues with thermal transport due to non-optimal placement of heating elements.
Innovation Solution
The vaporizer cartridges utilize the resistance of the vaporizable material itself for heating, eliminating the need for a separate heating element and incorporating a reservoir, airflow tube, and electrodes to vaporize the liquid material through a potential difference, with a wicking element to draw material into the airflow passageway for efficient vaporization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a separate heating element is used to vaporize the material, then vaporization can be achieved, but temperature control becomes difficult leading to hot spots and formation of undesirable chemical components
Solution Approach 1:
The patent removes the separate heating element from the system and replaces it with electrodes that directly interact with the ionic vaporizable material. This extraction of the heating function and integration with the material itself enables precise temperature control through electrical potential application, preventing hot spots and decomposition into harmful chemicals.
Solution Approach 2:
The heating function is merged with the vaporizable material by using the material's own ionic properties. The electrodes apply electrical potential directly to the ionic material, causing it to heat and vaporize in a controlled manner. This merging eliminates the temperature control issues associated with separate heating elements while preventing formation of harmful byproducts.
2Temperature
If a heating element is placed in the vaporization chamber, then vaporization occurs, but thermal transport is insufficient due to non-optimal placement
Solution Approach 1:
The ionic vaporizable material serves its own heating function by conducting electrical current between the electrodes. The material's ionic properties enable it to self-heat through resistive heating when voltage is applied, eliminating the need for externally placed heating elements and their associated thermal transport problems.
Solution Approach 2:
The mechanical heating element system is replaced with an electrical field-based system. Instead of using a physical heating element that requires optimal thermal contact and placement, the patent uses electrical potentials applied through electrodes to directly energize the ionic material, achieving superior and more uniform thermal transport.
3Reliability
If traditional heating methods are used, then vaporization can occur, but consistent temperature control is difficult resulting in variable vaporization quality
Solution Approach 1:
The patent changes the fundamental parameter for heating from thermal conduction (heating element to material) to electrical energy input (electrodes to ionic material). This parameter change enables precise and consistent temperature control through electrical potential application, ensuring reliable and repeatable vaporization quality without the variability inherent in traditional heating methods.
