Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vaporizer devices face challenges in efficiently delivering vaporizable materials to the heating element due to limitations in wick design, which can lead to uneven liquid distribution, manufacturing complexity, and increased volume occupancy, among other issues.
Innovation Solution
A cartridge for a vaporizer device featuring a heating element with a capillary structure comprising rigid portions that create a capillary gap to draw vaporizable material from a reservoir to a heater region, allowing for controlled capillary pressure and efficient vaporization, with optional air flow across the heater region for evaporation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wick is used to deliver liquid to the heating element, then the device can transport vaporizable material, but the wick can become clogged with resinous material and require frequent cleaning or replacement
Solution Approach 1:
The patent removes the wick component entirely from the system. Instead of using a wick to transport the vaporizable material, the invention employs capillary channels formed within the heating element structure itself to deliver the liquid directly to the heating region, eliminating the clogging issue associated with traditional wicks
Solution Approach 2:
The patent introduces capillary channels as an intermediary structure between the liquid reservoir and heating element. These channels provide a controlled pathway for liquid transport through capillary action, replacing the function previously performed by the wick while avoiding its drawbacks
2Productivity
If a capillary gap is used to draw vaporizable material, then material delivery is improved, but the heating element structure becomes more complex
Solution Approach 1:
The patent merges the liquid delivery function with the heating element structure by forming capillary channels within the heating element itself. This integration eliminates the need for separate delivery mechanisms while maintaining effective vaporizable material transport through capillary action
Solution Approach 2:
The patent utilizes the porous or channelled structure of the heating element to enable capillary flow of the vaporizable material. The capillary channels provide controlled liquid transport through surface tension and capillary pressure without requiring additional mechanical components
