Double-Walled Vaporizer Capsule for Cannabis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vaporizer capsules for cannabis lack hygiene and precise dosage control, as they are prone to contamination and diffusion of active ingredients, and manual filling can lead to inconsistent dosages and mixing issues.
Innovation Solution
A double-walled capsule design with separate cavities for the active ingredient and an excipient, where the excipient can enhance or interact with the active ingredient, and a vaporizable chemical reactant can be used to release heat, ensuring hermetic sealing and controlled vaporization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual filling is used for capsules, then ease of manufacture is improved, but manufacturing precision deteriorates due to inconsistent dosages and mixing issues
Solution Approach 1:
The capsule is divided into multiple separate compartments (first cavity for active ingredient, second cavity for excipient) that are sealed independently. This segmentation allows each compartment to be filled and sealed separately, eliminating cross-contamination and dosage mixing issues while maintaining manufacturing precision.
Solution Approach 2:
The inner cavity structures are nested within the outer capsule body, with the first and second cavities positioned concentrically or adjacently within the same capsule housing. This nested design allows compact integration of multiple functional compartments while maintaining hermetic sealing of each.
2Device complexity
If single-walled capsule design is used, then device complexity is reduced, but reliability deteriorates due to contamination and diffusion of active ingredients
Solution Approach 1:
The capsule wall is segmented into double-walled structures with distinct inner and outer walls forming separate cavities. This segmentation creates hermetic barriers that prevent contamination and diffusion of active ingredients, significantly improving reliability without excessive complexity.
Solution Approach 2:
The double-walled structure is applied locally at critical sealing zones and compartment boundaries where contamination risk is highest, rather than uniformly throughout the entire capsule. This targeted approach improves reliability at critical points while minimizing overall structural complexity.
3Temperature
If combustion is used for vaporization, then temperature is sufficient to convert carboxylic acids, but object-generated harmful factors increase due to toxic substances and destroyed cannabinoids
Solution Approach 1:
The vaporization temperature parameter is precisely controlled and reduced from combustion levels (800-900°C) to a lower range (185-210°C) that is sufficient to vaporize cannabinoids and convert carboxylic acids without generating toxic combustion byproducts like tar, benzene, or carbon monoxide.
Solution Approach 2:
The patent converts the previously harmful high-temperature combustion process into a beneficial low-temperature vaporization process. By reducing the temperature parameter, the system eliminates harmful byproducts while still achieving the necessary chemical conversion of carboxylic acids to cannabinoids and effective vaporization for inhalation.
4Reliability
If hermetic sealing is implemented, then reliability is improved by preventing contamination, but device complexity increases due to double-walled structure
Solution Approach 1:
The capsule is segmented into distinct sealed compartments with hermetic barriers between them. This segmentation allows each cavity to be independently sealed, ensuring reliability and preventing cross-contamination while maintaining a relatively simple overall structure that is easy to manufacture.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides improved hygiene, accurate dosing, and extended shelf life by preventing contamination and allowing for precise control over the vaporization process, ensuring effective delivery of cannabis compounds without the production of harmful byproducts.
Implementation Method 1
a vaporizable chemical reactant can be used to release heat
Implementation Method 2
a temperature of over 185 degrees Celsius should be aimed for. The carboxylic acids and terpenes are almost completely dissolved out at a temperature of 210 degrees Celsius without the plant material burning
Implementation Method 3
Vaporizing the active ingredient, e.g. a cannabis flower, offers further decisive advantages
