Vaporiser Lid Protrusion for Uniform Herbal Sachet Heating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing herbal vaporisers require manual preparation and loading of loose herbal material, which can be messy and time-consuming, and sachets with flexible structures like teabags may not heat evenly due to irregular placement.
Innovation Solution
A vaporiser device with a lid featuring a protrusion that pushes a sachet of herbal material into a heating chamber, ensuring even heating and eliminating the need for manual manipulation, using a U-shaped chamber and corresponding protrusion for optimal sachet placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If loose herbal material is manually loaded into the heating chamber, then the device can be used with flexible herbal material, but the process is time-consuming and messy
Solution Approach 1:
The herbal material is pre-loaded into a sachet before use, which is then simply inserted into the heating chamber. This preliminary preparation eliminates the need for users to manually load loose material during the vaping process, significantly reducing the time and mess associated with loading.
Solution Approach 2:
The sachet is designed as a disposable component that is pre-filled with herbal material. After use, the entire sachet is discarded, eliminating the need for cleaning and preparation of loose material. This approach trades the reusability of loose material for the convenience of disposable pre-prepared units.
2Volume of moving object
If sachet is rolled or folded for placement in heating chamber, then it can fit in the chamber, but the paper becomes interspersed with herbal material resulting in suboptimal consumption
Solution Approach 1:
The sachet is designed to be inserted in a specific orientation and then flattened against the heating surface, transitioning from a three-dimensional rolled/folded state to a two-dimensional compressed state. This dimensional change allows the sachet to fit within the heating chamber while maintaining contact with the heating surface without requiring manipulation that would intersperse paper with herbal material.
Solution Approach 2:
The sachet structure is designed with specific local properties: the herbal material is contained within a sealed pouch that has a specific texture and flexibility. The pouch is designed to conform to the heating surface when pressed, ensuring uniform contact and heating while keeping the herbal material contained and separated from the paper structure.
3Ease of operation
If flexible sachet is placed in heating chamber without protrusion, then loading is simple, but heating is uneven due to irregular placement
Solution Approach 1:
The protrusion acts as an intermediary mechanical element between the lid and the sachet. When the lid is closed, the protrusion automatically engages with the sachet and applies controlled pressure to flatten and position it against the heating surface. This intermediary mechanism ensures uniform heating without requiring complex user manipulation or precision in sachet placement.
Solution Approach 2:
The system is designed so that the act of closing the lid automatically performs the function of positioning and flattening the sachet through the protrusion mechanism. The user simply needs to close the lid, and the protrusion self-adjusts to apply the necessary pressure and positioning, eliminating the need for manual manipulation while ensuring uniform heating.
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
Facilitates easy and efficient loading of herbal material, ensuring uniform heating and improved vaporisation performance by pinning the sachet against the heating surface, enhancing user convenience and vaporisation efficiency.
Implementation Method 1
heat a herbal material to a pre-determined temperature in a heating chamber in order to release an aerosol for consumption
Implementation Method 2
heated only sufficiently for the active ingredient to boil and be released as a consumable vapour
Implementation Method 3
the lid comprises a protrusion on an underside thereof which extends into said internal area in said closed position
Implementation Method 4
the conduction of heat from the surface of the heating chamber may not reach it all, or may not heat it all in a regular manner
