Spring-Sealed Vaporizer Chamber Assembly for Leakage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vaporization devices face leakage issues due to liquid from the liquid chamber seeping into the vaporization chamber, potentially damaging components and affecting performance, especially when not in use or under barometric pressure changes.
Innovation Solution
An assembly comprising an inner tube slidably supported within an outer tube, with a spring mechanism that allows the vaporization chamber's aperture to be sealed by a cover's skirt, transitioning between open and closed states to prevent liquid leakage, featuring a stopper and ledges to constrain movement and control the spring's compression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vaporization chamber aperture remains open to allow vaporization operation, then the device can function properly, but liquid may leak into the vaporization chamber damaging components
Solution Approach 1:
The cover is pre-positioned to cover the aperture and prevent liquid leakage before the device is activated. The spring mechanism is pre-compressed to provide immediate sealing action when the device is stored or not in use, eliminating the need for separate capping operations.
Solution Approach 2:
The cover is made movable between open and closed positions through the spring mechanism. The dynamic positioning allows the aperture to be open during operation for proper vaporization function, and closed during storage to prevent liquid leakage and protect components.
2Reliability
If a cover is added to seal the aperture, then liquid leakage is prevented, but the device structure becomes more complex
Solution Approach 1:
The cover is integrated with the inner tube assembly, and the spring mechanism is incorporated within the same structural envelope. The cover, spring, and tube components work as a unified system rather than separate additions, minimizing overall structural complexity while achieving reliable sealing.
Solution Approach 2:
The cover is nested within the outer tube structure, and the spring is nested between the cover and the vaporization chamber. This nested arrangement allows multiple functional components to occupy overlapping spatial volumes, reducing the overall device footprint and structural complexity.
3Reliability
If the spring is compressed to seal the aperture, then liquid leakage is prevented, but the spring may exert excessive force on components
Solution Approach 1:
The spring force is applied locally at specific contact points between the spring and the cover/tube structure. The force distribution is optimized to provide adequate sealing pressure at the aperture while avoiding excessive concentrated loads that could damage components. The ledges and stops create localized force transfer paths.
Solution Approach 2:
The spring is pre-compressed to a controlled degree during assembly, establishing a baseline sealing force before the device is activated. This preliminary compression ensures the aperture is sealed during storage without subjecting components to excessive force, as the spring maintains a balanced compressed state rather than full compression.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively prevents liquid leakage into the vaporization chamber, ensuring the heating element and control components remain protected, allowing for safe storage and use by maintaining a seal until the device is ready for operation.
Implementation Method 1
A spring is disposed in a compressed state between the plate and an interior of the outer tube
Implementation Method 2
an inner tube slidably supported within an outer tube by a stopper disposed on a first ledge extending inwardly within the outer tube
Implementation Method 3
the plate is constrained from moving out of the outer tube by having an outermost dimension that is larger than an inner dimension of a second ledge that extends inwardly within the outer tube

AI summary
An assembly for preventing leakage in a vaporization device comprises an inner tube slidably supported within an outer tube, and a plate fixedly attached at a first end of the inner tube. A vaporization chamber having at least one aperture disposed therethrough is fixedly attached within the outer tube. A spring is disposed in a compressed state between the plate and an interior of the outer tube, and a cover is fixedly attached at a second end of the inner tube, the cover having a skirt. In a first state the plate is held by the compressive force of the spring at a first end of the outer tube so that the aperture is not covered by the skirt, and in a second state the plate is pushed into the outer tube by further compressing the spring so that the aperture is covered by the skirt.
