Vapour Provision Component Boundary Wall for Rigid Aperture Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vapour provision systems face issues with fluid leaks through apertures, leading to free liquid in the vapour chamber, which can cause damage and poor quality aerosol production.
Innovation Solution
The use of rigid bodies to form the boundary wall between the reservoir and vapour chamber, with apertures defined by these bodies, ensures consistent aperture size and shape, minimizing liquid leakage and maintaining efficient fluid flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If apertures are provided in the boundary wall for fluid flow, then fluid delivery to the vapour generator is enabled, but fluid leakage through the apertures occurs causing free liquid in the vapour chamber
Solution Approach 1:
The boundary wall incorporates a porous wicking element that allows controlled fluid transport through capillary action while preventing uncontrolled leakage. The porous structure enables selective permeability - allowing vapor and controlled fluid flow while blocking excess liquid passage.
Solution Approach 2:
A wicking element acts as an intermediary between the reservoir and vapour chamber, mediating fluid transport. The wick absorbs and transports fluid through capillary action, controlling the flow rate and preventing direct liquid leakage while maintaining adequate fluid supply to the heating element.
2Ease of manufacture
If the boundary wall structure is made flexible to accommodate assembly variations, then ease of manufacture is improved, but aperture size consistency deteriorates leading to increased leakage
Solution Approach 1:
The invention changes the physical parameters of the boundary wall by using a rigid structure with precisely controlled aperture dimensions. This ensures consistent aperture size and shape across manufacturing variations, maintaining reliable fluid flow control while preventing leakage through dimensional stability.
3Productivity
If the aperture size is increased to improve fluid flow, then productivity is improved, but fluid leakage increases causing free liquid in the vapour chamber
Solution Approach 1:
The porous wicking element provides a large effective surface area for fluid absorption and transport, enabling high fluid flow rates through capillary action without creating large open apertures that would cause uncontrolled leakage. The porous structure maintains small pore sizes while achieving high productivity.

Function Achieved in This Case
This approach reduces fluid leakage, maintains consistent fluid flow, and prevents damage to the system, ensuring high-quality aerosol production by maintaining a stable liquid supply to the vapour generator.
Implementation Method 1
one or more openings or apertures are provided in the wall by which fluid can travel from the reservoir to the vapour generator, often by capillary action in a porous wicking element extending through the aperture

AI summary
A component for a vapour provision system comprises a boundary wall separating a reservoir for holding a fluid from a chamber for housing a vapour generator, the boundary wall comprising two or more adjacent rigid bodies sealed to one another; and a tubular aperture in the boundary wall providing a fluid transport path from the reservoir to the vapour generator; wherein the aperture is defined between the adjacent rigid bodies, the rigid bodies enclosing a perimeter of the aperture along at least part of aperture's length.
