Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vapor generating devices for inhalation, such as those that heat tobacco, often produce inconsistent vapor levels and flavor delivery due to unreliable capsule usage, leading to an inconsistent user experience.
Innovation Solution
A plug of vaporizable material with a frusto-conical cavity is designed to control vapor release speed and duration by varying the thickness of the material, reducing draw resistance and enhancing flavor consistency, with the cavity's angle and thickness optimized for specific vapor generation profiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a plug of vaporisable material is heated to generate vapor, then vapor is produced for inhalation, but the vapor levels and flavor delivery are inconsistent
Solution Approach 1:
The plug incorporates a cavity with frusto-conical shape that creates localized variations in material thickness. The material is deliberately made thinner at certain locations (near the cavity) and thicker at others, allowing different regions to vaporize at different rates and times, thereby achieving consistent overall vapor delivery despite non-uniform local thickness
Solution Approach 2:
The invention changes the geometric parameters of the plug by introducing a cavity with specific frusto-conical geometry. This modifies the material distribution and thickness profile, which directly controls the vaporization rate and timing, resulting in improved vapor delivery consistency
2Duration of action of moving object
If the plug material is heated to release vapor, then vapor is generated, but the speed of vapor release and duration are difficult to control
Solution Approach 1:
The frusto-conical cavity creates zones of different material thickness within the plug. Thinner regions vaporize faster and earlier, while thicker regions vaporize slower and later, thereby controlling both the speed and duration of vapor release in a predictable sequence
Solution Approach 2:
The cavity geometry is pre-designed to anticipate the desired vapor release profile. By shaping the cavity with specific frusto-conical dimensions before use, the vaporization timeline is predetermined, ensuring consistent duration and speed characteristics across multiple uses
3Ease of operation
If a plug of vaporisable material is used in a heating device, then vapor is generated, but draw resistance is high
Solution Approach 1:
The cavity creates an internal void space within the plug structure, effectively reducing the material density and creating a more open, porous-like configuration. This allows vapor to flow more easily through the plug with reduced resistance, improving draw characteristics
