Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic smoking devices, such as e-cigarettes, face limitations in aerosol generation due to the simplicity of their heating coils, which can result in delayed vapor production and inconsistent vaping experiences.
Innovation Solution
The use of a common heating coil formed by two heating wires with different physical parameters, such as diameter and material, wound together to create a staggered configuration that enhances heat transfer characteristics and reduces delay in aerosol production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single heating wire is used in the heating coil, then the device complexity is reduced, but the aerosol generation speed and efficiency deteriorate
Solution Approach 1:
The heating coil is segmented into multiple heating wires (at least two) with different physical parameters, where each wire contributes differently to heat generation. This segmentation allows for optimized heat transfer characteristics and faster aerosol production without requiring an overly complex single-wire design
Solution Approach 2:
Different portions of the heating coil have different properties through using heating wires with varying physical parameters (diameter, material, length, winding diameter). This creates local quality variations that optimize heat transfer at different locations, improving overall aerosol generation efficiency
2Reliability
If heating wires with different physical parameters are used, then the heat transfer characteristics and surface area for liquid contact are improved, but the manufacturing precision requirements increase
Solution Approach 1:
The invention deliberately changes physical parameters of heating wires (diameter, material composition, length, winding diameter) to create different thermal properties. These parameter variations are designed to improve heat transfer and liquid contact surface area, with the understanding that they enable more reliable and consistent vaping performance
3Productivity
If the heating coil structure is simplified, then the ease of manufacture is improved, but the heating speed and aerosol production efficiency deteriorate
Solution Approach 1:
Rather than creating a single complex heating wire, the solution segments the heating function across multiple wires with different properties. This achieves faster heating and better aerosol production while maintaining relatively simple manufacturing processes for each individual wire component
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
This configuration improves aerosol generation by providing a greater surface area for liquid contact and faster heating, resulting in a more complex and efficient vaping experience compared to single-wire coils.
Implementation Method 1
The atomizer vaporizes or atomizes liquid supplied from a reservoir and provides vaporized or atomized liquid as an aerosol
Implementation Method 2
