Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a linear heating wire is used to heat e-liquid, then the structure is simple and easy to manufacture, but the atomizing temperature is non-uniform causing different atomizing particle sizes
Solution Approach 1:
The heating body is segmented into multiple heating sections arranged in an array, where each heating section contains multiple heating elements positioned at different locations. This segmentation allows each heating element to independently heat a specific region of e-liquid, ensuring uniform temperature distribution across the entire atomization surface and producing consistent atomizing particle sizes.
Solution Approach 2:
Different heating elements are positioned at different locations on the atomization surface to provide localized heating. Each heating element targets a specific region, ensuring that every area of e-liquid receives appropriate heat treatment. This local quality approach maintains temperature uniformity across the surface while preserving the simplicity of individual heating element construction.
2Volume of moving object
If a spring-shaped heating wire is used, then the heating structure is compact, but only e-liquid near the heating wire can be heated effectively
Solution Approach 1:
The heating structure transitions from a one-dimensional linear heating wire to a two-dimensional array of heating elements distributed across the atomization surface. This dimensional expansion allows heat to be applied across a broader area, effectively heating a larger quantity of e-liquid while maintaining a compact overall structure through the planar arrangement of heating sections.
3Power
If heating is concentrated at one location, then the heating power is high, but the atomizing temperature becomes non-uniform
Solution Approach 1:
The total heating power is segmented and distributed across multiple heating elements arranged in an array. Each heating element contributes to the overall heating effect, collectively providing high power while distributing heat uniformly across different locations. This prevents temperature concentration at a single point and ensures uniform atomizing temperature throughout the e-liquid.
