Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a spiral resistance wire is used as the heating element, then the heating element can be constructed with simple structure, but the atomization effect becomes uneven and deteriorates as the heating wire length increases
Solution Approach 1:
The patent employs a porous heating element structure where the heating wire is embedded within a porous wicking material. This porous configuration allows liquid to be uniformly distributed throughout the heating element via capillary action, ensuring consistent atomization across the entire heating surface while maintaining a relatively simple overall structure.
Solution Approach 2:
The heating element is constructed as a composite of the resistance wire and wicking material, combining the electrical heating function of the wire with the liquid transport and distribution function of the porous wicking material. This composite structure enables uniform liquid distribution and consistent atomization while keeping the design straightforward.
2Area of stationary object
If the heating wire length is increased to cover more liquid, then the heating coverage area increases, but the temperature drops significantly along the wire length
Solution Approach 1:
The porous wicking material distributes liquid uniformly across the entire heating surface through capillary action, ensuring that liquid is available at all heating zones simultaneously. This maintains consistent temperature distribution across the extended heating area without significant temperature drop along the wire length.
Solution Approach 2:
The porous structure creates equipotential liquid distribution across the heating surface, ensuring that liquid is evenly supplied to all regions of the heating element. This uniform liquid distribution compensates for temperature gradients that would otherwise occur in longer heating wires, maintaining consistent atomization temperature across the entire heating area.
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
The solution achieves uniform atomization and improved taste by ensuring all parts of the porous body are heated evenly, preventing large atomized particles and enhancing the overall atomizing effect.
Implementation Method 1
The porous heating film can further enable the porous body to be heated uniformly, therefore the temperature of the porous body evenly increases at all part
Implementation Method 2
a porous body comprising an atomizing surface and a liquid absorbing surface
Implementation Method 3
When activated, the resistance wire quickly heats up thus turning the liquid absorbed by the wicking material into a vapor, which is then inhaled by the user
