Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a heating wire is directly immersed into the e-liquid to heat and atomize it, then the heating function is achieved, but the quality of the e-liquid degrades due to direct contact
Solution Approach 1:
The patent introduces an intermediary heating structure that indirectly heats the e-liquid without direct contact. The heating wire is enclosed within a heating assembly that transfers heat to the e-liquid through conduction and convection, preventing direct contact between the heating wire and e-liquid while maintaining effective heating function
Solution Approach 2:
The heating system is segmented into distinct components: the heating wire is separated from the e-liquid contact zone by placing it inside a dedicated heating assembly structure, allowing independent optimization of heating efficiency and e-liquid quality preservation
2Productivity
If microwave energy is increased to improve heating efficiency, then atomization performance improves, but energy loss increases without effective utilization
Solution Approach 1:
The microwave source is nested within a multi-layer shielding structure consisting of a shielding sleeve and shielding nets. This nested configuration confines microwave energy within the heating region, preventing energy leakage while maintaining high heating efficiency and improving overall energy utilization
Solution Approach 2:
The shielding structure that might seem to restrict microwave propagation actually converts potential energy loss into beneficial concentrated heating. The reflected and confined microwave energy is redirected to enhance heating efficiency rather than being lost, turning what could be harmful radiation loss into useful heating energy
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 solution effectively heats and atomizes e-liquid without degrading it, improving heating efficiency and maintaining e-liquid quality, while being environmentally friendly.
Implementation Method 1
the microwave source emits microwave; the microwave is released into the shielding sleeve to heat and atomize e-liquid adsorbed on the strip of cotton
Implementation Method 2
the first shielding net and the second shielding net are disposed on two ends of the strip of cotton in the shielding sleeve so as to hold the microwave emitted by the microwave source in the shielding sleeve
Implementation Method 3
the microwave source emits microwave; the microwave is released into the shielding sleeve to heat and atomize e-liquid
