Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If heating wires are used to heat tobacco tar, then the atomizer can generate smoke, but the heating wires are scorched easily to produce burnt flavor and the temperatures are transferred to outer walls making the electronic cigarette hot
Solution Approach 1:
The patent replaces the traditional heating wire (thermal field system) with ultrasonic vibration (mechanical field system). The ultrasonic atomization component generates high-frequency vibrations that directly atomize the tobacco tar liquid through mechanical energy, eliminating the need for high-temperature heating and thus preventing burnt flavor and excessive heat transfer to the outer walls.
Solution Approach 2:
The patent changes the working parameter from high temperature (heating wire operation at several hundred degrees) to high frequency vibration (ultrasonic frequency). This parameter transformation allows the atomization process to occur at much lower temperatures, preventing the harmful effects of thermal scorching while maintaining effective smoke generation.
2Productivity
If heating wires are used at high temperatures, then atomization can occur, but energy efficiency is low and smoking taste is poor
Solution Approach 1:
The patent replaces thermal energy conversion with mechanical vibration energy conversion. Instead of using electrical energy to heat the tobacco tar (low efficiency thermal transfer), the ultrasonic atomization component directly converts electrical energy to mechanical vibration energy, which efficiently atomizes the liquid through cavitation and mechanical disruption, significantly improving energy efficiency and smoke quality.
3Quantity of substance
If tobacco tar is stored in the liquid storage body, then the atomizer can maintain liquid supply, but excessive tobacco tar accumulates on the atomization surfaces causing slow start and small smoke volume
Solution Approach 1:
The patent segments the liquid storage function from the atomization function. The liquid storage body stores tobacco tar separately, while the ultrasonic atomization component performs atomization. The guided liquid delivery system ensures controlled transfer of liquid from storage to atomization surface, preventing excessive accumulation and ensuring rapid, efficient atomization when needed.
Solution Approach 2:
The patent introduces a liquid guide structure as an intermediary between the liquid storage body and the atomization surface. This intermediary component controls the flow and distribution of tobacco tar liquid, ensuring optimal liquid supply to the atomization surfaces without overaccumulation, thereby maintaining fast response and adequate smoke volume.
4Productivity
If heating wires are used, then tobacco tar can be vaporized, but the atomizers are prone to tobacco tar leakage
Solution Approach 1:
The patent replaces thermal vaporization with mechanical ultrasonic atomization. The ultrasonic vibrations create intense mechanical disruption of the liquid at the atomization surface, generating fine aerosol particles directly without requiring high temperatures. This mechanical approach prevents the thermal degradation and capillary overflow issues that cause leakage in heating-based systems.
