Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic cigarette atomizers face issues with heating wires easily getting scorched, producing burnt flavor, low energy efficiency, and tobacco tar leakage, while ultrasonic atomizers produce smoke with larger particle sizes resulting in poor smoking taste.
Innovation Solution
An electronic cigarette atomizer design featuring an ultrasonic atomization piece in contact with a tobacco tar storage piece, where the smoke is directed through an airflow passage in the reverse direction to prevent large-particle smoke inhalation, using an elastic fixing base and pressure cover for stability and electric contact, and tobacco tar guide body to prevent leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If heating wires are used to heat tobacco tar, then the atomization function is achieved, but the heating wires are easily scorched and produce burnt flavor
Solution Approach 1:
The patent replaces the thermal field (heating wire) with an ultrasonic vibration field (atomization piece). The ultrasonic atomization piece vibrates at high frequency to atomize tobacco tar through mechanical vibration rather than thermal heating, eliminating the scorching and burnt flavor issues associated with high-temperature heating wires.
2Reliability
If high temperature heating is used for atomization, then the atomization effect is achieved, but the energy efficiency is low and the electronic cigarette becomes hot
Solution Approach 1:
The patent substitutes thermal energy conversion with ultrasonic vibration energy conversion. The ultrasonic atomization piece converts electrical energy directly into mechanical vibration energy, which then atomizes the tobacco tar through physical vibration, bypassing the inefficient thermal conversion process and reducing energy loss and device temperature.
3Object-generated harmful factors
If ultrasonic atomization is used, then the smoking taste is improved, but smoke molecules with larger particle sizes are produced resulting in poor smoking taste
Solution Approach 1:
The patent employs dynamic ultrasonic vibration at high frequency to atomize tobacco tar. The continuous vibration creates dynamic forces that break down tobacco tar into fine particles, controlling the particle size distribution to achieve optimal smoking taste by preventing excessive particle aggregation.
Solution Approach 2:
The ultrasonic atomization piece utilizes high-frequency mechanical vibration to atomize the tobacco tar. This mechanical vibration approach produces finer and more uniform particle sizes compared to static or thermal methods, improving smoking taste by creating appropriately sized aerosol particles.
4Device complexity
If simple fixing structure is used for ultrasonic atomization piece, then the device complexity is reduced, but the ultrasonic atomization piece is prone to idle vibration and poor contact stability
Solution Approach 1:
The patent uses an elastic pressure cover made of flexible material to fix the ultrasonic atomization piece. This elastic structure provides flexible contact that adapts to vibrations while maintaining stable pressure contact, preventing idle vibration and ensuring reliable electrical and mechanical connection without requiring complex rigid fixing mechanisms.
