Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the liquid storage cotton is directly placed in the liquid storage ring without a fixing structure, then the assembly is simple, but the liquid storage cotton easily falls off when the atomization core is pulled out, causing contamination and inconvenience
Solution Approach 1:
The liquid storage ring is divided into an upper ring and a lower ring that are detachably connected, allowing the liquid storage cotton to be securely positioned between them. This segmentation enables both easy assembly and reliable retention of the liquid storage cotton.
Solution Approach 2:
The liquid storage cotton is nested between the upper and lower liquid storage rings, with the rings fitting together to form a complete structure. This nested arrangement secures the liquid storage cotton while maintaining assembly simplicity.
2Reliability
If the ultrasonic atomization sheet is compressed by an elastic conductive sheet to conduct electricity, then the electrical connection is achieved, but the compression effect must be weakened to avoid affecting oscillation amplitude, resulting in poor contact and unreliable conductivity
Solution Approach 1:
A conductive gel is introduced as an intermediary substance between the elastic conductive sheet and the ultrasonic atomization sheet. The conductive gel enhances electrical conductivity while requiring minimal compression, thus preserving the oscillation amplitude of the atomization sheet.
Solution Approach 2:
The use of conductive gel changes the electrical contact parameters, allowing for better conductivity with reduced mechanical compression. This parameter change enables reliable electrical connection without compromising the atomization sheet's oscillation characteristics.
3Reliability
If the electrode layers on the ultrasonic atomization sheet are connected to the power supply electrode by welding, then the electrical connection is secure, but the high temperature during welding causes depolarization and loss of high-frequency oscillation performance, shortening service life
Solution Approach 1:
The welding process is replaced with a mechanical connection system consisting of conductive gels and elastic conductive sheets. This substitution eliminates high-temperature exposure, preventing depolarization of the ultrasonic atomization sheet while maintaining secure electrical connection.
Solution Approach 2:
Conductive gels serve as intermediaries between the electrode layers and power supply electrodes, providing reliable electrical connection without requiring high-temperature welding. This intermediary approach preserves the ultrasonic atomization sheet's polarized structure and extends service life.
4Ease of operation
If the atomization core is pulled out when the ultrasonic atomization sheet is parallel to the length of the electronic cigarette, then the atomization core can be removed, but a small amount of tobacco tar is taken out of the liquid bin, causing leakage and staining
Solution Approach 1:
A liquid absorber is pre-positioned at the liquid outlet end of the liquid bin to absorb tobacco tar before the atomization core is removed. This preliminary action prevents tobacco tar leakage and staining during the removal process.
Solution Approach 2:
The liquid absorber acts as an intermediary between the liquid bin and the external environment during atomization core removal. It captures and retains tobacco tar, preventing it from leaking out and staining the user's hands or surrounding areas.
