Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a vertical air inlet passage is arranged at the bottom of the vaporizer, then the structure is simple and easy to manufacture, but vapor flows back through the air inlet passage and electrodes into the battery assembly causing moisture condensation and short circuits
Solution Approach 1:
The air inlet system is segmented into separate components: an air inlet chamber at the bottom of the vaporizing device, air inlet passages in the housing wall, and a vapor outlet tube. This segmentation prevents direct vertical communication between the air inlet and vapor outlet, eliminating the backflow path while maintaining manufacturing simplicity.
Solution Approach 2:
The air inlet chamber acts as an intermediary space between the air inlet passages and the vaporizing chamber. It buffers the incoming air and prevents vapor from flowing back through the air inlet passages into the battery assembly, thus protecting against moisture condensation and short circuits.
2Device complexity
If the air inlet passage is in vertical communication with the vaporizing chamber and vapor outlet tube, then the device complexity is reduced, but moisture condenses on the battery assembly receiving opening and causes corrosion
Solution Approach 1:
The passage system is divided into separate functional segments: air inlet passages for air supply, an air inlet chamber for buffering, and a vapor outlet tube for vapor discharge. This segmentation eliminates direct vertical communication that causes moisture backflow to the battery assembly, preventing corrosion while maintaining reasonable device complexity.
Solution Approach 2:
The air inlet chamber serves as an intermediary buffer zone that prevents vapor from reaching the air inlet passages and flowing back to the battery assembly. This intermediary structure effectively blocks the harmful moisture transport path without significantly increasing device complexity.
3Ease of manufacture
If positive and negative electrodes are not sealed, then the manufacturing process is simpler, but vapor flows back through electrode gaps into the battery assembly causing short circuits
Solution Approach 1:
The air inlet chamber acts as an intermediary barrier between the vaporizing chamber and the battery assembly. Even though the electrodes are not sealed and gaps exist between positive and negative electrodes, the air inlet chamber prevents vapor from flowing back through these gaps into the battery assembly, thus preventing short circuits while maintaining simple electrode assembly manufacturing.
Solution Approach 2:
The air inlet chamber provides beforehand cushioning by creating a buffer zone that captures and contains any vapor that might attempt to flow back through the unsealed electrode gaps. This prior cushioning prevents the vapor from reaching the battery assembly and causing harmful effects.
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 design effectively prevents moisture from causing short circuits and corrosion, improving user experience by ensuring more e-cigarette liquid is vaporized and reducing leakage, while maintaining a strong suction for efficient vapor production.
Implementation Method 1
a heating coil wound around the middle of the liquid guiding strip... the e-cigarette liquid in the liquid absorbing chamber is absorbed by the liquid guiding strip and guided to the heating coil to be heated and vaporized, thus producing vapor of the e-cigarette in the vaporizing chamber
Implementation Method 2
The e-cigarette liquid in the liquid absorbing chamber is absorbed by the liquid guiding strip and guided to the heating coil
Implementation Method 3
the vapor flows back, the moisture in the vapor will be condensed in the air inlet chamber, therefore preventing the moisture from flowing back and being condensed in the receiving opening of the battery assembly
