Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the electronic cigarette is designed with a compact and small shape, then the portability and convenience are improved, but the internal structure becomes cramped leading to e-liquid leakage and poor liquid supply
Solution Approach 1:
The internal structure is divided into separate functional regions: a first cavity for the e-liquid storage tank and a second cavity for the vaporization assembly, with a communication channel connecting them. This segmentation allows each component to be optimized independently while maintaining compact overall dimensions, resolving the contradiction between small size and reliable liquid supply.
Solution Approach 2:
A communication channel acts as an intermediary between the e-liquid storage tank and the vaporization assembly, providing a controlled pathway for e-liquid flow. This intermediary structure ensures reliable liquid supply while maintaining compact design by optimizing the flow path within limited space.
2Reliability
If the e-liquid storage tank is sealed to prevent leakage, then liquid containment is improved, but air pressure imbalance occurs leading to poor liquid supply
Solution Approach 1:
The communication channel serves as a mediator that allows controlled air exchange between the e-liquid storage tank and the external environment. This maintains the sealed nature of the tank for leakage prevention while enabling pressure equalization to ensure smooth liquid flow to the vaporization assembly.
Solution Approach 2:
The seal member provides localized sealing at specific interfaces (between the e-liquid storage tank and housing, and between the vaporization assembly and housing) while the communication channel remains open for pressure equalization. This local differentiation of sealed and open regions resolves the contradiction between containment and pressure balance.
3Reliability
If a seal member is added to prevent e-liquid leakage, then liquid containment is improved, but the structure becomes more complex
Solution Approach 1:
A flexible seal member is used to create effective sealing between the e-liquid storage tank and the housing, and between the vaporization assembly and the housing. The flexible nature of the seal member allows it to conform to the interfaces, providing reliable leakage prevention while maintaining a relatively simple overall structure compared to rigid sealing mechanisms.
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 solution ensures air pressure balance and smooth e-liquid supply, preventing leakage and enhancing user experience by allowing external air to enter the e-liquid storage tank, thus maintaining efficient vaporization.
Implementation Method 1
The seal portion opening and closing the vent channel to allow the external air to enter the e-liquid storage tank
Implementation Method 2
a porous body and a heating body, the porous body including a liquid absorbing surface and a vaporization surface
Implementation Method 3
In a process of performing vaporization processing on the e-liquid, the e-liquid needs to be able to flow to an area in which a vaporization device is located
