Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the atomizer core remains stationary and connected to the liquid storage tank, then the structure is simple and easy to manufacture, but e-liquid leaks during storage and flavor deteriorates
Solution Approach 1:
The atomizer core is designed to move vertically relative to the liquid storage tank. During storage, the atomizer core moves to a position where the liquid inlet hole is sealed by the liquid inlet hole sealing ring, isolating the e-liquid from air. During use, the atomizer core moves to allow liquid flow. This dynamic positioning resolves the contradiction by providing reliable sealing without requiring complex additional sealing structures.
Solution Approach 2:
The sealing function is segmented into dedicated sealing rings (liquid inlet hole sealing ring and air inlet hole sealing ring) that are positioned at specific locations. This segmentation allows the sealing mechanism to be simple and reliable, with each sealing ring responsible for a specific function, avoiding the need for complex integrated sealing structures.
2Object-affected harmful factors
If the atomizer core is designed with movable components for liquid-air separation, then e-liquid leakage is prevented, but the device complexity increases
Solution Approach 1:
The atomizer core moves vertically to control the communication between liquid inlet hole and liquid storage cavity. During storage, the liquid inlet hole is sealed; during use, it communicates with the liquid storage cavity. This simple dynamic mechanism effectively prevents e-liquid leakage without requiring complex sealing systems.
Solution Approach 2:
The liquid inlet hole sealing ring acts as an intermediary element that provides sealing between the atomizer core and the liquid storage tank. This simple intermediary component resolves the leakage issue without adding complex sealing mechanisms to the atomizer core itself.
3Productivity
If the liquid inlet hole remains open during storage, then liquid flow is maintained, but e-liquid flavor deteriorates and leakage occurs
Solution Approach 1:
The atomizer core dynamically changes position between storage and use states. During storage, the liquid inlet hole is sealed to maintain e-liquid quality and prevent leakage. During use, the atomizer core moves to allow liquid flow. This dynamic design resolves the contradiction by ensuring both quality stability and flow efficiency at appropriate times.
Solution Approach 2:
The sealing rings are pre-positioned at specific locations on the liquid storage tank. Before the atomizer core moves into the liquid flow position, the sealing rings are already in place to seal the liquid inlet hole. This preliminary positioning ensures that sealing is established before liquid flow begins, preventing leakage and maintaining e-liquid quality.
