Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the e-liquid bottle is connected to the pumping head assembly by threads, then the connection is secure, but the assembly and disassembly become inconvenient
Solution Approach 1:
The connection structure is divided into separate components: the pumping head assembly with protrusions and the e-liquid bottle with corresponding grooves. This segmentation allows for tool-free assembly and disassembly while maintaining secure connection through the interlocking geometry of the protrusion-groove interface.
Solution Approach 2:
The protrusion-groove interface acts as an intermediary mechanism between the pumping head assembly and e-liquid bottle. This intermediate structure enables both secure connection and easy assembly/disassembly without requiring threading operations, resolving the contradiction between connection reliability and operational convenience.
2Device complexity
If conventional squeezing method is used to pump e-liquid, then the structure is simple, but the e-liquid can't be completely pumped clean
Solution Approach 1:
The manual squeezing mechanism is replaced with a piston-based pumping system. The piston moves within the pumping body to create pressure differential, drawing e-liquid through the suction pipe from the bottle and delivering it to the atomizer. This mechanical substitution enables complete e-liquid extraction while maintaining relatively simple structure.
Solution Approach 2:
The pumping assembly utilizes pneumatic principles where the piston creates pressure changes to move e-liquid through the system. By pressing the piston, air is expelled from the pumping body, creating a pressure differential that draws e-liquid through the suction pipe and pushes it through the feeding tube to the atomizer, achieving complete extraction.
3Productivity
If the piston is pressed to expel air from the pumping body, then e-liquid can enter the pumping body, but the structure becomes more complex
Solution Approach 1:
Multiple functions are merged into the pumping head assembly: the pumping body houses the piston, the e-liquid suction pipe delivers liquid to the pumping chamber, the feeding tube transports liquid to the atomizer, and sealing portions ensure proper sealing. This functional integration achieves efficient e-liquid pumping while controlling overall structural complexity through unified design.

AI summary
An e-liquid pumping assembly for supplying e-liquid to an atomizer includes a housing, an e-liquid bottle, and a pumping head assembly. The pumping head assembly includes a piston, a pumping body clamped with the e-liquid bottle by a first sealing portion, a pumping cover clamped with the pumping body, a feeding tube connected to the atomizer and the pumping body. The piston includes a first lower end inserted into the pumping body and a first upper end exposed from the pumping cover. The e-liquid suction pipe includes a second lower and upper ends respectively inserted into the e-liquid bottle and the pumping body. The piston is pressed to expel air from the pumping body so that e-liquid enters the pumping body through the e-liquid suction pipe. The piston is again pressed for pushing the e-liquid out of die pumping body to the atomizer through the feeding tube.
