Segmented Mouthpiece Structure for Easier Demolding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The mouthpiece structure in aerosol generation devices is difficult to demold during molding due to the arrangement of the step structure and the snap structure.
Innovation Solution
The mouthpiece structure is divided into two structural parts: a mouthpiece body and a connector. The connector is designed to snap with the vent tube, and the mouthpiece body features an air guide hole and a plug hole that communicate with each other, allowing for easy assembly and demolding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mouthpiece structure is designed with both step structure and snap structure integrated, then the connection reliability between vent tube and mouthpiece is improved, but the difficulty of demolding during molding increases
Solution Approach 1:
The mouthpiece structure is divided into two separate components: the mouthpiece body (containing the step structure) and the connector (containing the snap structure). This segmentation allows each component to be molded independently without demolding difficulties, while maintaining reliable connection when assembled together. The connector is inserted into the mouthpiece body to form the complete assembly.
2Stability of the object's composition
If the step structure and snap structure are integrated in one piece, then the structural integrity is improved, but the processing complexity increases
Solution Approach 1:
The structure is segmented into mouthpiece body and connector components, each with simplified geometry that is easy to mold. The mouthpiece body contains the step structure for guiding the connector, while the connector contains the snap structure for connection. This segmentation reduces processing complexity while maintaining structural integrity through precise assembly.
Solution Approach 2:
The connector is nested within the mouthpiece body structure, where the connector fits into the mouthpiece body through the step structure. This nesting arrangement allows both components to be integrated in a compact configuration while keeping each component's geometry simple and moldable.
3Reliability
If the connector is designed to snap with both vent tube and outer cylinder, then the connection reliability is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The mouthpiece body is pre-formed with the step structure that guides the connector into proper position during assembly. The step structure acts as a preliminary positioning feature that ensures the connector aligns correctly with both the vent tube and outer cylinder before the snap connection is formed, reducing the precision requirements for the final snap fit.

AI summary
A mouthpiece structure includes: a mouthpiece body having an outer cylinder and an inner cylinder extending from a top end of the outer cylinder into an inner cavity of the outer cylinder; and a connector arranged in the inner cavity of the outer cylinder, the connector and the inner cylinder being arranged in an axial direction of the outer cylinder, the connector being sleeved outside a vent tube. The inner cylinder has an air guide hole and a plug hole that are in communication with each other, the plug hole being plug-fitted with a top end of the vent tube. The air guide hole docks with a top end of the vent tube to guide an airflow out of the vent tube. The connector is configured to snap with the vent tube. The connector is snapped with the outer cylinder.
