Solution Overview
Problem
Existing vaporizing devices suffer from issues such as uneven pressure distribution causing oil leakage, intricate mold degradation, and structural failures in locking sleeves, leading to frequent cartridge replacement and unsightly stains.
Innovation Solution
A locking structure with a circular body and a single inwardly extending clamp, featuring a notch and angled wall, provides a secure one-way press-fit connection that ensures even pressure distribution and reduces mold complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If clamp spring bars with teeth-like projections are used to secure the mouthpiece, then the mouthpiece can be attached to the cartridge, but uneven pressure distribution causes oil leakage
Solution Approach 1:
The clamp is divided into multiple independent clamp spring bars with teeth-like projections. Each clamp spring bar independently engages with the air guide tube, distributing the attachment force across multiple contact points. This segmentation prevents concentration of pressure at a single point, thereby preventing oil leakage while maintaining secure mouthpiece attachment.
Solution Approach 2:
The clamp spring bars are designed with specific local characteristics including chamfered edges and hooked portions that engage the air guide tube. The chamfered edges provide controlled engagement angles, while the hooked portions ensure positive locking. This local quality optimization ensures even pressure distribution across the engagement interface, preventing oil leakage.
2Reliability
If clamp spring bars with intricate details are formed, then secure engagement is achieved, but mold degradation increases and manufacturing precision decreases
Solution Approach 1:
The clamp is segmented into multiple independent clamp spring bars, each with simpler geometry compared to a single intricate clamp. This segmentation allows each component to be molded with fewer fine details, reducing mold degradation while maintaining overall locking reliability through the collective action of multiple simpler elements.
Solution Approach 2:
The clamp spring bars are designed as elastic components that can dynamically adjust during assembly. The elastic material properties allow the clamp spring bars to flex and engage the air guide tube with appropriate force, reducing the need for extremely precise mold details while ensuring reliable locking engagement.
3Reliability
If multiple clamp spring bars are used, then secure attachment is achieved, but device complexity increases
Solution Approach 1:
Multiple clamp spring bars are merged into a single integrated clamp assembly that functions as one unit. The clamp spring bars are positioned and oriented to simultaneously engage the air guide tube, creating a unified locking mechanism. This merging approach maintains attachment security while avoiding the complexity of multiple separate components, as the clamp spring bars work together as a single functional element.

AI summary
This disclosure relates generally to vaporizing devices and components of vaporizing devices, such as mouthpiece locking structures. In various aspects, a locking structure for a mouthpiece includes a circular body extending between a proximal end and a distal end, where an interior surface of the body defines a central lumen. The locking structures may also include a clamp disposed within the central lumen, where the clamp has an angled wall extending inwardly from a rim of the interior surface of the body towards the central lumen. The clamp may additionally include a notch within the angled wall, with the angled wall of the clamp (i) encircling a substantial entirety of a circumference of the body, (ii) defining a clamp lumen, (iii) having a thickness ranging from about 0.5 mm to about 0.7 mm, and (iv) having an angle or bias of from about 100° to about 110°.
