Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electronic cigarette designs with threaded connections are inconvenient, costly, and have a short service life due to metal friction, leading to metal scraps and mechanical wear.
Innovation Solution
A pluggable connection system using elastic snap or detachable clip mechanisms between the atomizer and battery pack, eliminating the need for threaded connections, which includes elastic engaging members and non-rotational joints for secure and reliable electrical contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If threaded connection is used between atomizer and battery rod, then structural connection and circuit connection are achieved, but operation becomes inconvenient and troublesome
Solution Approach 1:
The connection structure is divided into separate functional elements: a connection piece with circuit board, connecting piece with elastic engaging member, and battery rod with corresponding interfaces. This segmentation allows for simplified assembly where the atomizer connects to the battery rod through a straightforward insertion motion rather than complex threading operations.
Solution Approach 2:
The traditional mechanical threaded connection system is replaced with an elastic engaging member system. The connecting piece uses an elastic engaging member that automatically engages with the connection piece through elastic deformation, eliminating the need for manual threading and rotation operations.
2Ease of manufacture
If threaded connection with mechanical processed hardware parts is used, then connection is achieved, but cost becomes relatively high
Solution Approach 1:
The connection mechanism changes from rigid threaded parameters to elastic deformation parameters. The elastic engaging member utilizes elastic modulus and deformation characteristics to achieve connection, allowing for simpler manufacturing processes and lower costs while maintaining reliable electrical and mechanical connection through the elastic engagement.
3Duration of action of moving object
If connection part is rotated during usage, then connection is maintained, but friction between metals generates metal scraps and shortens service life
Solution Approach 1:
The rotating mechanical threaded connection is replaced with a static elastic engagement system. The elastic engaging member maintains connection through elastic force without requiring rotation, thereby eliminating metal-on-metal friction that generates harmful metal scraps and extends the service life of the connection components.
Solution Approach 2:
The potential harm of metal friction is converted into benefit by using elastic material engagement instead of metal threading. The elastic engaging member provides the necessary mechanical force without the harmful friction effects, transforming the connection mechanism to avoid the harmful factor entirely.
