Threaded Electronic Cigarette Power Supply Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic cigarettes with buckle or elastic locking structures experience weak connection strength and noise issues, leading to easy separation and damage when dropped, and are prone to water ingress due to gaps between the cover and main body.
Innovation Solution
A power supply design featuring a threaded connection between the cover and main body, with a handle for easy rotation and a sealing member to prevent water ingress, enhancing connection stability and user control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a buckle or elastic locking structure is used to mount the cover to the main body, then the cover can be opened and closed easily, but the connection strength becomes weak and noise is generated during use
Solution Approach 1:
The cover mounting structure is segmented into a threaded connection system comprising threads on the cover body and corresponding threaded holes in the main body, replacing the unified buckle/elastic structure with distributed threaded engagement points that provide superior mechanical strength while maintaining operability
Solution Approach 2:
The mechanical buckle or elastic locking system is replaced with a threaded fastening system that converts the opening/closing action into a rotational threading motion, providing stronger mechanical engagement through screw-thread mechanics rather than simple snap-fit or buckle mechanisms
2Ease of operation
If a gap is provided between the cover and main body to facilitate opening and closing, then the cover can be operated easily, but water can enter the internal chamber through the gap
Solution Approach 1:
A sealing ring is introduced as an intermediary element between the cover body and main body, positioned in a groove on the cover body to create a water-tight barrier that prevents water ingress through the gap while allowing the cover to be opened and closed
Solution Approach 2:
A flexible sealing ring (O-ring or similar elastomeric seal) is used to create a compliant waterproof barrier that can deform during opening/closing operations while maintaining water tightness, preventing water from penetrating through the gap between cover and main body
3Device complexity
If the cover is fixed using a buckle or elastic locking structure, then the assembly is simple, but the connection strength is weak and parts are easily separated when dropped
Solution Approach 1:
The mounting structure is segmented into threaded engagement features distributed around the cover body, providing multiple points of mechanical attachment that collectively resist impact forces and prevent separation, while maintaining a relatively simple overall assembly process
Solution Approach 2:
The threaded connection system utilizes the inherent mechanical advantage of screw threads, which convert small rotational forces into strong axial clamping forces, providing high impact resistance through the geometric curvature and mechanical leverage of the threaded engagement
