Electronic Cigarette Cover Stabilization via Elastic Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic cigarette cases suffer from structural wobble and instability due to the cover not being able to maintain a secure position when detached from the case body, leading to potential noise and user dissatisfaction.
Innovation Solution
A case design incorporating an elastic assembly with a pivot and a torsion spring mechanism that stabilizes the cover by using an elastic element and rod to prevent wobbling, ensuring the cover remains securely positioned and rotates smoothly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cover is detachably mounted to the case body with a pivot, then the cover can be opened and closed, but the cover cannot be retained in a certain position and will wobble easily
Solution Approach 1:
An elastic assembly is introduced as an intermediary component between the cover and case body. The elastic assembly includes an elastic element (spring) that provides continuous positional control of the cover, preventing wobble while maintaining the detachable pivot connection. The elastic element acts as a mediator that exerts restoring force to keep the cover stable at any angular position.
Solution Approach 2:
The elastic assembly changes the mechanical parameters of the cover connection by introducing elastic force. The spring constant and pre-compression of the elastic element are adjusted to provide appropriate restoring force, transforming the rigid pivot connection into a controlled elastic connection that maintains stability.
2Stability of the object's composition
If the cover is held firmly in position, then wobble and noise are prevented, but the opening and closing operation becomes slower
Solution Approach 1:
The elastic assembly provides dynamic control of the cover position rather than static locking. The elastic element continuously adjusts its force based on the cover's position, allowing smooth acceleration during opening/closing while maintaining stability at rest. This dynamic elastic support enables both speed and stability.
3Device complexity
If a simple pivot connection is used, then the structure is simple, but the cover generates noise and wobbles
Solution Approach 1:
The elastic assembly serves as a mediator between the simple pivot connection and the cover, adding minimal structural complexity while effectively eliminating noise and wobble. The elastic element absorbs vibrations and provides continuous positional control without requiring complex locking mechanisms.

AI summary
The present disclosure relates to a case, a battery assembly and an electronic cigarette having the case. The case includes a main body, a cover, and an elastic assembly. The cover is pivotally mounted to the main body. One end of the cover adjacent to the main body defines a groove. The elastic assembly is located at the main body; the elastic assembly has a top portion being in alignment with the groove. The top portion is configured for supporting on a certain portion of the cover when the cover is rotated.
