Electronic Cigarette Battery Assembly Impact Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic cigarette housings are prone to damage from impact when dropped due to the susceptibility of the rear cover to direct contact with the ground, leading to potential cracks and damage to internal components.
Innovation Solution
A battery assembly design featuring a main body with an extension that covers the rear cover, providing protection by wrapping it during a drop, and utilizing buckles and limiting structures to secure the rear cover to the main body, shifting the center of gravity and distributing impact force effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the rear cover is made susceptible to impact contact during drops, then the electronic cigarette structure remains simple and lightweight, but the rear cover and internal components are damaged
Solution Approach 1:
The main body extends in the longitudinal dimension to cover the rear cover, creating a protective extension that changes the spatial arrangement from a simple two-part structure to an integrated three-dimensional protective structure. This extension wraps around the rear cover to provide impact protection without requiring additional separate protective components.
Solution Approach 2:
The protective function is merged into the main body structure itself through the extension, rather than being a separate component. The main body simultaneously serves as the housing structure and the protective element, combining structural support and impact protection functions into a single integrated component.
2Stability of the object's composition
If the rear cover is securely fixed to the main body, then the rear cover stability during drops is improved, but the manufacturing complexity increases due to multiple connecting structures
Solution Approach 1:
The connection system is segmented into multiple independent fastening mechanisms: connecting buckles for primary attachment, connecting female buckles with connecting sub-buckles for secondary securing, and fixing buckles for final stabilization. This segmentation allows each component to perform a specific fastening function, making the assembly process systematic and manageable despite the multiple connection points.
Solution Approach 2:
The connecting buckles, connecting female buckles, and fixing buckles serve as intermediary elements between the main body and rear cover. These intermediary components facilitate the connection process by providing standardized attachment points and mechanical engagement features that simplify the assembly of the two main structural components.

AI summary
A battery assembly and an electronic cigarette using the battery assembly are provided. The battery assembly comprises a main body and a rear cover fixedly installed to the main body. One end of the main body is provided with a connecting portion fixedly electrically connected to an external load, and the other end thereof is provided with an inner cavity for accommodating an electronic component. The rear cover is fixedly installed to the main body and covers the inner cavity. One end of the main body far from the connecting portion is provided with an extension toward the rear cover, and the extension covers the end of the rear cover far from the connecting portion, effectively preventing the phenomenon that a housing far from the end of a suction port is damaged by impact when the electronic cigarette is dropped.
