Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disposable electronic cigarettes have a limited tobacco liquid capacity and lack the ability to add additional liquid, leading to a short usage time.
Innovation Solution
An electronic cigarette assembly with a liquid bottle that can be installed on the electronic cigarette body, featuring a movable member that rotates to open liquid outlet holes for adding tobacco liquid to the first liquid storage cavity when attached, utilizing a joint structure with fixing slots and convex blocks for secure rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a disposable electronic cigarette uses only one liquid storage cavity with fixed capacity, then the device structure is simple, but the tobacco liquid capacity is limited and usage time is short
Solution Approach 1:
The liquid storage system is segmented into two independent parts: a first liquid storage cavity integrated into the electronic cigarette body and a separate liquid bottle with a second liquid storage cavity. This segmentation allows the tobacco liquid capacity to be increased by adding the liquid bottle without significantly complicating the overall device structure, as the two components can be used independently or combined.
Solution Approach 2:
The liquid bottle is designed to be installable on the electronic cigarette body, with the second liquid storage cavity nested alongside or adjacent to the first liquid storage cavity. The movable member extends from the liquid bottle toward the electronic cigarette body, creating a compact nested arrangement that maximizes liquid capacity while minimizing space occupation and structural complexity.
2Duration of action of moving object
If the liquid bottle is installed on the electronic cigarette body with rotatable movable member, then the tobacco liquid can be added to extend usage time, but the device structure becomes more complex
Solution Approach 1:
The movable member is designed to be rotatable relative to the liquid bottle, transitioning between a first position where it blocks the liquid outlet hole and a second position where it allows liquid flow. This dynamic mechanism enables controlled liquid transfer from the liquid bottle to the first liquid storage cavity, extending usage time while maintaining a relatively simple structural design through straightforward rotational motion.
Solution Approach 2:
The system enables self-service liquid refilling by utilizing the user's own actions (rotating the movable member) to transfer liquid from the external bottle to the internal storage cavity. The movable member automatically blocks or opens the liquid outlet hole based on its rotational position, eliminating the need for complex automated pumping or valve mechanisms.
3Adaptability or versatility
If a movable member is used to control liquid flow from the liquid bottle, then the liquid can be added to the first liquid storage cavity, but the device complexity increases
Solution Approach 1:
The movable member serves multiple functions: it acts as a valve to control liquid flow, a structural connector between the liquid bottle and electronic cigarette body, and a user interface element for initiating liquid transfer. This multi-functionality reduces the need for separate components for each function, thereby increasing adaptability while minimizing the increase in device complexity.
Solution Approach 2:
The movable member acts as an intermediary element between the liquid bottle and the electronic cigarette body's liquid storage cavity. It mediates the liquid transfer process by controllably opening or closing the liquid outlet hole, enabling flexible liquid addition capability while maintaining a simple and unified structural design through this single intermediary component.

AI summary
An electronic cigarette assembly includes an electronic cigarette body (200) and a liquid bottle (100) installed on the electronic cigarette body. The electronic cigarette body is provided with a first liquid storage cavity (2231). The first liquid storage cavity is internally provided with first liquid absorbing cotton (225) for storing tobacco liquid. The electronic cigarette body is provided with first liquid inlet holes (227) communicated with the first liquid storage cavity. The liquid bottle is provided with a second liquid storage cavity (190) for storing tobacco liquid. First liquid outlet holes (131) communicated with the second liquid storage cavity are defined in the liquid bottle. A movable member (140) is rotatably arranged on the liquid bottle. When the liquid bottle is not assembled with the electronic cigarette body, the movable member covers the first liquid outlet holes to prevent the tobacco liquid from flowing out of the first liquid outlet holes.
