Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic cigarette clearomizers lack efficient and user-friendly refill mechanisms, leading to difficulties in determining juice levels and preventing damage from dry wicks, which can affect performance and user experience.
Innovation Solution
A refillable eCig clearomizer design featuring a rotatable mouthpiece and tank with aligned fill and vent apertures, allowing visual juice level indication and preventing juice flow when not refilling, along with a pressure release valve to maintain optimal performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the clearomizer uses a fixed seal between tank and mouthpiece, then structural simplicity is maintained, but refilling access and juice level monitoring become difficult
Solution Approach 1:
The mouthpiece is designed to rotate relative to the tank body around a common longitudinal axis, transforming the static sealed connection into a dynamic joint. This rotational capability allows the mouthpiece to move between a sealed operational position and an open refilling position, providing easy access to the juice reservoir while maintaining structural simplicity when sealed.
Solution Approach 2:
The clearomizer is divided into separable components - the tank body and the mouthpiece - that can rotate relative to each other. This segmentation allows independent access to the juice reservoir for refilling without disassembling the entire device, improving ease of operation while maintaining a relatively simple overall structure.
2Reliability
If the clearomizer prevents juice flow during non-refilling, then leakage is prevented, but refilling operation becomes more complex
Solution Approach 1:
The seal between tank and mouthpiece is dynamic rather than static - it maintains sealing during normal operation but automatically opens during refilling. The rotational movement of the mouthpiece breaks the seal to allow refilling, then re-establishes it when returned to position, preventing leakage without complex control mechanisms.
Solution Approach 2:
The rotatable joint mechanism automatically manages the sealing function - the seal engages or disengages based purely on the rotational position of the mouthpiece relative to the tank, without requiring active control systems. The structure itself provides the leakage prevention functionality.
3Ease of manufacture
If the clearomizer uses a simple fill aperture design, then manufacturing is easier, but visual juice level indication and pressure management become problematic
Solution Approach 1:
The rotatable mouthpiece joint serves multiple functions simultaneously: it provides the sealing connection, enables refilling access, and creates the visual indication mechanism. As the mouthpiece rotates, users can visually monitor juice levels through the joint structure, eliminating the need for separate indication components and maintaining manufacturing simplicity.
Solution Approach 2:
The clearomizer utilizes visual cues through transparency and color changes in the tank material to indicate juice levels. The rotatable joint design incorporates transparent or translucent sections that allow users to observe the juice level visually as the mouthpiece rotates, providing measurement capability without complex sensors or indicators.
4Reliability
If the clearomizer allows continuous juice flow to heater, then atomization performance is maintained, but risk of dry wick damage increases
Solution Approach 1:
The rotatable joint mechanism provides a physical feedback system that monitors juice levels. When juice becomes low, the visual indication through the rotating joint alerts the user to refill, preventing the wick from running dry. This passive feedback mechanism maintains reliable atomization by ensuring continuous juice supply without requiring active sensors.
Solution Approach 2:
The visual indication system allows users to detect low juice levels before the wick actually dries out. By providing advance warning through the rotatable joint's visual cues, users can refill proactively, preventing dry wick damage while maintaining continuous atomization performance during normal operation.

Function Achieved in This Case
Facilitates easy refilling, prevents damage from dry wicks, and maintains consistent performance by allowing visual juice level monitoring and alleviating pressure issues during filling.
Implementation Method 1
The refillable tank is designed to contain eCig juice, which is drawn from the refillable tank to the heater coil by capillary action
Implementation Method 2
the heater coil atomizes the eCig juice in response to a current draw across the heater coil
