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

VSEngineering 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

Engineering Contradiction:
Improverefilling accessVSAvoidstructural complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

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.

Inventive Principle:
Principle #15Dynamics

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.

Inventive Principle:
Principle #1Segmentation

2Reliability

If the clearomizer prevents juice flow during non-refilling, then leakage is prevented, but refilling operation becomes more complex

Engineering Contradiction:
Improveleakage preventionVSAvoidrefilling operation
Core Design Contradiction:
ReliabilityVSEase of operation

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.

Inventive Principle:
Principle #15Dynamics

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.

Inventive Principle:
Principle #25Self-service

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

Engineering Contradiction:
Improvefill aperture designVSAvoidjuice level indication
Core Design Contradiction:
Ease of manufactureVSDifficulty of detecting and measuring

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

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.

Inventive Principle:
Principle #32Color changes

4Reliability

If the clearomizer allows continuous juice flow to heater, then atomization performance is maintained, but risk of dry wick damage increases

Engineering Contradiction:
Improveatomization performanceVSAvoiddry wick damage
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

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.

Inventive Principle:
Principle #23Feedback

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.

Inventive Principle:
Principle #10Preliminary action
