Electronic Cigarette Slideable Mouthpiece Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic cigarette designs lack effective protection for the mouthpiece and efficient communication of user information, particularly in terms of battery status and operational state, which affects usability and battery life.
Innovation Solution
The design incorporates a slideable panel system with guide members and connectors allowing movement in both longitudinal and transverse directions, along with a lighting system that adjusts visibility based on the panel's position to conserve battery life and provide user information only when necessary, including the use of RGB LEDs and light diffusers for display purposes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the mouthpiece is always exposed for easy access, then ease of operation is improved, but protection from dirt and debris deteriorates
Solution Approach 1:
The mouthpiece cover is designed to be dynamically movable between extended and retracted positions, allowing the user to switch between protected and accessible states as needed. This dynamic design enables the cover to adapt to different operational requirements - providing protection when not in use and enabling access when required.
Solution Approach 2:
The mouthpiece cover is divided into separate functional components: the cover itself, the guide members for longitudinal movement, and the connectors for transverse movement. This segmentation allows each component to be optimized independently - the cover provides protection, while the guide and connector systems enable controlled movement without compromising either protection or accessibility.
2Loss of information
If the lighting system is always on to display user information, then information communication is improved, but battery life deteriorates
Solution Approach 1:
The lighting system operates periodically rather than continuously - it activates only when the mouthpiece cover is in the retracted position (indicating the device is ready for use) and deactivates when the cover is extended. This periodic operation ensures user information is communicated at appropriate moments while conserving battery life during non-operational states.
Solution Approach 2:
The lighting system's operational state is dynamically linked to the mouthpiece cover position. The light emitter activates or deactivates automatically based on whether the cover is retracted or extended, creating a dynamic information display that responds to the device's operational state rather than providing continuous illumination.
3Adaptability or versatility
If the panel allows movement in both longitudinal and transverse directions, then adaptability is improved, but device complexity deteriorates
Solution Approach 1:
The movement control system is segmented into two independent functional elements: guide members that constrain and guide longitudinal movement along the device body, and connectors that enable transverse movement perpendicular to the longitudinal axis. This segmentation allows each element to handle one degree of freedom, simplifying the overall mechanism while achieving two-dimensional movement capability.
Solution Approach 2:
The connector acts as an intermediary element between the panel and the guide members. It receives the panel and allows transverse movement while the guide members handle longitudinal guidance. This intermediary approach decouples the two movement directions, making the system more adaptable to different positions while keeping individual components simpler.

AI summary
An electronic cigarette device includes an elongate main body including a power supply unit, electrical circuitry and a seating for a liquid reservoir. Front and back panels are slidably attached to the elongate main body and configured to move in the longitudinal direction between an extended position and a retracted position. The panels include connectors configured to slide on rail members in a longitudinal direction. The connectors include a movable portion that is movable relative to a fixed portion, and which allows movement of the panel in a direction that is transverse to the longitudinal axis of the rail members.
