Aerosol Device Closure with Rigid Biasing Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol generation devices for heating tobacco or other materials lack user-friendliness, particularly in the design of the closure mechanism, which can be awkward to use and lacks effective control over the movement of the lid, leading to undesirable user experience.
Innovation Solution
An aerosol generation device featuring a closure mechanism with a rigid element and a resilient element, where the resilient element is mounted on the rigid element to provide a biased force, allowing smooth movement between closed and open positions, and optionally includes a guide for the carriage to interact with the closure, ensuring stability and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple lid is used without a control mechanism, then the device complexity is reduced, but the ease of operation deteriorates due to lack of effective control over lid movement
Solution Approach 1:
The closure mechanism transitions from a static simple lid to a dynamic system with controlled movement. The resilient element provides elastic force that enables the lid to move between closed and open positions with user input, while the guide mechanism ensures controlled motion paths, resolving the contradiction between simplicity and ease of operation
Solution Approach 2:
A resilient element (spring) is introduced as an intermediary between the lid and the user's manual input. This spring-based mechanism translates small user movements into effective lid opening/closing actions, providing the necessary control without requiring a complex actuation system
2Ease of operation
If a resilient element is added to provide biasing force, then the ease of operation is improved through smooth movement, but the device complexity increases
Solution Approach 1:
The resilient element introduces dynamic elastic forces that smooth the lid movement. The spring provides continuous biasing force that guides the lid through its movement path, creating smooth operation with minimal user effort while maintaining a relatively simple overall structure
Solution Approach 2:
The resilient element is configured to automatically return the lid to its closed position after opening, providing self-service functionality. This eliminates the need for additional actuators or complex return-mechanisms, improving ease of operation without significantly increasing device complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances the robustness and user-friendliness of the closure mechanism by providing a stable and smooth operation, allowing the device to be easily opened and closed, and optionally includes an activation position for initiating the heating process, improving the overall user experience.
Implementation Method 1
a resilient element mounted on the rigid element, the resilient element being arranged to provide a resilient force that biases the closure towards at least one of the closed position and the open position

AI summary
An aerosol generation device has a body, a closure, a resilient element and a rigid element. The body has an aperture through which an aerosol substrate is receivable into the aerosol generation device. The closure is moveable relative to the aperture between a closed position in which the closure covers the aperture and an open position in which the aperture is substantially unobstructed by the closure. The rigid element has a first end arranged to cooperate with the closure and a second end pivotally coupled to the body such that the rigid element rotates relative to the body as the closure moves between the closed position and the open position. The resilient element is mounted on the rigid element and is arranged to provide a resilient force that biases the closure towards at least one of the closed position and the open position.
