Aerosol Generator Removable Handle and Blocking Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol generators lack a removable handle and maneuver prevention device that allows for safe and ergonomic operation, particularly for professional use where long or repetitive button presses are necessary, and fails to separate the diffuser and handle while maintaining safety features.
Innovation Solution
Aerosol generator assembly with a diffuser cover and removable handle featuring a protective member for the push button, which includes a base that snaps onto the dome, a rotatable push-button assembly with latching means to prevent valve operation, and a handle with a trigger mechanism and over-cap for actuating the push button, allowing for safe and secure operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a diffuser cover with push button is provided for actuating the valve, then the generator becomes safer and more ergonomic, but it cannot be separated from the handle in professional use where long or repetitive presses are necessary
Solution Approach 1:
The diffuser cover is divided into two separable parts: a base that remains attached to the aerosol generator and a handle assembly that can be attached or removed as needed. The base includes a push button mechanism while the handle assembly includes a trigger mechanism, allowing professional users to attach the handle for extended use while maintaining the safety features of the base.
2Reliability
If a protective member is added to surround the push button, then accidental activation is prevented, but the device complexity increases
Solution Approach 1:
The protective member is merged with the push button assembly to form an integrated unit. The protective member surrounds the push button and is rotatably mounted on the base, combining protection functionality with the actuation mechanism without requiring separate protective structures.
Solution Approach 2:
The protective member is designed to be rotatable relative to the base, transitioning between a locked position that prevents push button actuation and an unlocked position that allows normal operation. This dynamic element provides safety without requiring complex mechanical locking structures.
3Stability of the object's composition
If latching means are provided to hook the protective member on the base, then the protective member remains securely attached, but the manufacturing precision requirements increase
Solution Approach 1:
The latching means are designed to automatically engage when the protective member is rotated into the locked position. The first latching means on the base and the second latching means on the protective member's skirt automatically hook together through the rotation motion, eliminating the need for precise manual alignment during operation.

AI summary
The cover (4) has a protection element (10) and a base plate (8) including locking units adapted to cooperate to hold the protection element on the base plate. One of the locking units is formed on the base plate and carried by an inner wall and an outer wall of an annular groove. The other locking unit is formed on an inner surface of an annular skirt of the protection element. The groove of a width is adapted to oppose disengagement of the skirt by pulling. The protection element includes a cap fixed on the base and surrounding a pushbutton (6). The skirt is surrounded by the cap. An independent claim is also included for an aerosol generator.
