Removable Brass Aerosol Nozzle for Reuse
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing replacement nozzles for aerosol canisters are prone to breakage, often made of plastic, and fail to detach from empty canisters, preventing reuse and lacking control over nozzle height, which hinders effective aerosol ejection.
Innovation Solution
A replacement nozzle design featuring a body, flange, and attachment sections with a thread for secure attachment to the aerosol canister stem, allowing controlled aerosol expulsion and removable attachment, potentially fabricated from brass with specific thread characteristics for enhanced durability and usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the replacement nozzle is made of plastic to reduce cost, then manufacturing cost is reduced, but the nozzle becomes susceptible to breakage
Solution Approach 1:
The replacement nozzle is made from brass, a metal material, instead of plastic. This material substitution provides superior strength and breakage resistance while maintaining manufacturability through processes like CNC machining or injection molding of metal components.
2Reliability
If the replacement nozzle is permanently attached to the canister, then attachment security is improved, but the nozzle cannot be removed when the canister is empty, preventing reuse
Solution Approach 1:
The attachment mechanism transitions from a permanent fixed connection to a dynamic removable connection. The nozzle is attached to the canister stem via a threaded interface that provides secure attachment during use but allows for easy removal when the canister is empty, enabling the nozzle to be reused with a new canister.
3Device complexity
If the replacement nozzle height is fixed, then manufacturing complexity is reduced, but the nozzle cannot be adjusted to control aerosol ejection effectiveness
Solution Approach 1:
The nozzle height is made adjustable rather than fixed. The nozzle can be positioned at different heights relative to the canister opening, allowing users to optimize aerosol ejection performance for different applications. This is achieved through a removable attachment design that allows height adjustment while maintaining secure connection during operation.

AI summary
A replacement nozzle for an aerosol canister including a body section including a body channel and an exit aperture in fluidic communication with the body channel, a flange section including a flange channel positioned in fluidic communication with the body channel, and an attachment section including an attachment channel positioned in fluidic communication with the flange channel, an entry aperture positioned in fluidic communication with the attachment channel, and a thread positioned on an outer surface of the attachment section operable to removably attach the replacement nozzle to a stem of an aerosol canister. The attachment of the replacement nozzle enables depression of the stem of the aerosol canister resulting in expulsion of an aerosol comprised by the aerosol canister into the replacement nozzle through the entry aperture, through the attachment channel, through the flange channel, through the body channel, and exit from the replacement nozzle through the exit aperture.
