Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pressurized aerosol cans face issues such as storage logistics challenges, damage rendering them unusable, and difficulty in recycling due to the need for initial pressurization and sealing, as well as hazards from propellants.
Innovation Solution
A sprayer assembly that connects to a variety of pressurized air sources and uses pre-filled, non-pressurized fluid containers, allowing for easy replacement and recycling, with a sprayer-head assembly that includes a pressure regulator, check valve, and aerosol valve compartment for adjustable pressure and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pre-pressurized aerosol cans are used, then the fluid can be sprayed immediately, but storage logistics become complex and the cans are vulnerable to damage
Solution Approach 1:
The system divides the aerosol generation function into two separate components: a reusable pressurized canister that contains only propellant and pressurized air, and a replaceable non-pressurized fluid container that holds the fluid. This segmentation allows the pressurized component to be robust and reusable while the fluid container can be easily replaced if damaged, resolving the contradiction between immediate spray capability and vulnerability to damage.
Solution Approach 2:
The patent introduces a canister as an intermediary component that provides pressurization without containing the fluid. The canister acts as a mediator between the pressurized air source and the fluid container, enabling the fluid to be aerosolized without the fluid container itself being pressurized and vulnerable to damage.
2Ease of operation
If pre-pressurized cans are used, then spray function is immediate, but recycling becomes difficult due to pressurization and sealing requirements
Solution Approach 1:
By separating the pressurized canister from the fluid container, the system allows the fluid container to be a simple, non-pressurized component that can be easily emptied, cleaned, and refilled. This segmentation eliminates the complex depressurization and sealing procedures required for recycling traditional aerosol cans, making the fluid container highly recyclable while maintaining immediate spray function.
Solution Approach 2:
The patent enables easy recovery and reuse of the fluid container by separating it from the pressurized canister. The fluid container can be discarded, emptied, cleaned, and refilled without affecting the pressurized canister, which remains reusable. This approach dramatically simplifies the recycling process compared to traditional sealed aerosol cans.
3Ease of operation
If conventional aerosol cans are used, then propellants are contained, but hazards arise from propellant storage and potential leakage
Solution Approach 1:
The patent extracts the propellant and pressurized air from the fluid container and places them in a separate canister. This extraction eliminates the hazard of having both flammable propellants and user-replaceable fluid containers combined in one pressurized unit. The propellant is contained in a permanent, properly designed canister while the fluid container remains non-pressurized and free from propellant hazards.
4Productivity
If pressurized containers are used, then spray performance is achieved, but storage logistics become challenging
Solution Approach 1:
The system segments the aerosol system into a permanent pressurized canister for storage and a replaceable fluid container. The pressurized canister can be stored in fixed locations since it contains no fluid, while fluid containers can be stored anywhere in non-pressurized form. This segmentation dramatically simplifies storage logistics while maintaining spray performance when needed.

AI summary
This application describes a sprayer assembly that can attach to a variety of different types of pre-filled, fluid containers (e.g., non-pressurized fluid containers) for holding the fluid to be sprayed. For example, the sprayer assembly can include a sprayer-head assembly for attaching to a container of fluid, a canister for holding the container of fluid, or any combination thereof In addition, the sprayer assembly can be connected to a variety of different types of pressurized air sources. The sprayer-head assembly can include a nozzle assembly (e.g., fluid uptake tube, valve, and nozzle head), as well as a trigger for actuating the nozzle assembly.
