Dual Sprayer With Rotatable Cylinder For Selective Multi-Fluid Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sprayers are limited in their ability to selectively discharge multiple fluids or chemicals from a single bottle, lacking the flexibility to operate with different fluids or chemicals in various applications such as automotive, industrial, and consumer products, which require the simultaneous use of multiple substances.
Innovation Solution
A dual-chamber sprayer with a rotatable cylinder and multiple suction and discharge tubes, allowing for selective alignment with a central passage to enable the independent discharge of two or more fluids, along with a working fluid, through different operational modes, and a secure attachment mechanism to a dual-chamber bottle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single sprayer is used to discharge multiple fluids, then the device complexity increases, but the versatility and adaptability improve
Solution Approach 1:
The sprayer is divided into multiple independent discharge tubes (first discharge tube, second discharge tube) with separate suction tubes for each fluid chamber. This segmentation allows each tube to handle a specific fluid independently, enabling multi-fluid discharge capability while maintaining manageable structural complexity through modular organization.
Solution Approach 2:
The sprayer housing and cylinder are designed to accommodate multiple discharge tubes and suction tubes within a single structure. The rotatable cylinder can align different discharge tubes with the central passage, allowing one sprayer unit to perform multiple functions (discharging different fluids) without requiring separate sprayer devices for each fluid type.
2Adaptability or versatility
If multiple discharge tubes are added to the sprayer, then the ability to discharge multiple fluids improves, but the manufacturing complexity increases
Solution Approach 1:
Each discharge tube is paired with its own dedicated suction tube, creating modular units that can be manufactured independently and then assembled into the sprayer. This segmentation simplifies the manufacturing process by allowing standardized production of individual tube assemblies rather than customizing the entire sprayer for each fluid configuration.
Solution Approach 2:
The suction tubes are positioned within the housing and extend into the bottle, with discharge tubes arranged concentrically or adjacently. The rotatable cylinder containing multiple discharge tubes is nested within the housing, allowing compact arrangement of multiple components within the sprayer body, which simplifies assembly by reducing the number of separate mounting operations required.
3Ease of operation
If a rotatable cylinder with multiple discharge tubes is used, then the operational flexibility improves, but the device complexity increases
Solution Approach 1:
The cylinder is made rotatable within the housing, allowing dynamic reconfiguration of which discharge tube aligns with the central passage. This dynamic capability enables the operator to selectively discharge different fluids by simply rotating the cylinder to the desired position, providing operational flexibility without requiring complex valve mechanisms or multiple separate sprayer units.
Solution Approach 2:
The rotatable cylinder serves as a universal selection mechanism that can position any of the multiple discharge tubes in the active position. This single rotating component replaces the need for multiple separate control mechanisms, simplifying the overall device while maintaining the ability to selectively discharge multiple fluids through one integrated control element.

AI summary
The sprayer includes a housing defining a chamber, and a cylinder within the chamber. The cylinder defines more than one discharge tube positioned in a longitudinal direction within the housing, the cylinder being selectively rotatable within the chamber. More than one suction tube extends from a lower portion of the housing. The more than one suction tube is in selective fluid communication with the more than one discharge tube of the cylinder, as the cylinder is rotated within the chamber.
