Multi-Compartment Sprayer With Rotary Selection And Nozzle Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-compartment sprayers lack a convenient mechanism for users to selectively choose and ensure unobstructed spraying of products from multiple compartments.
Innovation Solution
A rotary movement assembly with a product selection wheel and unlocking mechanism allows users to select and change products, ensuring unobstructed spraying through a locking system that maintains nozzle alignment and uses a metering system with a piston for controlled dispensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a multi-compartment sprayer allows independent spraying of each fluid, then product versatility is improved, but device complexity increases
Solution Approach 1:
The sprayer is divided into multiple compartments, each housing a separate product container with its own metering system and nozzle. This segmentation allows independent selection and spraying of different products without requiring a complex mixing mechanism, resolving the contradiction between versatility and complexity.
Solution Approach 2:
The sprayer employs a universal trigger mechanism and common nozzle assembly that can dispense any of the multiple products stored in different compartments. This multi-functionality allows a single device structure to handle multiple products, improving versatility while controlling overall device complexity.
2Ease of operation
If a rotary movement assembly is added for product selection, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The rotary movement assembly is merged with the existing distributor drum structure. The product selection wheel integrates with the drum's rotational mechanism, allowing product selection to be performed through the same rotational motion used for dispensing. This combination improves ease of operation while minimizing the addition of separate complex components.
3Productivity
If the nozzle is positioned to ensure unobstructed spraying, then spray performance is improved, but accessibility for product change is reduced
Solution Approach 1:
The sprayer incorporates a movable body that can be unlocked and displaced axially to expose the product selection wheel. This dynamic positioning allows the nozzle to remain in its optimal fixed position for unobstructed spraying during use, while enabling easy access to the product selection mechanism when product changes are needed, thus resolving the contradiction between spray performance and accessibility.
4Reliability
If a locking mechanism is implemented to maintain nozzle alignment, then reliability is improved, but ease of operation is reduced
Solution Approach 1:
The locking mechanism is designed to automatically engage and disengage based on the position of the movable body. When the movable body is in the retracted position, the locking mechanism automatically secures the nozzle alignment. When the movable body is displaced for product selection, the locking mechanism automatically releases. This self-service behavior maintains reliability without requiring manual operation of the locking mechanism, thus preserving ease of operation.

AI summary
A multi-compartment sprayer with a main body and an outer casing and which houses a plurality of conduits intended for containing fluids to be sprayed independently. It includes movable equipment having a rotary movement assembly which rotates about a guide shaft of the sprayer and allows selecting the product to be sprayed and has an unlocking movement assembly configured to move axially in the direction of the guide shaft. Likewise, the sprayer includes fixed equipment with a fixed casing inside which the movement assemblies are arranged and with an actuating trigger and a locking button to allow/prevent the change of nozzles for product selection.
