Monoblock Fluid Dispenser with Integrated Suction and Spray
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid dispenser devices are unable to function in both suction and expulsion modes, and they often require multiple parts for assembly, which complicates their manufacturing and usage, preventing reproducible and correct spraying.
Innovation Solution
A fluid dispenser unit with a single-piece extractor head integrated with the reservoir, capable of suction and expulsion, and a spray head that can be assembled for spraying, featuring dose-fractioning and energy accumulation means to manage fluid dispensing in multiple doses, and a non-airtight connection to manage pressure during mixing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a spray head is assembled from two or more parts, then the spray profile can be defined, but the device complexity increases and manufacturing becomes more complicated
Solution Approach 1:
The patent integrates the spray head components into a single monoblock structure where the body and nozzle are formed as one piece. This eliminates the need for separate assembly of multiple parts while maintaining the spray profile definition capability through integrated non-radial channels formed directly in the monoblock structure.
2Object-generated harmful factors
If a spray head is assembled on a syringe, then fluid can be sprayed, but the suction mode functionality is lost
Solution Approach 1:
The monoblock spray head design allows the syringe to perform both suction and spray functions. The integrated structure enables the syringe plunger to directly engage with the spray head, allowing the user to first suction fluid into the syringe reservoir and then spray it out through the same device, eliminating the need for separate suction and spray devices.
3Object-generated harmful factors
If multiple parts are assembled together, then the spray function is achieved, but the assembly and manufacturing process becomes more time-consuming and costly
Solution Approach 1:
By forming the spray head as a single monoblock component, the manufacturing process is simplified to a single molding or machining operation rather than multiple assembly steps. This significantly reduces manufacturing time and cost while maintaining the spray function, as the monoblock structure can be produced efficiently through modern manufacturing techniques.

AI summary
A method of using a fluid dispenser unit having a reservoir and a piston that slides in the reservoir. The unit includes an extractor head secured to the reservoir to suck fluid to be dispensed into the reservoir, and a spray head assembled on the extractor head to spray the fluid out from the reservoir. The method includes the steps of sucking a fluid to be dispensed into the reservoir through the extractor head; assembling the spray head on the extractor head; and spraying the fluid through the spray head. The step of sucking up a fluid to be dispensed includes a first step of extracting a fluid, such as a solvent, from an extraction reservoir, and a second step of mixing the fluid with a first substance, such as a powder or a lyophilisate, so as to form the fluid to be dispensed.
