Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing atomizing systems face limitations in delivering large amounts of atomized fluid quickly and accurately, particularly in emergency situations, and pose challenges regarding sterility and correct assembly due to separate parts that need to be connected.
Innovation Solution
An atomizing system comprising a syringe barrel with graduated markings and a fixedly attached atomizer, allowing for continuous and controlled dispensing of fluid through a plunger movement, with the atomizer welded to the syringe tip to prevent separation and ensure sterility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a spray head is integrally formed with the atomizer (first group), then the device structure is simple and easy to manufacture, but the amount of fluid atomized is limited by single spray strokes and cannot deliver large amounts quickly
Solution Approach 1:
The patent combines the advantages of both atomizing systems by integrating the atomizer with a syringe barrel, merging the simple structure of pump dispensers with the continuous delivery capability of syringes. This allows for both easy manufacture and continuous atomization of large fluid amounts.
Solution Approach 2:
The invention introduces a dynamic plunger mechanism within the syringe barrel that can be moved continuously or in controlled strokes, enabling flexible adjustment of fluid delivery rate from slow continuous flow to rapid bulk delivery, thus resolving the productivity limitation.
2Productivity
If a syringe with luer slip is used (second group), then continuous application of large amounts of atomized fluid is possible, but the spray head must be plugged onto the luer slip prior to use which increases complexity and sterility risks
Solution Approach 1:
The atomizer is directly integrated into the syringe tip, eliminating the need for separate spray head components and plugging operations. This merging of components maintains continuous fluid delivery capability while reducing device complexity and assembly steps.
Solution Approach 2:
The invention segments the atomizing system into a self-contained unit where the atomizer, syringe barrel, and tip form an integrated assembly, allowing the fluid pathway to be continuously open without requiring connection of separate parts.
3Adaptability or versatility
If separate parts are used that must be plugged together, then adaptability is improved, but sterility is compromised and risk of incorrect assembly increases
Solution Approach 1:
By merging the atomizer and syringe into a single integrated unit with a self-contained fluid pathway, the invention eliminates multiple connection points where sterility could be compromised or incorrect assembly could occur, while maintaining design flexibility.
4Ease of manufacture
If the atomizer is not fixedly attached to the syringe tip, then ease of manufacture is improved, but the spray head may get loose during transportation and active ingredients may be spilled
Solution Approach 1:
The atomizer is pre-fixed to the syringe tip during manufacturing through appropriate attachment methods, ensuring connection stability is established before the product enters circulation, thereby preventing loosening during transportation while maintaining manufacturing efficiency.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case

Implementation Method 1
a pressure is applied to at least a portion of the stored fluid, which is thereby urged through an atomizer
Implementation Method 2
urged through an atomizer, e.g. a nozzle, which atomizes the fluid
Implementation Method 3
the spray head is pushed back to its initial position by an elastic element
Implementation Method 4
a plunger of the syringe may be moved within a single stroke until a specific amount of atomized fluid is applied
Implementation Method 5
the atomizer welded to the syringe tip to prevent separation and ensure sterility

AI summary
The present invention relates to an atomizing means 1, particularly for a nasal spray. The atomizing means comprises a syringe barrel 2 and an atomizer 3. The syringe barrel 2 comprises a first opening 4 and a second opening 5, wherein a first inner volume 15 is defined between the first opening 4 and the second opening 5. Thereby, the first opening 4 is configured for receiving a plunger 6. Further, the syringe barrel 2 comprises a syringe tip 7. The syringe tip 7 comprises a fluid inlet 8 and a fluid outlet 9, wherein a second inner volume 16 is defined between the fluid inlet 8 and the fluid outlet 9. The fluid inlet 8 is in communication with the second opening 5 of the syringe barrel 2. Moreover, the atomizer 3 is fixedly attached to the fluid outlet 9.
