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

VSEngineering 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

Engineering Contradiction:
Improveintegral formation of spray head and atomizerVSAvoidamount of fluid atomized per unit time
Core Design Contradiction:
Ease of manufactureVSProductivity

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.

Inventive Principle:
Principle #5Merging (Combining)

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.

Inventive Principle:
Principle #15Dynamics

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

Engineering Contradiction:
Improvecontinuous application of atomized fluidVSAvoidseparate parts that must be plugged together
Core Design Contradiction:
ProductivityVSDevice complexity

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.

Inventive Principle:
Principle #5Merging (Combining)

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.

Inventive Principle:
Principle #1Segmentation

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

Engineering Contradiction:
Improveflexibility in assembly configurationsVSAvoidsterility and correct assembly
Core Design Contradiction:
Adaptability or versatilityVSReliability

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.

Inventive Principle:
Principle #5Merging (Combining)

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

Engineering Contradiction:
Improveloose attachment of atomizerVSAvoidconnection stability during transportation
Core Design Contradiction:
Ease of manufactureVSReliability

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.

Inventive Principle:
Principle #10Preliminary action
