Solution Overview

Problem

Existing dispensing syringes for reactive materials face challenges in precise application of small quantities, waste due to over-dispensing, hazards from spillage and contamination, and the risk of static mixer separation and cap loss during use and storage, which impairs system utility.

Innovation Solution

A dual-barreled syringe system with a static mixer element and a fixing element, such as a sliding clip, to securely attach the mixer to the syringe, along with a re-sealing mechanism like a cap or plug, ensuring secure attachment and easy reattachment during use and storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the static mixer element is made separable from the syringe assembly, then it can be attached to the open nozzle for use, but it risks becoming permanently separated during use or storage

Engineering Contradiction:
Improveattachment of static mixerVSAvoidretention of static mixer
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The fixing element transitions from a loose state during attachment to a locked state during use and storage. The clip engages with the syringe assembly and static mixer element to create a secure mechanical connection that prevents separation, while still allowing for initial attachment and subsequent removal after use.

Inventive Principle:
Principle #15Dynamics

2Ease of manufacture

If the cap is frangibly molded together with the syringe body, then it is simple to provide re-sealing, but the small cap is susceptible to misplacement and loss

Engineering Contradiction:
Improvere-sealing mechanismVSAvoidretention of cap
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The fixing element serves multiple functions by simultaneously securing both the static mixer element and the cap to the syringe assembly. This merged approach ensures that both small components are retained together during use and storage, preventing misplacement and loss while maintaining the simple frangible molding structure.

Inventive Principle:
Principle #5Merging (Combining)

3Device complexity

If separate nozzles are used for each reactant, then the dispenser structure is simple, but the user must mix components manually which increases waste and hazards

Engineering Contradiction:
Improvedispenser structureVSAvoidspillage and contamination
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The static mixer element acts as an intermediary component that receives the separate reactant streams from the simple dual-nozzle dispenser and internally mixes them through its spiral geometry. This mediator approach maintains the simplicity of the dispenser structure while eliminating the need for manual mixing, thereby reducing waste and hazards associated with spillage and contamination.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A dispensing system for simultaneously dispensing a plurality of reactive materials. The system includes a multiple-barreled syringe having at least two barrels joined by a flange and containing respective different reactive materials. Parallel plungers joined by a flange force sealing members through the barrels to discharge the materials. A static mixer element having an applicator attaches to the syringe, and a means for re-sealing the syringe for subsequent use is provided. A sliding clip engaging a complementary shape removably fixes a loose static mixer element to the syringe, reducing the risk of misplacement and loss.
