Solution Overview

Problem

Existing multi-component fluid product delivery systems, such as syringes and vials, face issues with environmental sustainability, connection security, accurate liquid withdrawal, and ergonomic handling, particularly in the medical and pharmaceutical fields.

Innovation Solution

A single-component injection molded vial with a male luer lock fitting that integrates ergonomic design principles, allowing it to function as both a suction pump and dispensing device, and can be used as a sterile container, with features like a frangible closure or separate cap for sealing and dispensing fluid products.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple components are used to create luer fitting devices, then functional versatility is achieved, but environmental sustainability deteriorates due to difficulty in recycling mixed materials

Engineering Contradiction:

Improvefunctional versatilityVSAvoidenvironmental sustainability

Core Design Contradiction:

Adaptability or versatilityVSLoss of substance

Solution Approach 1:

The patent merges multiple previously separate components (vial body, cap, and luer lock fitting) into a single integrated component molded from one piece of plastic. This eliminates material incompatibility issues in recycling while maintaining all necessary functions including fluid containment, connection to luer fittings, and dosing capabilities

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The single-component design incorporates multiple functions within one structure: the vial body contains fluid, the integrated cap seals the opening, and the built-in luer lock fitting enables connection to syringes and other medical devices. This multi-functionality replaces what previously required separate components

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple components are assembled together, then functional capabilities are achieved, but connection security deteriorates due to difficulty in securing connections between components

Engineering Contradiction:

Improvefunctional capabilitiesVSAvoidconnection security

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The luer lock fitting is molded as an integral part of the vial assembly, eliminating the need to assemble separate fitting components. This integration ensures that the connection interface is permanently secured and cannot become loose or disconnected during use

Inventive Principle:

Principle #5Merging (Combining)

3Adaptability or versatility

If traditional multi-component systems are used, then device functionality is achieved, but ease of operation deteriorates due to difficulty in dispensing product with one hand

Engineering Contradiction:

Improvedevice functionalityVSAvoidease of dispensing

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The cap and luer lock fitting are merged into a single operable unit that can be manipulated with one hand. The integrated design allows the user to grip and operate the entire assembly without needing to coordinate separate components, simplifying the dispensing action

Inventive Principle:

Principle #5Merging (Combining)

4Adaptability or versatility

If traditional vial designs are used, then manufacturing capabilities are achieved, but ease of manufacture deteriorates due to limitations in manufacturing strips of vials

Engineering Contradiction:

Improvemanufacturing capabilitiesVSAvoidease of manufacturing strips

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The single-component design allows vials to be molded individually or in strips using standard injection molding techniques. The integrated structure eliminates the need for separate assembly operations, making it easier to manufacture strips of vials compared to multi-component designs that require post-molding assembly

Inventive Principle:

Principle #5Merging (Combining)
