Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing needle-free vial adapters pose risks of accidental injuries and contamination due to exposed sharp piercing members, inefficiencies in substance extraction, and insecure connections leading to fluid leakage, while being cumbersome and costly to manufacture and maintain.
Innovation Solution
A needle-less vial assembly with a telescopically engaging substance transfer system that includes a first portion for sealingly engaging with the vial neck and a second portion for matingly engaging with a syringe, featuring a channel for fluid communication, which allows for safe and complete extraction of substances without sharp piercing members and ensures a sealed connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional syringes with needles are used to extract medicine from vials, then extraction efficiency is improved, but the risk of accidental injuries and contamination increases
Solution Approach 1:
The patent removes the needle component entirely from the extraction system, replacing it with a needle-free adapter that interfaces directly with the vial stopper. This extraction of the harmful element (needle) while preserving the functional capability (substance transfer) directly resolves the contradiction between extraction efficiency and safety risk.
Solution Approach 2:
The needle-free adapter serves as an intermediary device between the syringe and the vial stopper. It provides a safe interface that eliminates direct needle exposure while maintaining the substance transfer function, thus resolving the contradiction by introducing a mediating component that removes the harmful element.
2Object-affected harmful factors
If needle-free vial adapters with exposed sharp piercing members are used, then the risk of accidental injuries is reduced, but the capability to extract entire pharmaceutical is compromised
Solution Approach 1:
The patent completely removes the sharp piercing member from the adapter design, replacing it with a safe piercing mechanism that achieves stopper penetration without exposed sharp elements. This maintains safety while improving extraction capability by enabling complete pharmaceutical removal through proper sealing and engagement mechanisms.
3Adaptability or versatility
If adapters are supplied as separate components requiring manual insertion, then adaptability to different vials is improved, but the complexity of operation and potential for malfunction increase
Solution Approach 1:
The patent integrates the adapter design to work with standard vial configurations through telescopic engagement, where the adapter body nests within the vial neck structure. This nested design provides adaptability to different vial sizes while simplifying operation through automatic engagement mechanisms that reduce manual manipulation requirements.
Solution Approach 2:
The adapter incorporates self-aligning and self-sealing features that automatically adjust to different vial configurations without requiring precise manual positioning. The telescopic engagement mechanism self-adjusts to accommodate various vial dimensions, reducing operational complexity while maintaining versatility.
4Adaptability or versatility
If adapters are composed of numerous parts that must be sealed together, then adaptability to different applications is improved, but the manufacturing complexity and cost increase
Solution Approach 1:
The patent combines multiple adapter functions into a single integrated body structure, eliminating the need for numerous separate components that require assembly and sealing. This merged design maintains application versatility through configurable engagement features while dramatically simplifying manufacturing by reducing part count and assembly steps.
Solution Approach 2:
The adapter body is designed as a universal component that performs multiple functions: piercing engagement, sealing, and substance transfer. This multi-functional design eliminates the need for separate specialized components for each function, reducing manufacturing complexity while maintaining adaptability to different vial and syringe configurations.
5Ease of operation
If adapters do not provide sealed connection with syringe, then ease of operation is improved, but product waste due to leakage increases
Solution Approach 1:
The patent implements a continuous sealed connection between the adapter and syringe that maintains fluid integrity throughout the extraction process. The sealing mechanism remains engaged throughout connection and operation, preventing leakage while maintaining ease of operation through straightforward engagement that does not compromise the seal.

AI summary
A needle-less vial assembly that includes a substance transfer assembly configured to telescopically engage with a vial neck of a vial. A first portion of the substance transfer assembly is configured to sealingly engage with an interior wall of the vial neck, where the first portion includes a first inlet configured to receive a substance from the vial. A second portion of the substance transfer assembly is configured to matingly engage with a syringe, and includes an outlet configured to dispense the substance to the syringe. A channel is defined through the first portion and the second portion, thereby enabling fluid communication of the substance from the vial to the syringe via the first inlet and the outlet.
