Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

There is a lack of efficient packaging systems for pen needles and syringe needles that allow convenient storage and retrieval of multiple needles while ensuring sterility and ease of use.

Innovation Solution

A strip-based packaging system where multiple needles are attached to a common seal, allowing individual removal and exposure for immediate use, with perforations for separating sections and optional hanger attachments for convenience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple needles are packaged individually with separate tear-drop labels, then sterility is ensured, but user convenience and storage efficiency deteriorate

Engineering Contradiction:

ImprovesterilityVSAvoiduser convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

Multiple individually packaged needles are merged onto a single common seal/strip structure. The strip serves as a shared sterility barrier for multiple needles, eliminating the need for separate tear-drop labels on each needle while maintaining sterility through the continuous sealed environment of the strip.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The common seal/strip structure performs multiple functions simultaneously: it acts as a sterility barrier for multiple needles, provides a storage structure, and serves as a retrieval mechanism. Users can access multiple needles from a single sealed structure rather than handling individual packaged needles.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If multiple needles are stored in individual packages, then sterility is maintained, but storage organization and accessibility worsen

Engineering Contradiction:

ImprovesterilityVSAvoidstorage organization

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

Multiple needle packages are merged into a single organized strip structure with consistent spacing and alignment. This unified structure improves storage organization by providing a standardized layout while maintaining the sterility of each individual needle through the sealed strip environment.

Inventive Principle:

Principle #5Merging (Combining)

3Reliability

If individually packaged needles are used, then sterility is ensured, but retrieval efficiency and time consumption worsen

Engineering Contradiction:

ImprovesterilityVSAvoidretrieval time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

Multiple needles are pre-positioned on the strip in advance during manufacturing, with their packages sealed and organized. This preliminary arrangement allows users to quickly access and retrieve needles without having to search through or repackage individual sterile units, reducing retrieval time while maintaining sterility through the pre-sealed structure.

Inventive Principle:

Principle #10Preliminary action

AI summary

A multiple pen needle or syringe needle storage and dispensing system where a plurality of needle devices such as pen needles including a cover can be disposed on strip, where the strip serves a seal for multiple needle devices. Each needle device can be peeled off the strip unsealed for immediate use for example in an injections device, or separated from the strip sealed for later use.
