Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing catheter packages are difficult for users with compromised dexterity to open and access the catheter in a sterile manner, as they require manipulation and extraction of the catheter from a sealed package, which can lead to contamination and ease of use issues.

Innovation Solution

A catheter package design featuring an elongated housing with a closed proximal end and an openable lid that includes a lifting member, which partially lifts the catheter out of the package upon opening, allowing for easy and hygienic retrieval by presenting the catheter for removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the package is sealed to maintain sterility, then the sterility is improved, but the ease of opening and access is worsened

Engineering Contradiction:

ImprovesterilityVSAvoidease of opening

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The lifting member is pre-positioned inside the sealed package, attached to the lid and extending toward the catheter. When the lid is opened, the lifting member automatically engages and begins to lift the catheter, eliminating the need for manual manipulation to extract the catheter from the sealed package.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The lifting member acts as an intermediary mechanism between the lid and the catheter. It transfers the motion of opening the lid into a lifting action that automatically presents the catheter for removal, bridging the gap between maintaining sterility through sealing and enabling easy access.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If manual manipulation is required to extract the catheter, then the ease of removal is improved, but the risk of contamination is worsened

Engineering Contradiction:

Improveease of removalVSAvoidcontamination risk

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The package system performs the catheter extraction action automatically through the lifting member mechanism. When the lid is opened, the lifting member self-activates and lifts the catheter without requiring the user to manually reach into the package and manipulate the catheter, thereby reducing contamination risk while maintaining ease of removal.

Inventive Principle:

Principle #25Self-service

3Reliability

If the catheter remains fully enclosed in the package, then the sterility is improved, but the accessibility for retrieval is worsened

Engineering Contradiction:

ImprovesterilityVSAvoidaccessibility

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The lifting member is pre-configured within the sealed package to automatically engage the catheter upon lid opening. This preliminary positioning ensures that as soon as the package is opened, the catheter is immediately lifted and presented for retrieval, maintaining sterility during storage while providing instant accessibility upon opening.

Inventive Principle:

Principle #10Preliminary action
