Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing storage solutions for guide wires and catheters during endovascular procedures are unstable, prone to tangling, and risk cross-contamination, with difficulties in selecting the correct device and secure disposal of contaminated fluids.

Innovation Solution

A stable, molded storage platform (Endobin) with a 2:1 diameter-to-height ratio, featuring a base with rotating baffles for separate device storage, a center reservoir for fluid containment, and a snap-on lid for secure disposal, preventing tangling and ensuring sterile handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If multiple catheters are stored together in a single tube, then storage space is optimized, but cross-contamination and tangling occur

Engineering Contradiction:

Improvestorage space utilizationVSAvoidsterility maintenance

Core Design Contradiction:

Area of stationary objectVSReliability

Solution Approach 1:

The storage device is divided into multiple separate compartments or slots within a single container. Each compartment can hold individual catheters or guide wires, preventing them from touching each other while maintaining organized storage. This segmentation approach resolves the contradiction by providing both space efficiency and contamination prevention.

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If catheters are stored in an open bowl, then accessibility is improved, but stability and spill risk increase

Engineering Contradiction:

Improvedevice accessibilityVSAvoidstorage stability

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

The device uses a flexible, collapsible bag or pouch with a funnel-shaped opening that can be sealed. This allows the container to adapt its shape for stability while providing controlled access to stored items. The flexible material prevents spilling while maintaining ease of retrieval through the funnel opening.

Inventive Principle:

Principle #30Flexible shells and thin films

3Reliability

If guide wires are coiled by hand and stored under a sterile towel, then sterility is maintained, but handling difficulty and tangling increase

Engineering Contradiction:

Improvesterility maintenanceVSAvoidwire handling

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The device incorporates a nested structure where a funnel-shaped access opening is integrated into the storage container. The funnel allows easy insertion and retrieval of coiled wires while the entire assembly remains contained within a stable, sealable bag structure, maintaining sterility without handling difficulties.

Inventive Principle:

Principle #7Nested doll (Nesting)
