Solution Overview
Problem
Existing graft packaging systems are inadequate for efficiently separating and removing excess fluid from hydrated grafts, which is crucial for maintaining optimal handling properties and preparation for medical treatments.
Innovation Solution
A multi-component packaging system is introduced, featuring a graft holding region, a reservoir region, and fluid communication means, along with compression features that apply force to separate and displace fluid from the graft, facilitating efficient fluid removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single-component packaging system is used, then the device complexity is low, but the ability to efficiently separate and remove excess fluid from hydrated grafts is insufficient
Solution Approach 1:
The packaging system is divided into distinct functional components: a graft holding region for containing the graft, a reservoir region for collecting excess fluid, and fluid communication means for enabling fluid transfer between regions. This segmentation allows each component to perform its specific function efficiently, improving fluid separation capability while maintaining manageable complexity through modular design.
2Productivity
If compression features are added to separate fluid from graft, then the fluid removal efficiency is improved, but the device complexity increases
Solution Approach 1:
The compression feature is integrated within the packaging system structure, combining the fluid separation function with the existing graft holding and reservoir regions. The compression element works in conjunction with the fluid communication means and reservoir region to create a unified system that removes excess fluid efficiently without requiring entirely separate equipment, thus improving productivity while controlling complexity.
3Reliability
If multi-component packaging system is used, then the graft condition maintenance capability is improved, but the ease of operation deteriorates
Solution Approach 1:
The packaging system is designed to perform multiple functions within a single integrated structure: maintaining graft condition through controlled environment, enabling fluid communication between regions, providing compression for fluid separation, and collecting excess fluid in the reservoir region. This multi-functionality allows the system to maintain reliable graft condition while minimizing the number of separate operations required, thereby improving ease of operation despite the multi-component nature.

Function Achieved in This Case
The packaging system effectively separates and removes excess fluid from hydrated grafts, enhancing the graft's handling properties and preparation for medical use by minimizing oversaturation and improving cohesiveness and moldability.
Implementation Method 1
one or more compression features for applying compressive force to a graft while held in the graft holding region and causing displacement of fluid from the graft

AI summary
A multi-component packaging system capable of holding a graft and fluid therein, and which enables separation and removal of fluid from the graft, hydration of the graft by adding fluid, or both, while the graft is held in the packaging system. The packaging system comprises: a graft holding region for holding the graft and, optionally, a fluid; a reservoir region for receiving and containing fluid separated from the graft; a container configured to hold the graft, prevent contamination, and which defines the reservoir region. The packaging system further comprises: at least one fluid separation feature for enabling separation of fluid from the graft; at least one compression feature for applying compressive force to assist with more efficient separation of fluid from the graft and displacement of separated fluid from the graft holding region and into the reservoir region, and at least one fluid communication means which allows displaced fluid to leave the graft holding region and enter the reservoir region.
