Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for processing platelet rich fibrin are inefficient in compressing fibrin clots to uniform thicknesses, often resulting in wasted serum and difficulty in achieving desired thicknesses for medical applications, and lack the ability to easily combine multiple clots.
Innovation Solution
A tray system with a base, screen attachment, and lid that allows for the alignment and compression of fibrin clots to specific thicknesses, utilizing a tapered interior receptacle to direct serum for collection and a reversible screen orientation to achieve multiple thickness settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a fibrin clot is compressed manually or with simple devices, then serum can be expressed, but the compression is inefficient and serum is wasted
Solution Approach 1:
The device segments the compression process into controlled stages using a plunger mechanism that applies gradual, uniform pressure. The screen attachment divides the clot into manageable portions on the screen surface, allowing systematic compression and serum expression without waste.
Solution Approach 2:
The screen attachment acts as an intermediary between the clot and the compression force. It distributes pressure evenly across the clot surface while allowing serum to pass through, preventing direct contact that would cause uneven compression and serum loss.
2Manufacturing precision
If a thick fibrin clot is compressed, then serum is expressed, but it is difficult to achieve uniform thin thickness
Solution Approach 1:
The screen attachment provides locally optimized compression by conforming to the clot surface and applying pressure through its mesh structure. This ensures uniform thickness reduction across the entire clot surface, transforming thick irregular clots into uniformly thin layers suitable for medical use.
3Adaptability or versatility
If multiple platelet rich fibrins are combined, then desired thickness can be achieved, but the process becomes complex
Solution Approach 1:
The device is designed to handle multiple clots simultaneously on the screen surface, allowing combination of several platelet rich fibrins in a single compression cycle. This universal approach achieves variable thickness requirements without complex multi-step procedures.
4Productivity
If serum is expressed during compression, then platelet rich fibrin is formed, but the expressed serum is wasted
Solution Approach 1:
The device recovers the serum that would otherwise be discarded during compression. The collection well captures expressed serum, and the outlet provides access for removal and potential reuse, eliminating substance loss while maintaining efficient fibrin formation.

Function Achieved in This Case
Enables efficient compression of fibrin clots to uniform thicknesses, allowing for the simultaneous collection of serum and flexible use of platelet rich fibrin in medical procedures, including wound healing and suturing, by directing serum flow and enabling adjustable clot thickness.
Implementation Method 1
The lid is configured to compress a fibrin clot placed on the screen to a first thickness
Implementation Method 2
The interior receptacle is tapered and slanted toward the front access opening such that liquid flowing through the screen and into the interior receptacle is directed toward the front access opening
Implementation Method 3

AI summary
A tray for processing platelet rich fibrin includes a base having at least one alignment structure, a screen attachment having at least one alignment structure for engagement with the base, and a lid having at least one alignment structure for engagement with the base and the screen attachment. The screen attachment includes a screen offset between the top and bottom surface of the screen. When the screen attachment is placed on the base with the top surface facing upward, the lid is configured to compress a fibrin clot placed on the screen to a first thickness, and when the screen attachment is placed on the base with the bottom surface facing upward the lid is configured to compress a fibrin clot placed on the screen to a second thickness different from the first thickness.
