Solution Overview

Problem

Current methods for isolating and processing autologous adipose tissue harvested via liposuction are inefficient, traumatic, and lack standard techniques for large-scale refinement, often requiring cumbersome centrifuge-based processes that increase tissue rejection risks.

Innovation Solution

A tissue separating device with a canister and adjustable filtration mesh assembly that separates fatty liposuction aspirate into pure fat and aqueous components, allowing atraumatic collection and reduction of processing steps, maintaining a sterile environment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If centrifuge-based processing is used to separate adipose tissue, then separation efficiency is improved, but tissue trauma increases and processing time extends

Engineering Contradiction:
Improveseparation efficiencyVSAvoidtissue trauma
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the harmful centrifugal force from the processing system and replaces it with a gentle filtration mechanism. The filtration mesh assembly separates adipose tissue from liposuction effluent without subjecting the tissue to high-speed rotation, thereby eliminating centrifuge-induced trauma while maintaining effective separation.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent substitutes the mechanical centrifugal separation system with a filtration-based mechanical system. Instead of using rotational force to separate components, the system employs a filtration mesh that physically filters adipose tissue from fluid components through a different mechanical principle, reducing tissue stress.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Manufacturing precision

If multiple processing steps are used to separate and clean adipose tissue, then tissue purity is improved, but processing time and complexity increase

Engineering Contradiction:
Improvetissue purityVSAvoidprocessing time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent merges multiple separation and cleaning functions into a single integrated filtration mesh assembly. The mesh simultaneously filters adipose tissue from effluent, separates oil-water layers, and prepares tissue for injection in one continuous process, eliminating the need for sequential centrifugation and manual processing steps.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The filtration mesh assembly performs multiple functions: filtering adipose tissue from liposuction effluent, separating oil and water layers, and preparing purified tissue for re-injection. This multi-functional design consolidates what would traditionally require several separate processing stages into one universal device.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Quantity of substance

If traditional liposuction harvesting is used, then tissue collection is achieved, but tissue trauma and contamination risk increase

Engineering Contradiction:
Improvetissue collection volumeVSAvoidtissue contamination
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a sterile filtration mesh assembly as an intermediary between the liposuction harvesting process and tissue preparation. This intermediary component filters and purifies the harvested tissue in real-time, preventing contamination from liposuction effluent while maintaining the collected tissue volume for subsequent re-injection.

Inventive Principle:
Principle #24Intermediary (Mediator)
