Syringe Bead Concentration for Biological Material Processing

Solution Overview

Problem

Current devices for processing biological materials are complex, costly, and require multiple processing steps, often resulting in product loss due to timely centrifugation processes.

Innovation Solution

A device comprising a syringe barrel with desiccating or polyacrylamide beads and a filter, along with a plunger assembly that mixes the biological material with the beads, allowing for efficient processing and concentration of biological materials with fewer steps, using a syringe-like mechanism for aspiration and administration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple centrifugation steps are used to process biological materials, then the desired product can be obtained, but the processing time increases and product loss occurs

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent extracts the centrifugation function entirely from the processing system and replaces it with a syringe-based manual operation. The biological material is drawn into a syringe containing beads, mixed by manual agitation, and the desired concentrate is obtained without any centrifugation equipment or multi-step separation processes, thereby eliminating processing time delays.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces beads as an intermediary substance within the syringe that facilitates the concentration process. These beads interact with the biological material during manual mixing to enable separation and concentration without requiring centrifugal force, thus replacing complex mechanical separation with a simpler chemical/physical interaction mechanism.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If multiple centrifugation steps are used to process biological materials, then the desired product can be obtained, but product loss increases due to fraction isolation

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The patent removes the need for fraction isolation steps by performing the entire concentration process within a single syringe. The biological material is mixed with beads directly in the syringe, and the concentrate is obtained by simple aspiration or gravity flow, eliminating the multiple transfer and isolation steps that cause product loss in centrifugation-based systems.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent combines multiple processing functions (mixing, separation, concentration) into a single integrated syringe system. All operations occur within the same container without transferring material between different equipment or vessels, thereby preventing product loss that occurs during fraction isolation and transfer operations in traditional centrifugation protocols.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If complex processing devices are used to process biological materials, then the desired processing can be achieved, but the device cost and complexity increase

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent creates a universal syringe-based device that can process various biological materials (blood, bone marrow, adipose tissue) through the same basic mechanism. The single syringe design with beads performs mixing, separation, and concentration functions that would otherwise require multiple specialized devices, thereby reducing overall system complexity while maintaining processing capability.

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

Solution Approach 2:

The patent employs a disposable syringe-based system that eliminates the need for expensive, complex, reusable processing equipment. The single-use nature of the syringe with integrated beads provides a cost-effective alternative to costly centrifugation machines and associated consumables, reducing both device complexity and overall processing cost.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

4Reliability

If complex processing devices with multiple steps are used, then the desired product can be obtained, but the processing scheme becomes elaborate and difficult to use

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent extracts the complex multi-step processing scheme and replaces it with a single-step syringe-based operation. The biological material is simply drawn into the syringe, mixed by agitation, and the concentrate is obtained by aspiration or gravity flow, eliminating the elaborate sequence of centrifugation steps and making the process easy to perform.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The syringe-based system is designed to be self-contained and self-operating. The beads within the syringe automatically interact with the biological material during manual mixing, and the separation and concentration occur passively through gravity or simple aspiration without requiring complex control mechanisms or multiple operational steps, thereby simplifying the user interface and operation.

Inventive Principle:
Principle #25Self-service
