There is a need for devices and methods to extract and concentrate therapeutically active factors from mammalian tissues and biological fluids without relying on traditional centrifuges, which are often not accessible in all surgical sites.

Innovation Solution

A handheld system comprising containment devices connected to a motor source that can spin along various axes, allowing for the concentration, purification, and fractionation of biological samples using adjustable g-forces, and can be operated independently in surgical settings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional centrifuges are used to separate and concentrate biological samples, then separation efficiency and concentration capability are improved, but device accessibility and portability deteriorate

Engineering Contradiction:
Improveseparation efficiencyVSAvoiddevice accessibility
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The system divides the traditional centrifuge functionality into modular components: a handheld motor unit that can be detached from the containment device. This segmentation allows the motor source to be transported separately and attached only when needed, improving accessibility while maintaining separation efficiency

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The motor source is extracted from the traditional centrifuge structure and made handheld, allowing it to be removed from fixed laboratory settings. The motor unit can be taken to surgical sites and attached to containment devices as needed, resolving the contradiction between maintaining centrifugation capability and improving portability

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of operation

If handheld motor sources are used to spin containment devices, then device portability and accessibility are improved, but processing speed and g-force consistency deteriorate

Engineering Contradiction:
Improvedevice portabilityVSAvoidprocessing speed
Core Design Contradiction:
Ease of operationVSSpeed

Solution Approach 1:

The handheld motor source is designed to be universally compatible with multiple containment device types and configurations. It can function as a centrifuge, mixer, or other processing device depending on the attached containment device, maintaining processing speed across different applications while preserving portability

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

Solution Approach 2:

The system allows the motor source to be stabilized by the user's hand or by placing the containment device in a base, eliminating the need for complex external stabilization mechanisms. This self-service approach maintains processing speed while keeping the device portable and easy to operate

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If containment devices are designed to freely rotate to horizontal position, then sample processing versatility is improved, but structural stability and control deteriorate

Engineering Contradiction:
Improvesample processing versatilityVSAvoidstructural stability
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The containment device is designed with dynamic characteristics that allow it to freely rotate from vertical to horizontal position during processing. This dynamic design enables versatile sample processing orientations while the system maintains control through the motor source's speed and direction control, resolving the contradiction between versatility and stability

Inventive Principle:
Principle #15Dynamics

4Quantity of substance

If multiple tubular vessels are counter disposed within buckets, then sample processing capacity is improved, but device complexity and assembly difficulty deteriorate

Engineering Contradiction:
Improvesample processing capacityVSAvoiddevice complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

Multiple tubular vessels are nested within buckets that are counter-disposed on the containment device. This nesting arrangement increases sample processing capacity while organizing components in a space-efficient manner that reduces overall device complexity and simplifies assembly

Inventive Principle:
Principle #7Nested doll (Nesting)
