Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional centrifugal separation containers are used, then separation function is provided, but material injection and discharge become complex with long paths

Engineering Contradiction:
Improvematerial injection and dischargeVSAvoidconnection complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The container is divided into multiple chambers (first chamber, second chamber, third chamber) with distinct functions for injection, separation, and discharge. Each chamber has dedicated ports and valves, segmenting the material flow paths to simplify connections and operations while maintaining separation efficiency

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A valve mechanism acts as an intermediary between chambers to control material flow. The valve selectively opens and closes passages between chambers, enabling simple external connections while managing complex internal flow paths through automated control

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If traditional centrifugal separation containers are used, then separation is achieved, but backflow occurs during centrifugation

Engineering Contradiction:
Improveseparation process stabilityVSAvoidbackflow
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The valve is pre-configured in a closed state before centrifugation begins. This preliminary action prevents backflow from occurring during the centrifugal process, ensuring reliable separation without the harmful backflow effect that plagues traditional containers

Inventive Principle:
Principle #10Preliminary action

3Productivity

If traditional centrifugal separation containers are used, then separation is performed, but extracts remain in containers after extraction

Engineering Contradiction:
Improveextract recovery efficiencyVSAvoidextract remaining in container
Core Design Contradiction:
ProductivityVSLoss of substance

Solution Approach 1:

The design enables complete extraction of separated materials from the container through dedicated discharge ports and channels. The valve system controls complete evacuation of extracts from all chambers, eliminating the problem of residual extracts remaining in traditional containers after separation

Inventive Principle:
Principle #2Taking out (Extraction)

4Manufacturing precision

If washing process is added to traditional containers, then extract purity can be improved, but operation complexity increases

Engineering Contradiction:
Improveextract purityVSAvoidwashing operation
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The washing function is merged into the existing multi-chamber structure. The second chamber serves dual purposes as both a separation chamber and a washing chamber, receiving wash materials through dedicated ports. This integration allows purity improvement without adding separate washing equipment or complex external connections

Inventive Principle:
Principle #5Merging (Combining)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The design enables efficient and balanced operation, allowing for easy injection, separation, and discharge of materials while maintaining high-purity extracts, improving the overall efficiency and simplicity of the centrifugal separation process.

Implementation Method 1

The centrifugal separators use a centrifugal separation container that accommodates specific tissue and body fluids and is rotatably configured to perform centrifugation. In the centrifugal seperation container, tissue and body fluids are accommodated, and when it rotates on a predetermined rotation shaft, materials in the tissue and body fluids are separated by a centrifugal force.

Methodology Applied
Scientific EffectCentrifugal force: Centrifugal Force

Implementation Method 2

An elastic member is also arranged between the first vessel and the second vessel, elastic-deforming depending on the relative position of the two vessels, and generating a biasing force opening the through-hole by the valve member when the centrifugal force acting in the axial direction turns to a predetermined value or less.

Methodology Applied
Scientific EffectElastic deformation: Elasticity
