Engineering Contradictions & Design Principles
Engineering 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
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
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
2Reliability
If traditional centrifugal separation containers are used, then separation is achieved, but backflow occurs during centrifugation
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
3Productivity
If traditional centrifugal separation containers are used, then separation is performed, but extracts remain in containers after extraction
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
4Manufacturing precision
If washing process is added to traditional containers, then extract purity can be improved, but operation complexity increases
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
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.
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.
