Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual preparation of adipose tissue is performed by operators, then flexibility and adaptability are maintained, but manufacturing precision and reliability deteriorate due to potential errors and lack of reproducibility
Solution Approach 1:
The patent replaces manual mechanical preparation operations with an automated centrifugal purification system. The device uses a centrifugal mechanism to automatically separate adipose tissue from contaminants and washing liquid, eliminating operator involvement and ensuring reproducible results. The centrifugal force field automatically performs the separation function that previously required manual handling and filtering operations.
2Productivity
If manual preparation methods are used, then operational flexibility is maintained, but productivity deteriorates due to time-consuming procedures and high operational costs
Solution Approach 1:
The centrifugal purification device performs the separation function automatically without requiring operator intervention during the purification process. The system self-regulates the centrifugal separation, automatically discharges contaminants through the filter, and prepares the adipose tissue for collection. This self-service capability significantly improves productivity by eliminating manual preparation steps while maintaining operational simplicity through automated control.
3Manufacturing precision
If centrifugal purification is implemented, then manufacturing precision and purity are improved, but device complexity increases due to additional mechanical components
Solution Approach 1:
The centrifugal mechanism serves multiple functions simultaneously: it provides the centrifugal force field for separation, drives the rotation of the filter for contaminant discharge, and controls the overall purification process timing. This multi-functionality reduces the need for separate mechanical components for each function, thereby limiting the increase in device complexity while achieving high purification precision through centrifugal separation.
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 device simplifies and enhances the reliability of adipose tissue purification, reducing resorption rates and operational costs by automating the process while maintaining high tissue quality.
Implementation Method 1
the ends of the filter are connected to separate attachment elements whose movement is controlled differently by the drive system depending on whether it is desired to purify the adipose tissue or to carry out the discharge. Thus, in the purification configuration, the lower and upper ends of the filter rotate together, which leads to centrifugation of the adipose tissue against the internal wall of the filter
Implementation Method 2
a flexible filter delimiting a treatment volume and being able to retain the adipose tissue and to filter a liquid medium
Implementation Method 3
when the drive system is put into the discharge configuration, one end of the filter is rotated with relative movement with regard to the other end, which can be fixed by being no longer engaged with the drive system. This causes the filter to wind on itself from its upper end (area of least stress with no adipose tissue, or less adipose tissue than in the lower end) to its lower end. This winding applies discharge pressure that pushes purified adipose tissue into the discharge duct
