Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If external suction sources and components are used for fat harvesting, then fat collection capability is improved, but contamination risk increases and device complexity increases
Solution Approach 1:
The patent combines the suction source, fat harvesting components, processing system, and injection system into a single integrated device. The suction source is incorporated directly into the device body, eliminating the need for external suction sources and reducing contamination risk from multiple external connections. This merged system maintains fat collection capability while improving sterility and reducing complexity.
Solution Approach 2:
The integrated device performs multiple functions including fat harvesting, processing, sizing, and injection within a single system. The device can operate in various settings (surgical suites, office environments, mobile clinics) without requiring separate external components, thereby reducing contamination opportunities while maintaining full functionality.
2Productivity
If external suction sources are required, then fat harvesting function is improved, but ease of operation decreases due to limited settings
Solution Approach 1:
The device is designed to be self-contained with an integrated suction source that operates independently without requiring external connections. The system includes built-in processing and injection capabilities that can function autonomously, allowing operation in diverse settings including office environments and mobile clinics, thereby significantly improving ease of operation while maintaining fat harvesting function.
3Object-affected harmful factors
If a single self-contained device is used, then contamination risk is reduced, but device complexity increases
Solution Approach 1:
The device is divided into distinct functional modules including a suction source module, fat processing module, sizing module, and injection module. Each module can be independently designed, manufactured, and sterilized, which manages the complexity through modular architecture while maintaining the benefits of a single self-contained system that reduces contamination risk.
4Adaptability or versatility
If fat cells are processed outside a controlled environment, then flexibility in settings is improved, but manufacturing precision (sizing accuracy) deteriorates
Solution Approach 1:
The sizing mechanism is integrated directly into the fat processing chamber within the self-contained device. This allows precise sizing control in a controlled sterile environment while the entire device can be transported and used in various settings including office environments and mobile clinics. The merged design ensures sizing accuracy is maintained regardless of the external location.
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 system effectively reduces contamination risks, enables sterile fat harvesting and sizing in various settings, including non-surgical environments, and provides flexibility in fat cell sizing for tailored reinjections, enhancing the safety and efficacy of fat transfer procedures.
Implementation Method 1
the fat cells residing in a device reservoir can be decanted to separate an 'oily' layer containing the fat cells from an aqueous layer containing blood, serum and other biological components
Implementation Method 2
the fat cells can be sized or 'morcellized' by directing a sizing screen through the device reservoir such that the fat cells achieved the medical professional's desired size for reinjection

AI summary
A fat harvesting systems and related methods of harvesting and reinjecting fat that provides a medical professional with multiple technique options. Harvested fat can be subjected to a variety of pre-reinjection preparation steps within a single, self contained reservoir such that the potential for contaminating the harvested fat is avoided. The fat harvesting system can be completely self-contained kit requiring no additional external systems or alternatively, can utilize available surgical suite systems, for example, vacuum to successfully harvest, prepare and reinject fat cells. The fat harvesting system can size harvested fat cells so as to be especially desirable for different injection locations in the body. The fat harvesting system is a single use, disposable system that requires no sterilization equipment and recovered and sized fat cells are maintained in a sanitary environment so as to avoid contamination that could result in having to discard recovered fat cells.
