Solution Overview
Problem
Existing devices for body fat transplantation require multiple pieces of equipment for different method steps, making the process complex, unsafe, and inflexible.
Innovation Solution
A device with a partially hollow-cylindrical chamber divided into proximal and distal sections, using a plunger with a piston that includes a filter and media connections for suction and injection, allowing for the use of negative and positive pressures to manage infiltration, suction, and reinjection of body fat in a single, flexible, and safe manner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate equipment are used for different method steps (infiltration, suction, reinjection), then each step can be performed with specialized equipment, but the overall process becomes complex and requires multiple devices
Solution Approach 1:
The patent combines infiltration, suction, and reinjection functions into a single integrated device. The device includes a chamber with a movable partition that can be displaced to perform different operations: moving the partition in one direction enables infiltration and suction, while moving it in the opposite direction enables reinjection. This eliminates the need for multiple separate equipment and simplifies the overall system while maintaining functional reliability
Solution Approach 2:
The single device is designed to perform multiple functions through a universal chamber structure. The chamber can accommodate different operational modes (infiltration, suction, reinjection) by simply changing the displacement direction of the movable partition. This multi-functional design allows one device to replace multiple specialized equipment, reducing system complexity while maintaining the reliability of each individual function
2Device complexity
If a single device is used for all method steps, then device complexity is reduced and handling is simplified, but flexibility for different operations may be limited
Solution Approach 1:
The device employs a dynamic movable partition that can be displaced bidirectionally within the chamber. This dynamic element allows the device to adapt between different operational modes (infiltration, suction, reinjection) without requiring structural changes. The partition's ability to move in both directions provides the flexibility needed for different operations while maintaining a simple single-device structure
Solution Approach 2:
The device achieves flexibility through parameter changes in the chamber pressure and partition position. By changing the displacement direction and magnitude of the movable partition, the device can switch between different operational parameters (suction pressure, infiltration pressure, reinjection flow rate). This allows a single device to adapt to different operational requirements without compromising versatility
3Reliability
If separate equipment is used for each step, then each device can be optimized for its specific function, but handling and operation become more difficult
Solution Approach 1:
By merging infiltration, suction, and reinjection functions into one device with a unified chamber and control mechanism, the patent improves ease of operation. The operator handles a single device rather than multiple separate equipment, simplifying the operational workflow while maintaining the specialized functionality needed for each step through the movable partition mechanism
