Rotating Multi-Screen Tissue Reducer for Enzyme-Free Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for separating tissues and substances from living tissues, such as fat tissues, often rely on enzymes that pose safety concerns due to toxicity, and there is a need for a safer and more efficient method to obtain substances for regeneration and cosmetic treatments.
Innovation Solution
A screen changing device with multiple screens of varying sizes and shapes is used to reduce the size of living tissues, allowing for seamless transition between screens without separating containers, utilizing a system of connectors and housings that rotate to align different screens for pressurization and tissue reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple screens are used to reduce tissue size, then tissue processing effectiveness is improved, but device complexity increases
Solution Approach 1:
The second housing is designed to rotate relative to the first housing, allowing dynamic switching between multiple screens. This rotational mechanism enables the device to process different tissue types and sizes by selecting appropriate screens, thereby improving tissue processing effectiveness while maintaining a relatively simple overall structure through motion-based functionality rather than multiple fixed components
Solution Approach 2:
The device divides the screening function into multiple discrete screens with different aperture sizes and configurations. Each screen is positioned in a separate recess within the second housing, allowing independent selection and optimization for specific tissue processing requirements. This segmentation enables effective handling of various tissue types without requiring a completely different device for each application
2Ease of operation
If screens are changed by separating containers, then screen replacement is simplified, but operational time increases
Solution Approach 1:
The rotational mechanism allows screens to be switched by simply rotating the second housing to a different angular position, bringing the desired screen into alignment with the connectors. This dynamic switching method eliminates the time-consuming process of separating and reassembling containers while maintaining ease of operation through intuitive rotational movement
Solution Approach 2:
Multiple screens are pre-positioned in different recesses of the second housing at specific angular intervals. The connectors are pre-configured in the first housing to align with these recesses at predetermined positions. This preliminary arrangement allows for rapid screen changes by simply rotating to the appropriate position without requiring complex manipulation or container separation
3Device complexity
If connectors are integrated into housings, then device structure is simplified, but screen alignment precision may decrease
Solution Approach 1:
The rotational mechanism incorporates alignment features such as guide grooves, positioning pins, or keyed interfaces that ensure the second housing rotates to precise angular positions. These dynamic alignment features maintain accurate connector-to-screen alignment throughout the rotation, preserving manufacturing precision while allowing for flexible screen selection and simplified integrated structure

AI summary
A screen changing device is proposed. The screen changing device includes a first housing and a second housing configured to be rotated with respect to the first housing. The screen changing device can transit from a first configuration in which a first screen is aligned with a first connector and a second connector to a second configuration in which the first screen is not aligned with the first connector and the second connector and a second screen is aligned with the first connector and the second connector.
