Tissue Reduction Plate with Protruding Edges for Fat Implantation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices struggle to effectively reduce the size of large fat tissue for implantation due to its fibrous nature, which makes it difficult to pass through fine needles.
Innovation Solution
A device featuring a plate with through holes defined by edges that include protrusions, which scratch and tear the tissue as it passes through, reducing its size through a combination of mechanical scratching and tearing mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a fine needle is used for implantation, then the precision of implantation is improved, but the ability to pass large fat tissue is worsened
Solution Approach 1:
The device segments the fat tissue into smaller particles by forcing it through a screen with multiple protrusions. The screen divides the large tissue mass into manageable fragments that can subsequently be injected through fine needles, resolving the contradiction between tissue size and implantation precision.
Solution Approach 2:
The device performs preliminary size reduction of the fat tissue before implantation. By pre-processing the tissue through mechanical scratching and tearing actions, the device prepares the tissue in advance to be compatible with fine needle injection, eliminating the need to choose between large tissue and fine needles.
2Length of moving object
If mechanical scratching and tearing is applied to reduce tissue size, then the tissue miniaturization is improved, but the device complexity is worsened
Solution Approach 1:
The screen features localized protrusions at specific positions rather than a uniformly complex structure. These protrusions are strategically placed to create effective scratching and tearing actions, achieving tissue size reduction with a relatively simple overall device structure.
Solution Approach 2:
The protrusions on the screen automatically perform the scratching and tearing functions as tissue passes through, without requiring additional moving parts or complex mechanisms. The structure serves its own function through its geometric configuration alone, minimizing device complexity.
