Simulated Body Tissue Model with Embedded Fabric Layers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current simulated body tissue models lack realistic structural support and durability for repeated use in clinical procedures, particularly in mimicking the structural characteristics of human skin and underlying tissues.
Innovation Solution
A simulated body tissue model comprising multiple layers, including a first layer to mimic skin, a second layer to simulate dermis, and embedded fabric layers to provide structural support and elasticity, mimicking the mesh-like network of collagen and elastin fibers, enhancing realism and durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If simulated body tissue models use simple layered structures, then manufacturing is easier, but structural support and durability are insufficient
Solution Approach 1:
The patent applies composite materials by embedding fabric layers (first fabric layer 5, second fabric layer 15, third fabric layer 21) within silicone rubber layers (second layer 4, third layer 12, fourth layer 18) to create a composite structure that mimics human tissue. This combination provides both structural support and durability while maintaining tissue-like properties, resolving the contradiction between strength and complexity.
2Reliability
If simulated body tissue models lack embedded structural layers, then manufacturing is simpler, but durability for repeated use is reduced
Solution Approach 1:
The fabric layers are embedded within the silicone rubber layers during the manufacturing process itself, before the final product is completed. This preliminary embedding action ensures durability for repeated use while avoiding the need for separate post-manufacturing assembly steps, thus maintaining ease of manufacture.
3Manufacturing precision
If simulated body tissue models use multiple embedded fabric layers, then realism and tactile characteristics improve, but manufacturing complexity increases
Solution Approach 1:
Different fabric layers are strategically positioned within specific silicone rubber layers to provide localized structural support where needed. The first fabric layer 5 is embedded in the second layer 4, the second fabric layer 15 in the third layer 12, and the third fabric layer 21 in the fourth layer 18, creating local quality variations that enhance realism without requiring complex overall restructuring.
