Homogenizer With Elastic Force Absorber For Hard Tissue
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional homogenizers often experience crushing failures when processing hard tissue samples due to excessive pressing force, which can cause the crushing tool to become stuck and fail to rotate effectively.
Innovation Solution
A homogenizer design incorporating an elastic member that absorbs excessive pressing force, allowing for adjustable deformation to manage the force applied to the tissue sample, along with a support part and second driver to control the movement of the crushing part, preventing integration with the tissue sample and enabling separation to avoid crushing failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the inner crushing member is pressed with excessive force against the tissue sample, then the crushing effectiveness is improved, but the inner crushing member may bite into the lymph node and become stuck, resulting in crushing failure
Solution Approach 1:
The inner crushing member is designed to be movable in the vertical direction relative to the outer crushing member, transitioning between a working position (inserted into the sample container) and a retraction position (withdrawn from the sample container). This dynamic positioning allows the system to adapt to varying tissue hardness, preventing the crushing member from becoming stuck while maintaining effective crushing during operation
Solution Approach 2:
The system performs preliminary actions by repeatedly moving the inner crushing member between the working position and retraction position before complete crushing is achieved. This preliminary reciprocating motion prevents the crushing member from biting into hard tissue and becoming stuck, while still effectively breaking down the tissue sample over multiple cycles
2Productivity
If the inner crushing member is rotated at high speed, then the crushing efficiency is improved, but the crushing member may integrate with the tissue sample and fail to separate, causing crushing failure
Solution Approach 1:
The inner crushing member performs periodic reciprocating movements between the working position and retraction position during rotation. This periodic action interrupts continuous rotation, preventing the crushing member from integrating with the tissue sample while maintaining high crushing efficiency through repeated contact and separation cycles

Function Achieved in This Case
The solution effectively suppresses crushing failures by maintaining appropriate pressing force and allowing for efficient tissue sample processing, even with hard samples, while preventing the blender from becoming stuck and ensuring complete crushing.
Implementation Method 1
The absorbing means includes an elastic member that contracts when the blender is pressed against the tissue sample in the container

AI summary
Disclosed is a homogenizer comprising: a crushing part having a blender for crushing a tissue sample in a container; a rotation driver configured to rotate the blender in contact with the tissue sample; and an absorbing part for absorbing a pressure applied to the tissue sample, which is caused when the blender comes into contact with the tissue sample.
