Angled Cutter Mounting Block for Medical Waste Sterilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical waste treatment equipment is prone to tool wear and damage due to the presence of metal in the waste, which reduces crushing efficiency and requires frequent cutter replacements.
Innovation Solution
A tool-integrated medical waste sterilization processing barrel with a truncated square pyramid mounting block and angled cutters that bounce off metal waste, reducing direct contact and wear, combined with a rotating mechanism for efficient discharge and waste distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional crushers with horizontal cutters are used, then crushing function is provided, but tool wear increases due to metal contact
Solution Approach 1:
The patent changes the spatial orientation parameter of the cutters from horizontal to angled (inclined at 45 degrees to the horizontal plane). This parameter change allows cutters to bounce off metal objects rather than crush them directly, significantly reducing tool wear while maintaining crushing effectiveness for organic waste.
Solution Approach 2:
The mounting block is designed with a truncated square pyramid shape featuring inclined surfaces, creating an angled geometry for cutter placement. This curved/angled structural design enables the cutter bounce-off mechanism that reduces direct contact with metal objects, improving tool durability without sacrificing productivity.
2Reliability
If frequent cutter replacement is performed, then tool wear is managed, but processing time increases
Solution Approach 1:
By changing the cutter orientation to an angled configuration mounted on an inclined surface, the patent reduces the rate of tool wear. This extends the operational lifespan of cutters, significantly reducing the frequency of replacements needed and minimizing operational interruptions for maintenance.
3Ease of manufacture
If cutters are placed parallel to the bottom surface, then installation is simple, but metal damage to cutters occurs
Solution Approach 1:
The patent employs an inclined mounting surface (truncated square pyramid structure) at 45 degrees to the horizontal plane, creating an angled installation configuration. This geometric design allows cutters to naturally bounce off metal objects during operation, protecting them from direct impact damage while remaining manufacturable.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The angled cutters minimize tool wear and enhance crushing efficiency, while the rotating mechanism facilitates easy discharge of crushed waste, reducing accumulation and improving overall processing efficiency.
Implementation Method 1
an annular electromagnetic sliding chute provided at the bottom of the treatment barrel, two symmetrically provided electromagnetic sliders slidingly connected in the electromagnetic sliding chute
