Manual Meat Shredder with Adjustable Interchangeable Bars
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing meat shredding technologies are inefficient, expose operators to contaminants, and do not allow for easy adjustment of meat thickness or aseptic handling.
Innovation Solution
A manual meat shredder with a horizontal rotating cylinder and interchangeable bars, powered by a lever or reduction motor, featuring a hopper with safety covers and electrical controls for safe operation, allowing for adjustable shredding and aseptic handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual meat shredding is used, then the operator can control the shredding process, but the operator is exposed to meat contaminants and the process is time-consuming
Solution Approach 1:
The patent introduces a hopper as an intermediary device that allows meat to be fed into the shredding mechanism without the operator directly contacting the meat. The hopper acts as a mediator between the operator and the meat, enabling indirect handling that reduces contamination exposure while maintaining control over the feeding process.
Solution Approach 2:
The patent replaces manual direct manipulation of meat with a mechanical shredding system consisting of rotating bars and cutting elements. This mechanical system performs the shredding function automatically, reducing the need for operators to directly handle and manipulate meat, thereby minimizing exposure to contaminants.
2Adaptability or versatility
If fixed thickness bars are used, then the shredding structure is simple, but the meat thickness cannot be adjusted
Solution Approach 1:
The patent implements adjustable bar spacing mechanisms that allow the distance between cutting bars to be dynamically changed. This enables the shredding machine to adapt to different meat thickness requirements by modifying the gap between bars, providing versatility while maintaining a relatively simple overall structure through modular adjustment mechanisms.
3Object-affected harmful factors
If safety covers are added to the hopper, then operator safety is improved, but the device complexity increases
Solution Approach 1:
The patent divides the hopper into segmented sections with removable safety covers that can be independently opened or closed. This segmentation allows operators to access specific areas for maintenance or cleaning while maintaining safety coverage over the majority of the shredding mechanism, providing safety protection without requiring a completely complex enclosed structure.

AI summary
A machine for manual action that releases, shreds or defrays the different fibers of meat for human consumption, be it chicken, beef, pork or any other suitable animals that have fibers. These are characterized by having a bar of different shapes located on the periphery of a shaft which has a handle for manual action so that when the operator turns the handle, bars that are located linearly and equidistant on an axis rotate so that the meat pieces located in the tray enter through an opening and collide between the bars inside the casing. The rotating and fixed bars swivel between said bars and rods, allowing the bars to rotate without colliding or crossing. Through this movement, the pieces of meat are shredded or defrayed in different sizes, depending on the distance and speed between the linear bars moving and those that are fixed. Note the system may also work with either reduction gears and or a reduction motor. This shredder may be attached to the table via a vise or similar mechanism.
