Solution Overview

Problem

Existing equipment for shredding meat products fails to produce a consistently sized, hand-pulled-like product that meets industry standards for pizza toppings and whole muscle meats, lacking the desired engagement and separation action.

Innovation Solution

A circular shredder blade with a 16-point star shape and angled teeth, allowing for consistent separation and shredding, featuring a forward angled rake and leading point for improved engagement and pulling action, and adjustable blade configurations for varying food textures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If conventional star attachment cutting/shredding blades are used, then the shredding function is provided, but the product appearance does not resemble hand-pulled meat and consistency is poor

Engineering Contradiction:

Improveproduct consistencyVSAvoidproduct appearance

Core Design Contradiction:

Manufacturing precisionVSShape

Solution Approach 1:

The patent modifies the geometric parameters of the blade teeth, specifically the rake angle and tooth shape, to change the cutting mechanism from a conventional shredding action to a pulling action that mimics hand-pulled meat appearance while maintaining consistent product size

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The blade design incorporates varying rake angles on different portions of the teeth, with the leading edge having a specific rake angle to initiate the pull and the trailing edge having a different angle to complete the separation, creating localized functional zones that achieve both appearance and consistency goals

Inventive Principle:

Principle #3Local quality

2Ease of operation

If the blade speed, angle, and width are increased to improve separation action, then the engagement and pulling action is enhanced, but the device complexity and adjustment requirements increase

Engineering Contradiction:

Improveengagement actionVSAvoidblade configuration

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent makes the blade system adjustable by allowing changes in blade speed, angle, and width parameters, transforming a static blade design into a dynamic system that can be optimized for different food products while maintaining ease of operation through standardized adjustment mechanisms

Inventive Principle:

Principle #15Dynamics

3Productivity

If the rake area has a varying angle to increase aggressiveness of engagement, then the pulling action is improved, but the manufacturing precision requirements increase

Engineering Contradiction:

Improvepulling action efficiencyVSAvoidrake angle consistency

Core Design Contradiction:

ProductivityVSManufacturing precision

Solution Approach 1:

The blade design incorporates a leading point or leading edge that makes initial engagement with the product before the main rake area, preliminarily initiating the separation action and reducing the precision requirements for the varying rake angles while maintaining effective pulling action

Inventive Principle:

Principle #10Preliminary action

AI summary

An apparatus a circular blade device to produce consistent separated portions of a product to produce a severed portion, pulled and/or shredded product from cooked meat items or other food products as well as a more consistent sized crumble with precooked sausage based items. One embodiment can include a 16 point star shape with angled head or teeth to allow for the pulling of a consistent size product.
