Poultry Scraper Head With Recessed Jacket For Neck Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tools for cleaning the neck of poultry carcasses often cause damage to the skin and bones and remove unnecessary tissue from the neck vertebrae during the removal of the windpipe, gullet, and crop.
Innovation Solution
A scraper head with an elongate scraping body featuring a jacket with recesses and a coupling segment, where the recesses have a complex geometry with parallel branches and a rounded corner transition, allowing for efficient detachment of tissue parts while minimizing damage to the carcass, and a central passage for suction or fluid application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing tools are used to remove windpipe, gullet and crop, then these tissue parts are removed, but damage is frequently caused to the skin and bones of the neck
Solution Approach 1:
The scraper head features a jacket with recesses that create localized scraping edges only in specific areas where tissue removal is needed. This localizes the scraping action to precise locations, allowing effective removal of windpipe, gullet and crop while protecting the surrounding skin and bones from damage.
Solution Approach 2:
The scraping body is divided into multiple recesses with scraping edges distributed along its length. This segmentation allows the tool to remove tissue parts in controlled sections rather than applying uniform scraping force throughout, thereby removing necessary tissue while preserving intact skin and bone structures.
2Productivity
If existing tools are used for neck cleaning, then tissue parts are removed, but unnecessary tissue is removed from the neck vertebrae
Solution Approach 1:
The recesses in the jacket are positioned and shaped to target specific tissue parts (windpipe, gullet, crop) while avoiding contact with the neck vertebrae. The scraping edges are localized to areas where tissue removal is necessary, preventing unnecessary removal of vertebraal tissue.
Solution Approach 2:
The design extracts only the necessary tissue parts through the recesses while leaving the neck vertebrae intact. The scraping action is confined to the recessed areas, effectively separating the removal function from the preservation function in a single tool design.
3Manufacturing precision
If a scraper head with complex recess geometry is used, then precise tissue removal is achieved, but the device complexity increases
Solution Approach 1:
The complex scraping function is achieved through segmentation into multiple recesses with scraping edges. Each recess is a simpler geometric element that can be manufactured independently, and their collective arrangement provides the precise tissue removal capability without requiring a single complex monolithic structure.
