Solution Overview

Problem

Existing carcass cutting systems face issues such as operational downtimes due to frequent cleaning needs, higher maintenance costs, increased weight, and complexity from multiple tools, leading to slower operation and higher operational expenses.

Innovation Solution

A system with a support assembly and retractable cutting tools that allow independent movement along different paths to process carcass portions, featuring separate cleaning tools for each cutting tool to minimize downtime and maintenance, and a blade guard for improved cutting efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple cutting tools are used to process different carcass portions, then cutting functionality is improved, but device complexity and weight increase

Engineering Contradiction:
Improvecutting functionalityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cutting system is divided into multiple independent cutting tools (first cutting tool and second cutting tool) that can be selectively positioned and operated. Each tool is mounted on the support assembly at different locations, allowing independent operation for different carcass portions without increasing overall system complexity

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If multiple cutting tools are used to process different carcass portions, then cutting functionality is improved, but weight increases

Engineering Contradiction:
Improvecutting functionalityVSAvoidweight
Core Design Contradiction:
Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The support assembly is designed with distributed mounting points for multiple cutting tools, allowing each tool to be positioned at optimal locations for different carcass portions while maintaining balanced weight distribution across the support structure

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The retractable assembly enables dynamic positioning of cutting tools, allowing the system to adjust tool positions and configurations based on the specific cutting task, optimizing weight distribution and operational efficiency

Inventive Principle:
Principle #15Dynamics

3Reliability

If cleaning is performed after each cutting operation, then reliability is improved, but loss of time increases

Engineering Contradiction:
Improvecleaning reliabilityVSAvoidcleaning time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The cleaning tools are positioned and ready for immediate use after cutting operations. The retractable assembly allows cleaning tools to be pre-positioned at cleaning locations, enabling rapid cleaning without significant time loss between cutting operations

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system enables continuous operation by allowing cleaning to be performed during or immediately after cutting operations without significant interruption. The retractable mechanism allows seamless transition between cutting and cleaning modes, maintaining continuous productive action

Inventive Principle:
Principle #20Continuity of useful action

4Productivity

If cleaning tools are positioned close to cutting tools, then cleaning efficiency is improved, but safety risks increase

Engineering Contradiction:
Improvecleaning efficiencyVSAvoidsafety risks
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The retractable assembly enables dynamic positioning of cleaning tools, allowing them to be retracted away from cutting tools during cutting operations to eliminate safety hazards, and then extended to cleaning positions when cutting is complete, maintaining both safety and cleaning efficiency

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The support assembly is designed with separate mounting mechanisms for cutting tools and cleaning tools, allowing independent positioning and retraction of each tool type. This segmentation enables cleaning tools to be positioned close to cutting tools for efficient cleaning, while maintaining safety through independent control and retraction capabilities

Inventive Principle:
Principle #1Segmentation

AI summary

A system and method for cutting a carcass. The system comprises a support assembly (12) movable along a first path and a second path adjacent to a first portion and a second portion of the carcass respectively; a retractable assembly (14) movable between an extended configuration when the support assembly is moved along the first path and a retracted configuration away from the carcass when the support assembly (12) is being moved along the second path; a first cutting tools (16) processing the first portion of the carcass when the support assembly (12) is moved along the first path, and disengaging from the carcass when the retractable assembly (14) is in the retracted position; and a second cutting tool processing the second portion of the carcass when the support assembly (12) is moved along the second path. The first cutting tool (16) is independently and separately movable relatively to movement of the second cutting tool (18).
