Solution Overview

Problem

Existing automatic breast fillet extraction devices for poultry carcasses often fail to reliably differentiate between completely and incompletely filleted carcasses, necessitating costly manual inspection and intervention.

Innovation Solution

A device equipped with a measuring system that automatically detects the angular position of a sensing element to determine if the breast fillet is fully removed, using a pivotable feeler element and inductive sensor to assess the filleting success, allowing for the differentiation between filleted and unfilleted carcasses and enabling automatic ejection of incompletely processed ones.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual inspection is used to verify filleting completeness, then detection reliability is improved, but labor costs and processing time increase

Engineering Contradiction:
Improvefilleting assessment reliabilityVSAvoidprocessing efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent replaces manual visual inspection with an automated mechanical sensing system. A probe element with force-sensitive resistor scans the breast side of the poultry carcass, mechanically detecting the presence or absence of breast fillet through contact sensing, thereby eliminating the need for manual inspection while maintaining detection reliability

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables self-inspection by the processing machine itself. The sensing element automatically scans each carcass and provides feedback to the control device, which then directs the ejection device to remove incompletely filleted carcasses, allowing the system to monitor and correct its own performance without external human intervention

Inventive Principle:
Principle #25Self-service

2Measurement precision

If complex sensing systems are used to detect filleting completeness, then measurement precision is improved, but device complexity increases

Engineering Contradiction:
Improvefilleting detection precisionVSAvoidsensing system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent extracts only the essential sensing function needed for filleting detection. Instead of using complex multi-sensor systems, it employs a single probe element with a force-sensitive resistor that measures only the presence or absence of breast fillet through simple contact force detection, achieving sufficient precision with minimal complexity

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system changes the measurement parameter from complex visual or dimensional analysis to simple contact force measurement. The force-sensitive resistor detects changes in force when the probe contacts the breast fillet, converting a complex quality assessment into a simple physical parameter measurement that is easy to detect and evaluate

Inventive Principle:
Principle #35Parameter changes

3Extent of automation

If mechanical scanning systems are used to inspect poultry carcasses, then automation level is improved, but hygiene maintenance difficulty increases

Engineering Contradiction:
Improveinspection automation levelVSAvoidcleaning ease
Core Design Contradiction:
Extent of automationVSEase of manufacture

Solution Approach 1:

The probe element is designed as a slender, simple mechanical structure that can be easily cleaned. The force-sensitive resistor is positioned at the tip of the probe, allowing the entire sensing element to be quickly rinsed and sanitized, meeting hygiene requirements while maintaining automation

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The sensing element is designed to be simple and replaceable. If contamination occurs, the entire probe assembly can be quickly replaced rather than requiring complex disassembly and cleaning procedures, effectively treating the sensing element as a disposable or easily renewed component to maintain hygiene standards

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)
