Solution Overview

Problem

Current methods for controlling and standardizing bird weights in poultry farms require manual or mechanical intervention, causing stress, injuries, and significant labor, with existing equipment failing to meet the need for autonomous weight-based division and sorting without human interaction.

Innovation Solution

The implementation of autonomous standardization scales within aviaries that automatically adjust bird divisions based on weight, using actuators to transfer birds between compartments, eliminating the need for manual handling and reducing the risk of injury and stress.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual weighing and sorting methods are used, then weight control accuracy is improved, but labor requirements and operational complexity increase significantly

Engineering Contradiction:
Improveweight control accuracyVSAvoidoperational complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system enables birds to perform self-weighing by walking through the scale structure, eliminating the need for manual handling. The automatic weight detection and real-time data transmission to the central system allows the birds to be sorted autonomously based on their weight, resolving the contradiction between measurement precision and operational complexity.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical weighing and sorting operations with an automated electronic system. Load cells detect bird weight automatically, and the central system processes this data to control feed distribution, substituting human labor with an integrated electronic control system that maintains accuracy while reducing operational complexity.

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

2Productivity

If mechanical weighing equipment is used, then labor requirements are reduced, but bird stress and injury risk increase

Engineering Contradiction:
Improvelabor efficiencyVSAvoidbird stress and injury
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

Birds voluntarily walk through the weighing structure to access feed, performing the weighing action themselves without being handled by machinery. This self-service approach eliminates the harmful mechanical constraints and stress associated with traditional mechanical weighing equipment while maintaining productivity through automated weight detection and feed control.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system introduces an intermediary electronic detection system (load cells and sensors) that measures bird weight without physical contact or mechanical constraint. This intermediary approach allows accurate weight measurement and automated feed allocation without the bird stress and injury caused by direct mechanical handling.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Stability of the object's composition

If frequent weighing and sorting is performed, then weight uniformity within divisions is improved, but production time and operational costs increase

Engineering Contradiction:
Improveweight uniformityVSAvoidproduction time
Core Design Contradiction:
Stability of the object's compositionVSLoss of time

Solution Approach 1:

The system implements continuous weight monitoring and automatic feed adjustment rather than periodic batch weighing and sorting. Birds are weighed continuously as they move through the system, and feed allocation is adjusted in real-time based on individual weight data, maintaining weight uniformity without interrupting production flow or consuming additional time.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The system uses real-time feedback from weight sensors to automatically adjust feed distribution to each bird based on its current weight status. This continuous feedback loop maintains optimal weight uniformity within divisions without requiring time-consuming manual intervention or repeated sorting operations, as the system proactively prevents weight deviations rather than correcting them later.

Inventive Principle:
Principle #23Feedback

AI summary

The request for privilege of invention is directed to the poultry sector and deals with divisions and scales implanted in breeding farms of matrices with the objective of uniting the birds provided with similar weights within a single division without exceeding the maximum number of birds stipulated in that space. The aviary (1) is divided into three parts or divisions (2), (3) and (4) using barriers (5) and (5'), the first division (2) being aimed at lighter birds, the second (3) at medium weight birds and the third division (4) suitable for heavy birds. Next to the barriers (5) and (5'), the scales (6) are inserted in the form of cages that act as passages between the divisions of the aviary. The system created specifically to control the scales regulates the inflow and outflow within a total maximum number at each division, i.e., where a maximum number of birds per division was determined, no scale will remain with the trapdoor open in the inflow to that division, only in the outflow direction, until the maximum number of birds is normalized.
