Solution Overview

Problem

Existing poultry farming systems fail to effectively enhance the health and welfare of poultry through adequate movement encouragement, leading to suboptimal productivity and feed conversion ratios.

Innovation Solution

A lighting system that projects narrow beam divergence light beams, controlled by a system responsive to poultry properties, adjusts characteristics such as speed, color, and pattern to stimulate movement and habituation prevention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If conventional lighting systems are used in poultry farming, then the system structure is simple, but the poultry movement is insufficient and welfare is not improved

Engineering Contradiction:
Improvepoultry movement and welfareVSAvoidlighting system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The lighting system dynamically adjusts light beam characteristics (position, color, intensity, pattern) in real-time based on poultry behavior feedback. The control system modifies lighting parameters adaptively to stimulate natural movements and prevent habituation, transforming a static lighting system into a dynamic one that actively responds to poultry needs.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system incorporates sensors to detect poultry movement and behavior, feeding this information back to the control system which then adjusts lighting parameters accordingly. This closed-loop feedback mechanism enables the lighting system to adapt to poultry responses, optimizing welfare outcomes while maintaining manageable system complexity.

Inventive Principle:
Principle #23Feedback

2Productivity

If static lighting characteristics are used, then the system is easy to control, but poultry becomes habituated and movement stimulation decreases

Engineering Contradiction:
Improvepoultry movement stimulationVSAvoidlighting control complexity
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The lighting system implements periodic variations in light beam characteristics including pulsing patterns, rhythmic movements, and cyclic color changes. These periodic actions stimulate poultry movements by preventing habituation, as the predictable yet varying patterns engage poultry instinctively while remaining systematically controllable.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system continuously varies multiple lighting parameters simultaneously including position, color temperature, intensity, and beam patterns. By changing multiple parameters in coordinated fashion, the system maintains poultry interest and stimulation effectiveness without requiring overly complex control logic, as parameter interrelationships provide structured control opportunities.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If broad beam divergence lighting is used, then the lighting coverage is wide, but the light spot is diffuse and less effective at stimulating movement

Engineering Contradiction:
Improvemovement stimulation effectivenessVSAvoidlight spot concentration
Core Design Contradiction:
ProductivityVSArea of stationary object

Solution Approach 1:

The system uses narrow beam divergence to create highly concentrated light spots at specific locations within the poultry housing. This local quality approach focuses illumination intensity on precise points to maximize movement stimulation effectiveness, while the control system moves these concentrated spots across different areas to provide both intensity and coverage.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The lighting system dynamically positions narrow beam light spots across different areas of the housing, creating concentrated illumination zones that move and change over time. This dynamic positioning allows the system to maintain high local intensity for effective stimulation while providing broad area coverage through temporal distribution of the concentrated beams.

Inventive Principle:
Principle #15Dynamics

4Adaptability or versatility

If lighting characteristics are not adapted to poultry properties, then the system is simple to operate, but the response to poultry needs is suboptimal

Engineering Contradiction:
Improveresponse to poultry propertiesVSAvoidcontrol system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The control system adapts lighting parameters including color temperature, intensity, and beam patterns based on detected poultry properties such as age, species, and behavior patterns. By systematically adjusting parameters in response to measured poultry characteristics, the system achieves high adaptability while maintaining structured control through parameter-based adaptation rules.

Inventive Principle:
Principle #35Parameter changes
