Waveform Light Trap Panels for Poultry House Airflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light traps for poultry houses face a trade-off between resistance to light transmission and airflow, where increasing resistance to light often results in higher airflow resistance, compromising either aspect.
Innovation Solution
The use of light deflective walls (LDWs) on panels of the light traps, which are designed to increase light reduction while maintaining comparable airflow resistance, achieved through specific waveform designs, panel spacing, and light deflective wall shapes, heights, and orientations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If right angle panels are used to block light, then light transmission is reduced, but airflow resistance increases
Solution Approach 1:
The patent applies curvature by using waveform panels with sinusoidal, triangular, or square wave patterns instead of flat panels. These curved/waved surfaces deflect light more effectively while maintaining airflow channels that reduce resistance to air passage through the trap structure.
Solution Approach 2:
The invention introduces light deflective walls extending from the panels into the trap interior space, adding a third dimensional element. These walls create multiple light deflection surfaces and airflow pathways, allowing light blocking in one dimension while preserving airflow in another dimension.
2Illumination intensity
If more panels are added to increase light blocking, then light reduction improves, but device complexity and airflow resistance worsen
Solution Approach 1:
The waveform panels serve multiple functions simultaneously: they block light through their curved surfaces, maintain structural integrity, and create airflow channels. The light deflective walls also perform dual functions of light deflection and airflow guidance, reducing the need for additional separate components.
Solution Approach 2:
The patent combines light blocking and airflow functions into a single integrated panel structure with waveform patterns and attached deflective walls, rather than using separate components. This merging reduces overall device complexity while achieving both light reduction and maintained airflow.

AI summary
Light traps, and panels for light traps, are shown and described. In one example, a trap comprises a plurality of panels defining waveforms for at least a portion. The waveforms may be spaced a distance D apart to define a plurality of non-linear air-passages for allowing an airflow (AF) into or out of the poultry house at a velocity (V). The waveforms may include a plurality of light deflective walls (LDWs) for increasing the light reduction factor (RFL).
