Poultry Transport Cage Door Assembly Vibration Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern chicken processing plants face significant challenges in minimizing untimely bird death during transportation due to the harsh conditions caused by crudely constructed live haul cages with loud and jarring door mechanisms, leading to stress and mortality among poultry.
Innovation Solution
A door assembly for poultry transport cages featuring a frame with a door mounting system that biases the door to remain closed and allows controlled opening, reducing noise and vibration through the use of elongated arms with springs and anti-vibration materials, ensuring smooth operation and preventing unintentional opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If crudely constructed door mechanisms are used in live haul cages, then the door can be opened and closed easily, but noise and vibration increase causing stress and mortality among poultry
Solution Approach 1:
The patent applies beforehand cushioning by incorporating vibration-dampening materials and noise-reducing elements into the door assembly construction prior to operation. The door is pre-equipped with materials that absorb and dampen vibrations and noises during opening and closing operations, preventing harmful factors from affecting the poultry rather than addressing them after the fact.
2Productivity
If spring-loaded doors are used to facilitate loading and unloading, then operational efficiency increases, but the doors become loud and jarring when opening and closing
Solution Approach 1:
The patent introduces intermediary elements between the spring-loaded door mechanism and the surrounding environment. These intermediaries include vibration-dampening materials, noise-absorbing structures, and cushioning elements that mediate the force transmission during door operation, reducing the harmful noise and vibration generated while maintaining the operational efficiency of the spring-loaded mechanism.
3Productivity
If door mechanisms are designed for rapid opening and closing, then throughput increases, but unintentional opening may occur during transport
Solution Approach 1:
The patent applies preliminary anti-action by incorporating features that prevent unintentional door opening during transport. This includes latch mechanisms, locking features, or structural design elements that actively counteract forces that might cause the door to open inadvertently, while still allowing rapid intentional opening when needed for loading and unloading operations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution significantly reduces noise and vibration during transport, minimizing stress and mortality among poultry by maintaining a controlled door movement and preventing premature death, while maintaining the strength to hold birds in place.
Implementation Method 1
the door mounting assembly being configured to bias the door in the closed position to prevent unintentional opening and enable movement of the door between the open condition and the closed condition within a preset range of velocity with limited noise and vibration
Implementation Method 2
reducing noise and vibration through the use of elongated arms with springs and anti-vibration materials
