Egg Reorientation Device Using Spreading Rods
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the poultry-farming industry, eggs are often incorrectly positioned in trays, leading to their longitudinal axis being inclined relative to the vertical axis, which complicates handling and treatment operations, as existing tools are inefficient in realigning them effectively.
Innovation Solution
A device with reorientation elements that move between low and high positions, featuring upright rods that spread to interpose between the egg and the tray, guiding the egg to a vertical position using its weight, with flexible or deformable components to facilitate sliding and reduce friction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If vibration mechanism is used to reorient eggs, then eggs may realign along vertical axis, but friction and tray nature prevent effective realignment without guiding
Solution Approach 1:
The patent introduces a guiding element as an intermediary component between the vibration mechanism and the egg. This guiding element has a contour that matches the egg shape, providing a physical guide that directs the egg to the correct vertical orientation while vibration provides the motivating force. The mediator resolves the contradiction by providing the missing guidance function that friction alone cannot achieve.
2Productivity
If eggs are handled in inclined positions during incubation, then incubation processes are optimized, but eggs become misaligned and require realignment before treatment
Solution Approach 1:
The patent applies preliminary action by performing egg realignment immediately before treatment operations. The device quickly reorients misaligned eggs to vertical position using vibration and guiding elements, preparing them in advance for subsequent injection or observation procedures. This preliminary realignment step ensures smooth subsequent operations without requiring manual adjustment during critical treatment moments.
3Manufacturing precision
If manual realignment of eggs is performed, then precise positioning is achieved, but time consumption and labor increase
Solution Approach 1:
The patent implements self-service by designing a system where eggs automatically realign themselves through the combined action of vibration and the guiding element contour. The egg's own weight and the guiding geometry work together to achieve precise vertical positioning without external manual intervention. This eliminates time-consuming manual handling while maintaining high positioning precision.
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 device efficiently reorients eggs to a substantially vertical position, ensuring predictable internal content positioning and optimizing handling operations, such as injection and observation, without requiring tray replacement.
Implementation Method 1
upright rods being intended to interpose themselves between the cell and the egg, in the high position, so as to damp and guide a movement of the egg under the effect of its weight to a substantially vertical position
Implementation Method 2
the upper ends of said rods being able to spread out with respect to each other on contact with the egg to be reorientated
