Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional suction-type egg lifting devices in poultry hatcheries require additional mechanisms and power, are difficult to maintain, and cannot straighten eggs oriented at an angle, posing challenges in egg processing and transfer.
Innovation Solution
A vacuum-less/suction-less egg lifting device using physical engagement with shape-memory materials and resilient members to securely lift and transfer eggs, capable of straightening off-axis eggs without mechanical actuation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If suction-type lifting devices are used to lift eggs, then eggs can be lifted and transferred, but additional mechanisms and power requirements are needed
Solution Approach 1:
The patent extracts and eliminates the vacuum system from the egg lifting device, replacing it with a passive mechanical engagement mechanism. The lifting device now uses a simple cup-shaped structure that engages with the egg through gravity and mechanical contact, removing the need for complex vacuum generation equipment and power consumption.
Solution Approach 2:
The patent replaces the pneumatic vacuum system with a purely mechanical engagement system. The cup-shaped lifting surface engages the egg through direct mechanical contact, using the weight of the egg and controlled release mechanisms rather than suction forces, thereby eliminating the need for motors, vacuum pumps, and associated power requirements.
2Reliability
If suction-type lifting devices are used to lift eggs, then eggs can be lifted and transferred, but the devices are difficult to maintain and clean
Solution Approach 1:
The patent removes the vacuum system components (motors, seals, hoses, filters) that made maintenance difficult, leaving only a simple cup-shaped structure and release mechanism. This dramatically reduces the number of parts that require maintenance and cleaning, making the device much easier to service.
Solution Approach 2:
The patent employs a porous or perforated cup structure that allows debris and contaminants to pass through rather than accumulating on surfaces. This self-cleaning effect reduces maintenance requirements by preventing build-up of egg residue and bacterial contamination on the lifting surfaces.
3Productivity
If polymer-based suction cups are used continuously, then eggs can be lifted, but the cups become deformed about the lip area affecting suction ability
Solution Approach 1:
The patent employs a simple, inexpensive cup-shaped structure made from durable but replaceable materials. Rather than relying on expensive polymer suction cups that deform over time, the design uses a robust mechanical structure that can be easily replaced if worn, maintaining consistent performance throughout its service life.
Solution Approach 2:
The patent utilizes composite material construction for the cup structure, combining materials with different properties to maintain structural integrity and shape stability. The composite construction resists deformation at the lip area while maintaining the necessary flexibility for egg engagement, solving the deformation problem of continuous use.
4Reliability
If suction-type lifting devices are used, then eggs can be lifted, but eggs oriented at an angle cannot be straightened
Solution Approach 1:
The patent employs a dynamic release mechanism that allows the cup to engage eggs in various orientations and then actively straighten them through controlled movement. The release mechanism can adjust the cup's position and angle, enabling the device to handle eggs whether they are horizontal, vertical, or at intermediate angles, and actively orient them correctly during the lifting process.

AI summary
An egg transfer system (600) is provided. Such a system includes a first securing arrangement (550) configured to engage and deflect about an egg (1) such that the egg is capable of being seated within the first securing arrangement. A second securing arrangement (550) is opposingly positioned with respect to the first securing arrangement, the second securing arrangement being configured to engage and deflect about an egg (1) such that the egg is capable of being seated within the second securing arrangement. The first and second securing arrangements (550) are configured to interact through relative movement with respect to one another, such interaction thereby causing an egg to be transferred therebetween. Associated systems and methods are also provided.
