Transporting element for accommodating and transporting eggs, and cooking appliance, pasteurizer or cooling unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transport elements for eggs in cooking, pasteurizing, or cooling devices do not effectively wet the entire surface of spherical or egg-shaped objects, particularly during pasteurization, as they are designed to minimize eggshell contact with fixation elements, limiting the area that can be sprayed with heated water.
Innovation Solution
A channel-shaped transport element with curved, part-circular recesses that pivot 180°, allowing the entire egg surface to be wetted by heated water, featuring slit-shaped recesses and longitudinal webs for stability and mounting elements for pivotable attachment along a conveyor path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the transport element uses fixation elements to hold eggs, then the eggs are securely positioned during transport, but the eggshell surface area available for spraying with heated water is reduced
Solution Approach 1:
The transport element is designed to pivot 180° between uphill and downhill sections of the meandering conveyance path. This dynamic movement causes eggs to roll within the recesses, changing their orientation and exposing different surface areas to spray nozzles at different positions along the path, thereby increasing the overall sprayable surface area while maintaining secure positioning through the curved recess geometry
Solution Approach 2:
The transport element divides the eggholding function into multiple segments along the meandering path, with each recess positioned to exploit different gravitational orientations. This segmentation allows different portions of the egg surface to be exposed to spray at different locations, effectively increasing total sprayable area while maintaining reliable egg holding at each segment
2Duration of action of moving object
If the conveyance path is designed to be meandering to allow sufficient treatment time, then eggs receive adequate pasteurization, but the device becomes larger and more complex
Solution Approach 1:
The meandering path is designed with uphill and downhill sections that utilize gravitational potential energy. Eggs are passively accelerated downhill and decelerated uphill, creating natural speed variations that extend the residence time in the pasteurization chamber without requiring additional mechanical speed control mechanisms, thereby achieving adequate treatment time with simpler device architecture
3Area of stationary object
If the transport element pivots 180° through meandering sections, then the entire egg surface can be wetted with heated water, but the egg may become unstable during pivoting
Solution Approach 1:
The recesses are designed with curved, arc-shaped bottoms that conform to the spherical geometry of eggs. This curvature creates a natural rolling path for eggs during pivoting, ensuring they remain centered and stable within the recesses while still being able to rotate sufficiently to expose their entire surface to spray, thereby maintaining stability during the dynamic pivoting motion
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
Ensures even treatment of eggs by allowing the entire surface to be sprayed with heated water during transport, maintaining egg stability and allowing for efficient use of compact device designs.
Implementation Method 1
the transport route is designed in a meandering manner around the horizontally covered conveying path in order, due to gravity, to be able to pivot the transport element by 180° from a first position, for example in an uphill section of the transport section, into a second position in a downhill section of the transport section
