Eggshell Extraction Basket with Apertures for Sanitary Shell Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for removing eggshells from raw egg yolks in a pan are inefficient and often result in shell fragments being left behind, leading to contamination and aesthetic issues, especially when handling large quantities of eggs.
Innovation Solution
A handheld egg fragment extraction implement with an elongated upper working arm and a lower working arm, featuring a concave basket with ovoid apertures, designed to scoop shell fragments from egg material while allowing egg whites and yolks to pass through, thereby efficiently removing shells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hands or other utensils are used to extract shells from cracked egg yolks, then shell removal can be performed, but contamination of food products increases and sanitary conditions deteriorate
Solution Approach 1:
The implement extracts the harmful element (eggshell fragments) from the food product by using a basket-like structure with apertures that physically separates shells from egg material through a scooping motion, eliminating direct contact between hands/utensils and food
Solution Approach 2:
The implement acts as an intermediary tool between the operator and the food product, with the basket structure serving as a mediator that allows shell removal while maintaining sanitary conditions through its design that prevents direct contamination
2Ease of operation
If hands or other utensils are used to extract shells from cracked egg yolks, then shell removal can be performed, but aesthetic quality of food presentation deteriorates due to broken yolks
Solution Approach 1:
The implement extracts only the shell fragments from the egg material without disturbing the yolk structure, allowing intact yolks to remain in the food product for better aesthetic presentation
3Productivity
If traditional methods are used to crack and remove eggshells, then egg processing can be completed, but time consumption increases especially when handling large quantities of eggs
Solution Approach 1:
The implement enables continuous shell removal operation where the basket can be repeatedly scooped through egg material to extract shells without interrupting the cooking process, significantly reducing total time for handling large quantities of eggs
4Reliability
If the concave basket has small apertures to retain shell fragments, then shell separation improves, but egg material may be retained along with shells
Solution Approach 1:
The basket structure has non-uniform aperture distribution with varying sizes optimized for different functions: smaller apertures in certain areas to retain shell fragments while larger apertures in other areas allow egg material to pass through freely
