Porous Egg Poaching Container That Blocks Albumen Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for poaching eggs are impractical and often result in variable quality due to dispersion of egg whites, flavor tainting, and difficulty in removing cooked eggs, especially when using containers with holes that allow albumin to seep through and adhere to the container.
Innovation Solution
A container made from a partially permeable membrane with pores smaller than egg molecules, allowing water to pass while keeping albumen out, and made from heat-sealable paper or infusion webbing for non-stick properties, enabling easy egg removal without oil or vinegar.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a container with holes is used to poach eggs, then water can flow through to cook the egg, but the albumin seeps through the holes and blocks them, preventing further drainage and circulation
Solution Approach 1:
The patent employs a porous membrane material with precisely controlled pore sizes that permit water molecules to pass through while blocking larger albumin molecules. This selective permeability maintains continuous water flow and drainage functionality throughout the cooking process without the blocking issue encountered with conventional hole-based containers.
Solution Approach 2:
The container utilizes a membrane with non-uniform pore distribution or varying pore sizes in different regions, allowing optimal water permeability in areas requiring drainage while preventing albumin leakage in areas where egg containment is critical. This localized property variation resolves the contradiction between water flow and albumin containment.
2Loss of substance
If albumin flows through holes in the container, then drainage is achieved, but the set albumin causes the entire poached egg to adhere to the container, making removal difficult
Solution Approach 1:
The porous membrane's pore size is engineered to be smaller than albumin molecules, completely preventing albumin from entering and adhering to the container. This eliminates the sticking problem entirely while still allowing water to pass through for effective drainage during cooking.
Solution Approach 2:
The porous membrane acts as an intermediary barrier between the egg and the container structure. It mediates the interaction by allowing water passage for drainage while blocking albumin contact with the container, thus preventing adhesion and facilitating easy egg removal.
3Stability of the object's composition
If vinegar is added to boiling water to prevent egg white dispersion, then the egg shape is maintained, but the flavor of the egg is tainted
Solution Approach 1:
The porous membrane container serves as an intermediary structure that physically contains the egg white during the initial cooking phase, preventing dispersion into the boiling water without requiring chemical additives like vinegar. This maintains both egg shape integrity and natural flavor.
Solution Approach 2:
The invention extracts the egg from direct contact with the boiling water environment by placing it within the porous membrane container. This separation allows the egg to cook through water vapor and conducted heat while preventing the chemical interactions that would occur with vinegar addition, thus avoiding flavor tainting.
4Productivity
If multiple eggs are cooked simultaneously, then productivity increases, but proper poaching technique becomes extremely difficult to maintain
Solution Approach 1:
The invention divides the cooking system into individual porous membrane containers, each capable of holding and cooking one egg independently. Multiple such containers can be simultaneously immersed in a single pan of boiling water, allowing unskilled cooks to prepare multiple poached eggs at once while each egg maintains proper poaching conditions within its own container.
Solution Approach 2:
The porous membrane container is designed as a universal cooking device that can accommodate multiple eggs simultaneously. Each container performs the complete poaching function independently, transforming a skill-intensive individual egg poaching process into a scalable multi-egg operation suitable for professional kitchens.
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
Enables the production of perfectly shaped, untainted poached eggs with no dispersion, allowing multiple eggs to be cooked simultaneously and facilitating easy removal without oil or vinegar, suitable for both skilled and unskilled cooks.
Implementation Method 1
the container is water permeable, and is impermeable to liquids of the density of raw albumen and raw vittelus
Implementation Method 2
the container comprises a first sheet and a second sheet and wherein the two sheets are sealed to each other about their respective peripheral areas
Implementation Method 3
when the container is immersed in a water source and wetted, the open ends of the container tend to adhere gently to each other due to surface tension
