Non-Stick Pan Coating With Edible Oil for Pre-Grease-Free Cooking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing non-stick pots and pans require pre-greasing with edible oil to enhance their non-stick properties, which not all users comply with, leading to reduced cleaning effectiveness, potential flavor and appearance issues, and degradation of the non-stick layer over time.
Innovation Solution
A production method involving multiple layers of non-stick material coating applied to the cooking cavity, with a final layer incorporating edible olive oil, enhancing the non-stick properties without the need for pre-greasing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users grease the PTFE coating before first use, then the non-stick capacity and impermeability are improved, but users may omit this step due to lack of attention or diet-related choices, leading to reduced cleaning effectiveness and degradation of the non-stick layer
Solution Approach 1:
The patent applies preliminary action by incorporating edible oil into the PTFE coating during the manufacturing process before the product reaches the user. The oil is mixed with the PTFE compound and applied in layers during coating formation, so the non-stick properties are pre-established without requiring user intervention. This resolves the contradiction by ensuring reliable non-stick performance while eliminating the operational step that users might omit.
2Reliability
If multiple layers of PTFE coating are applied, then the non-stick properties are improved, but the manufacturing process becomes more complex and time-consuming
Solution Approach 1:
The patent merges the application of PTFE coating and edible oil into a single integrated process. Instead of separately applying multiple PTFE layers and then adding oil, the oil is incorporated into the PTFE compound itself, allowing simultaneous application of both materials in one coating process. This reduces manufacturing complexity while maintaining the multi-layer structure's non-stick benefits.
Solution Approach 2:
The patent creates a composite material by combining PTFE with edible oil within the coating layers. This composite approach allows the coating to exhibit both the non-stick properties of PTFE and the lubricating properties of oil, achieving enhanced performance without requiring separate application steps for each material.
3Reliability
If multiple layers of PTFE coating are applied, then the non-stick properties are improved, but the production time and cost increase
Solution Approach 1:
By incorporating oil during the coating formation process itself, the patent eliminates subsequent separate oiling steps that would extend production time. The preliminary integration of oil into the PTFE layers during manufacturing streamlines the process, maintaining enhanced non-stick properties while improving production efficiency and reducing costs.
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 method ensures the non-stick layer remains effective and durable, improving cleaning efficiency and food flavor while maintaining the appearance of the pot, eliminating the need for pre-greasing.
Implementation Method 1
The purpose of the edible oil is to fill the micro-pores of the layer of PTFE and to increase its non-stick capacity, as well as making it even more impermeable to the foods cooked
Implementation Method 2
forming a coating (3) in multiple layers (4, 5 and 6), which are superposed and applied to the pot (1) one after another
Implementation Method 3
subsequent drying and baking in an oven of the substance applied

AI summary
A method for making pots and pans, equipped with a multi-layer coating of non-stick material including the forming of multiple layers of coating of an inner surface of a wall delimiting a cooking cavity, performed by cyclical repetition of a step of applying suitable substances and subsequent drying and baking in an oven of said layers of substances applied, at least the final layer of said substances being obtained by using a non-stick substance. The method includes, before the step of applying the substance for forming at least the final layer coating the cooking cavity of the pot, a step of adding as an additive edible oil or grease to the liquid substance to be applied for forming said final layer.
