Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional frying devices require frequent refilling of oil and pose safety risks due to potential fires during cooking, with existing solutions like hydrogen gas being hazardous and inefficient.
Innovation Solution
A frying device with a metering unit featuring multiple dosing openings and a compressed gas storage system acting as an extinguishing agent, allowing for uniform distribution of roasting agents and efficient fire suppression using CO2 or other gases, reducing structural complexity and enhancing user comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a single dosing opening is used to introduce roasting agent, then the device structure is simple, but the distribution of roasting agent on the frying surface is uneven
Solution Approach 1:
The single dosing opening is segmented into multiple dosing openings (at least three) arranged on the frying pan body. Each opening introduces roasting agent to a different location on the frying surface, achieving uniform distribution across the entire surface rather than concentrating it in one area.
2Reliability
If hydrogen gas is used for pressurized spraying to achieve non-stick function, then the frying surface becomes non-stick, but the device becomes highly explosive and unsafe
Solution Approach 1:
The patent replaces the harmful hydrogen gas (highly explosive) with compressed air or other safe gases. The compressed gas still provides the necessary pressurization for spraying the roasting agent uniformly across the frying surface, achieving the non-stick effect without the explosive hazard.
Solution Approach 2:
The patent uses inert or non-flammable compressed air instead of flammable hydrogen gas to create a safe operating environment. The compressed air serves the same functional purpose of pressurizing and distributing the roasting agent while eliminating the fire and explosion risks associated with hydrogen.
3Ease of operation
If a separate storage bottle is used for introducing frying oil, then the frying oil can be introduced, but the user effort increases due to frequent refilling
Solution Approach 1:
The storage bottle for frying oil is merged with the handle of the frying pan, creating an integrated unit. The dosing openings are also integrated into the pan body, allowing the roasting agent to be distributed automatically during normal handling without requiring separate refilling operations.
Solution Approach 2:
The system is designed to automatically distribute the roasting agent through the multiple dosing openings during normal frying operations. The compressed gas system automatically pressurizes and distributes the oil from the integrated storage, eliminating the need for manual refilling and distribution by the user.
4Device complexity
If the compressed gas storage serves only as extinguishing agent memory, then the fire suppression function is reliable, but the structural effort increases
Solution Approach 1:
The compressed gas storage unit is designed to serve multiple functions: it provides the compressed air for spraying and distributing the roasting agent through the dosing openings, and simultaneously serves as the extinguishing agent memory for fire suppression. This multi-functionality eliminates the need for separate storage components, reducing structural complexity while maintaining reliable fire suppression capability.
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 solution provides a reliable and user-friendly cooking experience by ensuring uniform oil distribution and quick fire suppression, reducing the effort and risk associated with traditional frying methods.
Implementation Method 1
the compressed gas storage is designed as an extinguishing agent memory... the carbon dioxide acted upon by pressure can be used on the one hand for deleting a fire and on the other hand for spraying or nebulizing the roasting agent
Implementation Method 2
the compressed gas storage is designed as an extinguishing agent memory... which can be used to delete a fire in the frying body
