Solution Overview
Problem
Existing heating and cooking apparatuses, such as ovens and microwave ovens, suffer from lingering odors from cooked foods that persist and permeate into subsequent dishes, causing unpleasant experiences.
Innovation Solution
A heating and cooking apparatus featuring a porous oxide layer formed through anodizing on its surface, combined with a catalyst layer submerged in a catalyst mother liquid, which decomposes odor-causing molecules via a catalyst reaction at temperatures between 200 to 250 °C, enhancing odor removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a conventional smooth surface is used in the heating and cooking apparatus, then it is easy to clean and manufacture, but odors from cooking objects remain and permeate into other foods
Solution Approach 1:
The patent applies a porous oxide layer formed through anodizing reaction on the inner surface of the heating and cooking apparatus. This porous structure provides increased surface area for odor decomposition while the anodized layer itself is durable and easy to maintain, resolving the contradiction between ease of manufacture and odor retention prevention
Solution Approach 2:
The patent creates a composite structure consisting of a metal substrate with an anodized oxide layer and a catalyst layer. This composite material combines the mechanical strength of metal with the odor-decomposing properties of the catalyst, effectively preventing odor retention while remaining manufacturable
2Object-generated harmful factors
If the catalyst layer surface area is increased to improve odor decomposition, then odor removal effectiveness is enhanced, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The porous oxide layer provides a naturally high surface area-to-volume ratio, allowing the catalyst to be distributed over a large surface area without adding significant device complexity. The porosity is inherent to the anodizing process rather than requiring additional structural elements
Solution Approach 2:
The anodizing process itself creates the porous structure that enhances catalyst surface area. The system uses the existing cavity structure and applies a surface treatment that automatically generates the high surface area needed, rather than requiring separate complexity-inducing components
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
Effectively decomposes odor-causing molecules and contaminants, maintaining a sanitary environment by ensuring the catalyst layer has a large surface area and optimal temperature conditions, thereby reducing lingering food odors.
Implementation Method 1
a porous oxide layer formed on at least a portion of a surface of the cavity through an anodizing reaction
Implementation Method 2
odor-causing molecules generated from the cooking object cause a catalyst reaction on the catalyst layer to be decomposed
