Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cooking devices using refractory cooking stones for dough foods face inefficiencies in cooking due to dirt accumulation, leading to undercooking or overcooking, and require frequent cleaning, which complicates the cooking process and raises hygiene concerns.
Innovation Solution
A cooking device with a refractory cooking stone that is heated by a heater, a washing system with a reservoir for water accumulation and filtration, and a fan to prevent water accumulation on the stone, along with a conductivity sensor and control unit for optimized water usage, ensuring efficient cooking and cleaning while enhancing user safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a refractory cooking stone is used for cooking dough foods, then heat retention and homogeneous cooking are improved, but dirt accumulation on the surface occurs leading to cooking inefficiency and frequent cleaning requirements
Solution Approach 1:
The cooking stone is designed as a removable, separable component from the cooking chamber base, allowing it to be easily detached for cleaning or replacement without disassembling the entire oven structure. This segmentation enables frequent maintenance while preserving the thermal benefits of the refractory material.
Solution Approach 2:
The system incorporates an automated washing mechanism with water nozzles that spray the cooking stone surface during or after the cooking cycle, enabling self-cleaning functionality. This reduces manual intervention and maintains hygiene without requiring user拆卸 of components.
2Ease of operation
If a washing system with spraying members is used to clean the cooking chamber, then cleaning capability is improved, but water accumulation on the cooking stone creates hygiene problems
Solution Approach 1:
The cooking stone surface is designed with a tilted angle rather than being completely flat, creating dynamic water runoff characteristics. This inclination causes water to naturally drain off the stone surface during and after washing, preventing accumulation and associated hygiene issues while maintaining effective cleaning coverage.
Solution Approach 2:
The solution introduces a drainage dimension by positioning water collection channels or reservoirs beneath the cooking stone level. Water is directed downward into collection areas where it can be evaporated or disposed of, adding a vertical drainage dimension to the otherwise horizontal washing process.
3Object-affected harmful factors
If the cooking stone is made smaller than the cooking chamber base, then water drainage and hygiene are improved, but cooking surface area is reduced
Solution Approach 1:
The cooking stone is positioned centrally on the cooking chamber base with a smaller footprint, creating localized high-quality cooking zones where heat concentration is optimal for dough foods. The surrounding base area serves auxiliary functions such as water drainage and heat distribution, allowing the cooking stone to be smaller while maintaining overall system effectiveness.
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 device provides homogeneous cooking, easy cleaning, and improved hygiene by using a high-thermal-capacity cooking stone with a filtration system and fan-assisted water management, reducing the risk of undercooking or overcooking and enhancing user safety through efficient water usage.
Implementation Method 1
The cooking stone is heated by means of the heater provided thereunder
Implementation Method 2
the cooking stone is produced from a material with high thermal capacity. Thus, the cooking stone has high heat retention
Implementation Method 3
The cooking process is performed by dissipating the hot air into the cooking device
Implementation Method 4
By means of the filter, the water delivered from the reservoir is filtered. Thus, the water is cleansed of oil and dirt
Implementation Method 5
The base has an inclined structure so as to guide the water towards the filter. Thus, the water is guided towards the filter without waiting on the base
