Induction Cooktop Pad System for Scratch and Heat Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Induction stoves face issues with ceramic glass cook-top scratches, cracking from heavy vessels, residual heat causing safety hazards, and inefficient cleaning, particularly in multi-stove settings like hotels or dormitories.
Innovation Solution
A cook-top assembly with a pad system that fits within recesses on the cook-top, made of flexible, shock-absorbing materials like silicone rubber, which reduces heat transfer, prevents horizontal movement, and is easily removable for cleaning, while maintaining the induction stove's efficiency and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a smooth ceramic glass cook-top surface is used, then ease of cleaning and appearance are improved, but susceptibility to scratches from cooking vessels increases
Solution Approach 1:
A protective pad made of flexible, shock-absorbing material is introduced as an intermediary layer between the cooking vessel and the ceramic glass cook-top surface. This pad prevents direct contact between potentially damaging vessel surfaces and the cook-top, thereby preventing scratches while maintaining the smooth, easy-to-clean surface properties.
Solution Approach 2:
The protective pad is placed on the cook-top before the cooking vessel is positioned, providing beforehand cushioning and protection. The pad absorbs shocks and prevents impact damage from heavy or dropped vessels, and prevents scratches from rough vessel surfaces before contact occurs.
2Adaptability or versatility
If heavy cooking vessels are used for induction cooking, then cooking capability is improved, but risk of cracking or breaking the cook-top increases
Solution Approach 1:
The flexible, shock-absorbing pad is placed on the cook-top before heavy cooking vessels are positioned, providing beforehand cushioning. The pad absorbs impact forces from heavy vessels and prevents direct transmission of shock loads to the ceramic glass cook-top, thereby preventing cracking while allowing the use of heavy vessels for cooking.
3Ease of manufacture
If the cook-top is made smooth and flat, then appearance and ease of cleaning are improved, but heat transfer from cooking vessels to the cook-top surface increases
Solution Approach 1:
The protective pad serves as a thermal intermediary layer between the cooking vessel and the cook-top surface. It allows controlled heat transfer during cooking while preventing excessive heat buildup on the cook-top surface, thereby reducing residual heat hazards while maintaining the smooth, flat cook-top design.
4Ease of manufacture
If cleaning products are used on the cook-top, then cleanliness is improved, but damage from abrasive products increases
Solution Approach 1:
The protective pad acts as a sacrificial intermediary that can be removed and cleaned separately. This eliminates the need to apply cleaning products directly to the ceramic glass cook-top surface, thereby preventing damage from abrasive cleaning products while maintaining cleanliness of both the pad and the cook-top.
5Adaptability or versatility
If multiple induction stoves are installed in hotels or dormitories, then accommodation capacity is improved, but cleaning time and labor increase
Solution Approach 1:
The protective pad is designed as a removable, separable component from the cook-top. This segmentation allows the pad to be easily removed and cleaned separately from the cook-top surface, significantly reducing cleaning time and labor for multiple stoves in hotels or dormitories while maintaining accommodation capacity.
Solution Approach 2:
The protective pad is extracted as a separate, removable component that can be taken off the cook-top for cleaning. This extraction allows the pad to be cleaned independently in a sink or dishwasher rather than requiring manual cleaning of the entire cook-top surface, thereby reducing cleaning time for multiple stoves.
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 pad system effectively reduces heat transfer to the cook-top, prevents scratches and cracking, enhances cleaning efficiency, and improves safety by containing spills and heat, making it suitable for residential and commercial use.
Implementation Method 1
the oscillating magnetic field causes the ferromagnetic material to heat up. The ferromagnetic material is heated by means of magnetic hysteresis loss in the ferromagnetic material
Implementation Method 2
as well as by eddy currents created in the ferromagnetic material (which generate heat due to the electrical resistance of the material)
Implementation Method 3
made of flexible, shock-absorbing materials like silicone rubber, which reduces heat transfer

AI summary
An induction stove assembly that utilizes pads between the cook-top of the stove and cooking vessels placed on the stove for heating. The pads are easily removable and interchangeable with other similar pads. The pads help protect the cook-top from damage, make clean-up more efficient, and insulate the cook-top from excessive heating.
