Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hob designs lack enhanced comfort and durability, particularly in terms of scratch resistance and aesthetic appeal, with existing coatings not effectively providing a ceramic appearance or sufficient protection for electronic components.
Innovation Solution
A hob with a base body made from a glass-like material or composite, featuring a ceramic appearance coating applied via sol-gel or PVD methods, including recesses for light transmission and filled with translucent materials to prevent soiling, which also serves as a user interface, enhancing scratch resistance and visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a coating is applied to the hob plate to provide ceramic appearance and protection, then aesthetic appeal and scratch resistance are improved, but the coating may not provide sufficient protection for electronic components and may require additional display panels
Solution Approach 1:
The patent combines the protective coating function with the display function by integrating recesses directly into the coating layer. This merging eliminates the need for separate display panels while maintaining both protection and information display capabilities, thereby reducing device complexity without sacrificing scratch resistance.
Solution Approach 2:
The coating is designed to serve multiple functions simultaneously: providing ceramic appearance, ensuring scratch resistance, protecting electronic components, and enabling light transmission for display purposes. This multi-functionality approach eliminates the need for additional dedicated display panels, reducing overall device complexity.
2Ease of operation
If recesses are created in the coating for light transmission, then visibility and user interface functionality are improved, but the coating structure becomes more complex and may be more prone to soiling
Solution Approach 1:
The patent fills the recesses with translucent material that acts as a thin film barrier, allowing light to pass through while preventing contaminants from entering and soiling the recess areas. This maintains user interface visibility while protecting against soiling.
Solution Approach 2:
The use of translucent material in the recesses creates optical contrast that enhances visibility of the user interface elements while maintaining a clean appearance. The material allows light transmission for visibility but prevents actual soiling of the recess structures.
3Strength
If the coating is made highly durable with high Mohs hardness, then scratch resistance is improved, but the coating may become less translucent and harder to manufacture with precision recesses
Solution Approach 1:
The patent adjusts the Mohs hardness of the coating to an optimal range (at least 4, preferably at least 5) that provides sufficient scratch resistance while remaining compatible with laser processing methods. This parameter optimization ensures both durability and manufacturability of precise recesses.
Solution Approach 2:
The patent replaces traditional mechanical machining methods with laser processing methods for creating recesses in the hard coating. This substitution enables precise recess formation in coatings with high Mohs hardness that would be difficult or impossible to machine mechanically, thereby maintaining both scratch resistance and manufacturing precision.

AI summary
The invention proceeds from a panel unit (12a; 12b), in particular a panel unit (12a; 12b) of a hob (10a; 10b), having at least one main body (40a; 40b) and at least one coating (42a; 42b, 43b), which is arranged in at least one sub-region at least of one side of the main body (40a; 40b). In order to enhance product desirability, it is proposed that the coating (42a; 42b, 43b) should be provided such that it at least has a ceramic appearance.
