Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing baking ovens lack convenient usability, clear operability, and effective protection against liquids boiling over, with complex designs and inadequate fastening mechanisms for operating components.
Innovation Solution
The oven features a compact design with a functional support surface that absorbs weight forces using magnetic or electrostatic forces, a control unit for setting multiple cooking zones, and a bearing unit for axisless, shaftless mounting of the operating means, ensuring secure and intuitive operation with reduced cleaning effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the operating means is mounted using traditional axes or shafts, then the mounting is secure, but the design becomes complex and cleaning becomes difficult
Solution Approach 1:
The patent removes the traditional axis or shaft from the mounting structure, replacing it with a magnetic field-based fastening system. The operating means is held in position by magnetic attraction between the operating means carrier unit and the operating means itself, eliminating the need for mechanical rotation axes or shafts and simplifying both the mounting structure and cleaning procedures
Solution Approach 2:
The patent replaces the mechanical mounting system (axes, shafts, and fasteners) with a magnetic field-based system. The magnetic field generating means creates an attractive force that holds the operating means in position, substituting mechanical fastening with electromagnetic interaction, thereby reducing structural complexity while maintaining secure mounting
2Volume of moving object
If the cooking surface unit is positioned close to the operating means, then the design is compact, but protection against liquid spills is reduced
Solution Approach 1:
The patent introduces a vertical dimension to the arrangement by positioning the operating means carrier unit at a higher elevation than the cooking surface unit. This vertical separation creates a protective height difference that prevents liquid spills from reaching the operating means, while the overall appliance remains compact through efficient spatial arrangement in three dimensions
3Reliability
If the operating means is fixed firmly to the panel, then the operation is stable, but cleaning effort increases
Solution Approach 1:
The patent creates a dynamic mounting system where the operating means can be easily attached and detached through magnetic attraction. The operating means carrier unit provides a receiving area that accepts the operating means, allowing it to be firmly held during operation through magnetic force but easily removed for cleaning by overcoming the magnetic attraction, thus balancing operational stability with cleaning ease
Solution Approach 2:
The patent separates the operating means from the permanent structure through the use of the operating means carrier unit. This segmentation allows the operating means to be a removable component that can be detached for cleaning while maintaining stable operation when attached, dividing the system into separable functional units

Function Achieved in This Case
This configuration enhances usability, provides clear operability, protects against liquid spills, and simplifies cleaning by ensuring secure and easy attachment of the operating components, while maintaining a compact and aesthetically pleasing design.
Implementation Method 1
at least one magnetic field generating means (48e, 48), which is arranged at least partially behind the operating means (18e) in a frontal view of the operating means (18e)
Implementation Method 2
the functional support surface (16) is intended to absorb at least part of a weight force of an operating means (18) in a functionally coupled state
Implementation Method 3
a force based on electricity can act on the operating means, which is in particular pressing and/or rotating and/or pushing the operating means

AI summary
The invention relates to a domestic appliance device comprising at least one operating means support unit (10; 10a to 10d; 10f) made up of a panel unit (12; 12a to 12d; 12f) and differing in particular from a hob (14; 14a to 14d; 14f). In order to achieve a comfortable usability, it is proposed that the operating means support unit (10; 10a to 10d; 10f) comprises at least one function contact surface (16; 16f) provided to absorb at least a part of a weight force of an operating means (18; 18a to 18d; 18f) in a functionally coupled state.
