Cooking Hob Display Frame With Sealing Lip for Dust-Free Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooking hobs face challenges in maintaining a dust-free intermediate space between the display and the viewing window due to manufacturing tolerances and the complexity of connecting components, which affects optical quality and dust prevention.
Innovation Solution
A single-piece display frame with a sealing lip and elastic elements is used to securely attach the display to the glass-ceramics panel, compensating for manufacturing tolerances and preventing dust entry, while a display carrier and snap-in mechanism provide additional support and attachment options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the display is pressed closely against the glass-ceramics panel to obtain sufficient optical quality, then optical quality is improved, but manufacturing tolerances cause different heights of the intermediate space making it difficult to maintain a defined constant distance
Solution Approach 1:
The display frame is designed with elastic elements at its lower side that enable dynamic adjustment and resilient support of the display. This allows the display to be pressed closely against the glass-ceramics panel for optimal optical quality while the elastic elements automatically compensate for height variations caused by manufacturing tolerances, maintaining a defined constant distance through elastic deformation.
Solution Approach 2:
The elastic elements change their physical state (deformation) in response to manufacturing tolerances, allowing the system to adapt the distance parameter dynamically. This enables maintaining both close contact for optical quality and constant distance for precision despite variations in component heights.
2Object-affected harmful factors
If the intermediate space between the glass-ceramics panel and the display is sealed to prevent dust entry, then dust prevention is improved, but the complexity of connecting components increases
Solution Approach 1:
The sealing lip and elastic elements are combined within one element, the display frame. This integration merges the sealing function and the resilient support function into a single component, preventing dust entry while compensating for manufacturing tolerances without increasing overall connection complexity.
Solution Approach 2:
The display frame serves multiple functions simultaneously: it provides structural support for the display, enables resilient positioning through elastic elements, and creates dust-proof sealing through the sealing lip. This multi-functionality eliminates the need for separate components for each function, reducing overall system complexity.
3Adaptability or versatility
If multiple separate components are used for sealing and elastic support, then functionality is improved, but the number of components and assembly complexity increases
Solution Approach 1:
The sealing lip and elastic elements are merged into one element, the display frame. This reduces the number of separate components while maintaining all necessary functions: sealing against dust and resilient support for tolerance compensation. The single-piece design simplifies assembly compared to multiple separate components.

Implementation Method 1
the elastic elements at its lower side... allow a resiliently supporting of the display on the control unit, so that manufacturing tolerances can be compensated
Implementation Method 2
the sealing lip on its upper side... is pressed or can be pressed against the viewing window and allows a dust-free intermediate space between the display and the viewing window
