Front panel system for a cooking device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing panel systems for cooking appliances face limitations in design freedom, require additional processing steps for attachment, and incur higher costs due to the use of double-sided adhesive tape and complex assembly processes, especially when accommodating different materials with varying thermal expansion coefficients.
Innovation Solution
A panel system utilizing self-supporting panels with integrated first and second connecting means that allow linear displacement and pivoting of attachments, eliminating the need for a screen carrier and double-sided adhesive tape, and enabling easy repositioning of components without gluing or welding, thus simplifying assembly and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sandwich construction with double-sided adhesive tape is used, then design freedom is improved, but device complexity and cost increase
Solution Approach 1:
The patent removes the aperture carrier from the sandwich construction, leaving only the self-supporting screen with integrated connecting elements. This extraction eliminates the need for double-sided adhesive tape and complex assembly steps while maintaining design freedom through the integrated connecting elements that allow linear displacement and pivoting of attachments.
Solution Approach 2:
The connecting elements are integrated directly into the self-supporting screen, merging the functions of the screen and the mounting structure. This integration eliminates the need for separate aperture carriers and adhesive tapes, simplifying the overall construction while preserving the ability to accommodate various design requirements through linear displacement and pivoting movements.
2Reliability
If double-sided adhesive tape is used to compensate for thermal expansion, then reliability is improved, but cost and tolerances worsen
Solution Approach 1:
The connecting elements are designed to be dynamic rather than rigid, allowing linear displacement and pivoting movements. This dynamic design naturally accommodates thermal expansion differences between materials without requiring thick adhesive tapes, thereby maintaining reliability while improving manufacturing precision and reducing tolerances.
3Device complexity
If self-supporting switch front is used, then device complexity is reduced, but design freedom is limited
Solution Approach 1:
The connecting elements integrated into the self-supporting screen are designed to allow linear displacement and pivoting of attachments. This dynamic capability enables the simple self-supporting construction to accommodate various design requirements, including retractable control handles and repositionable components, thereby providing design freedom without increasing construction complexity.
4Adaptability or versatility
If additional elements are attached to base component, then functionality is improved, but manufacturing precision worsens due to welding or bonding
Solution Approach 1:
The connecting elements allow attachments to be positioned with linear displacement and pivoting movements before being fixed in place. This dynamic positioning capability enables precise attachment of additional elements without requiring welding or bonding processes, thereby improving manufacturing precision while maintaining attachment capability.
