Cooking device door unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooking appliance doors require complex assembly processes due to separate components for inner and intermediate pane holding units, leading to increased assembly effort and potential misalignment during installation.
Innovation Solution
The inner and intermediate pane holding units are designed as a single assembly unit, with strip-shaped holding elements and elastic clamping elements to simplify assembly, and a symmetric design that allows for flexible use on both sides, reducing the need for additional components and installation space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If separate components are used for inner pane holding unit and intermediate pane holding unit, then each component can be independently manufactured, but assembly effort increases and misalignment occurs during installation
Solution Approach 1:
The patent combines the inner pane holding unit and intermediate pane holding unit into a single integrated assembly unit. This merging eliminates the need for separate installation of multiple components, reduces assembly effort, and prevents misalignment issues that occur when separate components are installed independently in the door base.
2Reliability
If multiple separate holding units are installed in the door base, then each pane can be securely held, but the number of components increases and assembly time increases
Solution Approach 1:
By integrating multiple holding functions into a single assembly unit, the patent maintains secure holding of both inner and intermediate panes while significantly reducing the number of separate components that need to be installed. This single unit can be installed as one piece, improving assembly speed without compromising holding reliability.
Solution Approach 2:
The assembly unit is designed to perform multiple functions simultaneously - holding both the inner pane and intermediate pane, providing mounting points for both panes, and ensuring proper alignment. This multi-functionality reduces the total component count while maintaining secure holding of multiple panes.
3Adaptability or versatility
If separate components are used for pane holding, then design flexibility is maintained, but additional components require additional installation space
Solution Approach 1:
The integration of multiple holding units into a single assembly unit consolidates the space required for installation. Instead of requiring separate installation spaces for multiple independent components, the unified design occupies a compact, optimized space in the door base while maintaining all necessary holding functions.
4Ease of manufacture
If separate holding units are used, then each unit can be optimized for its specific pane, but assembly effort and potential misalignment increase
Solution Approach 1:
By combining the holding units into a single integrated assembly, the patent ensures that alignment features and mounting points are pre-positioned with high precision during manufacturing. This eliminates misalignment issues that occur during field assembly of separate components, while still allowing each pane to be optimized for its specific requirements through the integrated design.

AI summary
The unit has an inner disk holding unit (14a) for an inner disk (16a), and an intermediate disk holding unit (18a) for an intermediate disk (22a). The holding units form a mounting unit for common mounting in a door base (12a), and designed as a single piece. The inner holding unit and/or the intermediate holding unit has strip-shaped holding elements (24a, 26a) for accommodating the inner and intermediate disks. The mounting unit has a stop element (42a) for a hinge element, and formed symmetrically to a transverse axis, where the door unit is mounted in a side area of the door base. An independent claim is also included for a method for mounting a cooking device door with a cooking device door unit.
