Cooking device with specific attachment of a support rail for a food product carrier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cooking appliances with a baffle wall in the cooking chamber face a challenge in accommodating additional components due to the reduced depth space, which restricts the installation of receiving rails and compromises their secure and compact positioning.
Innovation Solution
A cooking appliance design that incorporates a separate mounting rail extending into the intermediate space behind the baffle wall, secured by a holding device, allowing for the installation of additional components without further reducing the depth space, and featuring a compact, stable retaining rail that can be mounted securely to the rear and baffle walls, ensuring positional stability and concealed placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a baffle wall is installed in the cooking chamber to separate spaces, then the cooking chamber is divided into functional zones, but the depth space available for mounting rails and food carriers is reduced
Solution Approach 1:
The mounting rail is configured to extend in multiple directions: vertically along the baffle wall and horizontally into the gap space. This multi-dimensional arrangement allows the rail to utilize both the vertical height and the horizontal gap depth, effectively overcoming the limited depth space constraint while maintaining functional zoning.
Solution Approach 2:
The retaining device is integrated into the baffle wall structure, with the mounting rail nested between the baffle wall and the food carrier. This nested arrangement allows the rail system to be compactly positioned within the existing gap space without requiring additional external mounting structures.
2Reliability
If the mounting rail extends behind the baffle wall into the gap space, then the rail can be securely positioned without further reducing cooking chamber depth, but the rail placement becomes more complex
Solution Approach 1:
The retaining device features self-retaining characteristics where the mounting rail automatically engages with the baffle wall structure upon insertion. The rail's rear end is retained by the retaining device without requiring additional fastening operations, allowing the system to secure itself during the mounting process.
Solution Approach 2:
The mounting rail is divided into distinct functional segments: a vertical portion mounted on the baffle wall and a horizontal portion extending into the gap. This segmentation allows each portion to be optimized independently for its specific function while simplifying the overall installation process through modular assembly.
3Strength
If a retaining device is used to hold the rear end of the mounting rail in the gap space, then the rail can securely support heavy food carriers, but the device requires additional components
Solution Approach 1:
The retaining device is merged with the baffle wall structure, where the baffle wall itself serves as the mounting surface and structural support. This integration eliminates the need for separate mounting brackets or attachment mechanisms, reducing component count while maintaining strength.
Solution Approach 2:
The baffle wall serves multiple functions: it acts as a structural divider, a mounting surface for the retaining device, and a support structure for the mounting rail. This multi-functionality reduces the need for additional components while maintaining the required weight bearing capacity.
