Cooking Compartment Side Frame With Elastic Snap-Fit Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inserting devices for cooking compartments are laborious to attach and require extensive procedures, leading to inefficiencies in fixing side frames and potentially causing tilting issues with supported items.
Innovation Solution
The use of elastically deformable accommodation regions, such as spring wires, with peripheral grooves on holding elements and U-shaped access openings allows for easy and secure fastening of side frames to the cooking compartment, compensating for tolerances and preventing tilting through indexing mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If individual guiding elements are detached and attached separately to side walls, then guiding elements can be removed when not needed reducing heating time, but the attachment procedure is extensive and laborious
Solution Approach 1:
The side frame is divided into modular components (guiding elements and side frame structure) that can be independently attached and detached. The holding devices are segmented into resilient accommodation elements that can be independently mounted on the side wall, allowing partial disassembly when certain guiding elements are not needed, thus reducing heating time while maintaining ease of attachment through the modular design
Solution Approach 2:
The resilient accommodation elements automatically perform the attachment function through their elastic properties. When the side frame is inserted, the resilient elements deform and then snap back to secure the holding devices in place without requiring manual fastening operations. The system serves itself by using the elastic deformation and recovery of the resilient elements to create the attachment action, eliminating the need for extensive manual attachment procedures
2Ease of operation
If holding devices directly contact holding elements, then attachment is simple, but tolerances cannot be compensated leading to potential instability
Solution Approach 1:
The resilient accommodation elements change their physical state (elastic deformation) to adapt to tolerance variations. When the side frame is attached, the resilient elements deform within their elastic range to accommodate dimensional tolerances of the holding elements, then maintain a stable engaged state. This parameter change (elastic deformation) allows the system to simultaneously achieve simple attachment operation and reliable stable attachment by absorbing tolerance variations
3Reliability
If vertical stops are added to guiding elements to prevent tilting, then baking tray tilting is reduced, but the device complexity increases
Solution Approach 1:
The tilting prevention function is merged into the holding devices themselves rather than being a separate component. The resilient accommodation elements are designed to provide both the attachment function and the tilting prevention function through their geometric configuration and elastic properties. The peripheral groove and the resilient element's deformation characteristics work together to create an indexing mechanism that prevents tilting while maintaining simple guiding element structure, thus reducing overall device complexity
