Guide Rail Fastening With Integral Latch for Oven Side Grates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening arrangements for fixing guide rails to side rails in pull-out guides, such as those in ovens, are complex and costly due to the need for additional holding elements that require welding, complicating manufacturing and assembly.
Innovation Solution
The guide rail incorporates integrally formed fastening means, including slots and a flexible latching web, allowing for secure attachment and alignment with bent end sections of the side rail without additional components, enabling easy manufacturing and assembly, and providing locking mechanisms to prevent accidental detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional holding elements are used to fix the guide rail to the side rail, then the attachment is secure, but the manufacturing complexity and cost increase due to welding requirements
Solution Approach 1:
The holding elements are integrated directly into the guide rail as integral formations, merging two separate components (guide rail and holding elements) into one unified structure. This eliminates the need for separate welding operations while maintaining secure attachment to the side rail.
Solution Approach 2:
The guide rail serves multiple functions: it provides the structural support for the pull-out guide and simultaneously incorporates the holding elements for attachment to the side rail. This multi-functionality reduces the need for additional specialized components and welding processes.
2Reliability
If additional holding elements are welded to the guide rail, then the attachment is secure, but the assembly process becomes more complex and time-consuming
Solution Approach 1:
The holding elements are formed as integral parts of the guide rail, combining the attachment function with the guide rail structure itself. This allows the guide rail to be installed as a single component without separate welding steps, significantly simplifying the assembly process.
3Reliability
If separate holding elements are used, then the attachment function is provided, but the manufacturing cost increases due to additional components and welding
Solution Approach 1:
The holding elements are manufactured as integral formations of the guide rail, merging the attachment function into the main component. This eliminates the need to manufacture, supply, and weld separate holding elements, thereby reducing manufacturing costs.
Solution Approach 2:
The complex welding process and separate holding element components are extracted from the manufacturing system by integrating the attachment function directly into the guide rail formation process, simplifying the overall manufacturing operation.
