Oven Guide Rail Fixing Wire for Stable Shelf Withdrawal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oven guide rail systems are unstable during shelf withdrawal and difficult to clean due to the use of fixing wires, which are not securely connected to the rails.
Innovation Solution
The oven features a fixing wire that connects and stabilizes guide rails with a step-structured contact unit, allowing for secure coupling and easy cleaning by positioning the wire between the rails and forming a closed loop for enhanced stability and accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a fixing wire is press-fitted to a bracket provided at the rail, then the fixing wire can be installed quickly, but cleaning the fixing wire by separating is difficult and the fixing wire cannot stably connect the rail
Solution Approach 1:
The fixing wire is divided into multiple contact units, each independently contacting the rail. This segmentation allows each contact unit to be cleaned separately while maintaining overall stability, resolving the contradiction between easy installation and easy cleaning.
Solution Approach 2:
The fixing wire transitions from a static press-fitted connection to a dynamic structure where contact units can move independently along the rail. This dynamic capability enables the fixing wire to maintain stable connection while allowing access for cleaning operations.
2Ease of manufacture
If a fixing wire is press-fitted to a bracket provided at the rail, then the fixing wire can be installed quickly, but the fixing wire may not be able to stably connect the rail
Solution Approach 1:
The fixing wire is segmented into multiple contact units that independently contact the rail at different positions. This segmentation distributes the connection load and prevents the wire from rotating or detaching, achieving stable connection while maintaining easy installation.
Solution Approach 2:
Different portions of the fixing wire have different contact characteristics - contact units at different positions provide localized stabilization. This local quality approach ensures the wire remains stable at critical points while allowing flexibility elsewhere.
3Adaptability or versatility
If each rail is separately moved, then the guide rails can be independently adjusted, but inconvenience is present when a user withdraws and settles the shelf member from the rails
Solution Approach 1:
The fixing wire merges the function of connecting multiple rails into a single component. This combination allows the rails to be adjusted independently while maintaining coordinated movement, resolving the contradiction between adjustment flexibility and operational convenience.

AI summary
Disclosed herein is an oven having guide rails. The oven includes a coking compartment, a shelf member disposed at an inside the cooking compartment and provided such that food substance is mounted, a plurality of guide rails installed such that the shelf member is withdrawn from the cooking compartment, and a fixing wire installed as to connect the plurality of guide rails and having a plurality of contact units configured to make contact with the plurality of guide rails, respectively, and the at least one contact unit is formed while provided with a step. The left and right movements of guide rails may be able to be stabilized by use of the fixing wire stably coupled to the guide rails.
