Oven Rack System with Removable Posts and Channel Mounting Blocks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rack systems for cooking appliances lack efficient retention, adjustment, and extension mechanisms, making them difficult to position, remove, and maintain within the appliance cavity.
Innovation Solution
A rack system featuring a support unit with rack support bars and connecting members, coupled with mounting blocks that allow for slidable and removable installation, enabling precise positioning and easy maintenance by utilizing channels and notches for secure engagement and disengagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional rack systems are used with fixed support structures, then structural stability is maintained, but ease of operation for insertion and removal deteriorates
Solution Approach 1:
The rack system is divided into separate components: the rack body with support bars and the separate mounting blocks with channels. This segmentation allows the rack to be easily inserted and removed while the mounting blocks remain fixed in the appliance, resolving the contradiction between ease of operation and structural stability.
Solution Approach 2:
The channels in the mounting blocks serve as intermediary structures that guide and receive the posts on the rack. This intermediary mechanism facilitates easy insertion and removal while maintaining stable support when the rack is in position, without requiring complex fixed support structures.
2Ease of repair
If racks are made permanently fixed for stability, then reliability is improved, but ease of repair and maintenance deteriorates
Solution Approach 1:
The system transitions from a static fixed connection to a dynamic removable connection. The rack can be easily removed from the channels and reinstalled, facilitating maintenance and repair while the channels provide stable retention when the rack is in use. The posts fit tightly in the channels during operation but can be easily removed when needed.
3Adaptability or versatility
If adjustment mechanisms are added for positioning flexibility, then adaptability is improved, but device complexity deteriorates
Solution Approach 1:
Instead of complex adjustment mechanisms along the rack length, the system uses the vertical dimension with multiple mounting blocks positioned at different heights in the appliance. This allows rack positioning flexibility through simple vertical placement options rather than complex horizontal adjustment mechanisms.

AI summary
A rack system for a cooking appliance cavity includes a first support unit including a plurality of rack support bars and a first connecting member defining a body portion having the support bars coupled therewith, a first end with a first post and a first stepped segment between the first post and the body portion, and a second end with a second post and a second stepped segment between the second post and the body portion. The system further includes first and second mounting blocks, each defining a channel and a notch extending intersecting with the channel such that a first portion of the channel is open and a second portion of the channel is enclosed. The first and second posts are respectively received in the second portions of the channels of the first and second mounting blocks.
