Split Oven Door Lift Assembly for Reduced Weight and Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional oven doors, especially in larger ovens, are heavy, slow to operate, and require significant space, limiting efficiency and functionality due to their size and operation mechanisms.
Innovation Solution
The implementation of a split door oven design where multiple doors can operate independently, using a lift assembly with grooves and projections to guide the doors along orthogonal and parallel paths, allowing for efficient movement and reduced space requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large single door is used for a large oven, then the oven can be sealed properly, but the door becomes heavy and slow to operate
Solution Approach 1:
The oven door system is divided into multiple independent doors (first door and second door) that can operate separately. Each door has its own drive assembly and operates independently to cover the oven opening, replacing the conventional single large door while maintaining sealing capability and reducing individual door weight.
2Reliability
If a large single door is used for a large oven, then the oven can be sealed properly, but the door requires large space to operate
Solution Approach 1:
The oven door system is divided into multiple independent doors (first door and second door) that can operate separately. Each door has its own drive assembly and operates independently to cover the oven opening, replacing the conventional single large door while maintaining sealing capability and reducing individual door weight.
Solution Approach 2:
The doors move along orthogonal paths (first door along first path, second door along second path) rather than a single swing arc, allowing compact arrangement and reducing the space required for door operation while maintaining effective sealing.
3Speed
If multiple independent doors are used instead of a single door, then the doors weigh less and operate faster, but the device complexity increases
Solution Approach 1:
The drive assemblies for both doors are integrated into a single oven door operating frame structure. The frame includes panels with grooves that guide both doors, and the drive assemblies are mounted on the same frame, sharing common structural elements and reducing overall system complexity despite having multiple doors.

AI summary
An oven comprising a multi-door operating apparatus is provided. In one example, the multi-door operating apparatus comprises a first panel comprising a first plurality of grooves that traverse a first inside surface of the first panel and a second panel comprising a second plurality of grooves that traverse a second inside surface of the second panel, wherein first inside surface faces the second inside surface, and wherein the first plurality of grooves and the second plurality of grooves extend in a first direction and then turn to extend in a second direction. The multi-door operating apparatus further comprises two or more oven doors configured to move in the first direction and turn to the second direction via projections that extend from the respective oven doors into the first plurality of groves and the second plurality of grooves.
