Partitioned Oven Door Assembly for Selective Heat-Sealed Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ovens lack a flexible door structure that can efficiently open and close both the entire cooking space and individual cooking spaces, leading to inefficiencies in power consumption and safety concerns when using only a portion of the cooking space.
Innovation Solution
The oven features a detachable partition member that allows for four operational modes, with a door assembly comprising a main door and individual doors that can be opened and closed independently, ensuring hermetic sealing and efficient use of the cooking space, and includes hinge devices and sealing members for precise control and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single door structure is used to cover the entire cooking space, then the door can open and close the whole cooking space, but it cannot selectively open and close individual cooking spaces
Solution Approach 1:
The door assembly is segmented into a main door and multiple individual doors (first individual door, second individual door). Each door can be independently opened or closed to access specific cooking spaces. The main door provides access to the entire cooking chamber, while individual doors provide selective access to partitioned cooking spaces, enabling versatile operation modes without requiring a completely complex reconfiguration system.
Solution Approach 2:
The door assembly serves multiple functions: the main door can open the entire cooking chamber, individual doors can open specific cooking spaces, and combinations thereof provide different access configurations. This multi-functional design allows the same door structure to handle various cooking scenarios (single large dish, multiple small dishes, simultaneous cooking in different spaces) without requiring separate specialized door mechanisms for each case.
2Productivity
If the entire cooking space is operated, then large food items can be cooked, but power consumption increases
Solution Approach 1:
The cooking space is divided into multiple individual cooking spaces by partition members, allowing users to operate only the necessary portion of the cooking chamber. When cooking small food items, only specific individual cooking spaces need to be activated and accessed through their respective individual doors, rather than heating and maintaining the entire cooking chamber, thus reducing energy consumption while preserving cooking capacity for larger items when needed.
Solution Approach 2:
The partition members are detachably installed, allowing the cooking space configuration to be dynamically changed based on cooking needs. Users can install partitions to create smaller cooking spaces for energy-efficient operation with small food items, or remove partitions to create a large cooking space for big food items, making the system adaptable to different productivity requirements.
3Use of energy by moving object
If individual cooking spaces are operated, then power consumption is reduced, but sealing and heat loss control become more difficult
Solution Approach 1:
The sealing system is segmented with separate sealing members for each door type: a main sealing member for the main door and individual sealing members for each individual door. This segmentation allows each sealing member to be specifically designed and positioned to ensure hermetic sealing of its corresponding door, maintaining reliable sealing performance even when only individual cooking spaces are accessed and operated.
Solution Approach 2:
Different sealing members are positioned at specific locations corresponding to different doors (main door, first individual door, second individual door). Each sealing member provides localized hermetic sealing at its specific position, ensuring that when individual doors are opened or closed, only the necessary sealing actions occur at those local positions, maintaining thermal efficiency and preventing heat loss effectively.
4Ease of operation
If multiple doors are added for selective access, then individual cooking spaces can be accessed independently, but device complexity increases
Solution Approach 1:
The door assembly is segmented into a main door and multiple individual doors, each with its own hinge devices and sealing members. This segmentation provides ease of operation by allowing selective access to individual cooking spaces without opening the entire main door, reducing heat loss and improving safety. The modular nature of the segmentation keeps each component relatively simple while providing collective versatility.
Solution Approach 2:
The individual doors are nested within or attached to the main door structure, with each individual door providing access to its specific cooking space while being part of the overall door assembly. This nesting arrangement allows multiple doors to be integrated in a space-efficient manner, providing selective access functionality without proportionally increasing the overall complexity or space requirements of the door system.

AI summary
An oven (1) in which a cooking space (30) in a cooking chamber (20) is dividable into a plurality of individual cooking spaces (31, 32) by a partition member (40). The oven includes a door assembly (90) including a main door (100) rotatably combined with a main body (10) and provided with a plurality of openings (110, 120) corresponding to the respective plurality of individual cooking spaces and a plurality of individual doors (210, 220) rotatably combined with the main body to open and close the respective plurality of openings. The door assembly (90) may selectively open and close the entirety of the cooking space (30) or the respective plurality of individual cooking spaces (31, 32), and thus a heat loss or danger of burn generated due to opening of the main door (100) when only the individual cooking space (30) is used may be prevented.
