Oven
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ovens with partition members to divide cooking spaces lack an efficient door structure that allows selective opening and closing of the entire cooking space or individual spaces, leading to inefficiencies in power consumption and potential heat loss when only a portion of the space is used.
Innovation Solution
The oven features a door assembly with a main door and two individual doors that can be independently opened and closed, allowing for four operational modes: full space, dual individual spaces, single individual space, and single individual space operation, with sealing members and locking mechanisms to maintain hermetic seals and control door operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single main door is used to close the entire cooking space, then the structure is simple, but it cannot selectively open/close individual cooking spaces when partitioned
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, allowing selective access to different cooking spaces while maintaining the ability to close the entire cooking space when needed.
Solution Approach 2:
The door assembly provides dynamic configurability through multiple operational modes. The main door and individual doors can be combined in various configurations (main door only, main door with individual doors, individual doors only) to adapt to different cooking requirements and partition arrangements.
2Adaptability or versatility
If the entire cooking space is operated, then large food can be cooked, but power consumption increases
Solution Approach 1:
The cooking space is divided into multiple individual cooking spaces using partition members. This segmentation allows users to operate only the necessary cooking spaces for their specific cooking tasks, rather than heating the entire cooking chamber, thereby reducing power consumption while maintaining versatility.
Solution Approach 2:
Different regions of the cooking space can be independently activated. Users can select specific local areas (individual cooking spaces) for operation based on their cooking needs, rather than uniformly heating the entire space, optimizing energy efficiency.
3Ease of operation
If the main door is opened to access a specific cooking space, then access is achieved, but heat loss occurs from the entire cooking space
Solution Approach 1:
The door system is divided into a main door and individual doors corresponding to each cooking space. When access to a specific cooking space is needed, only the corresponding individual door needs to be opened while the main door and other individual doors remain closed, minimizing heat loss to the entire cooking space.
Solution Approach 2:
The door assembly provides localized access control. Each individual door can be opened independently to access its corresponding cooking space without affecting the thermal environment of other cooking spaces or requiring opening the main door, thereby reducing overall heat loss.
4Adaptability or versatility
If partition members are installed to divide cooking spaces, then individual cooking can be achieved, but the door structure must accommodate multiple configurations
Solution Approach 1:
The door assembly is segmented into a main door and multiple individual doors that correspond to the partitioned cooking spaces. This segmentation allows the door structure to flexibly accommodate different partition configurations and operational modes without requiring complex reconfiguration mechanisms.
Solution Approach 2:
The door assembly is designed with multi-functionality to handle various operational scenarios. The combination of a main door and individual doors allows the system to universally accommodate different partition member arrangements and support multiple operational modes (full space operation, individual space operation, selective access) with a single integrated structure.

AI summary
An oven in which a cooking space in a cooking chamber is dividable into a plurality of individual cooking spaces by a partition member. The oven includes a door assembly including a main door rotatably combined with a main body and provided with a plurality of openings corresponding to the respective plurality of individual cooking spaces and a plurality of individual doors rotatably combined with the main body to open and close the respective plurality of openings. The door assembly may selectively open and close the entirety of the cooking space or the respective plurality of individual cooking spaces, and thus a heat loss or danger of burn generated due to opening and closing the main door when only the individual cooking space is used may be prevented.
