Food cooking oven
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooking oven designs require users to completely open the door and use tools to easily move the glass panel from a retaining position, making it inconvenient for mounting, removing, and cleaning.
Innovation Solution
The oven features a push-push type connection mechanism and a profile that can be moved between retaining and release positions without tools, allowing for easy access and removal of the glass panel, and includes a pivot mechanism for the profile to facilitate its movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a screwdriver or tool is used to rotate the pivot to move the protrusion between locking positions, then the protrusion can be reliably locked or released, but the operation becomes complex and requires additional tools
Solution Approach 1:
The patent replaces the screwdriver-based mechanical system with a push-button actuation system. The button (23) directly actuates the protrusion (21) to move between locked and released positions, eliminating the need for rotational tools while maintaining reliable locking through the same protrusion-groove engagement mechanism.
Solution Approach 2:
The locking mechanism is designed to be self-operating through the push-button (23) that directly moves the protrusion (21) without requiring external tools. The user can easily switch between locked and released states by simply pressing the button, making the system self-service friendly.
2Ease of operation
If the door must be completely opened to access the locking mechanism, then the protrusion can be manipulated, but the operation becomes inconvenient and time-consuming
Solution Approach 1:
The push-button (23) is positioned and designed to be accessible before the door is fully opened. This allows the user to actuate the protrusion (21) to the released position in advance, preparing the system for panel removal without requiring complete door opening, thereby saving time and improving convenience.
Solution Approach 2:
The push-button (23) serves as an intermediary element that translates simple user pressure into the movement of the protrusion (21). This intermediary mechanism allows the user to operate the locking system without needing to access or manipulate the pivot directly, enabling operation with the door partially closed.
3Ease of manufacture
If a snap-fit connection is used to hold the profile in position, then the assembly is simple, but the profile cannot be easily moved between positions
Solution Approach 1:
The profile (19) is designed with dynamic positioning capability through the push-button (23) actuation system. The profile can transition between fixed (locked) and movable (released) states on demand, combining the simplicity of snap-fit assembly with the flexibility of easy repositioning through the same engagement mechanism.

AI summary
Oven for cooking food comprising: i) a casing (20) which defines a compartment (2) for cooking; ii) a door (3) which is movable between an open position in which it allows the access to the compartment (2), and a closed position in which it contributes to delimit the compartment (2); said door (3) comprising: - a first panel (4) that in the closed position of the door (3) contributes to delimiting said compartment (2); - a second panel (5) that in the closed configuration of the door (3) is at a greater distance from said compartment (2) than the first panel (4); - a first and a second bodies (6, 7) in support of the first and the second panels (4, 5); the first and second body (6, 7) being hinged to said enclosure (20) and having a preponderant longitudinal extension; - a profile (8) which is movable between a first position in which it contributes to retaining in position the first panel (4) and a second position in which allows the removal of the first panel (4) from the door (3); at least in the first position said profile (8) extending preponderantly along a side of said first panel (4) and along a direction that is transverse to the preponderant extension of the first and second bodies (6, 7); - connection means 9 of the push-push type to connect the profile (8) to remaining portions of the door (3).
