Oven Door Glass Panel Push-Push Locking for Tool-Free Removal
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 locking to a releasing position, making maintenance and cleaning inconvenient.
Innovation Solution
The oven incorporates a push-push type connection mechanism and a profile that can be moved between locking and releasing positions without tools, allowing for easier access and removal of the glass panel, enabling one-handed operation and tool-free installation/removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a screwdriver or tool is used to rotate the pivot and move the protrusion between locking positions, then the glass panel can be securely held or released, but the operation becomes complex and requires additional tools
Solution Approach 1:
The protrusion is designed to be movable between locking positions by simply pushing or pulling the glass panel itself, without requiring external tools. The panel's own movement actuates the protrusion to engage or disengage from the locking groove, making the system self-servicing.
Solution Approach 2:
The screwdriver or tool is completely removed from the system. The complex tool-based rotation mechanism is replaced by a direct mechanical coupling where the glass panel's linear movement directly actuates the protrusion's rotational movement between locking positions.
2Ease of repair
If the door is opened completely to access the locking mechanism, then the glass panel can be removed, but the process becomes time-consuming and inconvenient
Solution Approach 1:
The locking mechanism is pre-positioned and accessible at all times, even when the door is closed. The protrusion is constantly engaged with the locking groove, and the glass panel can be removed by simply pulling it outward, which automatically actuates the protrusion to disengage from the groove without requiring door opening or preliminary tool operations.
Solution Approach 2:
The locking function is segmented from the door opening operation. The protrusion and locking groove form an independent locking subsystem that operates separately from the door hinge mechanism, allowing panel removal to be decoupled from door opening requirements.
3Adaptability or versatility
If a pivot with a slot is used to rotate the protrusion, then the locking mechanism can be actuated, but the device complexity increases
Solution Approach 1:
The pivot, protrusion, and locking groove are merged into a single integrated mechanical assembly. The protrusion is directly coupled to the glass panel such that panel movement automatically rotates the protrusion around its pivot to engage or disengage from the locking groove, combining multiple functions into one simple mechanism.
Solution Approach 2:
The glass panel serves multiple functions: it is both the transparent viewing/cleaning surface and the actuating mechanism for the locking system. By attaching the protrusion directly to the panel, the panel's primary movement (pushing/pulling) simultaneously performs the locking/unlocking function, eliminating the need for separate actuating components.

AI summary
A food cooking oven having an enclosure, which defines a cooking compartment and a door, which is movable between an open position and a closed position, is disclosed. The door door may include a first panel, a second panel, which in a closed configuration has a greater distance from the compartment than the first panel. Additionally, a first and a second body for supporting the first and second panels is included. A profile is included, which is movable between a first position retaining the first panel and a second position permitting removal of the first panel from the door. A push-push type connector is included to retain the profile to the door.
