Oven Door Glass Panel Removal Using Tool-Free Push-Push Connector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooking ovens 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 design 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 convenient cleaning and maintenance without the need for tools.
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 and releasing positions, then the glass panel can be securely held or released, but the operation becomes inconvenient and requires tools
Solution Approach 1:
The protrusion is designed to be movable between locking and releasing positions by the user directly, without requiring external tools. The user can manually push the protrusion to switch between positions, making the system self-servicing and tool-free for operation.
Solution Approach 2:
The screwdriver or tool is extracted from the system by replacing it with a direct manual operation mechanism. The protrusion itself becomes the operational element that the user can manipulate directly, removing the need for separate tooling.
2Ease of manufacture
If the door must be completely opened to access the glass panel for maintenance, then the panel can be accessed for cleaning, but the operation becomes inconvenient and time-consuming
Solution Approach 1:
The door assembly is segmented into functional zones, with the glass panel and its support structure (including the movable protrusion) designed as an accessible subsystem. This allows the panel to be serviced independently without requiring complete door disassembly or opening.
Solution Approach 2:
The movable protrusion mechanism is pre-configured to allow quick transition between locking and releasing states. This preliminary design enables rapid access to the glass panel without time-consuming door opening procedures.
3Adaptability or versatility
If a pivot with a slot is used to rotate the protrusion, then the protrusion can switch between positions, but the mechanism becomes complex and requires tools
Solution Approach 1:
The pivot and slot mechanism is extracted and replaced with a simpler direct-manual protrusion. This eliminates the rotational component and slot geometry, reducing mechanical complexity while maintaining the position-switching function.
Solution Approach 2:
Instead of using a rotational pivot mechanism to switch positions, the design inverts the approach by using a linearly movable protrusion that can be directly pushed by the user. This simplifies the mechanism from rotational to translational motion.

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 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.
