Oven Door Glass Retention With Spring Release for Easy Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oven door glass designs are difficult to clean due to the deposition of vapor and food particles, which dry and become hard to remove, and existing detachable solutions require complex assembly and disassembly processes, often requiring additional tools and effort.
Innovation Solution
The oven door features a spring-based glass retention system with profiles and channels that allow the inner and middle glasses to be easily detached and reattached manually without additional apparatus, using a segmented spring design that supports the glasses from multiple sides, enabling simple and reliable removal and reattachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If glasses are fixed to the oven door, then the glasses remain securely in place during operation, but the glasses become difficult to clean as vapor and food particles deposit and dry on the glass surface
Solution Approach 1:
The glass retention system is segmented into multiple independent springs (first spring for inner glass, second spring for middle glass) that can be independently activated. This allows the glass to be detached for cleaning while maintaining stable positioning during normal operation, resolving the contradiction between secure fixation and cleaning accessibility.
Solution Approach 2:
The spring-based retention system provides dynamic adjustment capability. The springs can be compressed to release the glass for cleaning, then automatically return to their original position to secure the glass during operation. This dynamic mechanism allows the system to adapt between two states: secure fixation during operation and easy release for cleaning.
2Ease of operation
If screw-type connections are used to make glasses attachable/detachable, then the glasses can be removed for cleaning, but users face difficulties or even fail in detaching/attaching the glasses
Solution Approach 1:
The complex screw-type connection mechanism is extracted and replaced with a simple spring-based retention system. The springs engage with the glass through a straightforward compression and release action, eliminating the need for screws, nuts, or other complex fastening components. This simplifies the assembly process while maintaining easy detachability for cleaning.
3Reliability
If multiple individual springs are used to support each glass, then each glass can be independently positioned, but the assembly requires more connection parts and mounting effort
Solution Approach 1:
While maintaining separate springs for the inner and middle glasses to ensure independent positioning, the design merges the overall assembly approach into a unified spring-based retention system. This standardized approach across both glass elements simplifies manufacturing and assembly compared to using different mechanisms for each glass, reducing the overall complexity despite having multiple springs.

AI summary
The present invention relates to an oven door (1) comprising a front panel (2) provided with an outer glass; side profiles (3,3') and an upper profile (4) behind the panel (2) for glass assembly; an inner glass (5) attached to said profiles (3,3',4) and at least one middle glass (6); and at least one spring (7) positioning said glasses (5,6). The side profiles (3,3') are positioned on two sides at the rear of the panel (2), whereas the upper profile (4) is positioned on the upper rear side of said panel (2) so as to join the side profiles (3,3') from their upper parts. Said glasses (5,6) are attached between said profiles (3,3',4).
