Solution Overview

Problem

Existing oven drip trays with steam functions are not securely attached, leading to unintentional detachment and insufficient capacity for collecting condensate, especially when the oven door is frequently opened or used for high-water content cooking, resulting in condensate leakage onto furniture and floors.

Innovation Solution

A drip tray with a snap hook design that provides a secure, detachable, and easily removable attachment to the oven, featuring a transversely extending tongue and projection for positive engagement with oven components, allowing controlled detachment and a large enough capacity to handle excess condensate, along with an overflow mechanism to prevent leakage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the drip tray is detachably mounted via rail-like guide with fastening elements, then the drip tray is removable for cleaning or emptying, but the drip tray is not securely attached and can be easily removed unintentionally

Engineering Contradiction:
Improveremovability for cleaningVSAvoidsecure attachment
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The snap hook incorporates a spring element that enables dynamic engagement and disengagement. The spring-loaded tongue automatically engages with the mounting element during installation, providing secure attachment, while allowing controlled release through sufficient pulling force, enabling easy removal for cleaning.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The connection strength is made variable through the spring mechanism. When installed, the spring maintains engagement force for secure attachment. When removal is needed, applying sufficient pulling force overcomes the spring force, releasing the connection. This parameter change allows the same structure to provide both secure attachment and easy removal.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If the drip tray is permanently attached to the door or oven flange, then the attachment is secure, but the drip tray is difficult to access for cleaning and emptying

Engineering Contradiction:
Improvesecure attachmentVSAvoidaccessibility for cleaning
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The drip tray is designed as a separate, detachable component rather than being permanently integrated into the door or oven flange. The snap hook connection divides the system into removable tray and fixed mounting elements, allowing the tray to be easily detached for cleaning while maintaining secure attachment during use.

Inventive Principle:
Principle #1Segmentation

3Quantity of substance

If the drip tray has a large capacity to handle excess condensate, then the collection capability is improved, but the drip tray may become heavier or more difficult to remove

Engineering Contradiction:
Improvecondensate capacityVSAvoidremovability
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The spring-loaded snap hook provides dynamic connection that can accommodate the weight of a full drip tray. The spring force adjusts to maintain secure engagement even when the tray contains significant condensate, while still allowing removal when sufficient force is applied.

Inventive Principle:
Principle #15Dynamics

4Ease of manufacture

If the snap hook is designed for automatic engagement, then the attachment is simplified, but the release mechanism may require significant force

Engineering Contradiction:
Improveautomatic engagementVSAvoidrelease force required
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The snap hook automatically engages with the mounting element during installation without requiring manual intervention. The spring-loaded tongue self-activates to secure the connection. For release, the design accepts that user-applied force is needed to overcome the spring engagement, balancing automatic installation with controlled removal.

Inventive Principle:
Principle #25Self-service

AI summary

The invention relates to a drip tray (2) for collecting condensate from an oven (4), comprising a tray-shaped collection section (12) extending substantially in a longitudinal direction, and at least one snap hook (24) fixedly connected to the collection section (12) and extending substantially in a transverse direction away from the collection section (12), which is designed to engage a component of the oven (10) in a form-fitting manner in the transverse direction, and whose form-fitting engagement can be manually released to detach the drip tray (2) from the oven component (10). The invention further relates to an oven (4) comprising a cooking chamber, a door (6) for closing the cooking chamber, and such a drip tray (2), wherein the drip tray (2) is arranged vertically below the door (6).
