Solution Overview

Problem

Existing steam ovens require significant installation space and are prone to contamination during cooking due to the means used for distributing cleaning compositions, which disrupt the cooking process and are not thoroughly cleaned.

Innovation Solution

A removable cleaning insert with a receiving means for a cleaning unit, allowing for reversible attachment and positioning within the cooking space, ensuring thorough cleaning without occupying essential cooking space and minimizing contamination risks, featuring a supporting body and adjustable feet for secure placement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If means are configured on the cooking chamber wall for receiving and distributing cleaning composition, then cleaning function is provided, but installation space is consumed and contamination accumulates

Engineering Contradiction:
Improvecleaning functionVSAvoidinstallation space
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The cleaning composition receiving and distributing means are extracted from the fixed cooking chamber wall structure and transformed into a removable cleaning insert that can be taken out after use. This allows the cleaning function to be provided while minimizing permanent installation space requirements and enabling easy removal for cleaning maintenance.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The cleaning insert is designed with reversible fixation to the cooking chamber wall, allowing it to be dynamically installed and removed. This dynamic configuration enables the cleaning means to occupy space only when needed for cleaning operations, rather than permanently consuming installation space.

Inventive Principle:
Principle #15Dynamics

2Reliability

If cleaning means are fixed on the cooking chamber wall, then cleaning composition can be distributed, but the cooking process is disrupted and stubborn contaminants accumulate

Engineering Contradiction:
Improvecleaning composition distributionVSAvoidcontaminant accumulation
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The cleaning insert with its receiving and distributing means is extracted as a separate removable unit. After distributing the cleaning composition, the entire insert can be removed and taken out of the cooking chamber, preventing long-term contaminant accumulation on fixed surfaces and eliminating disruption to the cooking process.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The cleaning insert is designed to be discarded (removed) after completing its cleaning function. The insert itself can be cleaned or replaced, while the cooking chamber wall remains clean and undisturbed, preventing stubborn contaminant accumulation on the main cooking surfaces.

Inventive Principle:
Principle #34Discarding and recovering

3Area of stationary object

If cleaning insert is removable, then cooking space is maintained and cleaning unit can be positioned centrally, but reversible fixation mechanism is required

Engineering Contradiction:
Improvecooking space availabilityVSAvoidreversible fixation mechanism
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The cleaning insert is designed with a universal reversible fixation mechanism that can be easily attached and detached from the cooking chamber wall. This simple yet effective fixation system enables the cleaning insert to be reliably installed when needed while allowing quick removal to maintain full cooking space availability, without requiring complex mechanisms.

Inventive Principle:
Principle #6Universality (Multi-functionality)
