Solution Overview

Problem

Conventional gas ovens struggle to efficiently utilize the entire cooking cavity and simultaneously operate multiple burners due to air supply and discharge issues, leading to incomplete combustion and limited cooking flexibility.

Innovation Solution

A gas oven design featuring a divider to create separate cooking cavities with independent air supply and discharge systems, including a subsidiary air supplying device with a fan to forcibly supply air and a subsidiary air discharging device to manage waste gases, allowing for simultaneous operation of multiple burners and customizable cooking modes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single cooking cavity is used, then the structure is simple, but the cooking flexibility and area utilization are limited

Engineering Contradiction:
Improvecooking flexibilityVSAvoidcavity structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cooking cavity is divided into multiple individual cooking cavities (first cooking cavity, second cooking cavity, etc.) using detachable dividers. This segmentation allows the oven to function as multiple separate compartments for simultaneous different cooking tasks, or as a single large cavity when dividers are removed, thus improving cooking flexibility without permanent structural complexity

Inventive Principle:
Principle #1Segmentation

2Productivity

If multiple burners are operated simultaneously in a single cavity, then cooking capacity increases, but air supply becomes insufficient causing incomplete combustion

Engineering Contradiction:
Improvecooking capacityVSAvoidcombustion completeness
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

Multiple burners are distributed across separate cooking cavities created by dividers. Each cavity has its own air supply passage, allowing each burner to receive adequate air independently. This prevents incomplete combustion while maintaining high cooking capacity through simultaneous operation of multiple burners in different compartments

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The air supplying passages act as intermediaries that deliver fresh air to each burner's combustion zone. By providing dedicated air supply routes to each cavity, the system ensures sufficient oxygen supply for complete combustion even when multiple burners operate simultaneously, resolving the air supply bottleneck

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If a divider is mounted to create separate cavities, then cooking flexibility improves, but air flow between cavities is blocked

Engineering Contradiction:
Improvecooking mode optionsVSAvoidair flow
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The air supply system is segmented into multiple independent passages, each serving specific cooking cavities. When dividers are mounted, the system uses dedicated air supply passages for each cavity, ensuring that air flow is not blocked by the presence of dividers. Each passage is routed to provide air to its corresponding cavity independently

Inventive Principle:
Principle #1Segmentation

4Area of stationary object

If the entire cooking cavity is used, then the cooking area is maximized, but waste gas accumulation occurs

Engineering Contradiction:
Improvecooking areaVSAvoidwaste gas accumulation
Core Design Contradiction:
Area of stationary objectVSObject-generated harmful factors

Solution Approach 1:

The waste gas discharge system is divided into multiple independent discharging passages, each associated with specific cooking cavities. This segmentation allows waste gases from different cavities to be discharged separately and efficiently, preventing accumulation even when the entire cooking area is in use. Each passage provides a direct escape route for combustion byproducts

Inventive Principle:
Principle #1Segmentation

AI summary

A gas oven configured to use a single cooking cavity (40) being divided into a plurality of individual cooking cavities (41, 42) by mounting a divider (43) at the cooking space. The gas oven includes a forced air supplying device (100) capable of forcedly supplying air to the individual cooking space at an upper portion of the cooking space, and a natural air discharging device (200) capable of naturally discharging waste air of the individual cooking space at a lower portion of the cooking space, when each individual cooking space is shut off by the divider.
