Solution Overview

Problem

Gas ovens with dividers face challenges in maintaining efficient combustion and temperature control across partitioned cooking spaces due to interference from waste gases and uneven air supply, leading to incomplete combustion and inconsistent cooking results.

Innovation Solution

The implementation of an auxiliary air supply unit that forcibly supplies fresh air to the first burner, located in the upper portion, and a separate exhaust system for the second burner, located in the lower portion, to prevent waste gas interference and ensure consistent combustion across both cooking spaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the cooking space is partitioned by a divider to create multiple cooking zones, then cooking versatility is improved, but air supply uniformity deteriorates leading to incomplete combustion

Engineering Contradiction:
Improvecooking versatilityVSAvoidcombustion completeness
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The air supply system is segmented into multiple independent air supply units, with each unit responsible for a specific burner zone. This segmentation allows each burner to receive adequate air supply independently, preventing incomplete combustion while maintaining the divided cooking space structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different air supply strategies are applied to different zones based on their specific combustion requirements. The first air supply unit serves the first burner with appropriate air flow, while the second air supply unit serves the second burner separately, ensuring each zone has optimized air supply quality for complete combustion.

Inventive Principle:
Principle #3Local quality

2Device complexity

If waste gases from the second burner are not separately exhausted, then device complexity is reduced, but harmful gas interference increases affecting combustion quality

Engineering Contradiction:
Improveexhaust system complexityVSAvoidwaste gas interference
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The exhaust system is segmented into separate exhaust pathways for different burners. The first exhaust unit handles waste gases from the first burner, while the second exhaust unit handles waste gases from the second burner independently, preventing cross-contamination and harmful gas interference in the cooking spaces.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Separate exhaust units act as intermediaries between each burner and the external environment, channeling waste gases through dedicated pathways that prevent mixing with fresh air supplies and eliminate harmful gas interference with combustion processes.

Inventive Principle:
Principle #24Intermediary (Mediator)
