Solution Overview

Problem

Conventional ovens face limitations in space utilization and airflow control when using accessories like smokers, as they occupy cooking space and can disrupt the cooking process, especially when removing hot ash, which can be dangerous and inconvenient.

Innovation Solution

An oven design with a base cavity for receiving energy accessories, allowing for safe and convenient access without disturbing the cooking process, with an aperture for energy flow into the oven chamber, maintaining airflow control and compact dimensions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If an accessory such as a heat source or smoker is placed inside the oven chamber, then the accessory can supply energy to cook or cure foodstuff, but the accessory takes up cooking space and reduces the amount of food that can be cooked

Engineering Contradiction:

Improveenergy supply to cook foodVSAvoidcooking space

Core Design Contradiction:

Use of energy by moving objectVSVolume of moving object

Solution Approach 1:

The accessory is relocated from the horizontal cooking space to the vertical dimension by placing it in a cavity in the base of the oven. This dimensional change allows the accessory to remain accessible and functional while preserving the entire oven chamber volume for food storage and cooking.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Object-generated harmful factors

If an accessory is placed inside the oven chamber, then the accessory can supply smoke or heat, but the accessory affects airflow regulation and requires interruption of the cooking process for removal

Engineering Contradiction:

Improvesmoke and heat supplyVSAvoidairflow control and process continuity

Core Design Contradiction:

Object-generated harmful factorsVSEase of operation

Solution Approach 1:

The accessory is extracted from the oven chamber interior and positioned in a cavity in the base. This extraction eliminates the accessory's interference with airflow patterns and cooking space while maintaining its ability to generate smoke and heat that can be directed into the chamber through a dedicated aperture.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

A smoke inlet aperture is introduced as an intermediary element between the accessory cavity and the oven chamber. This aperture controls the flow of smoke and heat from the accessory to the chamber, enabling regulated transfer without direct placement of the accessory inside the chamber.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Temperature

If an accessory with hot ash is placed in the oven chamber, then the accessory can provide heat, but removal of the accessory becomes dangerous and difficult

Engineering Contradiction:

Improveheat generationVSAvoiddanger from hot ash

Core Design Contradiction:

TemperatureVSObject-affected harmful factors

Solution Approach 1:

The accessory containing hot ash is extracted from the oven chamber and positioned in an accessible cavity in the base. This allows the user to remove and handle the hot accessory safely from outside the chamber, eliminating the danger of reaching into a hot chamber to retrieve the accessory.

Inventive Principle:

Principle #2Taking out (Extraction)

4Ease of operation

If the oven is designed with a cavity in the base for accessory storage, then the accessory port can be accessed safely without disturbing cooking, but the base structure becomes more complex

Engineering Contradiction:

Improvesafe accessory accessVSAvoidbase structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The accessory cavity is merged with the base structure, integrating the storage function into the existing support framework. This consolidation adds minimal structural complexity while providing safe and convenient accessory access from the exterior of the oven.

Inventive Principle:

Principle #5Merging (Combining)
