Solution Overview

Problem

Homeowners and small restaurants often cannot afford multiple cooking appliances, limiting the variety of food they can prepare based on the available appliance type, as each appliance serves a unique cooking function.

Innovation Solution

A versatile cooking appliance that can be easily converted between oven, grill, charcoal grill, and smoker functions, featuring multisided elements with rotating and adjustable cooking surfaces, allowing simultaneous use of different cooking methods like grilling and smoking.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple separate cooking appliances are purchased to provide different cooking functions, then the variety of cooking methods available is improved, but the cost and space requirements increase

Engineering Contradiction:
Improvecooking function varietyVSAvoidnumber of appliances
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a single cooking appliance that can perform multiple cooking functions including grilling, smoking, and roasting by incorporating different cooking surfaces (grill grate, smoker box, roasting pan) that can be interchangeably positioned on the heat source assembly, eliminating the need for multiple separate appliances

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

Solution Approach 2:

The cooking appliance is divided into separable functional components including the heat source assembly, multiple cooking surfaces, and support structures that can be independently positioned or removed, allowing the same base unit to serve different cooking purposes through reconfiguration

Inventive Principle:
Principle #1Segmentation

2Device complexity

If a single cooking appliance is used to reduce cost and simplify setup, then the device complexity is reduced, but the ability to perform different cooking functions is limited

Engineering Contradiction:
Improvenumber of appliancesVSAvoidcooking function variety
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The appliance incorporates movable and adjustable components including the heat source assembly that can be raised or lowered, cooking surfaces that can be repositioned, and a rotisserie mechanism that can be adjusted to different heights and speeds, enabling the same structure to adapt to different cooking requirements

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent uses interchangeable cooking surfaces and accessories as intermediary elements that can be placed on the heat source assembly to transform the basic appliance into different types of cooking devices (grill, smoker, roaster) without modifying the core structure

Inventive Principle:
Principle #24Intermediary (Mediator)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Enables a single appliance to perform multiple cooking functions, providing flexibility and versatility in food preparation, allowing for a wider range of culinary options without the need for multiple appliances.

Implementation Method 1

The various cooking surfaces can be elongated and arranged to form a multisided element with the various cooking surfaces placed about a longitudinal axis whereby a particular cooking surface can be presented by rotating the multisided element

Methodology Applied
Scientific EffectRotation:

Implementation Method 2

The source of heat can be, for example, an electric heater, a gas burner, charcoal, or wood

Methodology Applied
Scientific EffectThermal conduction: Conduction (thermal)

Implementation Method 3

a gas burner, charcoal, or wood

Methodology Applied
Scientific EffectCombustion: Combustion

Implementation Method 4

smokers that use these sources and also a source of smoke, such as wood chips

Methodology Applied
Scientific EffectSmoke generation: Smoke

AI summary

A cooking appliance includes at least one multisided element that has more than one cooking surface, the multisided element being mounted on a base so that it can be oriented to present one of the surfaces for cooking. The element can be rotated to present another cooking surface whereby a user can choose a surface to grill food, bake food, smoke food, and the like all with the one appliance. As well, the sources of heat can be gas, wood, charcoal, or other sources.
