Solution Overview

Problem

Existing grills using chemical fuels like charcoal and gas face challenges in fuel supply convenience, heat control, and maintaining cleanliness, particularly with oil stains from frying and grilling processes.

Innovation Solution

An electric arc grill is designed with an electric heating device, a fire gathering plate, a lifting device, and a grill carrier, where the electric heating device creates an electric arc to heat the fire gathering plate, enabling frying, grilling, and baking functions while incorporating features for easy cleaning and heat control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If chemical fuels like charcoal or gas are used in grills, then the grill can perform frying, grilling, and baking functions, but it becomes difficult to control heat intensity and heating area, leading to inconsistent cooking results

Engineering Contradiction:
Improveheat controlVSAvoidcooking consistency
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The heating system is divided into multiple independent electric heating components (heating rods) that can be individually controlled. Each heating rod corresponds to a specific heating zone, allowing independent control of heat intensity and heating area for different cooking requirements, thus achieving consistent cooking results across different zones.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The electric heating components can be dynamically adjusted in terms of power output and operational status (on/off). The heating system can adaptively change heat intensity and activate specific heating zones based on real-time cooking requirements, enabling precise control over heat distribution and cooking consistency.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If chemical fuels are used in grills, then cooking functions are achieved, but fuel supply convenience deteriorates due to the need to add and ignite new charcoal when exhausted

Engineering Contradiction:
Improvefuel supply convenienceVSAvoidtime for fuel replenishment
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The mechanical fuel supply system (charcoal or gas tanks requiring manual refilling and ignition) is replaced with an electric heating system powered by electrical energy. The electric heating components can be continuously supplied with electricity, eliminating the need for manual fuel replacement and ignition processes, thus improving operational convenience and reducing time loss.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If traditional grill structures are used, then cooking functions are provided, but maintaining cleanliness and processing oil stains becomes challenging

Engineering Contradiction:
Improvecleanliness maintenanceVSAvoidoil stains
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The oil collection and removal function is extracted as a separate subsystem from the main cooking structure. Oil stains generated during cooking are collected into dedicated oil collection containers or trays positioned below the cooking surface, separating the harmful oil byproduct from the cooking area. This allows for easier and more efficient cleaning without disrupting the cooking process.

Inventive Principle:
Principle #2Taking out (Extraction)

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

The electric arc grill provides consistent and controlled heat for various cooking functions, improves fuel supply convenience by eliminating the need for charcoal or gas, and enhances cleanliness through efficient oil stain collection and processing.

Implementation Method 1

The electric output head is located below the fire gathering plate, and a gap is formed between the electric output head and the fire gathering plate. Therefore, the fire gathering plate can be heated by the electric arc

Methodology Applied
Scientific EffectElectric arc: Electric Arc

AI summary

The present application pertains to an electric arc grill that integrates a range of components for enhanced functionality. Central to this grill is the electric heating device, which includes an electric heating component and a circuit board integrated with electric components. The electric heating component includes an electric output head and an electric connection rod that is securely attached to and electrically connected with the head, ensuring a stable connection to the circuit board. The grill is equipped with a lifting device that is affixed to and grounded by the grill carrier, facilitating the electrical connection with the fire gathering plate. This plate is positioned above the electric output head, creating a gap that is instrumental in generating the electric arc necessary for heating. The grill enables the fire gathering plate to be heated via electric arc, thereby providing a versatile cooking surface capable of frying, grilling, and baking.
