Solution Overview
Problem
Charcoal grills pose risks such as carbon monoxide poisoning, fire hazards, burns, inhalation of particulate matter, and chemical exposure due to improper use, and while grilled food is appealing, these risks need to be minimized for safe and enjoyable cooking.
Innovation Solution
A barbecue grill apparatus with folding plates, rotating connectors, and electrical heaters, where the heaters emit heat through meshes and are controlled by a temperature sensor to ensure safe operation, and the design allows for easy storage and use in a well-ventilated area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If charcoal is used for grilling, then smoky flavor and high heat are achieved, but carbon monoxide poisoning and fire hazards occur
Solution Approach 1:
The patent extracts the harmful combustion process (charcoal burning) from the heating function. Electrical heaters replace charcoal as the heat source, eliminating carbon monoxide production while maintaining the high heat necessary for grilling. The heating element is separated from the harmful byproducts of combustion.
Solution Approach 2:
The patent substitutes the mechanical/chemical combustion system (charcoal burning) with an electrical heating system. This replacement eliminates the production of carbon monoxide and other harmful emissions while providing controlled heat for grilling through electric heating elements.
2Temperature
If charcoal is used for grilling, then intense heat is produced, but fire hazards and burns increase
Solution Approach 1:
The patent replaces the uncontrolled chemical combustion of charcoal with controlled electrical heating. The electrical heaters provide intense heat when needed but can be precisely controlled and turned off, eliminating the uncontrolled fire hazards associated with charcoal combustion.
Solution Approach 2:
The patent incorporates temperature sensors that provide feedback to the control system. This allows the heating elements to be automatically regulated, turning on when temperature drops and turning off when the desired temperature is reached, preventing uncontrolled heating and fire hazards.
3Ease of operation
If traditional grill design is used, then grilling function is achieved, but storage space is excessive
Solution Approach 1:
The patent applies nesting by placing the heating elements inside the folding plate structure, and by designing components that can be stored within each other when not in use. The folding plates can be collapsed and nested together, minimizing storage volume while maintaining full grilling functionality when deployed.
Solution Approach 2:
The patent uses dynamic folding plates that can transition between extended (grilling) and collapsed (storage) states. This dynamic structure allows the grill to adapt its volume based on usage needs, providing full functionality during operation and minimal storage space when not in use.

Function Achieved in This Case
The solution provides a safe and convenient way to grill food by minimizing risks associated with charcoal use while maintaining the flavor and texture benefits of traditional grilling, offering a safer and more controlled cooking experience.
Implementation Method 1
a first heater placed in the first middle part to emit heat toward the grill bracket
Implementation Method 2
far-infrared reflecting material is applied on inner side of the first folding plate and the second folding plate

AI summary
A barbecue grill apparatus includes a first folding plate, a second folding plate, a rotating connector and a first heater. The first folding plate has a first top part, a first middle part and a first bottom part. The second folding plate has a second top part, a second middle part and a second bottom part. The rotating connector connects the first bottom part and the second bottom part for the first folding plate and the second folding plate to rotate along the rotating connector to spread with a first angle to be an open mode and to rotate along the rotating connector to collapse with a second angle to a close mode. In the open mode, a grill bracket is placed between the first folding plate and the second folding plate. The first heater placed in the first middle part to emit heat toward the grill bracket.
