Grill
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smokeless grills have a single function and low energy utilization efficiency, as they only grill food under the heat source, wasting heat in rising air and requiring inefficient energy use.
Innovation Solution
A grill design with a grill assembly below the heating assembly, an iron plate assembly above, and a reflective structure covering the heating assembly, which reflects heat to both assemblies, enhancing heat utilization by conducting heat through contact and air circulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the heat source is placed above the food to avoid oil dripping and smoke production, then smokeless grilling is achieved, but heat utilization efficiency decreases because heated air rises and cannot heat the food below
Solution Approach 1:
The patent introduces a reflective structure (mirror) above the heating assembly that redirects heat in the vertical dimension back downward to the grill assembly. This creates a multi-dimensional heat distribution system where heat can travel upward, reflect, and then descend to heat food on both upper and lower surfaces simultaneously, resolving the contradiction between smokeless operation and heat utilization efficiency
Solution Approach 2:
The reflective structure acts as an intermediary element that captures rising hot air and redirected heat, then channels it back to heat the grill assembly and food from above. This mediator enables the system to maintain smokeless operation while improving heat utilization by redistributing the rising heat to where it is needed
2Object-affected harmful factors
If a single heat source configuration is used for smokeless grilling, then smoke production is reduced, but the device can only perform one cooking function
Solution Approach 1:
The patent designs the grill with dual cooking surfaces (upper iron plate assembly and lower grill assembly) that can simultaneously perform different cooking functions. The reflective structure enables both surfaces to be heated effectively by the same heat source, allowing the device to function as both a smokeless grill and a teppanyaki cooker, thereby achieving multi-functionality while maintaining smokeless operation
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 grill achieves smokeless grilling and teppanyaki simultaneously, improving heat utilization by reflecting heat to both grilling and iron plate assemblies, reducing heat dissipation and enhancing energy efficiency.
Implementation Method 1
Since the upper area of the heating assembly is also covered with the reflective structure, the heat is reflected to the grill assembly underneath the heating assembly through the reflective structure
Implementation Method 2
heat can be conducted to the iron plate assembly from the reflective structure through the contact therebetween to heat the food on the iron plate assembly
Implementation Method 3
because the air will rise after being heated, the heat in the rising air cannot be used to heat the food below the heat source

AI summary
A grill, including a support assembly, a grill assembly, an iron plate assembly, and a heating assembly. The grill assembly, the iron plate assembly, and the heating assembly are mounted on the support assembly. The grill assembly is located below the heating assembly, and the iron plate assembly is located above the heating assembly. A reflective structure is covered over an upper area above the heating assembly, and the reflective structure is in contact with the iron plate assembly. The upper area of the heating assembly is covered with the reflective structure, and the reflective structure is in contact with the iron plate assembly. Heat is reflected to the grill assembly underneath the heating assembly. As the reflective structure also absorbs heat, thus the heat can also be conducted to the iron plate assembly through the reflective structure to heat the food on the iron plate assembly.
