Solution Overview

Problem

Existing barbecue racks have low utilization efficiency due to the irregular shapes and sizes of foods, which leads to inefficient use of space and potential flavor mixing when different foods are stacked together.

Innovation Solution

A rack design featuring a limit plate with multiple limit notch grooves, supports, and a rotating component that allows for independent placement of irregularly shaped foods, optimizing space usage and preventing flavor mixing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If foods are piled up on each other on the rack, then the rack can accommodate more foods, but the utilization efficiency of the rack is not high due to irregular shapes occupying excessive space

Engineering Contradiction:
Improvenumber of foods accommodatedVSAvoidspace utilization efficiency
Core Design Contradiction:
Quantity of substanceVSVolume of moving object

Solution Approach 1:

The rack is divided into multiple independent compartments, each capable of holding individual food items. This segmentation allows irregularly shaped foods to be placed in dedicated spaces rather than requiring excessive clearance, thereby improving overall space utilization while maintaining the ability to accommodate multiple food types.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The rack structure utilizes three-dimensional space more effectively by creating vertical and horizontal compartments. Foods are arranged in multiple layers and sections, transforming a single-plane placement into a multi-dimensional configuration that maximizes the rack's volume capacity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If various foods are placed together on the rack, then the rack serves multiple food types, but flavors may mix between different foods

Engineering Contradiction:
Improvefood type accommodationVSAvoidflavor mixing
Core Design Contradiction:
Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The rack is divided into multiple independent compartments, each capable of holding individual food items. This segmentation allows irregularly shaped foods to be placed in dedicated spaces rather than requiring excessive clearance, thereby improving overall space utilization while maintaining the ability to accommodate multiple food types.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Each food item is extracted and placed into its own dedicated compartment or section of the rack. This separation extracts foods from a common space and isolates them individually, preventing flavor mixing while maintaining the rack's versatility for holding various food types.

Inventive Principle:
Principle #2Taking out (Extraction)

3Device complexity

If a simple rack structure is used, then the device complexity is low, but the space utilization and food stability are insufficient

Engineering Contradiction:
Improverack structure simplicityVSAvoidspace utilization
Core Design Contradiction:
Device complexityVSVolume of moving object

Solution Approach 1:

The rack is divided into multiple independent compartments, each capable of holding individual food items. This segmentation allows irregularly shaped foods to be placed in dedicated spaces rather than requiring excessive clearance, thereby improving overall space utilization while maintaining the ability to accommodate multiple food types.

AI summary

Disclosed are a rack and a barbecue grill. The rack includes a limit plate and two supports connected with the limit plate. The limit plate is provided with a plurality of limit notch grooves, and the plurality of the limit notch grooves are arranged along a length direction of the limit plate; the limit notch grooves are configured to pass through the limit plate. The present application aims to improve the utilization of space by gathering some small handle-shaped irregular foods by using a rack.
