Barbecue comprising one or more grills
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing barbecues face challenges in achieving homogeneous cooking, are bulky and complex, and require manual rotation of food holders, leading to inefficiencies and increased manufacturing costs.
Innovation Solution
A barbecue with a compact, triangular-shaped grill that rotates automatically, featuring a frame to collect juices, a handle for ease of use, and a modular design with removable fuel containers, along with a motor-driven mechanism for seamless food cooking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a circular rack with toothed wheels is used to rotate skewers and a circular grill, then food can be cooked, but achieving homogeneous cooking is difficult because the circular grill can only be turned manually by temporarily lifting the skewers
Solution Approach 1:
The circular grill is divided into multiple triangular grills arranged radially around the central axis. Each triangular grill is an independent cooking unit that can be rotated individually by the motor-driven mechanism, allowing simultaneous and independent rotation of multiple food items for uniform cooking on all sides.
Solution Approach 2:
The motor-driven mechanism automatically rotates each triangular grill about its own rotation axis, eliminating the need for manual intervention. The system performs the turning operation autonomously, ensuring homogeneous cooking without requiring users to manually lift skewers or turn the grill.
2Productivity
If two grill panels with toothed wheels and extensions are used to support the grill in a rotatable manner, then food can be cooked, but the barbecue has a relatively large surface area and constructional complexity in proportion to the amount of food that can be cooked
Solution Approach 1:
The grill system is segmented into multiple triangular grills that can be arranged radially around the central axis. This segmentation allows the barbecue to cook multiple items simultaneously in a compact circular footprint, increasing productivity without proportionally increasing the overall surface area or structural complexity.
Solution Approach 2:
Multiple triangular grills are merged into a single integrated circular barbecue structure sharing a common heat generator and control mechanism. This merging reduces the overall surface area required compared to separate grill units while maintaining the ability to cook multiple items simultaneously, and simplifies the mechanical transmission by using a centralized motor system.
3Ease of operation
If two grill panels with extensions are used to support the grill, then the grill can rotate, but each grill cannot easily be mounted in a projecting manner like the skewers due to its weight and size
Solution Approach 1:
The grill structure is divided into lightweight triangular sections that can be individually mounted and rotated. Each triangular grill is a smaller, more manageable unit compared to a full circular grill panel, making it easier to handle, mount, and position despite the overall system capacity.
Solution Approach 2:
The triangular grills are arranged radially in a circular pattern around the central axis, utilizing the vertical and radial dimensions efficiently. This dimensional arrangement allows the grills to be mounted in a projecting manner similar to skewers, with each triangular grill positioned at an angle to maximize space utilization and ease of access.
