Me and my friends went to a beach last time to make a bonfire and cook some food. After we dug the sand out to put the wood in and lit up the fire, we prepared to cook our corn, chicken, and s'mores. We wrapped our food inside aluminum foil and then put them around the fire. We ended up using a lot of aluminum foil and all of it went to the trash. My solution is a small and light bonfire grill that could be collapsed and carry along.

Features:

Weight less than 7 lbs
Material is casted steel for durability
Easy to pack and set up

Step 1: Market Research

There are some bonfire grill products already in the market. Even though they are more compact and easier to put inside your bag, they are not designed to cook an adequate amount of food for a small group of 4. My grill design will serve up to a group of 4 to 10 people. From s'mores to barbecue sticks, its large grill section could handle up to 15 pounds of food.

Step 2: 3D Modeling & Rendering

Design the exterior frame with fillet for rounded corners
Design the crossing bars inside the frame
Design the handle for users to carry
Design the four rotating legs
Render the model with casted steel appearance

Step 3: Details

This bonfire grill has 4 legs that could be fold it up inwardly to carry away. The legs have circular rotational joints that could be rotate to any angle to adapt to the uneven surface of the sand. Each leg bottom is designed to dig into the sand to increase stability of the grill and support even more weight. The tolerance of the leg joints is reduced to the minimum to ensure that the legs could support the grill when opened and stay in place when closed.

Step 4: Completed Product

I am really proud of this design and I want to make this digital design into an actual product later using metalworking tools. Going to the beach next time and cook food with this grill would be so much easier. I had a chance to upgrade my Fusion 360 Design skill to actually design a usable product with this contest. I will look to participate in more contests like this one to improve my skill.

Looking back at my design, I would like to add 4 round slots in the lower side of my grill to hold the four legs in place once they are closed.
