Charcoal Stove: Step 1 - The Design Process

For our final project we have been asked to design a better charcoal burning stove. Our first step in the design process was a speed round of sketching. We each drew multiple quick sketches, each of us introducing or highlighting features we thought might be important. 

Sketch 1: A bottom fueling, raised, square form with chimney. Single temperature.  

Sketch 2: A bottom fueling, raised, square form tapering top. Single temperature. Grates inside of tapering top. Handle attached- for easier transport.   

Sketch 3: A bottom fueling, rectangular form . Dual temperature- side sectioned heating.  

Sketch 4: A bottom fueling, raised, square form with a side chimney. Dual temperature created by layered heating concept. High heat on bottom with access through tray. Low heat on top with open cook top area. 

Sketch 5: A bottom fueling, raised, square or circular form. A metal base with a ceramic cooktop pot concept. Single temperature.  

Sketch 6: A bottom fueling, raised form with disconnected extractor. Grate over open flame. No chimney. Single temperature.  

Sketch 7:  A multi-layer/multi-fuel tray stove. Not cooking over open flame. An oven style stove.  

Sketch 8: Fuel in center of stove. Small trays on either side of the fuel creating a 'heating space' or small oven. Top layer cook stove. Fuel moves upward to heat the cooktop. 

Sketch 9: Simple rectangular form with high heat low heat variation. Fuel inserted into the central area or off to the side allowing for cooktop temperature variation
