Flash of Genius - Part One

One Saturday morning, John and I were driving up to Frederick Maryland to met with a prospective sales agent for Penguin Bottling Company. This 45 minute drive north, we were discussing various ideas and inventions, from the VersaCup to a new idea, an external fire extinguisher for homes. The VersaCup was stuck in neutral, we could not figure out a viable solution for the material to be flexible to hold iPhones to food. A quick Google search on my fire extinguisher for the homes proved that someone else already holds a patent and multiple products on the market. Then about half way into our drive, we turned our attention to the up and coming luau and our pig roster.
This year, we decided that we would not add to the roaster or tweak the unit, however, we opened up the possibility for next year's upgrade. After a few minutes, we re focused our attention on the after party, specifically the cleaning of the pig roaster. We discussed the possibility of adding a pan to the bottom of the pig roaster, so that at the end of the day, rather than having to remove the barrel and dump the unit, we could simply remove the box and dispense the ashes.
We continued to discuss how the Ash Box would function, John suggested the need for removable handles so the heat would not hold us back when we needing to dump the ashes in the morning. And as we discussed these details, we were about 2 minutes away from the meeting location, when John thought, why limit the use to only the pig roaster? Why not use the Ash Box in a traditional gas BBQ? This would convert any existing gas BBQ into a charcoal BBQ, then remove the unit during the week for quick gas BBQ cooking.
After our meeting with the prospective sales agent, we got back into John's truck and immediately we were tossing out ideas on how to get the Ash Box to become fully adjustable, to any size grill. This inspiration and function would not be flushed out today, it would take a week or so and the answer came from the art of origami.
