Vending Mahcine for Selling Canned Food.

I was 25 years old when I approached my boss with the idea, and he agreed to fund the prototypes. In return, I promised to share the potential profits. The main task was to make it extremely cheap and easy to assemble, with the goal of being able to produce 2-3 machines per day at a cost cheaper than $1000. It took me two years of experimenting to find suitable solutions and complete the project. From the standpoint of the task at hand, it was a success. The prime cost of the machine was only $800 (and I believe it could be even less if produced in larger quantities). The entire apparatus consisted of sheet parts cut on a laser cutting machine and various standard components. For example, the main driving motors were from Lada’s windshield wipers, which were readily available in large quantities and very inexpensive due to mass production. Experimentation showed that they were durable enough for the task. There wasn't a single non-standard part that had to be machined on a lathe or milling machine. So, after purchasing all the necessary components, assembly was simple, requiring only four walls, a roof, and a set of standard tools.
