How to make Money from Your IDEAS and Inventions

Step 3 Design a method for manufacturing

Now that you have built a simple prototype of your device and tested it, you have to figure out how to make thousands of that device very quickly. An easy way to decide on the best manufacturing method is to use flow charts. Figure out the path of every component you plan to use from the raw materials to the packaging. Next figure out each process that take the components from one step to another, (soldering, gluing, .etc). Now you can attach price tags to each component or process. Time yourself going through each process, take the average of these times and divide by 60 minutes, then multiply by minimum wage(about $7.50). this gives you the aproxamite price per action on each device. Now to Optimize you must look at multiple routes that you can use and find the absolute lowest cost with the highest volume.

For Example It took me over 4 Hours to build the first zapper. After optimizing my design, i reduced the time down to 3 minutes when built by a mentally retarded person.

Initially I built a bunch of zappers and recorded all the steps i went through. then i timed each motion. Using flow charts and gant charts i tried to find and eliminate the slower steps in construction. I optimized production by reducing multiple actions into 1 swift motion. I also built tools and machines like a small plastic extruder and crude injection molds to help speed up production. Unfortunately i failed to finish everything when i left for college so my extruder and more complex machines are on hold till Christmas.
