Your main emphasis in development of products should be to reduce risk and allow people to see the benefits of the invention.There are several stages in the path to becoming a product that can be sold commercially.
First is the “idea” stage. The idea is roughly defined. You want a “Widget” that performs some function and has certain properties. The product does “this” in “that” way.
Next is “developed idea” stage, where materials, specifications, all relevant specifications are quantified and modeled. Development often includes making CAD models or product prototypes. With the documentation that is made at this stage, one can quote tooling, and manufacturing costs accurately. With prototypes, you can test your product concept (and usually refine it).
Next is “Prototype or small lot manufacturing” stage. You usually are looking for manufacturing problems. Before committing to large volume and cost tooling and final development, it is invention help conservative to test your idea in small volumes. This allows other people to evaluate your idea and suggest changes. This also identifies the tradeoffs between product function, product cost, and product specifications.
At the end of this stage, you have a tested, manufactured product. You must decide whether to approach a major company with your idea for distribution and/or manufacture or to manufacture and sell the product yourself.
Last is the “Product ” stage. At this point regulatory and legal issues are addressed. Quality specifications are established. Product costs are known. The product can be manufactured and sold.
Next, your attention should shift to sales and distribution issues. What is the best way to bring this product to market? Is it complimentary to some existing products or procedures? Is it better to go it alone or partner with established distributors? Who would use the product and why?
A typical manufactured product has 40-60% gross profit. If it sells for $10, it costs between $6 and $4 to make (materials, labor, packaging and direct manufacturing overhead).
Why? Risk Reward! An invention starts as an idea of how to provide some new benefits. When the idea is “sold” or “licensed” to a major company as an idea, it is worth less to the company. This is because it is “risky”. The product may not work. It may cost more to manufacture than the end user is willing to pay for the derived benefit. The company must spend money to make prototypes to test the idea to prove its effectiveness and understand the manufacturing problems. The product may be difficult to manufacture. If the inventor does not believe enough in his/her invention to invest their money, why should the company? For 100 ideas submitted to a company, one may be worthy of development each year.
