Inventors often start their idea for an invention with a question, a hunch, or a doubt. These are all valid ideas for an invention, and many of the most successful ones begin with one. These are known as the "three D's" of invention development. Having one of these three is the key to creating a successful business. The next step in creating a successful invention is to test it with real consumers. Test groups can be useful in generating ideas, and entrepreneurs can also trademark their business name.
Questions

As a first-time inventor, you might be wondering what the best questions for an idea for an invention are. It can be difficult to know how to approach the process, and you may have difficulty digging up answers to your questions. In any case, the answers to the questions will be helpful for the creation of a detailed description of your product or invention. If you are not sure what to ask, consult with an experienced inventor. You can use the following steps to guide you in the creation of an excellent invention.
Hunch

Despite the hype, few great ideas come as a single flash of inspiration. In most cases, they are a conglomeration of many smaller hunches that eventually 'collide' to form a big idea. In fact, Johnson attributes the increase in innovation to the increase in connectivity between people. Connectivity enables people to exchange ideas, share knowledge, and find complementary information. Here are a few examples of hunches that were triggered by the same situation.
Inventors start with a hunch or a hunch

Often, an inventor will begin the invention process by having a hunch or an idea. Inventions are often the result of an idea or a concept that comes to them during a random time of day, such as when you're sleeping. It can also be the result of a eureka! moment, where an idea just pops into your head when you least expect it. This has been true for many popular inventions, including Velcro, Post-it Notes, and even potato chips and chocolate chip cookies.
Prior art

When searching for prior art for an invention, you should consider referring to the patent database of the invention's category. Patent databases cover more than 130 million documents in some cases. They're organized according to the subject of the invention and are therefore extremely valuable resources. Aside from patent databases, there are also other databases that provide valuable information. These include trade journal articles, data books, catalogs, public discussions, and exhibitions.
Refine your idea

Before you can refine your idea for an invention, you must define the parameters of your idea. It can take the form of a product concept, a project plan, or a business case. Each step in the process should be evaluated critically and from multiple points of view. The feedback you get will serve as a reality check and point out obvious issues or assumptions in your idea. After you have identified the parameters of your idea, you must decide which ones to refine and which to put on hold.
Turn it into a prototype

Having a crude prototype of your invention is one of the best ways to test the basic premise of your idea. Even if you don't have any money to build a working model, it can help you to think through the main idea of your invention before moving on to the next step. Include a description of your invention and a drawing or two to illustrate its most important features. This prototype should serve as a rough guideline for figuring out what makes your invention unique.
Bring it to market

In order to bring it to market, you need to understand the basic tenets of the product. This means doing preliminary market research. This will allow you to understand whether there is a demand for the product or service and what your competition might be. Besides, it will help you define your potential customers. It is always best to understand the competition in your market before bringing your product or service to it. Then, you can choose the best way to bring it to market.
