Let he who has never had a brilliant idea, yet didn’t know how to bring it to life, cast the first stone… Let’s assume you are like me, the kind of person who has lots of ideas going through his head. If this is indeed your case, you probably sometimes wonder how to realize them. If so, keep reading! You may find some help in the following lines.
We will talk about the main process we use at our start-up company,, O’SOL, to rapidly shape an idea at a low cost. The emphasis will be put on mechanical prototyping. The methods described are the ones we use on a daily basis to create parts, and are the exact same methods we used to develop our mobile photovoltaic generator.
First of all, let’s go back to the main term of this piece of article : the prototyping. What is it? What is its purpose?
Prototyping is the process which makes an idea or concept into a physical representation which can have multiple objectives:
In some cases, the main goal will be visual. Prototyping is then a way to find the right design, and in some cases it can serve as a demonstration.
On the contrary, in other cases it can be a method used to (in)validate a concept or a functionality, as it can allow you to easily identify flaws in a concept or demonstrate some functionalities (assembly, interlocking…).
Finally, late the in development cycle there is a phase named “technological prototyping”. This terminal phase is as close as possible to the final product (same shapes, materials…) and allows the complete validation of a product (advanced thermal and mechanical studies, real-life tests…).
The need has to be the heart your product’s development. Brainstorming is a powerful tool for this. Start by writing down a list of all the ideas which meet your needs and your constraints on a sheet of paper, a whiteboard or any support you like. Even though some of them may seem like stupid or far-fetched: write them down! Considering them could lead you to a better idea… The creativity process is long and self-sustained: the more ideas you think, the more new ideas will come to you.
Once your list is drawn-up, take a moment to free up your mind. Play some sports, go for a walk, watch some funny videos on the internet or work on other things. You will go back to your ideas in a few hours or the following day with a more critical spirit. When going through your ideas, ask yourself these important questions: Which ideas seem good at first sight? Which seem complicated / too long or too costly to develop? Which ones seem easy to try?
It is now time to pick 2 or 3 of the best ideas and develop them using some of the tools of the prototyping process in order to get a physical part.
A multitude of tools can help you get from an idea to a prototype. We already talked about brainstorming, and drawing. Listed below are some of the tools we use on a daily basis at O’Sol:
Another fundamental notion (if not the most important one) to be introduced is the iterative process. As described in our 3D printing article, this process makes us accept mistakes as an integral part of the development process. The infographic below lists some of the prototyping steps and tools used at O’Sol as part of our iterative process.
Typically, we start with a brainstorming session to get a nice list of ideas. We study them to select the best ones, which we later transpose as a virtual CAD model. When possible, we print the parts in 3D to test its functionalities or its implementation in an assembly. Then we sit around a table again, and if the product isn’t perfect (and it rarely is on the first try), we list the issues and do another brainstorming session to identify potential solutions which we later develop. We repeat this process until we have a finished product.
