Innovation engineering — Conceptualization

How to create a concept

So far we’ve created a function description, list of requirements, possible solutions for each function, and prototypes. Now is where it all comes together. Each function will need to be fulfilled, and the possible solutions are how they can be fulfilled. A morphological chart is a nice way of representing all these visually. Each function is listed on the left side, top to bottom, the right side of the table shows each possible solution for each function. We then simply draw lines from top to bottom, connecting different solutions to create a concept. Sounds simple, right?

How to draw lines

Each line drawn will create a concept that will need a more in-depth description, some solutions might not combine with others. Creating the concepts takes work, and the lines are simply a visual representation of this work. Each concept will need to have a clear motivation, which comes from your mission. If your mission states cheapest, lightest, biggest, your concepts will have to be created keeping this in mind. For instance, creating a concept which focuses on the cheapest solution for each function, will likely yield a product with the lowest possible cost. It is a good idea to create 3–5 concepts, no more, no less. This will give you enough freedom to choose the best solution, and limits the amount of research and work to create the concept descriptions.

Creating the concepts

The concept will be a complete description of how the concept would work, and provides all the information available to test it against as many requirements as possible, preferably all. This includes drafts of visual design, schematics, flowcharts, or algorithms. If you are missing information in certain areas, go back to researching or prototyping. This is the last step before heavily investing in development, so it is important to get it right.

Choosing a concept

Your requirements are what your product or idea will have to do. Your concept should be tested against every requirement to make sure you solve every problem and tackle every challenge. We already did this to all the solutions, but combining the solutions might create new problems. All solutions on their own might fit easily within your specified maximum volume, but combining them might create a behemoth, far outside of your dimensions. Some requirements can have an added success criterium. For instance, the product should cost less than XX, creates a success criterium “cheaper is better”. In the unlikely scenario where you have multiple concepts that tick all of the requirements’ boxes, your success criteria will guide you in choosing the best solution.
