Concrete realization refers to the concrete embodiment of your technical scheme. If your technical scheme is structural and has many manifestations, you can use the example 1\2\3 to express it. No problem, I recommend it.
However, if your technical solution is structural, there is only one form of expression, but there are many ways to use it. In fact, there is only one embodiment, but you can explain several usage methods after the description of the embodiment is completed.
However, if your technical solution is to use the process, it is completely right.
