Concept of Problem, Motivation and Contribution in research  The following example will help that I wrote from my practical experience as PhD fellow.  This topic is written on 7 October 2022 when I am changing color of all rooms in our flat. Problem: The problem is what you are going to investigate.  This usually narrows down to: (a) it would be useful or (b) it would fill in an area of knowledge. For example: Problem: I want to change the bedroom color from ocean blue to light yellow.  Motivation:   The motivation is why.  This usually narrows down to: (a) it would be useful or (b) it would fill in an area of knowledge. For example: My bedroom has an ocean blue color from 10 years back. Now it is out of choice. It would be a more innovative choice to bring color change to light yellow using the Berger color bank machine. This would enhance the brightness inside the room, and increase mind satisfaction.  Contribution: List of obtained interesting results from the research. For example:
