Current Situation: For the effective presentation in a classroom or in a boarding room using projector, it is required to have minimal or no light in the room. At the same time for students/meeting participants to take notes it is required to have bright light in the room.

Problem: we cannot have bright light and no light in the same room at the same time. It illustrates a situation of physical contradiction.

Q1:  What are the primary desired functions/features of the system?

The primary feature of the system is to have no light in the room for projected images to be visible clearly and also enough brightness in the room for the students to take notes.

Q2:  What is the parameter of the system that you are improving?

I am trying to improve the clarity & visibility of projected images in a classroom as seen by the students.

Q3:  What is the parameter of the system that will be negatively impacted?

To improve visibility of projected images in a class room, brightness of the room would have to be decreased which in turn would make it difficult for students to take proper notes and read from their notebooks.

Q4:  Describe the Ideal Final Result (IFR)

Ideal solution for this problem would be a room with no light when professor is presenting something using projector and the same room filled with bright light when students are writing notes or referring their notebooks.

Q5:  State the Technical Contradictions in both states: (DOI = Direction of Improvement)

Zero light must be present in the room for projected images or screen to be clearly visible to the students.

However Bright light should be present in the room for the students to take notes and read their textbooks.
