Go to the [url removed, login to view] website and experiment selecting a feature you want to improve and a feature you do not want to worsen (use the Interactive TRIZ Contradiction Matrix on the right side of the main page).
Write a ten to fifteen page paper, select two different problems from your own experiences. Describe both problems, the improving principle and the principle that you do not want to worsen. Identify what the contradiction matrix identified as suggested principles, and describe each of the principles and if you think they helped guide you to a good possible answer to resolving the contradiction.
