how to do by using inventive principles number 35. parameter change

Think of a problem and define it clearly using TRIZ CECA, Functional Analysis, focus on the harmful/inadequate function through su-field; then provide solution using the TRIZ concepts and tools either of trimming and/or engineering contradiction with the 40 Inventive Principles, and/or others. Get inspired by doing a function-oriented search. Check the quality of your solutions from s-curves and see how the main parameter value evolves. Then, prepare a presentation that discussed about the problem you are solving and how you arrive to the solution
