Theory of inventive problem solving (TRIZ): Case study

TRIZ comes from the Russian acronym of the phrase Theory of Inventive Problem Solving ("Tieoriya Riesheniya Izobrietatielskij Zadach" or Теория решения изобретательских задач). This theory for solving problems and projects invention was developed by the Russian inventor Genrich Altshuller and his colleagues since 1946. This methodology is based on the belief that there are universal principles of the invention, which are the basis for creative innovations that assist in the advancement of technology. Depending on the amount of data and the availability of data analysis methods, problems can be classified as structured, semi-structured or unstructured. Structured Problems are those whose solution depends on a single series of steps. The data set is known and a known sequence, a structured data identical problem will always have the same solution must be followed. In unstructured problems there is not an algorithm that ensures to reach an optimal solution, either because there is insufficient information on the factors that affect the solution or because there are many potential factors, which can not be formulated with any algorithm that guarantees a unique solution is correct. Actually, TRIZ improves the methodology for problem solving structured by applying its principles to the early stages of conventional structured methodology more creative and advanced measures that make the resolution process more efficient and effective, also this methodology can be applied to unstructured problems. In this paper, an analysis of the methods of TRIZ Theory is made and two case studies are addressed through this methodology.
