Theory of inventive problem solving (TRIZ): Case study

Abstract

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.
