The modern Theory of Inventive Problem Solving TRIZ (VDI 4521) contains 40 basic Inventive Principles (IP). These principles are simple to use or modify and can be easily integrated in brainstorming or daily engineer’s work. One established part of industrial practice is the composition of the specific groups of principles for solving different kinds of problems (Livotov, Petrov, 2011). Based on interdisciplinary experience of TRIZ application in the industrial companies in the last 25 years the a general order in the application of 40 Inventive Principles can be recommended for idea generation and problem solving (Livotov, Chandra, Mas'udah et al, 2019). This brochure presents an update of the 40 Inventive Principles extending the original version (Altshuller, 1984) with additional 70 sub-principles, resulting in the advanced set of 160 sub-principles, regarded as elementary inventive operators. These extended version of inventive principles finds its application in the AIDA Automatic IDEA & IP Generator https://www.tris-europe.com/eng/software/innovationssoftware.htm…
