Human factors and ergonomics is the area of science relating to the relationship between workers, their work place environment, and the equipment used to perform their jobs. This can be as simple as how a person interacts with a PC or as complex as how an automobile assembly worker inserts seats into a car on an assembly line. There are some inherent contradictions involved in the design of such equipment such as displaying of needed information and the mental overload created by the display of too much information. There is the concern about making a pill bottle easily accessible to elderly arthritics and totally inaccessible to young children. These types of contradictions will increase as our population increases and the needs of an elderly population differ from that of a more agile younger population.

TRIZ uses the resolution of contradictions as a key problem solving principle. The various tools and principles used in TRIZ to resolve contradictions can be grouped in many different ways. Two of the most common are separation principles and more specific inventive principles, frequently referred to as “40 Principles”. There have been a number of 40 Principles lists developed over the years, demonstrating the robustness of the original basics of TRIZ: the resolution of design and engineering contradictions. These have included "40 Principles for Architecture", 40 Principles for Food Processing, “40 Principles for Chemical Engineering”, and others. All of these have grouped examples of the application of the TRIZ 40 Principles to a different area of business or technology and continue to demonstrate the robustness of these basic principles as a starting point for simple problem solving. It is possible to group the 40 Principles of TRIZ underneath the broader “separation principles” related to time, space, condition, and parts/whole or system/super-system1. The TRIZ 40 Principles are normally considered when a system is considered to have two different parameters in conflict with each other while the separation principles are normally considered when the contradiction can be condensed into one parameter in conflict with itself. Either approach can yield new thoughts about how to redesign products to improve the human interface.

A tool to estimate the strength and life of a Patent

TRIZ (Theory of Inventive Problem Solving) classifies inventions into five novelty levels. At level 1 are slight modifications of the existing systems.  At level 2 are those inventions that resolve a system conflict or contradiction using usually inventive solution or inventive principle used to solve similar problems in other systems.    At level 3, the inventions change one subsystem or resolve the system conflicts in a fundamental way. At level 4, the invention gives birth to new systems using interdisciplinary approaches. The level 5 inventions are closer to a recently discovered scientific phenomenon. See article for a complete discussion.

Alexander Selyutsky - a key figure in the history of TRIZ!

Alexander Selyutsky

Selyutsky Alexander Borisovich was born April 6, 1933 to an intelligent Jewish family residing in Leningrad. During the World War II the plant where his father was working was evacuated to the Urals, and the family (the parents and Alexander) moved to Chelyabinsk. Here, Alexander graduated from high school. He wanted to go to a military school, but didn’t pass vision test and entered the Chelyabinsk Polytechnic Institute. In his first year he was forced to learn boxing (because of frequent anti-Semitic attacks) and became a Komsomol activist.

After graduation, he was sent to Petrozavodsk Onega tractor plant, where he worked as a designer. He continued leading a very active social life, organized and led voluntary militia patrolling the streets of the city because the situation was very criminal. In the search for more satisfying work he became interested in patenting, completed appropriate courses and became a patent agent.

In 1960, Alexander married Dolly Naumovna Audleys, and had a daughter Alla in 1961. The same year G.S Altshuller published a book " “Learn how to invent"[1] . After reading this book in 1965 Selyutsky wrote a letter to Altshuller. This letter started their acquaintance by correspondence. Since then, Alexander became one of the most dedicated Altshuller’s disciples and an active promoter of the emerging new science.

They finally met in 1968 in Dzintary (near Riga), at the seminar organized by the Central Board of VOIR (state leading inventors’ and innovators’ society) that invited Altshuller and several of his associates. It was the first time that Alexander and others got a chance to work under the direct guidance of Altshuller and to learn from him. Later, in 1983, Alexander participated as one of the instructors in the seminar conducted by G.S. Altshuller in Moscow at the Institute for continuous education for chemical and petroleum industries.
