Abstract :  

Human factors and ergonomics is the area of science that applies to the physical, perceptual, and cognitive interactions of people with things, systems, and environment. This can be as simple as how a person uses a tool or as complex as how an operator manages the control room of a nuclear power plant. There are some inherent contradictions involved in the design of systems 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 are increasing because of factors such as our population becoming more elderly (their needs differ from that of a more agile younger population) and products/systems becoming more feature rich and complex. 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.  Recently, 40 Principles for Human factors and Ergonomics were published in the TRIZ Journal. This presentation will update this publication with examples of TRIZ principles and the use of separation principles to resolve conflicts in product designs that relate to human factors. A participative case study will also be used in the presentation.

Case Studies From A Breakthrough Innovation
"Starting in August 2004, the Hong Kong government began sponsoring a deployment of TRIZ to a cluster of eight local companies. Over the course of the next 15 months, each company was invited to assemble a team of between 5 and 8 engineers and designers each of whom would be exposed to a series of six three-day TRIZ education and utilization sessions. The aims of the program were for each company to realize new products, patents and tangible financial benefits, and to measure the extent to which TRIZ allowed companies to accelerate their rate of innovation. This paper describes a collection of some of the success stories emerging from the program."

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.
