A short paper by Kalevi Rantanen shows how to combine the principles of universal design and 40 Principles of TRIZ. It gives another perspective on how to apply the principles of universal design in a problem solving context. TRIZ is the Russian acronym for “Theory of Inventive Problem Solving”.
The title of the paper is, “Homes for Strong Families, Children, Seniors and All Others. How Universal Design, Design for All and Forty Principles of TRIZ Enforce Each Other”.
The 40 Principles of TRIZ are a list of simple, and easy to learn rules for solving technical and non-technical problems quickly and simply. Studying these existing solutions can inspire people to solve new problems and imagine innovative solutions. They show how and where others have successfully eliminated contradictions. They take us to the proven, powerful recorded solutions contained in the patent database. These 40 Inventive Principles help solve both technical and non-technical problems.
Principles and something more
The paper begins with a note about accessibility being a “must”. In TRIZ jargon accessibility is one feature of the Ideal Final Result. It’s about a check between whether a feature reduces harm for one group without increasing harm for another.
“For example, we consider removing a threshold. A harmful feature, a barrier to the user of a wheelchair or walker disappears. Are the useful features retained? Perhaps even new benefits appear? Everything useful is retained if we move thresholds. A new benefit is that it is easier to clean doors.
Will new harmful features appear? Usually not, but some doors may need sealing. In that case flexible, rubber-like thresholds can be used. Does the system become more complex? No, removing thresholds makes a building more simple.”
