A single function model that replaces the original substance-field formalism. Cleaner, more general, and translatable across mechanical, chemical, electronic and software domains alike.
We are a small Seattle firm of TRIZ practitioners working alongside the engineers and scientists who build aircraft, semiconductors, materials, and medical devices. Our method — TOP-TRIZ — is the most complete modern reformulation of Altshuller's theory of inventive problem solving.
TOP-TRIZ is Z. Royzen's reformulation of Altshuller's TRIZ — the same physics-grade rigor, condensed into a clear flowchart and a single shared vocabulary. It is the version we have used to train inventors at Boeing, Saint-Gobain and Bridgestone for three decades.
A single function model that replaces the original substance-field formalism. Cleaner, more general, and translatable across mechanical, chemical, electronic and software domains alike.
From problem formulation through ARIZ, root-cause analysis, ideal ways and direct ways — every step is part of a single coherent flowchart your team can run together.
The promise is concrete: if a solution to your contradiction exists, the method will surface it. Course alumni hold patents, win invention awards, and lead corporate workshops of their own.
Five live, instructor-led programs taught online from Seattle. Begin with the free webinar; advance through certification at your own pace. All cohorts are taught personally by Z. Royzen.





Selected from three decades of correspondence with our students and clients — Boeing Associate Technical Fellows, Saint-Gobain senior scientists, university faculty.
The TOP‑TRIZ algorithm is complete. If a solution to your challenge exists, you will find it.
The most useful, the most stimulating and the most satisfying training of my career in engineering.
A no‑compromises way to employ the full power of classical TRIZ — without all the down time to learn it.
A practical tool for solving all types of engineering, scientific and business problems. Highly recommended.
Royzen has made TRIZ more coherent and easier to use — and easier to integrate with other engineering disciplines.
For three decades we have been called in by R&D leaders to formulate the contradictions inside their hardest problems and to surface the inventive solutions hiding inside them. Engagements range from a single afternoon workshop to multi-quarter embedded practice.
Our consulting work has helped clients save hundreds of millions of dollars, win new orders, improve product reliability and protect new directions with patents.
