Anybody who has ever read the Altshuller books knows that he subdivided all inventions into five levels, and that TRIZ was aimed at helping solve problems of the higher levels, not at toilet improvements. However, the case studies published in the so called TRIZ-journal for some reason very often feature "power" of TRIZ specifically on toilet inventions.
Consider, for example, the latest issue of the TRIZ-journal. Of 3 case studies it presents, one is of a toilet flavour . Another one  is a second-level invention, which does not require TRIZ at all. And the third one  is also not a case study on application of TRIZ ! It is rather a case study on how to advance your career if you are good for nothing but are lucky enough to learn about TRIZ before your colleagues.
The technology is very simple. You just start pitching TRIZ to your superiors as a magic tool of solving all problems in your organization. Since the problems were in place for a long time and nobody was able to solve them, and you offer a new as yet not tested cure, the management has little reason to resist you. You become a TRIZ prophet in your organization until the bubble bursts, and you find yourself on the street. But in the past the entire process usually took a few years, during which you briefly occupied a low level management position and made good money. Thus, when you find yourself out of work, you will be able to survive by establishing you own consultancy and by writing books where you will describe your past TRIZ feats and how your previous employer benefited from them.
Apart from the case studies just reviewed, the July issue of TRIZ-journal also contains 2 book reviews, 1 conference report, 1 TRIZ teaching experience report, and 1 appeal to the TRIZ community to help in solving a chalenge (which normally passes without a response).
Of all this garbage, the only article deserving attention, is a review of the book "Creativity in Product Innovation" by Jacob Goldenberg and David Mazursky. The reviewers (E. Domb, M. Slockum, and G. Rawlinson) rebuke the authors for "the lack of credit to the originators of many of the concepts" as if they do not suffer from the same disease. Indeed, why should Jacob Goldenberg and David Mazursky have credited Mr. Horowitz (as the reviewers suggest) if Mr. Horowitz himself have not credited the Russian Jewish emmigrants to Israel from whom he borrowed (and who in turn did not cite the real authors too). If the reviewers want to "expropriate expropriators", then I would recommend them to start with themselves.
