Consider the instance of a step-by-step execution of ARIZ-85v on the example of the problem of transporting slag (see http://www.altshuller.ru/triz/ariz85v-p1.asp for details). Specifically consider steps 1.6 and 1.7.
Then on Step 1.7 it is said that the problem is easily solved by applying Standard Solution 1.2.2. The Standard Solution says that the sought for X element could be a mixture (or a combination) of the elements identified on Step 1.6. In this case it is a mixture of slag and "no-cover", i.e. a mixture of slag with nothing. Would not the result be slag again ?
The example does not answer what the result of mixture of something with nothing could be. It only says that although the problem is easily solved by the Standard, let's skip its application and proceed with search for X-element by the algorithm. So, let's skip it, as in fact it does not provide any clue.
The next step 2.1 says that the space previously occupied by the cover is now empty. But Step 2.3 already asserts that "no-cover" is air in this empty space. How and why the empty space turned into air is not explained. It is considered to be self-evident. But it is not. Does empty space always turns into air ? Not at all.
To bridge the gap in the logic of the algorithm I propose the following meta-algorithm for steps 1.6 through 2.3:
