Vapor

With application of a centrifuge force, the vapor can be separated, then we
need to add an action, or a field, which is “centrifuge force,” and a subject,
which is a rotation device, to make a complete subject-action-object model:

Rotation Mech
Device Vapor

where “Mech” stands for mechanical field or mechanical action.

Method 2: Add a subject and field to create
an adequate useful action
There are cases where the original subject and field do exist, but they
are not sufficient to create an adequate useful function:

F
Subject Object

Then we can add another subject and field to reinforce the effort,
that is:

F
Subject Object
F2
Subject 2

Example 9.14 Using only mechanical means to remove wallpaper is not
efficient, but after spraying steam onto wallpaper, it will be much easier to
remove.

Method 3: Improve the object
In the case of inadequate useful action:
