phase planes (based, for example, on Derbenev’s transformation), transition from microwave to optical (recall radar and
CPA, or conventional and laser acceleration), and using time–
energy correlation (laser pulse or bunch compression).
The reader can perhaps already add other inventive principles to this list — in fact, one of the purposes of keeping
the unfilled spaces in the tables above is to fill them in, during the proactive process of learning.
11.2 Trends and principles
Standard TRIZ describes not only the inventive principles,
but also the laws (trends) of the evolution of technical systems. Knowledge of these evolution laws can help to create
innovative inventions.
There are just a few laws/trends of the evolution of technical systems and they can be described in broad terms. The
inventive principles, however, are more concrete, as they are
unique approaches that help to solve contradictions — there
are several dozens of these.
The lists of additional AS-TRIZ inventive principles described in Table 11.2 should not be interpreted as cast in
stone. Compiling such tables should instead be considered
as a process of proactive learning parallel to the application
of the TRIZ method to science. A critical analysis is therefore
appropriate.
With this notion in mind, we would now like to look more
carefully at the inventive principle “from microwave to optical” that we introduced in Table 11.2, and discuss whether
this is indeed a principle or rather a general law (trend) of
the evolution of technical systems.
11.2.1 TRIZ laws of technical system evolution
Standard TRIZ defines three types of laws of technical system
evolution — static, kinematic and dynamic.
The three static laws are as follows. The TRIZ law of the
completeness of the parts of the system states that a system
should have the following four parts: an engine, a transmission, a working unit and a control element. The law of energy
conductivity of the system says that every technical system is a
transformer of energy and the energy should circulate freely
and efficiently through these four main parts of the system.
The law of harmonizing the rhythms of the parts of the system
suggests that the frequencies and periodic motions of these
parts should be in sync with each other.
The three kinematic laws are defined in standard TRIZ as
follows. The law of increasing the degree of ideality of the system
states that the “ideality,” which is a qualitative ratio between
phase planes (based, for example, on Derbenev’s transformation), transition from microwave to optical (recall radar and
CPA, or conventional and laser acceleration), and using time–
energy correlation (laser pulse or bunch compression).
