Definition of System, TRIZ, How to Invent

From the textbook definition of a SYSTEM, one can see how TRIZ thinking for inventive problem solving can emerge.

A System is defined as, " A set of elements interacting together to achieve an objective or perform a function"

Set of elements (can themselves be viewed as systems as well).

System implies that it exists to achieve an objective or perform a function. If there is no function or objective, we can not define a system. Set of elements also define the boundary of the system, everything else is the environment in which system operates.

Interactions between elements lead to emergence of the system function, these interactions can be in space or time coordinates or under specific conditions (one can see the mapping to TRIZ).

In the process of performing a function/achieveing an objective, the system may have to interact with the environment - this will lead to the useful function being achieved, however, since system will be creating some change in the environment in the process of performing its function, it will create a harmful effect as well. one should strive to make/design the system in such a way that useful functions are achieved but all harmful effects are reduced or eliminated (the TRIZ concept of contradictions). This also gives us a peep into the evolution towards IDEAL system - another powerful TRIZ concept.

There are certain emergent properties of the system that are not explicitly mentioned/included in the definition of the system. the interactions between elements may lead to certain properties that the system designer would not have thought about. This is becoming more and more the case with complex adaptive systems (CAS). Since the definition of system explicitly doesnt include CAS, TRIZ also could not define the complex adaptive systems - here methink is the opportunity to integrate TRIZ thinking with the concepts, theories and methodologies of Complex Adaptive Systems.

Let us look at the Ideal System based on the system definition

Ideal System

1. Minimum set of elements => ZERO Elements
2. Minimum interactions => ZERO Interactions
3. No Harmful effects/Only useful Functions => No/Minimum interaction with the environment

Hi Navneet:

Nice portray of Triz concept. While I am reading the concept I started comparing BPM to Triz concept. And, surprisingly, I could not able to differentiate both in conceptualization. Please let me know if you have any comments on my comment.

Maybe it is just the TED Video I viewed recently (http://www.ted.com/talks/murray_gell_mann_on_beauty_and_truth_in_physics.html)

but I vehemently disagree with the quoted below. See Murray Gel Man,Nobel price winning particle physicist who published a theoretical paper which was against 7 experiments and all evidence just on the criterion that the equations were elegant (symmetry or consistency) and was proved correct. The ditto existed for Einstein relativity.

"Of all the truth filters - Science - the experimental and exploratory way of establishing truth has been the cause of technological progress of the world and our understanding of the current and future world"
