Re-Inventing
"The ironic expression is well known.
To invent the bicycle again means to think of nothing new.

But, even when re-inventing a bicycle you can
make several fantastic discoveries...

A bicycle has no limits!"

M. Orloff

Re-inventing is the fundamental method of the teachings of modern TRIZ.

In re-inventing, beginners study problems with known solutions that are represented in the format MAI so that they can understand how this problem would have been solved based on TRIZ and how they can solve similar problems in the future with MAI and TRIZ.

Let’s now look at an example of a simplified re-inventing with the use of the scheme MAI T-R-I-Z.

A very simple example:
Perforated corner of a page in an appointment calendar.

Diagnostics

To prepare an appointment calendar so that it can be opened quickly to the necessary page, we rip of the corners of all previous pages. This leads to ugly tears. To rip carefully and accurately allows a more even corner, but this takes more time. The goal (trend) is: How can we ensure a better form of rip while not losing too much time?

Reformation

Non-formal standard contradiction: To rip off the corner while maintaining the external form of the appointment calendar means loss of time.

Graphical representation of this model:


Formal standard contradiction and recommendations of the A-Matrix in classical TRIZ:


Transformation

The method "02 preliminary action" is used to eliminate the contradiction. Concretely this means that the corners of the pages were previously perforated with a machine according to a pre-determined line (see diagram).


Verification

Plus: The contradiction is eliminated because corners are ripped off along one and the same form and without extra loss of time.

Minus: We have to introduce extra technological operations into production, i.e., the costs of the calendar will rise.

Conclusion: We can construct a new problem in inventing.


Extraction is a special variation of re-inventing.

The task of extraction is to find the appropriate TRIZ method of inventing that objectively is a part of every invention when we hypothetically assume that this invention was made based on TRIZ.

The process of extracting models and methods of TRIZ for any given selected object for investigation includes the following steps:

  • a known or agreed upon prototype needs to be selected that represents the results of an improvement in the object of investigation;
  • the properties and construction of the object to be investigated need to be compared with the prototype and any differences should be noted;
  • now you determine which methods and models of TRIZ could contain improvements in the object for investigation when compared to the prototype if this improvement had been made based on TRIZ.

Extraction is also called simplified or express re-inventing.


Re-inventing and Extraction
are effective methods of modern TRIZ
to rapidly learn the methods and models of TRIZ.
