• CONCLUSIONI

• A specific methodology developed on the basis of patent information is the TRIZ

methodology (Russian acronym for Theory of the Solution of Inventive Problems).

• TRIZ began with the hypothesis that there are universal principles of invention that

are the basis for creative innovations that advance technology, and that if these

principles could be identified and codified, they could be taught to people to create

or enhance their inventive capabilities.

A Tool for Creative Thinking

• The TRIZ research has proceeded in several stages and more than 2 million patent

documents have been examined, classified by level of inventiveness, and analyzed

to look for principles of innovation.

• Patent information, therefore, provides an extremely useful source of information

for learning and developing creative problem solving and innovation strategies.

A Tool for Creative Thinking

• Level 5: Discovery

• Level 4: First market

• Level 3: Diffusion, new markets

• Level 2: Qualitative Improvement within a technical system

• Level 1: Quantitative Improvement within a technical system

• To create a classification this would be applicable for problem solving,

technology forecasting, and to help with identification of new solution

strategies at the earliest project stages.

it errs by extending short-terms, Ignoring

long-term trends and forgetting common sense

(Ralph C. Lenz)

• One class of constraints is those intrinsic, natural (or physical) limits such as the speed of light, absolute zero temperature, absolute vacuum. In addition there are human limits imposed by the size, shape, and constitution of the human body, the nature of the environment and the earth.

– Macrovariables whose rates of change are conditioned by or subject to any of the above limits will be called intensive macrovariable [intensive]

• Another category of real constraints is absolute but time dependent natural limitsimposed by existing capabilities in tangential areas, viz. other macrovariables.

– A macrovariable subject to a sliding constraint of this type will be classed asextensive macrovariable [extensive]

Technology forecasting

• Forward progress can be achieved if any one of several limitations

(sufficient conditions) are met.

• It will be observed that, as a rule, a technological prerequisite for some

advanced system would be described as removal of a time-dependent

constraint.

Exploration of the adjacent “terra incognita”

• Given a definite starting point, namely a radical pioneering invention, there are

several factors which combine to ensure that subsequent exploration usually

tends to proceed from the known part of the morphological map only into the

nearby territory.

• In other words, it is normal and natural to vary the parameters of the initial

configuration one at a time, keeping the others constant.

…to vary the parameters of the initial configuration one at a time, keeping the others constant.

The only way to describe an invention

is to invent it first

EP2058491 (A2) - Control system for internal combustion engine

Formulate the mini-problem

Define the conflicting elements

Conflicting pair:

Product - Air

Tool – Throttle valve

Problem model

1. Conflicting pair: air and throttle valve.

2. Intensified conflict: a “super high-speed” rotation angle performes a

good response but a introduces a big sovraelongation.

3. Problem: it is necessary to find an X-element which keeps the ability of

the super high speed rotation angle to performe a good response and

prevents sovraelongation.

OZ – Operational zone

• From the intake pipe 22 to the throttle valve 24 (area of negative action)

• From the throttle valve 24 to the engine 12 (area of positive action)

Definition of the Operational Zone:

Area between the intake pipe 22 and the periphery of the throttle

valve 24 - throttle section

• Time before the angular rotation

of the throttle valve is performed

(time before the conflict - T2)

• Time from when the throttle valve

starts to rotate until the throttle

valve reaches the right angular

position (time when conflict occurs

– T1 = sovraelongation time)

OT – Operational time

Formulate ideal final result (ifr)

• The x-element, whitout complicating the system and whitout harmful side effects,

eliminates:

– Sovraelongation

• Within sovraelongation time

• Inside throttle section

CONCLUSIONI

• Si è presentata un’applicazione TRIZ.

• TRIZ è considerato “A Tool for Creative Thinking” che permette di:

– classificare i brevetti secondo livelli di invenzione;

– prevedere l’evoluzione tecnologica;

– innovare un prodotto/processo.

• Si è visto come viene modellato un problema di conflitto tra “tool e prodotto”.

• La definizione di un modello, immerso in uno spazio operativo ed agente in un

certo intervallo di tempo, permette di formulare una soluzione ideale.
