There is evolution because requirements and problems exist
It is common knowledge in TRIZ that technology evolves
following certain rules.
Evolution occurs to solve requirements and problems to functions.

Remaining items: variable valve structure, lessfriction and light weight piston and crank ,better efficient oil pump and others

Even if “control adjustment" in technical evolution pattern has improved, it
has basically not changed in the mechanistic point of hardware(a product configured by mechanical system only, which doesn’t evolve
without requirements)3

Product or technology where TRIZ cannot be used?
There are some production and business goods for which the customer
demand has not changed for a quite while.
In case, machinery products has none any revision since start production.
Keeping same performance and function by original structure, cause to nodifference products between competitors, and no differentiate technology
elements
The product has same value (F/C) against competitor and no any attractive
quality

The product keeps same structure because there is not any improvement by
TRIZ
There is not any appeared problem according to customer's requirement＜Because it is not necessary to use TRIZ, do not guess to operate TRIZ＞
However, the product may not be a selected
product without differentiation

The product does not have evolution cause to no
customer requirement or problems claim
In case of multipurpose engine which use for power plant on
working machine in agriculture and forestry
Requirement of power plant engine is atleast turning shaft
Same power plant engine is supplied
several ten years because customer
satisfied as it isDomestic engine manufacturer produced
12,072,000 units of gasoline engine at domestic
and foreign plants

Engine speed has been fixed, any engine
structure is OHV system, any engine createssame horsepower. these situation means there
is no any significant difference

horsepower
load responsibility
fuel consumption ・oil consumption
・consumable goods cost
durability ・reliability
small size ・light weight
quietness ・vibration lessinspection interval
maintainability
easy handlingexhaust gas cleanness5

At the OEM manufacturer's standing point, theengine is one of configuration parts• multipurpose engine manufacture's important business point is , if engine ischosen by working machine manufacturer as much as possible , many ordered
engines make mass production and lower price also become competitive
products• however, according to working machine manufacturer's standing point, engine
unit is only power plant for working machine and no any difference with otherengines. because company chooses lower price engine from same horse power,
Other than horse power such a functions which are common as well

Applied sample of multipurpose engine

cultivator

generator

Water pumplawnmowertransporter

【Question】 How to make discrimination• Working machine manufacturer‘s
requirement on multipurpose engine isjust horse power, price has been decided
by horse power amount• Basic engine structure is almost same
dimensions and horse power, also
displacement, size and weight are notmuch difference
Value ( divide Function by Cost ) comparison is very closeeach other, products does not have any attractive quality
requirements （ commodity products）
How to make engine discrimination by multipurpose
engine manufacture, this situation for certain choiceon Working machine manufacturer
7Supposition at products planning conferenceof engine
Discussion in products planning , the subject is almost
same characters between all competitors
The latest new engine should be satisfied byworking machine manufacturer's requirement
planning staff

Working machine manufacturer's first priority is
the price. Horse power is only for comparisonengineeringstaff

It is difficult to discriminate with pricewise
Therefore, it is needed to prepare newly requirements
Any other competitors use same structure
design , crank mechanism and OHV
movement mechanism also same
Cost down analysis has been done , there
is no any quality requirement
However , we cannot sale engine that issame as competitor
Is there none of exclusive design ?

cylinderhead

castingsurface• Mating surface of cylinder head against cylinder
where is casting surface but no-machining• If this situation for cost down as no-machining , but
die-mold life become shorter , not exactly reduce costfor business• Well , what is the purpose to adopt casting surface9Supposition at products planning conferenceof engine selection
Engineering staff of engine manufacture how he can explain toworking machine manufacturer's staff as satisfied
Any engine manufacture has almost samefunction and cost on engine

Do not compare engines with only externalfunction and cost , look carefully about
technical differences

Most machining manufacture machines
cylinder head mating surface. Withoutmachining the mating surface as casting
surface what is only our company. Itmeans internal engineering and quality
control as higher engineering level. We
assure to buyer what choose our products.
That is good sales talk.

• for the responsible person of engine selection as target
customer can satisfy , and also possible to explain in own
office , new competitive selection axis without function or
cost that is " mating surface by casting surface "• The view point mere cost down which cannot be
discrimination.

Importance is before TRIZ
• The products on leading company will be sold as expectation.
Products on leading company has competition ability and somedifference between others( Idea of casting surface which cannot
contemplate from current quality requirement or value enrichment )• if does not conscious newly competition axis , work hard withsmall amount of cost down , continue current process such as adopt
import parts which procedure does not contribute effective
competition• Newly BNE theme can be used TRIZ such subjects are "machining
less mating surface to be sealed against combustion pressure"and"extend die mold life at mating surface"
Simple structural machines are usually on stagnant technical evolution TRIZ
action for these products , pre-stage of TRIZ practice consider sales talk relate
to product enrichment what is important13

Develop products which to be sold
Latent needs to be grasped target customer
Any manufacturer's products have same structure.
They are no difference with function and cost.
Sales section should work hard for saleplanning
staff

Produce good product which does not relate
to good sales. but, good sold product is good
product. It is important to develop andproduce for good saleengineering
staff

Extract quality requirement which does nothelp for new subjects. Reduce cost subject isalso face to dead lock

Now , how to operate ?
in the past , introduced many conception method. which maybe easier toextract improved idea for products. so , try it to improve subject.
Concept mining
Think about customer's satisfaction what the latency needs without saying

Fault listing method
That remind I maybe improve it , the point of view about looking for
fault then might be found newly ideas

Opposite setting method
think about reasonable situation , dare contradict proper subject that
contradict venturous , it may create new conception by other thancurrent point of view

Focusing method
element or character at the none related new field , forcibly connect tothe subject then reach to new conception
17

Hypothesize concept mining andmountaineering chart
Everyone has desire as I want to be so on. But for now , moveon one step instead of high jump toward summit of desire.
When consumer purchase product who choose for one's desireof self satisfaction but function of product.
