Machine design theory

The machine design is through designs the new product or improves the old product

to meet the human need the application technical science. It involves the project

technology each domain, mainly studies the product the size, the shape and the detailed

structure basic idea, but also must study the product the personnel which in aspect the and

so on manufacture, sale and use question.

Carries on each kind of machine design work to be usually called designs the

personnel or machine design engineer. The machine design is a creative work. Project

engineer not only must have the creativity in the work, but also must in aspect and so on

mechanical drawing, kinematics, engineerig material, materials mechanics and machine

manufacture technology has the deep elementary knowledge.

If front sues, the machine design goal is the production can meet the human need the

product. The invention, the discovery and technical knowledge itself certainly not

necessarily can bring the advantage to the humanity, only has when they are applied can

produce on the product the benefit. Thus, should realize to carries on before the design in a

specific product, must first determine whether the people do need this kind of product

Must regard as the machine design is the machine design personnel carries on using

creative ability the product design, the system analysis and a formulation product

manufacture technology good opportunity. Grasps the project elementary knowledge to

have to memorize some data and the formula is more important than. The merely service

data and the formula is insufficient to the completely decision which makes in a good

design needs. On the other hand, should be earnest precisely carries on all operations. For

example, even if places wrong a decimal point position, also can cause the correct design

to turn wrongly.

A good design personnel should dare to propose the new idea, moreover is willing to

undertake the certain risk, when the new method is not suitable, use original method.

Therefore, designs the personnel to have to have to have the patience, because spends the

time and the endeavor certainly cannot guarantee brings successfully. A brand-new design,

the request screen abandons obsoletely many, knows very well the method for the people.

Because many person of conservativeness, does this certainly is not an easy matter. A

mechanical designer should unceasingly explore the improvement existing product the

method, should earnestly choose originally, the process confirmation principle of design in

this process, with has not unified it after the confirmation new idea.

Newly designs itself can have the question occurrence which many flaws and has not been

able to expect, only has after these flaws and the question are solved, can manifest new

goods come into the market the product superiority. Therefore, a performance superior

product is born at the same time, also is following a higher risk. Should emphasize, if

designs itself does not request to use the brand-new method, is not unnecessary merely for

the goal which transform to use the new method.

In the design preliminary stage, should allow to design the personnel fully to display

the creativity, not each kind of restraint. Even if has had many impractical ideas, also can

in the design early time, namely in front of the plan blueprint is corrected. Only then, only

then does not send to stops up the innovation the mentality. Usually, must propose several

sets of design proposals, then perform the comparison. Has the possibility very much in the

plan which finally designated, has used certain not in plan some ideas which accepts.

How does the psychologist frequently discuss causes the machine which the people

adapts them to operate. Designs personnel''s basic responsibility is diligently causes the

machine to adapt the people. This certainly is not an easy work, because certainly does not

have to all people to say in fact all is the most superior operating area and the operating

process.

Another important question, project engineer must be able to carry on the exchange

and the consultation with other concerned personnel. In the initial stage, designs the

personnel to have to carry on the exchange and the consultation on the preliminary design

with the administrative personnel, and is approved. This generally is through the oral

discussion, the schematic diagram and the writing material carries on. In order to carry on

the effective exchange, needs to solve the following problem:

(1) designs whether this product truly does need for the people? Whether there is

competitive ability

(2) does this product compare with other companies'' existing similar products?

(3) produces this kind of product is whether economical?

(4) product service is whether convenient?

(5) product whether there is sale? Whether may gain?

Only has the time to be able to produce the correct answer to above question. But, the

product design, the manufacture and the sale only can in carry on to the above question

preliminary affirmation answer foundation in. Project engineer also should through the

detail drawing and the assembly drawing, carries on the consultation together with the

branch of manufacture to the finally design proposal.

Usually, can have some problem in the manufacture process. Possibly can request to

some components size or the common difference makes some changes, causes the

components the production to change easily. But, in the project change must have to pass

through designs the personnel to authorize, guaranteed cannot damage the product the

function. Sometimes, when in front of product assembly or in the packing foreign shipment
