What should emphasize is that if designs itself does not request to use the brandnew method, it is not necessary to use the new method merely for the goal for transformation. In the preliminary stage of design, should allow designer fully to display the creativity, not restraint to each kind of restraint. Even if have many impractical ideas in early time, they can also be corrected before plan blueprint. Only in this way can not stop the innovation. Usually, must propose several sets of design proposals, and then perform the parison. It is possible that some ideas have been used in the final plan which is not accepted before. The psychologist frequently discusses the causes of how could people adapt to machine which operate. A designer’s personnel39。s basic responsibility is diligently causes the machine to adapt the people. This certainly is not an easy work, because the most superior operating area and the operating process to all do not exist in fact. Another important question, project engineer must be able to carry on the exchange the consultation with other concerned personnel. In the initial stage, designer has to exchange with administrator on the preliminary design, and be approved. This is generally through the oral discussion, with schematic diagram and the writing material. In order to carry on the effective exchange, needs to solve the following problem: (1) Whether product designed is truly needed for the people? (2) Whether this product has petitive ability pare with other pany’s existing similar products? (3) Whether this kind of product is economical? (4) Whether this product’s service convenient? (5) Whether this product sale well? Whether can gain? Only time be able to produce the correct answer to above question. But, the product design, the manufacture and the sale only can continue on foundation of the above question preliminary answered. Project engineer also should consult together with the branch of manufacture for the finally design proposal through the detail drawing and the assembly drawing. Usually, can have some problem in the manufacture process. Possibly can request to some ponents size or the mon difference makes some changes, causes the ponents 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 experiment only then discovers in the design some kind of flaw. These instances exactly showed the design is a dynamic process. Always has a better method to plete the design work, designs the personnel to be supposed unceasingly diligently, and seeks this better method.10
