Product discovery:
To design a product, you must first know what you need. Demand is usually generated through the following channels: 1, technology-driven. The so-called technology-driven type means that with the development of science and technology, many new technologies will be produced. Applying these new technologies to existing products will produce new and better products, which is to develop new products. For example, with the development of automobile, the first animal-drawn vehicle is the prototype of modern automobile, and the power is livestock. Later, steam was used as the power of animal-drawn vehicles, so there was a steam engine. 2. Market-driven. Market-driven refers to what the market needs, that is, people's needs. To give a simple example, for example, there are few dishes in the vegetable market today, and there are still many people who need this dish. Then the price of this dish must be very high today, which is market-driven. If you want to find the demand through the market, you must have keen observation, be able to detect which products are hot in the market at this stage, or predict which products will be called hot products. However, this is not just about finding hot products. It is also necessary to conduct a full market survey to find out which companies are producing this type of products, whether their technology is mature, whether they have mastered the core technology, whether their production can meet people's needs, whether people's demand for this product is increasing, and so on. Market pull is the most commonly used method to generate demand. 3 product update. Product update is suitable for a product that has been produced and the technology is very mature at present, but through the questionnaire survey, we will find that there are still many places in this product that can not meet people's needs, so we can seize this to update the new product. For example, God Drag, Apple, etc. 4, commissioned by the user or issued by the competent department.
Project planning:
Project planning refers to the planning of product design process after finding the demand, including team building, task allocation, time arrangement, cost calculation and so on. 1. Build a team. Choose technicians according to the functions of the products to be produced and the skills needed to realize these functions. Choose more people for the core technology. In short, the distribution of personnel should be reasonable. 2. Task allocation. The function of a product can be regarded as a system. To realize the function of this system, we must first realize the function of subsystem, and there are many subsystems below it. Therefore, we should start with the smallest subsystem and assign the function of the smallest subsystem to everyone to form a system function together. 3. Time schedule. That is, to complete the specified tasks within the specified time, which can be achieved through Gantt chart. 4. Cost calculation. While meeting functional requirements, the cost should be minimized.
Product definition:
Product definition is a parameter for designing products, which should be determined according to the requirements of users or the functions that need to be met. For example, the parameters of a water clock are its timing length, that is, how long it can record at the longest time, and the design parameters of the transmitter are the requirements of its launching distance. In most cases, product definitions are set according to the functions required by users. So first of all, we should evaluate the functions required by users to see if these functions can be realized, and if so, what parameters need to be achieved. Then calculate the cost. Evaluate under what parameters the cost is the lowest, which has little influence on the function, so as to achieve the optimal design requirements. The parameter setting of a product is very important because it has important characteristics different from other products. Different parameters perform different functions.
Conceptual design (conceptual design)
This step is the most important step in the whole design process. After this step is completed, several prototypes of products will be produced, and the optimal design scheme will be finally determined. First of all, it is necessary to analyze what functions the product should realize, how to realize each function, and how to realize these functions. For example, the function of launching things can be realized by converting elastic potential energy into kinetic energy or by converting gravitational potential energy into kinetic energy. Each function is analyzed in this way, and the possible implementation methods of each function are listed. Finally, considering the factors such as cost, performance and implementation difficulty, the best design scheme is selected.
Product development (product detailed design):
Product detail design refers to the design of some details under the premise of determining the product design scheme, such as what material is the best, the cost is relatively low, the friction is overcome, and the accuracy is improved. The detailed design of the product also includes the manufacturing process of the product, that is, according to the functional requirements of each part, the processing process flow chart of each part is compiled, including the requirements of special treatment and assembly. Draw the part drawing and assembly drawing of each part, and then remove the part drawing from the assembly drawing to ensure that every produced part can be assembled. Finally, through some improvements, the first product prototype was manufactured and related experiments were carried out.
Product support (product support)
After making the first prototype, contact the user or developer to see whether the produced products meet the requirements, rationalize and improve those that do not meet the requirements, and finally write the user's instruction manual. When writing instructions, pay attention to using common language that users can understand, and don't use technical terms. We must apply for a patent. Next, the documents of the whole process from design to manufacturing are sorted and filed, so as to update the products in the future. Finally, the design products are recycled and scrapped.
