Essentially, design is a problem-solving process. It starts from the problem and carries out various activities around it. Therefore, the design must start with the investigation of demand and analysis of information, find and clarify the problems that need to be solved and are worth solving, and on this basis, put forward the design scheme and clarify the design requirements. To understand why design, what is the purpose of design, and who is the target of service.

2. Make a design plan

On the basis of finding problems and defining requirements, the next thing to do is to collect the information needed for design as widely as possible through various channels. Through the induction and analysis of all kinds of information, the main factors affecting the design are excavated, and various design ideas are boldly put forward, and the final design scheme is determined by screening all kinds of ideas according to certain conditions. This is the process of making a design plan.

In this process, we should boldly break through the shackles of traditional concepts and always make it clear that different materials and structures can produce different design schemes; Any design scheme has the possibility of improvement, and there will never be only one good scheme. ?

Collect information:

Relevant information can be collected through user surveys, expert consultation, consulting books and materials, listening to radio and television, browsing the Internet and other channels. Understand the characteristics of the product to be designed: material, structure, technology, function, size, consumer groups, market positioning, etc. Then, summarize the survey results. Design analysis:

In the face of all kinds of information collected, according to the design requirements, find out the main problems that need to be solved in the design and analyze their possible solutions.

Scheme conception:

Scheme conception is the most challenging link in the design process, which requires us to boldly conceive according to the design requirements, strive to tap our creative potential and put forward several ideas to solve the problem.

Scheme demonstration:

The design ideas produced in the process of conception are often vague. In order to make them concrete, we usually use sketches to transform them into visual images. At the same time, these ideas are scattered, from which we can't see a complete design scheme, so we should synthesize these ideas.

Make a model or prototype

After the scheme selection is completed, it is necessary to start making models or prototypes. Generally speaking, model making includes two stages, namely, drawing patterns and making models or prototypes. For patterns, we can draw them by hand or by computer.

4. Testing, evaluation and optimization

To make clear whether the design scheme is feasible, we must also carry out various tests and evaluations, optimize the design scheme and improve the product prototype.

Testing: after the model or prototype is made, it is usually tested. The purpose of the test is to check whether the product can meet the predetermined design requirements in terms of structure and technical performance during operation and use.

Evaluation: On the basis of testing, it is necessary to comprehensively evaluate the design scheme and products. This evaluation needs to be repeated in the design process.

Optimization:

In order to optimize the design scheme, we should not only analyze the specific records of testing and evaluation, but also pay attention to public opinion surveys to clarify the direction of improvement. Generally speaking, we can investigate three typical groups, namely experts (sellers, manufacturers), potential customers (potential users) and users (users), and collect specific optimization opinions.

5. Use and maintenance of products

In the process of product use, correct use and maintenance can not only make the product better meet people's needs, but also prolong its service life. Therefore, it is particularly important for product users to master the correct use and maintenance methods. To this end, we usually have to design a product instruction manual.
