Analysis of industrial product modeling design

the modeling design of mechanical products belongs to the category of "industrial design". Industrial design is a new frontier discipline in modern times. It is a creative design that applies engineering technology and artistic means to design and shape the image of products, and finally unifies it in the function, structure, process, agreeableness, visual communication, market relations, etc. of products, so as to achieve the harmony of human machine (product) - environment. With the advance of the times, the development of science and technology, the improvement and change of people's aesthetic concepts, the modeling design of mechanical products, like other industrial products, is constantly developing and changing to a high level. There are many factors that affect the shape design of products. However, the shape design of modern products mainly emphasizes meeting the needs of people and society, making beautiful, exquisite and pleasant products for people's life and production activities, and improving the level of material civilization and spiritual civilization of the whole society. This is the main basis and starting point of modern industrial product modeling design

1 timeliness of mechanical product modeling

people are in different times and have different spiritual aspirations. When the modeling image of mechanical products has the spiritual significance of the times and conforms to the characteristics of the times, these "shapes", "colors" and "qualities" with special appeal will show the characteristics of the times that products reflect the scientific level of the times and contemporary aesthetic concepts, which is the modernity of products

in the 1940s, around the end of World War II, due to the turbulence and suffering brought by the war, people had a heavy heart and hoped for a peaceful and safe environment. Therefore, mechanical products at that time mostly adopted soft arc shape, and "streamlined" products became fashionable, which formed the characteristics of industrial modeling in that era

in the 1950s, due to human physiology and World War II and other reasons, people were tired of being bloated and full of tension streamline, and visually and psychologically longed for some calmness and relaxation; Belt testing and classification industrial product modeling conforms to the ideas of most people (of course, the development of science and technology has gradually broken the monopoly of "streamline"), and gradually straightens the curve, so there is an era modeling with the characteristics of straight lines and increased curvature

From 1960s to 1970s, due to the further development of science and technology, especially the emergence of a large number of new materials and processes, the product modeling has the possibility of refinement, simplicity, affirmation and straightness of change in the manufacturing process; Therefore, the square and straight rectangle and the trapezoidal shape that breaks the unity of square and straight with oblique and dynamic breaking and static breaking appear, which enlivens the atmosphere of visual art

After the 1980s, due to the rapid development of large-scale integrated circuits, numerical control, microcomputers, electromechanical integration and other technical forms, new materials and processes such as plastic electroplating and engineering injection molding have emerged one after another, and the industry has shown a larger and higher development trend. In this pluralistic situation, people's aesthetic requirements and standards from reason to concept are or will undergo a qualitative change. As a product modeling, it truly reflects people's bold and persistent pursuit of high technology. The selection of geometric modeling makes the layout and composition more concise and lively, rational and abstract, and the diversified expression full of geometric beauty and mathematical beauty, which naturally becomes the fashion of modern product modeling

from the color analysis of products, in the 1950s after World War II, people longed for stability and peace, so at that time, people liked dark and quiet blue and green cold tones as the color of industrial product modeling. After the 1960s and 1970s, people's life was relatively stable, so the hue gradually changed from dark to bright, from cold to warm, and from monotonous to colorful. In recent years, with the development of aerospace industry, people have tried their best to reflect their strong pursuit and love for interstellar communication through product modeling colors. They like iron gray with metallic luster. Although modified plastics can be used to achieve "cosmic colors" such as silver gray and silver black by measuring various methods

2 product color design and proportion design

in product modeling design, two principles of color and proportion design must be emphatically considered

2.1 color design

in the image of the whole product, color first acts on people's visual perception, which can be said to be "preemptive". If the product color is handled well, it can coordinate or make up for some deficiencies in the shape, making it more perfect, and it is easy to win the favor of consumers, and get twice the result with half the effort. On the contrary, if the color of the product is not handled properly, it will not only affect the function of the product and destroy the overall beauty of the product shape, but also how to choose to become a difficulty for people, which is easy to destroy people's working mood, and make people feel boring, dull, indifferent, and even depressed, which distracts the operator's attention and reduces work efficiency. Therefore, in the modeling of products, color design is an important work that can not be ignored, and the choice of its hue is crucial

tone is the overall color feeling of industrial products at a glance. It can show liveliness and liveliness, fineness and solemnity, indifference, dullness, kindness, lightness and so on. The choice of hue should be particularly careful. Generally, it can be determined artistically according to the use, function, structure, timeliness of the product and the likes and dislikes of users. The standard for determination is that the color and shape are consistent, the shape is assisted by color, and the shape and color are bright. For example, the purpose and function of the aircraft is to carry passengers and objects at high altitude and high speed, so its main color is generally handled as bright and colorful silver white, which easily makes people feel the lightness and fineness of the aircraft, that is, the shape and color are consistent, and color helps shape; If, on the contrary, the aircraft is painted black and gray, it is easy to make people doubt whether it is bulky enough to fly. This is that the color destroys the shape and the hue is chosen incorrectly. Generally, the determination of hue should also refer to the following points:

(1) using warm hue has a warm effect, and using cold hue will make people feel lonely

(2) taking the warm color with high chromaticity as the main tone can make people feel exciting, and taking the cold color with low chromaticity as the main tone can make people calm and think

(3) high brightness tone is light and bright, and low brightness tone is deep and solemn

in a word, tone is a color design element that plays a dominant and unified role in the overall color feeling

2.2 scale design

correct scale and scale are the basis and framework of perfect modeling. Generally speaking, as long as the proportion does not violate the product function and material and technical conditions, it can take a variety of change combinations to show the quantitative change relationship between the whole and part or part and part of the shape, such as size, thickness and length. The scale is relatively fixed, which refers to the degree and scope of adaptation between the size of the shape and the size of the human body or a certain standard. If the shape has only a good proportion and is not constrained by the correct fixed scale, the design will surely fail. Therefore, the correct order of modeling design should first determine the scale, and then determine and adjust the proportion of modeling objects according to the scale. For example, the guardrail of the bridge, the shield of the machine tool, the trunk of the car, the seat of the bicycle, and the pen holder of the fountain pen should first consider the size of the shape, that is, the length, width, height, diameter, etc. that the human body size adapts to, and then the proportion and details of the shape should be adjusted

the scale of the shape should be reasonably arranged and coordinated according to various factors affecting the combination. These factors basically include three aspects: function, material and technical conditions, aesthetic fashion and so on. The modeling object with coordinated proportion is not only beautiful, but also reasonable to use, which can give people a comfortable and cordial feeling. Several proportions commonly used in the modeling of mechanical products are:

(1) the golden section

the golden section has been recognized as the most beautiful scale since ancient times. The composition of many beautiful scenery in nature is reflected by the golden section proportion. The optimization method popularized by Chinese mathematician Hua Luogeng is also 0.618. The golden section proportion adopts the preferred number of 0.618 as the base, so that the ratio of the two segments constituting the proportion is 0.618. This ratio is in line with human visual characteristics and the internal scale of the human body. Its proportion is beautiful and harmonious, rich in changes, and has a certain sense of regularity and stability

(2) root mean square ratio

if the short side is made to be 1 in a rectangle, and these irrational sequences are applied to the long side design, there will be a very strict, natural and regular repetition reflected in the geometry, that is, this is the root mean square ratio. This proportional relationship has a harmonious and coordinated dynamic equilibrium aesthetic feeling, so it is widely used

(3) modulus theory

modulus theory is a school of thought in artistic modeling. They believe that the shape of beauty is derived from one or several modules from the whole to the part, and from the part to the detail. The size series containing common scale factors is an internal law. Starting from the absolute scale of the human body, it selects four basic points: the height of the human hand, the height of the head, the height of the navel and the height of the vertical hand (6. The cement pressure testing machine is randomly equipped with color HP printers, which are 2260 mm, 1830 mm, 1130 mm and 860 mm respectively). After inserting the corresponding other values, The following two sets of Fibonacci series values are formed: (unit: mm)

the first set is... 1830, 1130, 700, 430, 270, 170... Called the red ruler

the second set is... 2260, 1400, 860, 530, 330, 200... Called the blue ruler

these values not only contain the restriction relationship of the middle value ratio, but also basically conform to various scales of human activity range, and can achieve the harmony of human-machine relationship. Therefore, modulus theory is a practical design mode of shape proportion

3 prospect of mechanical product modeling and "concurrent engineering"

for a long time in the future, more simple and purified, more concise, more lively, more rigorous structure, more exquisite technology, and the pursuit of rational beauty are the main signs of mechanical product modeling. The shape of straight line or large curvature circular arc surface plus small circular corner will be used more. The colors will be mainly light and bright bright low color cold and warm tones. For a machine, its main color matching will be "two sets of colors" or "three sets of colors", breaking the gray or "Kaleidoscope" style of color

with the rapid development of science and technology and the continuous improvement of human cultural level, the life cycle of modern industrial products is becoming shorter and shorter. Generally, the modeling life cycle of machine tool products is 5-10 years, while that of electronic and daily-use machinery products is less than 2-3 years, and the speed of innovation is getting faster and faster. Especially for household appliances, almost no major changes are made to the internal movement, so they are re launched with new modeling. In such a high-speed product upgrading competition, as the inseparable main link of modern product design - shape design, structure design and mold design, according to the traditional working practice, the designers of these three majors and departments usually work together to complete the task of industrial product design. However, the speed of such design is too slow to adapt to the new situation of today's rapid development

foreign countries are widely promoting the design integration mode according to a new "concurrent engineering" viewpoint. "The view of concurrent engineering holds that the modeling, structure and mold design of industrial products are related
