The digital twin can be seen as the link between the physical and digital worlds, and has received widespread attention both at home and abroad. The twin model, after diagnosing, predicting and evaluating, can output the simulation results to the controller for state control of the physical entity, thus achieving consistency between the twin and the physical entity. This paper first analyzes the relationship between the basic concepts of the digital twin. It then introduces the necessity of digital twin in aerospace applications, focusing on the existing applications of the digital twin in the aerospace field.

For example, the humanistic thoughts of the Song Dynasty had a substantial impact on generating a need for ceramics. The first is the value of materials, in which value and price complement each other, whereas cost and function are the strategies influencing their development. In the era of symbolic consumption, a brand is composed of symbolic meaning and the value of symbolic consumption. Its value lies in the process of information transmission through coding and decoding, which convey their own identity and enhance the value. The third is the value of experience required by people in an experience-based economy , which refers to the creation of scenes and the shaping of memories. The fourth is the value of spiritual design, which refers to a comfortable, harmonious, and sacred feeling created by culture and creativity .

For instance, traditional Chinese crafts such as ceramics, paper-cutting, and knitting, requires a considerable amount of time and effort to exercise and practice in order to produce high-quality and culturally compatible works with meticulous attention to detail. The time required for such knowledge and experience accumulation varies from years to decades. The research team visited and interviewed the ceramic handyman Wang Xinghu for four hours on 19 November 2018, who had spent ten years running his own ceramic studio after four years of studying ceramics at the Ceramic Institute. He said that the origin and manufacture of many traditional handicrafts were inherited and developed in the countryside or rural areas of China. However, as rural areas have become more urbanized, an increasing number of young people have chosen to abandon the craftsman life characterized by monotony, repetitiveness, and idleness, causing a dilemma where only older people have consummate traditional craft skills. What further complicated the picture was the failure of craft to attract the interest and attention of young people.

What Are the Career Prospects for Fashion Designers?

The industries with high additional value and enhanced economic productivity should be developed through innovation in cultural diversity. Productive activities and innovation should be improved to further activate local cultures and product innovation. Moreover, technological development, research, and invention should be supported for industrial diversification and a higher additional value for commodities . Communication coverage should be widened to maximize the supply of the Internet services .

As exploratory research of design science, this study also has limitations and deficiencies. First, the reference materials and subject background information were limited. Compared with natural and social sciences, the development and research methods of design science are under continuous exploration and definition; in particular, traditional technology is mostly the product of practice and experience accumulation. Therefore, there are some difficulties in the sustainable exploration of craft product designs based on design thinking, such as the lack of data or insufficient concentration. Secondly, China’s vast territory and rich traditional cultural content have imbued many conventional handicraft products with different attributes, which also posed limitations on the research. Because different craft products have different contents and attributes, there are restrictions when selecting objects for research.

Furniture, such as the MR chair , the Barcelona chair , and the Brno chair . During the worldwide Great Depression of the 1930s, when he had few architectural commissions, Mies earned a living from the royalties of those furniture sales. The Bauhaus produced other icons of modern design, notably the sleek glassware and streamlined table lamps of Wilhelm Wagenfeld. All the design in living things is encoded in a sort of recipe book with lots of information. Information describes the complexity of a sequence—it does not depend on the matter of the sequence. It could be a sequence of ink molecules on paper —however the information is not contained in the molecules of ink but in the patterns.

Chen mentioned that handicraft creation is based on the wisdom and experience accumulated by human beings, who produce the daily necessities through their dexterous hands and materials from nature under the guidance of aesthetics of life. The handicrafts have spiritual value, including practical spirit, what are the 4 dora metrics for devops local spirit, inheritance spirit, work spirit, quality spirit, original spirit, and humanistic spirit, and daily handicraft design strategies have been proposed accordingly . According to Ho, future designers will use their hands, bodies, brains, mind, and emotions in the design process .

The goal of the future designer is to be inspired in different ways to create more products, services, and experiences that are conducive to a better life for human beings, thus having a large and important influence on society . Traditional handicrafts are an expression of culture, which are characteristic of aesthetics, practicality, locality, and refinement, and contain diverse values covering technology, art, and collection . At the core of the United Nations’ Agenda are 17 Sustainable Development Goals . The aim of the SDGs is to secure a sustainable, peaceful, prosperous, and equitable life on earth for everyone now and in the future. The UN has emphasized the future planning of culture, education, and innovation many times.

Crime as an environmental stressor

In this phase, the design team made many rough and simple products or prototypes with special value to test the solutions proposed in the previous phase. This phase is the phase of thinking with the hands in a real sense, and an experiential design strategy was adopted, so that everyone would experience product making and material, craft, and media interaction. Prototypes can be shared and tested in the team or among the designers of other sectors. This is just the phase of experimental formation, and it aims to find out potential solutions to the problems defined in the previous three phases. By the end of this phase, the design team will have a deeper understanding of the internal limitations of products and existing problems and gain a more comprehensive perception of user behavior, thoughts, and feelings in their interaction with the finished products. In this ceramic product design, each workshop member tried his/her best to make ceramic products related to the Chinese 24 solar terms and strived to underline sustainability through the theme, content, and sign.

In summary, this study is an exploratory piece of research on the prospective sustainable development of traditional handicraft design according to the method and procedure of design thinking. In the design thinking method, dynamic thinking and design strategies were proposed for designers. In the “Empathize” phase, strategies like thinking with the body and enquiry learning were used to gain a comprehensive and specific understanding of the sustainability of handicraft design and design tasks, with the aim of generating empathy and resonance. In the “Define” phase, strategies like thinking with the mind and values education were adopted to seek the significance of the sustainable development and innovation of handicraft design and provide evidence for the value assessment of existing problems. At this stage, the key to finding the sustainable value and significance of traditional crafts for modern design is to distinguish between traditional handicrafts and modern design products. For example, traditional handicrafts are often handmade art, and the products are unique and unitary, with each piece featured in its own artistic expression and content, whereas modern design products are often mass produced and mechanized.

• Unlike rational thinking, design thinking places more emphasis on “perceptual analysis”.
• But we cannot assume responsibility for, nor be taken as endorsing in any way, any other content or links on any such site.
• Although sustainability is an abstract concept that is hard to express, continual focus was placed on what was designed thanks to the direction of values in the phase of empathy .
• Editors select a small number of articles recently published in the journal that they believe will be particularly interesting to readers, or important in the respective research area.
• The fourth is the value of spiritual design, which refers to a comfortable, harmonious, and sacred feeling created by culture and creativity .

In such value definition, the first step is to make an evaluation of existing problems according to the establishment of empathy and the experiential learning analysis in the preview step. In this stage, scientific technologies and tools like statistics and formulas can be adopted to achieve more effective analysis and research. The defined value can be taken as the measurement criterion and indicator of the prototype in the later stages.

They also decide on the makeup, the shoes, the accessories, and the overall theme of the look. Every celebrity has their own personal stylist who decides their look for every event that they attend. This phase is the last in the five-phase model, but it is also a process of repetitive operation. The results in the test phase are often used to redefine one or more problems, to show the use conditions, to understand the thinking, behaviors, and feelings of users, and to lead to empathy.

Variations in perceptions of danger, fear and preference in a simulated natural environment

According to the relevant research in Section 2, the design of handicraft products requires the designers to possess a certain understanding and mastery of the sustainable value of handicrafts. Although the works should bring the basic functional requirements of users, the difference in the value of works and the transmission of cultural codes should be emphasized. In this study, we believe that it is necessary to include the opinions of multiple experts due to the diverse professions that comprise the field. Therefore, according to Weimer and Vining , the technical indicators for selecting the experts are “analysis” and “politics” . The plan was to select experts from practical industry, academic departments, and design research institutes.

However, attention must be paid to the impact of the bias of experiment participants and the testing procedure on the test . In summary, traditional Chinese handicraft culture has the value and significance of science and humanities, embodied in the cultural identity of its nation. It is necessary to design scientific tools and methods to explore and define its sensibility value. https://globalcloudteam.com/ Only in this way, combined with the design and production of designers, can it be recognized and used by people today. This process represents both the perseverance and a derivation of traditional culture, the juncture where traditional handicrafts beam with revitalization and vitality. In such a context, design science acts as a critical bridge and link between them.

In this phase, the prototype is measured and the appropriate assessment strategy is implemented. According to Norman, testing is the best approach to the exploration of design science. Usually, the expected influence of design can be obtained when a target object is tested and assessed among 5 to 10 people. In this phase, designers think with their souls to feel design and obtain new inspiration. To improve the accuracy and reliability of testing, specific groups or interested persons can be chosen for the test. The experts who are interviewed for opinions and suggestions in the first phase can also be tested, which will lead to more accurate test results.

Dangerous Situations: Social Context and Fear of Victimization

According to our investigations, over 50% of respondents did not know much about traditional craft production. Therefore, the traditional handicraft industry requires attention and protection. In addition to green value, traditional handicrafts also contain social, economic, cultural, educational, local, and environmental values.

The imitation of natural materials and handicrafts in sustainable development is the only way to achieve the circulatory development of the production–consumption system . Sustainable design refers to consciously imitating the visible patterns and relationships in nature and to design works that can provide locals with the necessary food, fiber, and energy . According to the research framework and design procedure, the previous section discussed the sustainable value of the internal design factors of traditional handicrafts in design thinking. Norman believed that design is exploratory and imperfect and involves how to make some influence and obtain some inspiration quickly. This chapter focuses on three stages of design thinking, namely, “Ideate”, “Prototype”, and “Test”. In these three stages, designers design creative and sustainable ceramic products.

Evaluating the Influence of Fear of Crime as an Environmental Mobility Restrictor on Women’s Routine Activities

Specifically, craft is the basis and connotation of design, whereas design is the manifestation and future of craft. Handicraft manufacturing represents a kind of design thinking and process that has existed since human beings first began to make products with their hands. With the improvement of crafts, handicraft products have undergone constant enhancement and application, which in turn has facilitated the lasting development of crafts.

Cultural identity is the understanding and recognition of groups that share the same cultural background and perception of their culture. The continuous accumulation and inheritance of culture have formed a new cultural, ecological circle. Finally, factors affecting the quality of design products include physiological sensory value, psychological emotional value, and spiritual inspiration value. Sustainable design exists to coordinate people, things, and the environment at an incremental value level. Introducing the concept of sustainable value to the design practice of the future designer has prospective significance, but the process of practice, accumulation, and internalization is required to directly reflect sustainable value in the design works. Sustainable development is the essence of the Yin and Yang myth in oriental philosophy and the paradigm of traditional Chinese handicraft value.

The sustainable value assessment indicators of handicraft product design constructed in this study were used to assess the water appliances and fragrance appliances themed on “The Chinese Culture of 24 Solar Terms”. A higher score indicates that the product design complies more with the content of this indicator. Before the assessment process, experts had to read the design background of the product and other related information . Natural science observes the objective world in a quantitative way and explores its logic of necessity through deduction and reasoning.
