Research on Application of Humanized Design in Product Design

This paper takes soybean milk machine as an example. Nowadays, soybean milk machines on the market all adapt rotational flow to cut the beans and electric heating tube to heat. Whether they have filter nets or not or the beans are dry or wet is not the main factor to classify soybean milk machines. Instead, design is the most competitive factor. In other words, the overall design and user experience are important factors to subdivide soybean milk machines. Figure 1 shows the family income structure of people who drink soybean milk.According to the consumer survey in 2014, different family incomes have little effect on preference of people who drink soybean milk. Structure charts of urban market levels show that in 2014 the sales volume of soybean milk machine in markets of mega cities takes 40% of the total, and mega cities are the largest markets of soybean milk machine; markets in megapolis and other markets both take half of the remaining 60% share. (Mega cities refer to cities with a population over two million; megapolis means cities with a population between 100 to 200 million; The large cities and under refer to cities with 1 million people or less). Figure 1 Yield analysis Figure 2 Classification Figure 2 shows owning rate of small electrical appliances in urban families. Based on a consumer survey in 2014, 48% of urban families have soybean milk machine, which is much lower than the owning rate of electric cooker and induction cooker. In summary, it can be seen that soybean milk machine will be a necessity of our life just like TV and computer. As more and more people concern about fitness and health maintenance, there will be an increasing number of Chinese families using soybean milk machines. Less affected by age and family income, people will not pay too much attention to its price comparing to food safety and delicacy. Besides, soybean milk machine has stronger price advantage than others. Market is an important factor affecting the design, and in some time, it is the market that plays a vital role in design. 1. Analysis on the existing soybean milk machines From the aspect of soybean milk machine market, Joyoung, Midea, Donlim, Philips and other brands take more than 80% of total market share. Next, soybean milk machine of these three brands-Joyoung, Philips and Midea analyzed below. 3rd International Conference on Mechanical Engineering and Intelligent Systems (ICMEIS 2015) © 2015. The authors Published by Atlantis Press 500 1.1Analysis on structures As is shown in Figure 3, soybean milk machines on the market basically use this structure.In this separation structure, technical and functional components are gathered in the upper part of the soybean milk machine, and the lower part made of stainless steel is only used as a container. Control room is responsible for the entire computer-controlled process of making soybean milk. Blades are responsible for the high-speed rotation for breaking the soybeans. Level electrodes are responsible for detecting the water level to prevent dry heating. Anti-overflow electrode is responsible for detecting the water level to prevent overflow. Electrical heated tube is responsible for heating the entire soybean milk. Figure 3 Analysis on structures 1.2 Analysis on appearance After analysis on structure, appearance of soybean milk machines will be analyzed in the following part. Because of the separation structure, the upper part of the machine has a handle to control panel while the lower part has a side handle. Although the locations of socket holes are different, they are basically in the upper part. As a whole,the appearance of the machine honestly reflects the function and use, but the overall image of the product need to be improved because it lacks integrity and doesn’t fully consider about the using process. For example, after the making of soybean milk is finished, the whole upper part has a certain temperature, but there is only one handle in the upper part, so it is clear that there is no suitable placing angle. The only solution is to put it in a bowl or on a board to wait for cleaning. All the functional opponents are gathered in the upper part, so the machine has a certain weight and is too heavy to move, so it is both inconvenient and insecure.Instead, the lower part just plays the role as a “reaction chamber”and is not made full use of. Comparisons among soybean milk machines of brands Yoyoung, Philips and Midea indicates that although they have various styles and qualities, the basic pattern is the same, and has never been greatly improved. So there is a wide space as well as a big challenge for further efforts. 1.3 Analysis on materials In aspects of the material of soybean milk machine, the material selection of the inner side is very strict because it has to withstand high temperature. The common materials of the inner side are mainly stainless steel and ABS with high-temperature resistance. As to the outside of soybean milk machine, there is a vast space for development. The appearance of the soybean milk machine is more beautiful and of finer quality. The outside materials are stainless steel, ABS and so on. Surface treatment techniques include brushed metal, electroplating, LED decoration and so forth. There is a wide-open space on exterior design. 1.4Analysis of Operating Mode The existing soybean milk machines almost adapt keys operation. Under the guidance of a given computer program, press the key to start and it needs no more time to manage. The operation mode is a direct response to functions, which need to be improved with people’s higher standard for flavor. The design of operation interface is an important aspect. The operation interface is used to communicate and exchange information, so the quality of the operation interface directly determines the humanization of the product. The design could also refer to other technologies that other products
