Four maternity support garments were designed based on the results of a marketing survey conducted locally. Based on the marketing results and the practical needs of pregnant women, main concepts and criteria of design had been figured out.
Online shopping is getting more and more popular. Among the various products, clothing is probably the one least fit for online sale. A major reason is that customers are not able to decide the clothing fit without actually trying on the clothing of their interests. Virtual try-on systems have thus attracted much research attention in the past two decades. To try on clothing online, the availability of an accurate 3D human body model is a must. 3D human body modeling itself is a challenging research topic in the areas of computer graphics, film animation and clothing technology.
Computer aided design is vitally important for the modern industry, particularly for the creative industry. Fashion industry faced intensive challenges to shorten the product development process. In this paper, a methodology is proposed for sketch design based on interactive genetic algorithms. The sketch design system consists of a sketch design model, a database and a multi-stage sketch design engine. First, a sketch design model is developed based on the knowledge of fashion design to describe fashion product characteristics by using parameters. Second, a database is built based on the proposed sketch design model to define general style elements. Third, a multi-stage sketch design engine is used to construct the design. Moreover, an interactive genetic algorithm (IGA) is used to accelerate the sketch design process. The experimental results have demonstrated that the proposed method is effective in helping laypersons achieve satisfied fashion design sketches.
LED lighting is applied to clothing. It allows a flexible method to provide illumination of lighting. A family of converter topologies is proposed to give this simply method of power conversion. Analysis for the circuits in terms of output power, efficiency and general operation are provided. Two types of LED lighting clothing are developed. One is using super-bright LED embedded on the cloth. This gives active lighting instead of passive lighting. Another one is using optical fibre with grating to form lighting pattern.
The contactless power converter is examined here for power transfer in intelligent clothing which has a number of electronic devices that requires power. Using the contactless power converter that is based on magnetic coupling, the power can be transferred. Magnetic and circuit design, analysis and test will be presented in the paper. A gapped design is used for the magnetic device and a compensation method is implemented in the transformer primary and secondary sides for improvement for power transfer.
Virtual cloth simulation received much attention in the past decade, and the fashion industry has been attracted to use this newly available tool in actual product development process to strengthen the collaboration along the supply chain and shorten the product time to market. This paper serves as an exploratory study to analyse the accuracy of 3D cloth simulation system so as to examine its validity and effectiveness in garment fit evaluation. A four-phase methodology is proposed in this paper: 20 types of woven fabrics are first tested in standard laboratory, and the obtained fabric property data are input to simulate the results of a flare skirt design. Real sample skirts are produced for comparison. An objective evaluation method is proposed to assess the accuracy of 3D simulation by comparing the quality of 3D virtual simulation results. Generally speaking, 3D clothing simulation is accurate because 18 out of the 20 tested fabrics have statistically similar results of 3D simulation and the real sample. The simulated results of the two fabrics are different from the real sample, particularly in the hip areas. Further study is thus required. With the range of validity identified, guidelines can be provided to the fashion industry for the use of 3D simulation system in design and fit evaluation.
