Development and Research on Incontinence Underwear for the Elderly

Abstract This study investigates the living conditions of elderly individuals with urinary incontinence and their usage of related products to assess their actual needs, including comfort, convenience, and affordability. Based on these findings, innovative design work was conducted, involving structural design, fabric preparation, and process selection. Ultimately, through product performance evaluation and refinement, the design requirements for comfort, convenience, and affordability were achieved. This research holds significant importance in addressing urinary incontinence issues among the elderly and can be applicable to individuals with restricted access to toilets or those engaged in prolonged activities. Furthermore, the study provides a valuable reference for designing and developing functional garments that cater to practical needs. With further production and market promotion, this research outcome is expected to yield greater value and impact on a larger scale.

Artificial Intelligence and Video Game Creation: A Framework for the New Logic of Autonomous Design

Autonomous, intelligent tools are reshaping all sorts of work practices, including innovative design work. These tools generate outcomes with little or no user intervention and produce designs of unprecedented complexity and originality, ushering profound changes to how organizations will design and innovate in future. In this paper, we formulate conceptual foundations to analyze the impact of autonomous design tools on design work. We proceed in two steps. First, we conceptualize autonomous design tools as ‘rational’ agents which will participate in the design process. We show that such agency can be realized through two separate approaches of information processing: symbolic and connectionist. Second, we adopt control theory to unpack the relationships between the autonomous design tools, human actors involved in the design, and the environment in which the tools operate. The proposed conceptual framework lays a foundation for studying the new kind of material agency of autonomous design tools in organizational contexts. We illustrate the analytical value of the proposed framework by drawing on two examples from the development of Ubisoft’s Ghost Recon Wildlands video game, which relied on such tools. We conclude this essay by constructing a tentative research agenda for the research into autonomous design tools and design work.

Design and Implementation of Flexible and Reconfigurable SDF-Based FFT Chip Architecture With Changeable-Radix Processing Elements

In this paper, we propose a flexible and reconfigurable changeable-radix fast Fourier transform (FFT) hardware architecture. It aims to support 48 different FFT sizes and up to 4096 FFT points, which are defined in current 3GPP-LTE communication system. The built-up design structure is primarily constructed on a radix-52 basis of single-path delay feedback FFT and up to 18 various changeable radixes of FFT processing. A design technique of switchable FIFO usage approach is developed to efficiently manage FIFO arrangement for 48 FFT modes. In addition, a design technique of coarse and fine rotating is designed to effectively reduce twiddle-factor circuit area. By using TSMC 40-nm CMOS technology, an FFT ASIC implementation only has a core area occupation of 0.414 mm2 and consumes 49.8 mW in average at maximal working frequency of 526.32 MHz. This innovative design work is competitive as compared to current state-of-the-art works, especially in terms of circuit area cost and power/energy performance evaluation.

Reusing design knowledge based on design cases and knowledge map

Design knowledge was reused for innovative design work to support designers with product design knowledge and help designers who lack rich experiences to improve their design capacity and efficiency. First, based on the ontological model of product design knowledge constructed by taxonomy, implicit and explicit knowledge was extracted from some design cases. The design knowledge was expressed using a constructional organization. With the knowledge map, design knowledge was illustrated to help novice designers reconstruct specific design cases, thus, encouraging innovative design. Four groups of designers were invited to participate in an experiment for the design knowledge map system. The experiment results verified the effectiveness of the method.

Design Fixation in the Wild: Design Environments and Their Influence on Fixation

ABSTRACTMany studies of design fixation ask designers to work in controlled laboratory or classroom environments, but innovative design work frequently occurs in dynamic, social environments. The two studies reviewed in this paper investigated how three independent variables likely to be present in many design environments affect design fixation. The first study found that working with physical prototypes significantly reduced fixation effects, and that working in groups can reduce fixation effects under certain conditions. The second study found that brief interruptions in designers' thought processes during the initial states of the design process also reduce fixation effects. I conclude by discussing what the data from both studies may indicate about the theoretical causes of fixation effects, and what designers might do to prevent fixation from affecting their creative output.
