Abstract According to the increase in building size and lack of skilled laborers, layout operation has high demands on automation for productivity and quality improvement. With such a background, research has been recently undertaken to develop an automated layout system based on marking robots for structural work in Korea. Although there are several robot-based automation systems under development targeted at interior works, the system for structural work has different functional needs and technical requirements in designing the robots compared with the existing ones. Therefore, this study proposes a conceptual robot design for an automated layout of building structures, based on a systematic design process, by integrating quality function deployment (QFD) and the theory of creative problem solving (TRIZ). With the support of the approach, 11 user requirements and 16 relevant technical characteristics were derived and prioritized, and 15 creative ideas were derived to solve the technical contradictions. The selected design solution improves driving speed by separating driving and marking operations, and the two-wheeled steering drive system with a suspension device allows easier driving control in a narrow and uneven driving environment. The noncontact type of printer head also minimizes the complexity of the device and provides excellent performance in securing marking precision and quality in response to floor conditions. The results of this study will be used for the detailed design of the layout robot system, and the design process can be utilized for designing and evaluating other construction robots and automation systems.

Product Design Process

In the current, highly competitive marketplace, customer demand is a major factor in the product design process. Most firms make an effort to indicate that their products differ from the competitors' products. The purpose of this paper is to understand customers' expectations of and technical requirements for e-stores and to evaluate most popular e-stores in Turkey (i.e., ES1, ES2, ES3). In this study, the authors aim to understand the customer expectations and technical requirements by using quality function deployment (QFD). To prepare the house of quality (HoQ), the authors surveyed 20 experts who are customers who have elite membership (their expenses for these e-stores are more than regular customers and have elite cards) of the three e-stores and academicians. After creating the HoQ, the authors employ fuzzy linear regression to evaluate the relationships between customer expectations and technical requirements and among technical requirements themselves. Finally, the authors use zero-one goal programming (ZOGP) to select the most desirable e-store.

AbstractThis paper addresses the design of a novel bionic robotic device for upper limb rehabilitation tasks at home. The main goal of the design process has been to obtain a rehabilitation device, which can be easily portable and can be managed remotely by a professional therapist. This allows to treat people also in regions that are not easily reachable with a significant cost reduction. Other potential benefits can be envisaged, for instance, in the possibility to keep social distancing while allowing rehabilitation treatments even during a pandemic spread. Specific attention has been devoted to design the main mechatronic components by developing specific kinematics and dynamics models. The design process includes the implementation of a specific control hardware and software. Preliminary experimental tests are reported to show the effectiveness and feasibility of the proposed design solution.

Programming Step

The work of landscape architects can contribute to the United Nation’s Sustainable Development Goals and the associated ‘Leave no one behind’ agenda by creating accessible and health-promoting green spaces (especially goals 3, 10 and 11). To ensure that the design of green space delivers accessibility and intended health outcomes, an evidence-based design process is recommended. This is a challenge, since many landscape architects are not trained in evidence-based design, and leading scholars have called for methods that can help landscape architects work in an evidence-based manner. This paper examines the implementation of a process model for evidence-based health design in landscape architecture. The model comprises four steps: ‘evidence collection’, ‘programming’, ‘designing’, and ‘evaluation’. The paper aims to demonstrate how the programming step can be implemented in the design of a health-promoting nature trail that is to offer people with mobility disabilities improved mental, physical and social health. We demonstrate how the programming step systematizes evidence into design criteria (evidence-based goals) and design solutions (how the design criteria are to be solved in the design). The results of the study are presented as a design ‘Program’, which we hope can serve as an example for landscape architects of how evidence can be translated into design.

Smart clothing plays a big role to foster innovation and to. boost health and well-being, improving the quality of the life of people, especially when addressed to niche users with particular needs related to their health. Designing smart apparel, in order to monitor physical and physiological functions in older users, is a crucial asset that user centered design is exploring, balancing needs expressed by the users with technological requirements related to the design process. In this paper, the authors describe a user centered methodology for the design of smart garments based on the evaluation of users’ acceptance of smart clothing. This comparison method can be considered as similar to a simplified version of the quality function deployment tool, and is used to evaluate the general response of each garment typology to different categories of requirements, determining the propensity of the older user to the utilization of the developed product. The suggested methodology aims at introducing in the design process a tool to evaluate and compare developed solutions, reducing complexity in design processes by providing a tool for the comparison of significant solutions, correlating quantitative and qualitative factors.

The Underactuated Lightweight Tensegrity Robotic Assistive Spine (ULTRA Spine) project is an ongoing effort to create a compliant, cable-driven, 3-degree-of-freedom, underactuated tensegrity core for quadruped robots. This work presents simulations and preliminary mechanism designs of that robot. Design goals and the iterative design process for an ULTRA Spine prototype are discussed. Inverse kinematics simulations are used to develop engineering characteristics for the robot, and forward kinematics simulations are used to verify these parameters. Then, multiple novel mechanism designs are presented that address challenges for this structure, in the context of design for prototyping and assembly. These include the spine robot’s multiple-gear-ratio actuators, spine link structure, spine link assembly locks, and the multiple-spring cable compliance system.

Various architectures exposing certain phases of the design process have been developed. A closer analysis of the presented timelines is leading more to postpone the design solution rather than advancing it in the early phases. This paper advances a new architecture for the design process with the main emphasize on the product functional design, based on functional-constructive knowledge stored in databases, and on the principle of selecting design solutions in an incipient phase and developing them during the further design process stages.

Purpose Small-medium enterprise (SME) service industry is an industry that continues to experience growth in developed and developing countries, including Indonesia. SME service industry that engaged in the service industry, namely, rental for generator set, air conditioner and sound system. In recent years, this SME has been experienced in declining in sales and getting some complaints from their customers. Many studies suggest that service quality and customer satisfaction are the key factors in the service industry. The purpose of this paper is to analyze the quality of service based on the customer’s perspective. Design/methodology/approach Data was collected using a combination of literature review, interview, brainstorming and questionnaires and analyzed by using importance-performance analysis (IPA) and quality function deployment (QFD) model. Findings This research resulted in nine technical requirements that allow the company to focus on these attributes to help the company enhance its customer satisfaction. Practical implications Based on the theory, applying service quality, IPA and also QFD will result in customer satisfaction. Practically the enhancement in customer satisfaction is not as easy as expected. Nowadays, customers always expect more and more and it is impossible to fully captured customers’ needs and always satisfy customers. Nevertheless, for this research company can understand their customers better, companies can evaluate their performances based on the customers’ perspective and know their customers’ needs. The company also know their strengths and weaknesses to allocate the resources and maximize their potential. Last but not least, the company is able to know their strategic priority that needs to be done for their better performance in the future to fulfill their customers’ needs and hope to enhance their customer satisfaction Originality/value A lot of research about customer satisfaction but still limited especially in the service industry in Indonesia using a combination of IPA and QFD model. So this research will give benefit for SMEs in Indonesia to allocate their resources more effectively by looking at the results of the four quadrants of IPA and house of quality (HOQ) framework can be used for a company as the references for their priority strategic option. Yet, to keep improving, the company recommended reviewing HOQ periodically.

Information is transferred through a process consisting of an information source, a transmitter, a channel, a receiver and its destination. Unfortunately, during different stages of the engineering design process, there is a risk of a design idea or solution being incorrectly interpreted due to the nonlinearity of engineering design. I.e., there are many ways to communicate a single design idea or solution. This paper provides a comprehensive review and categorization of the possible sources of information loss at different stages of the engineering design process. Next, the authors present an approach that seeks to minimize information loss during certain stages of the engineering design process. The paper i) explores design process and dissemination methods in engineering design; ii) reviews prior work pertaining to these stages of the engineering design process and iii) proposes an information entropy metric that designers can utilize in order to quantify information loss at different stages of the engineering design process. Knowledge gained from this work will aid designers in selecting a suitable dissemination solution needed to effectively achieve a design solution.

Ismar David was a prolific calligrapher, type designer, graphic designer, and illustrator who also engaged in architectural design and taught calligraphy. He studied applied arts in Berlin, emigrating to Jerusalem in 1932 and to New York in 1952. From the 1930s to the 1990s, he created a wealth of unique designs, most importantly the David Hebrew typeface family. It was the first comprehensive Hebrew typeface family, comprising nine styles that include a true Hebrew italic style and a monolinear style, equivalent to a Latin sans serif. David Hebrew provides an example of how a research-based design process can help negotiate the tension between old and new, leading to an innovative, well-informed design solution. David not only excelled in his groundbreaking approach to Hebrew type design for existing glyphs, but he went a step further, expanding the character set. After David completed the design of his typeface family in 1954, it was partially cast for machine composition by the Intertype Corporation. During that period, David relocated to New York to pursue his creative career.
