Abstract As digitalization progresses, the development and integration of sensory functions in technical systems become increasingly important. Managing uncertainty, especially in the early phase of ...this process, is crucial to ensure the reliability of the data provided. Therefore, a methodical framework for the identification, analysis and consideration of uncertainty was presented in prior works. In this contribution, the effectivity of the framework is evaluated by applying it to a sensory function for rotational speed and offset measurement of a disk pack coupling using sensor integrating bolts.
Abstract Many of the methods and tools proposed in the literature for validating product concepts are matrix-based, but they do not allow the results to be communicated easily and comprehensibly. ...This is a major obstacle to the integration of such methods. The poor communication of the results of a method therefore represents great potential for better integration of sustainability aspects in product development. In this article, an approach is proposed on how the results of the MECO matrix can be converted into a clear visualization of the reduced environmental assessments.
Abstract Lab-on-a-Chip (LOC) products for point-of-care diagnostics have gained significant attention. However, there is a lack of systematic approaches for LOC product development. To address this, ...we introduce an Attribute Dependency Graph exemplary for a magnetophoretic LOC system for pathogen detection. This model organizes dependencies between the design variables and crucial quantities of interest, such as detectability, cost per test, and test duration. The obtained model helps to manage design complexity and can be adapted to other LOC approaches.
Abstract
In the context of condition monitoring and predictive maintenance, collecting accurate data from technical systems is an important corner stone of the advancing digitalization. For gathering ...precise data of the current state of a system, measurements from within the process can be utilised. To measure in process without disrupting the system is a challenge that can be tackled by using the physical properties of the components of the system. In this paper a method to systematically find such possible sensory utilizable components (SuC), based on their inherent physical effects is presented.
Pests and diseases in agricultural systems cause severe production losses with associated economic impact. Integrated Pest Management (IPM) is a sustainable method to limit these losses. For improved ...implementation of IPM, fully automated monitoring tools are needed to provide instantaneous pest monitoring data and associated real time, user-friendly treatment advice for producers. The application of the Reflexive Interactive Design approach to design an automated pest monitoring tool including an automated pest detection sensor is described with Poultry Red Mite (PRM) as a model target. Three different concepts were designed for the automated mite detection sensor based on a combination of solutions to carry out the key functions. The functioning of the main solutions in the three concepts was tested with live mites to ensure that solutions aligned with the behaviour and biology of PRM in vivo. The best solutions were combined into two different prototypes, which were subsequently tested in the laboratory and on-farm. The most successful prototype of the automated mite detection sensor was situated under the bird's perch, had a through-beam sensor and was able to remove mites from the through-beam sensor area once recorded. Involvement of various multidisciplinary actors, users and varied user networks in the design process was vital for its rapid progress, the quality of the final product and the limited number of set-backs encountered. It is expected that this same design structure, with the addition of an evaluation step, is applicable to the design of automated monitoring tools for other pest species.
•Automated monitoring tools are vital for improved integrated pest management.•Automated monitoring tools are not available for pests in animal husbandry systems.•The RIO approach resulted in the design of an automated mite detection sensor.•Testing of solutions with individual pests should be added to the RIO approach.
Mechatronic design practice was conceived as various successive steps involving expertise. However, employers expect recently graduated engineers to start working with the shortest training period. ...This paper reports a research that developed a simulation tool that introduces modifications and additions to the regular methods of dynamic simulation, integrating in it several of the steps of the systematic mechanic design. The design tool encompasses for each element or object of the simulator seven new features that in an intelligent way gives the student a little design practical expertise. The connection between elements follows the method by wires and the window of assembly includes a workspace where the 3D depiction of all elements is seen and animated according to the values of the variables. The concept was prototyped and now all technological components are available to start the development of a product. This concept, due to the volume of information that it uses, instead of being attractive to cover all fields of knowledge is valuable to adapt to specific fields as academic courses. Potential users evaluated the attractiveness of the concept through a work section, giving good indicators.
In developing countries where sustainable housing design receives insufficient theoretical and practical efforts, decisions about appropriate sustainable design strategies are often made in ignorance ...of situational and contextual issues and isolation from local practices. The study attempts to provide a design framework that comprises various design models for sustainable housing, enabling architects worldwide to broaden their sustainability practices in the architectural field. The study employs the grounded theory method to transform theory into viable housing design models for architects in various regions, particularly the Middle East, who will be able to trace the regional models and select design approaches and strategies in response to local situations. The research is divided into three stages. Guy and Farmer’s six logics are linked with methodical sustainable design approaches through comparative analysis to develop design models that will be chased in sustainable housing practices. The models are introduced in the next phase within a design framework and, finally, verified through Middle Eastern practices. The framework, which has been verified by tracking sustainable housing models in the design practices of Middle Eastern countries, can be used by applying the design models individually or by combining more than one model to create more responsive sustainable design practices in the housing field. The novelty of the study is that the developed framework transforms theoretical models into viable options for designers and scholars around the world, as well as enabling architects and developers in Middle Eastern cities to easily and practically trace regional design models and to select appropriate design approaches and strategies in an integrative manner.
Present day’s products are more complex in order to fulfill the customer’s needs and legal requirements. This often leads to increasing product weight and costs and to a decrease of the available ...installation space. An approach for solving this challenge is to integrate functions into existing structures. Therefore, different strategies from differential design to function adoption are described. Taking into account function relevant questions based on module drivers, specific strategies for function integration can be chosen. The approach can be repeated for multiple applications and for different geometrical forms in order to develop new solutions for function integration.

Machine design is perhaps the most important course for Mechanical Engineering students. There are many diverse approaches to the design education in universities worldwide. This paper outlines some ...collaborative experiences for methodical design education in mechanical/industrial design engineering context at Turkish Universities. For this purpose, a case study based on a student project titled “the conceptual design of a new meatball forming machine” is utilized and the experiences of the conceptual design works made with project groups are presented. The design process outlined in this paper is based on the systematic design approach of Pahl and Beitz. The method applied includes problem definition, formulating (function diagram), creating and selecting of best design variants. The positive feedbacks received from student practices show that this work can be useful for industry followers, design lecturers and young engineers.
Science and design are two completely separated areas of expertise with their own specialists. Science analyses the existing world to create new knowledge, design uses existing knowledge to create a ...new world. This tunnel-vision mentality and narrow-minded approach is dangerous for problem solving, where a broad view on potential solutions is required to realise a high-quality answer on the defined problem.
We state that design benefits from scientific methods, resulting in a more effective design process and in better products, while science benefits from a design approach, resulting in more efficient and effective results. Our philosophy is illustrated using examples from the field of biomedical engineering.
Both methods can benefit tremendously from each other. By applying scientific methods, superior choices will be made in the design process. With design, more accurate, effective and efficient science will be performed.
