Designers are increasingly involved in designing alternative futures for their cities, together with or self-organized by citizens. This article discusses the fact that (groups of) citizens often lack the support or negotiation power to engage in or sustain parts of these complex design processes. Therefore the “capabilities” of these citizens to collectively visualize, reflect, and act in these processes need to be strengthened. We discuss our design process of “democratic dialogues” in Traces of Coal—a project that researches and designs together with the citizens an alternative spatial future for a partially obsolete railway track in the Belgian city of Genk. This process is framed in a Participatory Design approach and, more specifically, in what is called “infrastructuring,” or the process of developing strategies for the long-term involvement of participants in the design of spaces, objects, or systems. Based on this process, we developed a typology of how the three clusters of capabilities (i.e., visualize, reflect, and act) are supported through democratic dialogues in PD processes, linking them to the roles of the designer, activities, and used tools.

New System

This paper addresses several issues discovered by working with different industries attempting to sustain their business enterprise and to become “Lean.” The three key points addressed by the paper are: 1) Designing a new system or re-designing an existing system should focus on collecting a complete set of customer needs and deriving functional requirements from those needs. 2) Illustrating the path-dependency or sequence of implementation of Physical Solutions (PSs) to achieve Functional Requirements (FRs) of partially coupled designs. 3) Lean is not what we implement as a system, rather lean is what we become as a result of meeting customer needs with the utilization of the least amount of resources possible in a sustained manner. When lean is viewed as a set of tools to implement, the people in an enterprise will face ever-increasing diffculty in long-term business sustainability. The primary problems arise early in the design/re-design phase due to the lack of a clear set of system functional requirements. Without clearly defined system FRs, driven by recognizing customer needs/concerns, an enterprise will implement point solutions in an attempt to improve part(s) of a system. The Manufacturing System Design Decomposition (MSDD), a product of Axiomatic Design (AD), illustrates the path-dependency among the solutions of the associated requirements of any manufacturing facility. The MSDD provides a system-wide view and a clear sequence for system design implementation. The Collective System Design approach is discussed to provide the steps for senior leadership to re-design an existing system or to design a new system that results in long-term sustainability and become “lean.”

This paper provides the formulation and description of the framework and methodology for a Durability Assessment-based Design approach for structures made of the Ultra-High-Durability Concrete materials conceived, produced and investigated in the project ReSHEALience (Rethinking coastal defence and Green-energy Service infrastructures through enHancEd-durAbiLity high-performance cement-based materials) funded by the European Commission within the Horizon 2020 Research and Innovation programme (Call NMBP 2016–2017 topic 06-2017 GA 780624). The project consortium, coordinated by Politecnico di Milano, gathers 13 partners from 7 countries, including 6 academic institutions and 7 industrial partners, covering the whole value chain of the concrete construction industry. The innovative design concept informing the whole approach herein presented has been formulated shifting from a set of prescriptions, mainly referring to material composition and also including, in case, an allowable level of damage defined and quantified in order not to compromise the intended level of “passive” protection of sensitive material and structural parts (deemed-to-satisfy approach; avoidance-of-deterioration approach), to the prediction of the evolution of the serviceability and ultimate limit state performance indicators, as relevant to the application, as a function of scenario-based aging and degradation mechanisms. The new material and design concepts developed in the project are being validated through design, construction and long-term monitoring in six full-scale proofs-of concept, selected as representative of cutting edge economy sectors, such as green energy, Blue Growth and conservation of R/C heritage. As a case study example, in this paper, the approach is applied to a basin for collecting water from a geothermal power plant which has been built using tailored Ultra-High-Durability Concrete (UHDC) mixtures and implementing an innovative precast slab-and-buttress structural concept in order to significantly reduce the thickness of the basin walls. The geothermal water contains a high amount of sulphates and chlorides, hence acting both as static load and chemical aggressive. The main focus of the analysis, and the main novelty of the proposed approach is the prediction of the long-term performance of UHDC structures, combining classical structural design methodologies, including, e.g., cross-section and yield line design approaches, with material degradation laws calibrated through tailored tests. This will allow us to anticipate the evolution of the structural performance, as a function of exposure time to the aggressive environment, which will be validated against continuous monitoring, and pave the way towards a holistic design approach. This moves from the material to the structural durability level, anticipating the evolution of the structural performance and quantifying the remarkable resulting increase in the service life of structures made of UHDC, as compared to companion analogous ones made with ordinary reinforced concrete solutions.

Clay Foundations

The present design practice for embankments on clay foundations is reviewed and its shortcomings are evidenced.A detailed analysis of field observations shows that the actual foundation behaviour differs significantly from the postulated sequence of undrained construction reponse and drained long-term consolidation. In particular a significant consolidation occurs during the very first stages of embankment construction.Design methods are reviewed and modified if necessary to account for this phenomenon. The new design approach, while largely empirical, is simpler and more reliable than existing methods.

AbstractThe wearable products market is growing rapidly. Engaging users on an emotional level may be the key to long-term use and attracting new customers. While researchers have proposed various design approaches to realize design qualities for wearable devices, emotional needs are overlooked in the design process. To bridge this gap, we developed an approach with an online tool that uses a two-axis interactive collage for users to compare and evaluate wearable products with targeted emotion-related descriptive words. This approach enabled us to explore how users perceive products and identify types of emotions that were associated with their preferences for and perceptions of the product's form and visible characteristics. The study demonstrated this design approach to reveal insights into the relationships between product characteristics and design goals, such as user comfort, user delight, and perceived product usefulness. The results showed that products that resemble clothes were perceived as more delightful and comfortable. This study suggests that the approach can be further used to explore other design concepts or goals.

PurposeThis paper aims to present an efficient design approach for the micro electromechanical systems (MEMS) accelerometers considering design parameters affecting the long-term reliability of these inertial sensors in comparison to traditional iterative microfabrication and experimental characterization approach. Design/methodology/approachA dual-axis capacitive MEMS accelerometer design is presented considering the microfabrication process constraints of the foundry process. The performance of the MEMS accelerometer is analyzed through finite element method– based simulations considering main design parameters affecting the long-term reliability. The effect of microfabrication process induced residual stress, operating pressure variations in the range of 10 mTorr to atmospheric pressure, thermal variations in the operating temperature range of −40°C to 100°C and impulsive input acceleration at different input frequency values is presented in detail. FindingsThe effect of residual stress is negligible on performance of the MEMS accelerometer due to efficient design of mechanical suspension beams. The effect of operating temperature and pressure variations is negligible on energy loss factor. The thermal strain at high temperature causes the sensing plates to deform out of plane. The input dynamic acceleration range is 34 g at room temperature, which decreases with operating temperature variations. At low frequency input acceleration, the input acts as a quasi-static load, whereas at high frequency, it acts as a dynamic load for the MEMS accelerometer. Originality/valueIn comparison with the traditional MEMS accelerometer design approaches, the proposed design approach focuses on the analysis of critical design parameters that affect the long-term reliability of MEMS accelerometer.
