The issue of environmental sustainability, which is unprecedented in both magnitude and complexity, presents one the biggest challenges faced by modern society. Design engineers can make significant contributions incorporating awareness into product process development. It critical that a paradigm shift design from centering on cost performance to balancing economic, environmental, societal considerations. Although there have been quite few designs for environment (or ecodesign) tools...

Design for disassembly approaches are crucial supporting industrial circular economy transition. However, a significant limitation of current design methods is their inability to model the impacts product's end-of-life status on realized effort and subsequent effects implemented strategies. To address this gap, our work proposes novel approach termed Circular Disassembly corresponding model, called Parent-Action-Child that can describe process in terms circularity index. The was tested...

Abstract Design for circular economy (DfCE) aims to systematically incorporate (CE) considerations during the design phase. In this article, we introduce an integrated quantitative framework that concurrently assesses product functionality, CE, and sustainability performance enable a more holistic DfCE. This enables coupling multiple life-cycle phase simulation models estimating effects of parameterized changes in product’s or behavior on its CE performance. We showcase ability proposed...

The rapid rise in technologies for data collection has created an unmatched opportunity to advance the use of data-rich tools lifecycle decision-making. However, usefulness these is limited by ability translate into actionable insights human decision-makers. This especially true case sustainable design (SLD), as assessment environmental impacts, and feasibility making corresponding changes, often relies on expertise intuition. Supporting sense-making SLD requires both data-driven user-driven...

Abstract To understand the past successes and future opportunities for applying Industry 4.0 technologies toward manufacturing sustainability assessment, this state-of-the-art review examines previous literature at intersection of these domains. Specifically, we focus on application in context following stages assessment: (i) planning, infrastructure development, problem definition, (ii) performance measurement, (iii) results interpretation decision-making, as well (iv) intervention,...

This paper describes a framework for applying design environment (DfE) within an industry setting. Our aim is to couple implicit knowledge such as redesign/process constraints with quantitative measures of environmental performance enable informed decision making. We do so by integrating life cycle assessment (LCA) and multicriteria analysis (MCDA). Specifically, the analytic hierarchy process (AHP) used prioritizing various levels DfE strategies. The AHP network formulated improve product...

In this paper, we explore quick 3D shape composition during early-phase spatial design ideation. Our approach is to re-purpose a smartphone as hand-held reference plane for creating, modifying, and manipulating sweep surfaces. We implemented MobiSweep, prototype application new space of constrained interactions that combine direct orientation control with indirect position via well-established multi-touch gestures. MobiSweep leverages kinesthetically aware the creation surface without...

Abstract To enable the circular economy paradigm, it is important to design easy-to-disassemble products. A new method, known as Design for Circular Disassembly (DfCD), has been proposed enhance product disassembly performances toward circularity. The method was tested on a small-sized product, showing promising results. However, its applicability medium-sized products remains unclear. goal of this article assess effectiveness DfCD products, particularly washing machines. Results showed can...

The lack of detailed process information such as part shape, setups, and efficiencies limit the accuracy life cycle inventory models that are used for estimating environmental impacts manufacturing processes. Such limitations particularly true processes additive manufacturing, where shape significantly influences resulting characteristics. To address above knowledge gap, this paper investigates influence on fused deposition modeling 3D printing. end, we experimentally measured resource...

Dysprosium (Dy) is a critical rare earth element, indispensable for realizing low-carbon technologies. A holistic understanding of global Dy supply-demand chains essential ensuring its future sustainable supply and use. This study conducts the first multiregional analysis flows stocks to comprehensively trace cycle from 1988 2021. Results show rising demand Dy-comprising intermediate final products with complex trade fluctuations since 2000. In total, 22,009 tons products, primarily as...

Reducing the environmental effects of products has become a significant focus corporate strategies. As result, easy-to-use ecodesign tools that can be implemented during early design stage are essential for corporations to gain competitive advantage in product development. A novel eco-design method, function impact matrix (FIM), is being developed as tool enable development and evaluation concepts by correlating impacts with functions. This paper aims illustrate efficacy relative ease use...

Juxtapoze is a clipart composition workflow that supports creative expression and serendipitous discoveries in the shape domain. We achieve by supporting of searching, editing, composing: user queries database using strokes, selects desired search result, finally modifies selected image before composing it into overall drawing. Serendipitous discovery shapes facilitated allowing multiple exploration channels, such as doodles, filtering, relaxed search. Results from qualitative evaluation...

A large portion of design activity involves applying previous knowledge in order to solve new problems. Therefore, facilitating eco-conscious exploration archived designs is needed for advancing sustainable product design. It thus necessary create integrated tools that share common data representations and sustainability-related metadata. This can allow designers observe covariations develop engineering intuition with regards environmental sustainability performance. In this work, we present...

In this paper, we present a novel visualization framework for product and supply chain metadata in the context of redesign-related decision scenarios. Our is based on idea overlaying product-related onto interactive graph representations its associated architecture. By coupling environmental data with graph-based visualizations architecture, our provides platform expert designers. Here, user can balance advantages redesign opportunity manage risk chain. For demonstration, ViSER, an tool that...
