Abstract

Companies face pressure to enhance productivity and efficiency while meeting the demands of dynamic markets and global competition. Additive Manufacturing (AM) technology has emerged as an innovative solution with the capability to efficiently create complex geometries and enable design personalization, despite ongoing challenges related to quality, materials, and post-processing. The TRIZ method, as a systematic problem-solving approach, offers innovative solutions by analyzing contradictions in design, which can be applied to AM to optimize processes and products. The Design for Additive Manufacturing (DFAM) approaches leverages AM's layer-by-layer production process to create new, innovative designs. In the context of Concurrent Engineering (CE), the synergy between CE, AM, and TRIZ enables more efficient, innovative, and rapid product development, providing design flexibility, lower production costs, and shorter time-to-market. This combination of strategies offers a significant competitive advantage in the global market.

Abstract

Lean manufacturing is a systematic approach to reduce waste and increase productivity. In its implementation, lean manufacturing is often faced with complexity in its application due to inappropriate decision-making. Therefore, a more structured approach, such as the integration of the Fuzzy Multi Criteria Decision-Making (FMCDM) method, is a solution to assist decision-making within the lean framework and ensure proper lean implementation. This research aims to explore the application of FMCDM by using a Systematic Literature Review (SLR) approach, successfully analyzing 185 articles published between 2000 and 2025 focusing on integrating FMCDM and lean manufacturing. The results of the literature review show that the integration of FMCDM and lean manufacturing is still limited but has increased since 2023, with FMCDM being used for three primary purposes, namely evaluation of factors and risks in lean implementation, selection of appropriate lean tools and strategies, and assessment of lean level. This research identifies research gaps and offers practical recommendations to improve lean manufacturing effectiveness through a more adaptive and structured decision-making approach. Thus, this research is expected to significantly contribute to developing lean manufacturing theory and practice, particularly in FMCDM-based decision-making.

Abstract

Product design has emerged as a crucial element in developing innovative solutions that prioritize not only functionality and aesthetics but also sustainability. The Human-Centered Design (HCD) approach has long been employed to ensure that user needs remain the primary focus throughout the design process. However, global challenges such as climate change, social inequality, and the long-term impacts of products necessitate a more comprehensive approach. Consequently, the concept of Humanity-Centered Design has been developed as an extension of HCD, emphasizing the importance of considering the entire ecosystem, other living beings, and long-term consequences in the product design process. This research utilizes a narrative literature review method to examine the Humanity-Centered Design (HuCD) approach within the context of sustainable product design. The review findings indicate that Humanity-Centered Design introduces five key principles, which include a focus on fundamental issues, a holistic ecosystem perspective, long-term outlook, continuous iteration, and community participation. This approach has been shown to enhance the relevance, acceptance, and sustainability of solutions across various sectors, including health technology, manufacturing, and digital domains.

Abstract

This study aims to redesign the cheek retractor to enhance patient comfort and clinical efficiency, reducing soft-tissue trauma caused by poor fitting and material rigidity in conventional devices. A two-phase Quality Function Deployment (QFD) approach was applied involving ten dentists to identify user needs. Phase I (House of Quality) translated these needs into technical characteristics, while Phase II mapped the prioritized characteristics to critical components for design improvement. The results showed that QFD Phase I prioritized technical specifications such as product weight and mechanical strength, whereas Phase II prioritized the structural material and the width adjustment mechanism. The improved design utilizes durable PC/ABS material capable of repeated sterilization, effectively reducing tissue trauma, increasing comfort, and providing adjustable fitting for various oral anatomies. Overall, this study offers an innovative, QFD-based framework that directly links the voice of the dentist to engineering specifications to develop ergonomic and user-centered medical instruments.

Abstract

This literature review examines the application of methods such as Life Cycle Assessment (LCA), Design for Environment (DfE), Cradle to Cradle (C2C), Biomimicry, Circular Economy, and Sustainable Material Selection (SMS) in Sustainable Product Design & Development (SPDD). This study aims to synthesize existing research on the benefits, challenges, and integration of methods for environmentally sustainable product design through a narrative literature review of academic sources from 2008 to 2025, including textbooks and journals such as the Journal of Cleaner Production. The findings highlight that these methods collectively reduce environmental impacts by up to 70%, enhance resource efficiency, and foster innovation. However, challenges such as high implementation costs, data scarcity, and scalability issues persist. This review argues that an integrated framework combining LCA, DfE, and Circular Economy effectively mitigates these barriers by streamlining data requirements and optimizing long term cost efficiency through proactive design. Consequently, this integrated approach offers optimal outcomes for sustainable product development while supporting global regulations. Future research should prioritize empirical studies and interdisciplinary collaboration to further bridge the gap between theoretical frameworks and practical application.
