(SUPERVISOR); Gupta, Charu (CO-SUPERVISOR) Abstract: At the Kamaladevi Memorial Lecture, Chatterjee (2014) called for reimagining the future of crafts beyond patronage, toward frameworks that integrate tradition and innovation. India’s handlooms and handicrafts, representing one of the world’s richest repositories of cultural heritage and livelihoods, face systemic challenges, including market decline, policy fragmentation, and weak integration of sustainability. Mamidipudi (2018) refers to design as a strategic tool that creates value through innovative products and services, leading to positive social and economic outcomes. The study proposes, develops, and validates the Social Design Framework (SDF) to regenerate the sector by embedding heritage preservation, co-creation, sustainability, packaging, branding, and Intellectual Property as its core pillars. The framework was conceptualised through a systematic literature review that aggregated existing knowledge on the design processes adopted by designers working in the sector, the methods adopted by artisans, the challenges they face, their adaptability to markets, and sustainable practices in Handlooms and Handicrafts. The existing literature and discussions with the core group, comprising master artisans, designers, and sector experts, identified a set of attributes for the proposed social design framework. Using a mixed-method approach, combining both qualitative and quantitative methods, the research included participatory discussions, direct interviews, in-field surveys, and questionnaires distributed to diverse stakeholder groups, including artisans, designers, educators, craft experts, and funding organizations for design development in the craft sector. Some Projects like Rural Experiment, [NID-IIM- Jawaja], Operation Mojari, [UNDP-NLDP-FDDI-RUDA], Indo-Africa [DIPP, GOI - NID], Crafting Futures, [ British Council – CEPT], Design Clinic Scheme, [Min. of MSME, GOI- NID] were discussed and studied, reflecting on the process adopted and their impact. Decision-making [PMI] techniques were used to refine the framework, with valuable inputs from Artisans, Designers, and other craft experts and researchers enhancing its relevance and usability. The findings highlight both statistical significance and practical relevance, offering a roadmap for integrating Design v thinking and Universality with cultural continuity, sustainable practices, and policy reform. This research contributes to theory by operationalizing social design in craft contexts and to practice by providing a scalable, impact-driven model for artisans, designers, policymakers, and educators. The conceptual Social Design Framework proposed in this research builds on six interlinked components identified from the literature review and the mixed-method research analysis, leading to sustainable development. An info-graphic representation highlighting the key attributes of the framework, as the 7 S of the Social Design, namely Sanskritik, Sundar, Sahaj, Sasta, Samajik, Samman, and Sustainable, is developed for easy remembrance, understanding, and adaptability by all stakeholders. Three case studies validated the framework: [1] Loin loom weaving of Manipur, [2] Wooden lacquerware work of Banaras, UP and [3] Revival of Mandana – the folk- tribal art of Rajasthan. These case studies tested the framework’s adaptability, efficacy, reliability, usefulness, and accuracy. This study redefines the role of design in nation-building, moving from a creative discipline to a strategic instrument for inclusive and sustainable development. It demonstrates that the future of design in India lies not in imitation but in intelligent reinvention, empowering communities through creativity, collaboration, and cultural consciousness. This research presents a comprehensive exploration into how design can serve as a transformative tool for social, cultural, and economic empowerment within India’s craft ecosystem. 2026-04-01T00:00:00Z http://dspace.dtu.ac.in:8080/jspui/handle/repository/22717 Title: DEVELOPMENT OF A NEW PRODUCT DESIGN PROCESS TO IMPROVISE DESIGN FOR MANUFACTURING USING 3D/4D PRINTING TECHNOLOGY Authors: SOLANKI, AJAY; Singari, Ranganath M. (SUPERVISOR); Singholi, Ajay K.S. (CO-SUPERVISOR) Abstract: Three Dimensional and Four-Dimensional (3D/4D) printing has widespread popularity because of its shape-changing capabilities in various applications. 3D Printing makes only stationary structured products whereas 3D/4D printing enables an object to change its configuration in response with different external stimuli. Researchers from many fields have examined an extensive array of 3D/4D printing using proofs-of-concept. 3D/4D printing needs more advancement in the structural quality and efficiency to satisfy significant industrial applications which ensure cost effective manufacturing. An overview of integrated computation design strategies and its contribution in enhancing efficient use of smart materials in vast applications also presented and concluded with the findings like systematically incorporating sustainability variables into cost- effectiveness analyses with recent advancements in additive manufacturing tailored with human material interaction aids industries to make informed decisions that align with economic goals. Future views are critically explored and encouraging the collaboration with fabrication methods directs research efforts in a way incorporating advanced 3D/4D product design methods that satisfy industry and customer demands. Three Dimensional and Four-Dimensional (3D/4D) printing is an emerging structure creation process that allows for form morphing in response to external triggering chemicals. Many studies currently concentrate on small to medium-sized 3D/4D printing of structural components. As a result, in order to build industry-based large-scale structures, printing capabilities must be increased without sacrificing quality, cost, and speed. Advances in computer-aided design modeling have led to the development of 3D/4D products, which are essential for the large-scale manufacture of structures for various engineering purposes. Furthermore, cost-effective design and quality assurance control techniques, along with obstacles, are highlighted. Researchers previously encountered challenges in achieving high material efficiency and precise control in laser metal wire deposition, such as variability in friction, fluctuations in deposition rates, and inconsistent hardness across different scanning speeds and power settings. This research focuses on the single deposition technique within laser metal wire deposition, evaluating material usage and deposition efficiency by analysing factors like wire feed rate, laser power, and deposition speed. Findings indicate that coefficient of friction increases with higher scanning speeds, particularly at a sliding velocity of 0.5 m/sec. Furthermore, there were considerable changes in hardness and deposition rate, with the largest deposition rate occurring at the lowest scanning speed of 0.4 m/min. The research implications are significant for industries requiring complex, high-quality metal ABSTRACT components, positioning laser metal wire deposition as a key solution for modern manufacturing challenges. Supply chain management is poised for a transformative shift through the adoption of 3D and 4D printing technologies, which enable localized manufacturing, lead time reductions of up to 65%, and inventory cost savings of approximately 67%. These technologies support the growing demand for customized products by fostering a supply chain that is more responsive, adaptive, flexible, efficient, and cost-effective. 4D printing further enhances product lifecycle management by allowing objects to change shape or function over time, improving overall performance and longevity. The proposed impact analysis demonstrates streamlined adaptation of manufacturing processes, contributing to environmental sustainability through significant waste reduction. Integration of high-value design principles and additive manufacturing improved key dimensions like agility, visibility, collaboration, and flexibility by 15–20 points each, while stakeholder support remained strong, with 62.5% endorsing 3D/4D adoption, 67.8% favouring faster delivery, and over 57% supporting digital integration strategies. Conventional manufacturing methods have always been riddled with shortcomings such as wastage of material, design limitations, and added cost of manufacturing. Conventional methods fail to work efficiently with complex geometries, leading to wasteful use of material and longer production time. In contrast to this, the advent of 3D and 4D printing eliminated such shortcomings by improving design freedom, minimization of waste, and enhancing the manufacturing process. Fishbone diagram analysis is used to identifying the influences of mechanical performance, sustainability, and cost. Mechanical testing indicates hardness is up to 70.3, and young's modulus has a high negative correlation with layer height, which influences the structural integrity. Material selection is the determining factor in establishing the balance of durability, flexibility, and adaptability for optimum performance. Sustainability analysis reflects that additive manufacturing minimizes the wastage of material by nearly 30 percent against conventional means, paving the way for environmental-friendly production. Further, a cost analysis has reflected 25 percent lower production costs, so 3D and 4D printing has become more economical. The evidence points out that incorporating design for manufacturing and design for additive manufacturing boosts the efficiency, performance, and sustainability, establishing additive manufacturing as the revolutionary option beyond conventional means. 2026-04-01T00:00:00Z http://dspace.dtu.ac.in:8080/jspui/handle/repository/22702 Title: DESIGNING A MODIFIED SUSTAINABLE TRANSPORT FRAMEWORK FOR DELHI Authors: CHAUDHARI, UTKARSH; SINGARI, RANGANATH M. (SUPERVISOR); BHANDARKAR, S.L. (CO-SUPERVISOR) Abstract: The transport system in Delhi has suffered excessive pressure as a result of the fast urbanisation and motorisation that have resulted in congestion, air pollution, safety issues, social disparities and governance issues. Despite the fact that several policies and plans are associated with transport, they are not connected to such principles as holistic sustainability and global development agendas. The current doctoral study fills this research gap by developing a Modified Sustainable Transport Framework (MSTF) and an Assistive Decision-Support System (DSS) particular to the case of Delhi, and directly aligned to the United Nations Sustainable Development Goals (SDGs). The research is based on a rigorous multi-method research design coordinated around four objectives, which are: 1. Understanding the transport system of Delhi. 2. Identifying major areas of improvement in line with the SDGs. 3. Reformatting the current planning framework to develop an effective, sustainable transport system. 4. Developing an assistive system to actualise the principles of sustainability. The literature review, together with policies and best practices worldwide, provided a holistic description of the transport system, drawing on empirical fieldwork and secondary data analysis. The reason is that fourteen national- and locally based structures that transport were analysed, and the Delhi Master Plan 2041 (MPD-2041) was chosen to be evaluated. According to SDG-based indicators designed as the 5P framework (People, Planet, Prosperity, Peace, and Partnership), a systematic evaluation of 33 transport and urban planners was conducted using a Likert-scale assessment. The gaps were quantitatively analysed using mean scores and percentage agreement and were found to be critical, particularly in the domains of governance integration, multimodal coordination, nonmotorised transport infrastructure, inclusiveness, and collaborating with stakeholders. PITS-G has been designed to address the identified gaps and introduce quantifiable SDG-based performance indicators. The research also conceptualises an Assistive Decision-Support System to balance planning and implementation, comprising a unit mobility data platform, a dashboard for the policymaker, and assistive tools for the commuter. The usefulness of the framework and the strength of the system were justified by two contrasting case studies, Connaught Place and Dwarka Sector 21, where sustainability performance improved, with the greatest change in the Peace and Partnership dimension. It strengthens the relationship between the global sustainability goals and local transport planning, providing a viable understanding for policymakers, planners, and researchers on the path to achieving inclusive, resilient, and climate-responsive urban mobility systems in Delhi. 2026-03-01T00:00:00Z http://dspace.dtu.ac.in:8080/jspui/handle/repository/22683 Title: DESIGNING A FRAMEWORK FOR CONSTRUCTION AND EVALUATION OF VISUAL NARRATIVE FOR CHILDREN Authors: SINGH, SHRUTI SOHARIA Abstract: The thesis aims at creation of a framework for construction and evaluation of Visual Narratives for Children. The aim to write the thesis is to bring about a concise format, of creation of visual narratives for children. Since there are various visual narratives created for learning, understanding and educating the children. Learning outcomes vary to these types of visual narratives catering to the multiple subject matter, age group. The styles of the VN are also varying. This thesis aims as providing a clear and precise format supported by case studies. These case studies are created keeping in mind the subject matter, appropriate medium, elements of design and their response has been observed. Based on the analysis of the observations the conclusions are derived. This thesis provides a Format, based on the usage of Elements of Design and their efficacy aiming at learning and education of children. To start with the thesis in the Chapter One, first foremost is the need to define a few pivotal terms for the thesis i.e. Narrative, Visual Narrative and Storytelling. A story being told in a pragmatic manner, sequentially unfolding of events, is a Narrative. The Narrative through Visuals, the unfolding of events visually in a structural format, is a Visual Narrative. The process of telling, listening and discussing stories with others is Storytelling (England 2007). Storytelling is the art of conveying ideas, beliefs, personal experiences, and life lessons through structured narratives that elicit emotional resonance and foster deeper understanding or insight. Serrat, O. (2017). Narratives are stories created by storytellers and understood by audiences through their own experiences (Van Laer et al., 2014). Narratives are usually seen as entertaining rather than persuasive, unlike straightforward factual messages (Green, 2006, 2008; Green & Brock, 2002; Shen, Sheer, & Li, 2015). When people engage with stories, they respond both emotionally (Hamby & Jones, 2022) and mentally (Chang, 2009), which can make them more open to the story's message. This means the persuasive effect of a narrative depends less on logical arguments and more on how relatable, engaging, and immersive the story becomes (Green, 2004, 2008). Chapter Two Literature Review, defines the terminology and the key aspects of the thesis like, a story, history of stories, the role of a story, the difference between a story and a narrative, the translation of a story to a narrative to a visual narrative, Role of Visual Narrative, evolution of Visual Narratives, different frameworks of Visual Narratives, aim of VN, Learning through VN, Various psychologists and their study on the learning and development aspects among children, types of learning, learning pedagogy, Chapter Three includes the methodology design and the framework being generated. There have been frameworks, made in the field of social sciences aiming at their impact from different point of views. The literature review chapter contains the frameworks by various scholars. This chapter aims at creating a structural Framework of the Visual Narrative creation, using different Elements of Design and evaluating their Efficacy. The elements of Design (Line, Colour and Space). The VN evaluated on the basis of Engagement, Emotional Response, Curiosity achieved by the VN. The corelation between the above three attributes is established in the literature review chapter. The case studies been developed and response by children is collected, this data has been analysed and conclusions are derived to check the efficacy of the Framework. The case study: ‘Bubble extravaganza’ is a Visual Narrative talks about a very common topic among children, ie. Making Bubble and creating an open-ended narrative. Nearly all children have tried or seen this in some form. Taking such a common topic the development from a more story oriented to a process oriented VN. The Narrative and Visual Narrative is created by myself. The Narrative more focussed on the scientific process and less on the characters. The elaborate and Open- ended narrative approach, where many ways of creating a bubble were VI shown, details of the scientific phenomena are given. The exploration of the different media been used to create the VN. The efficacy of the framework evaluated by the response of the students of the age 10-12 years. The observations were made based on their response to the questionnaire, the Likert tool has been used to measure the response. The statistical evaluation makes the evidences clear. Second case study, using an existing Picture book ‘Leela’s Special Day’, of mine, open-ended in nature has been considered. The students were shown the VN and their observations were analysed. It gave a distinct result, on the basis of the shift created among the three elements of Design in the two versions of the picture book made it very evident, that students for story books, based in certain location (kerala) in this VN in a Rainy season setting described the events better in a high on colour VN contrary to the first case study in which the students responded better towards the VN with less colour and more line drawings. Third Case study, includes an existing Dynamic Visual Narrative without words. The aim to use this VN was the wordlessness, open-ended aspect, the ethnographic location of Mumbai, the stop motion animation and a life of a common family and intense and may emotions been expressed in this 10 min Wordless Visual Narrative. The students of Gurgaon 10-12 years old were shown this VN. They were made to write this story after they finished watching the movie. The evaluation was done by three experts, established curriculum and story writers for Children. Their evaluation was depicted in a statistical form and analysis has been driven out of them. Results show the children were very efficient in remembering the instances, recognising emotions, delivering the sequential comprehension of the story. Observation of students, showed their keen interest and engagement with the Visual Narrative shown. They were quite most of the time just observing the movie. Hence, this thesis throws the light on the development of a framework for further creators of books for learning, text books. The Thesis with observation, evaluations, analysis and conclusions been derived gives a concrete ground to the framework developed. It also marks the way for further research to be carried out subsequently in depth from the point of view of selected media, age group pf children, with different abilities. It is always one learning that leads to another. 2025-11-01T00:00:00Z
