Hybrid fabrication for transcended manufacturing: Flexible manufacturing system in support of the Transcended manufacturing process
Transcended manufacturing is a new emerging manufacturing paradigm in response to the rising need for mass personalisation and ultra-personalised products. Through product personalisation, people can assert their identity in an increasingly impersonal world. But the one-off a kind nature of ultra-personalised make them hard to manufacture with traditional fabrication methods. Transcended manufacturing uses automation and digital manufacturing to manufacture ultra-personalised products. Hybrid fabrication is a digital manufacturing technique that combines multiple processes to provide new process capabilities. Hybrid manufacturing is still underdeveloped but could improve the field of personalised products and transcended manufacturing with its versatility and flexibility. The project goal was to research hybrid fabrication and find and develop opportunities that may benefit Transcended manufacturing and ultra-personalised products.The project started with an analysis of the current situation of digital manufacturing and the industry. The study resulted in multiple opportunities for hybrid fabrication and transcended manufacturing, from new processes that can be used for personalised product fabrication, to versatile and flexible manufacturing. With the opportunities of hybrid fabrication defined, a future vision, a production scenario and exemplary product are created. These scenarios are used to ideate, conceptualise and develop a hybrid fabrication workstation. The future of hybrid fabrication looks bright but early adoption of hybrid manufacturing is in product research and development. The workstation is further embodied and a prototype is created to showcase and kickstart hybrid fabrication and personalised product development. The prototype addresses reconfigurability and flexibility in hybrid systems and provides a platform and framework for hybrid manufacturing. The future of hybrid manufacturing and transcended manufacturing looks promising. As the industry 4.0 grows and transcended manufacturing and hybrid fabrication mature, the new way of manufacturing ultra-personalised products can include hybrid fabrication systems.Integrated Product Desig
Cyclist Mannequin For Aerodynamics Research: Develop a cyclist mannequin from 3D scans for aerodynamics tests.
The aim of this research is to increase the speed of cyclists by reducing aerodynamic drag. Common research methods are digital and physical simulations. The goal is this project is to develop an anthropometric model for each method based on professional cyclists from Team DSM.Digital Model (Generic)The first goal of this research is to create a generic cyclist model for research organisations around the world. The Generic Model is an average of ten male, professional cyclists in both road and time trial pose (Figure 0.1). The DINED Mannequin approach is used to divide the method into four steps: Capture, Process, Correspond & Average.All participants are captured on-site on personal bicycles with two handheld Artec Eva 3D scanners. The 3D scanned data is processed in Artec Studio 12 to correct for movement and unwanted elements captured during 3D scanning. The processed model is corresponded in R3DS Wrap3 with a reference base mesh template to make them interpretable and to patch missing data. The corresponding models are averaged in Paraview to generate the Generic Model.The Generic Model stays true to the original anthropometric data of the participants where possible. However, exceptions are made where beneficial to the result. The participants are captured in the high-drag leg position with the hands separated. Shoes are digitally removed from the model. Hands, elbows and inner legs are standardizations because these sections are blocked by the bicycle. The base mesh has a resolution of 50K uniform, smoothened triangle polygons.Physical Mannequin (Personalized)The second goal of this research is to design a personalized cyclist mannequin for aerodynamics researchers. The Personalized Mannequin is the physical representation of an individual cyclist’s anthropometry in time trial pose (Figure 0.2). The Centre of Design for Advanced Manufacturing Approach is used to divide the process into four steps: Digitalization, Design Automation, Digital Fabrication & Production.The 3D anthropometric data of one of the riders captured for the Generic Model is used. Requirements for the mannequin are parametrically defined and partially applied in Grasshopper (automated) and fully applied in Blender (manually). A full-scale model of the mannequin is digitally fabricated using FDM 3D printing. Loose parts are joined, sanded, finished and assembled to complete the prototype.The requirements and design are the result of an analysis phase where users, context, interactions and competitors are researched. The creative phase structures and clusters challenges and generates solutions to them. The development phase continues with the selected concept and researches individual design features. The final design is prototyped and validated and any recommendations are made last.Rupert the Personalized Mannequin is CNC milled from rigid polyurethane foam. It is segmented near the wrists, upper arms and upper legs to apply any cycling gear. SLS 3D Printed magnetic, form-fitting interfaces attach the limbs. Rupert is mounted to the bicycle on a regular saddle, with cycling shoes to the pedals and with flexible hands to the handlebar. Rupert has the same surface resolution as the Generic Model.Integrated Product Desig
Design, fabrication, and preliminary results of a novel below knee prosthesis for snowboarding: A case report
Snowboarding with a below-knee prosthesis is compromised by the limited rotation capabilities of the existing below-knee prostheses, which are designed for use in normal walking. Based on snowboarding range of motion analyses, a novel below-knee prosthesis was designed with the aim to achieve similar range of motions like able-bodied snowboarders. The new prosthesis allows for passive inversion/eversion, passive plantarflexion/dorsiflexion and additional ‘voluntary’ plantarflexion/dorsiflexion initiated by lateral or medial rotation of the upper leg and knee. A prototype was tested on a single subject, a professional snowboarder. The results indicate that snowboarding with the new prosthesis is more comparable to able-bodied snowboarding.Biomechanical EngineeringMechanical, Maritime and Materials Engineerin
Future proofing the mold making process for Royal Delft ceramics
This graduation report presents a new mold making approach for RoyalDelft. The traditional production trajectory starts with a positive model andpouring plaster mold parts onto it one by one, producing a negative castingmold for one shape. This new proposal takes the plaster mold parts as astarting point, combining them into a modular system that can be modifiedcontinuously in order to produce many variations of a shape without startingfrom scratch for every new shape. The benefit of this approach is thatshapes such as plates, vases and boxes can be quickly tailored to individualcustomers, changing elements, adding personal texts and creating customvector reliefs.Integrated Product Desig
Towards Sustainable Behaviour in Winter Sports: a Product-Service System Design for Modular Snowboard Boots
A modular product-service approach has the potential to facilitate behaviour change within the snowboard boot context. The circular design strategy proposed in this report, including the 6 circular design principles, navigates the process of creating a product-service aiming to maintain a products’ value throughout its lifetime. With a special focus on Design for Attachment and Trust, Design for Durability and Design for Adaptability and Upgradability. Once a product-service has been established for a while, Attachment and Trust help estimate future consumer behaviour within the service. For snowboard boots in particular, Durability is defined as the main angle on sustainability to approach this project. The environmental impact of this product over a certain period is reduced by prolonging the lifetime of the product. When the value attached to a product by the user, slowly decreases over time, Adapting and/or Upgrading a product potentially renews the product value for the user. This is especially true for the functional and emotional values. This increased product value is complementary to product retention and thus longevity, the ultimate goal. What motivates users to buy certain snowboard boots depends on the type of user. A beginner has more ignorance and a lack of knowledge to overcome in their purchase decisions , resulting in a price and comfort based purchase. While an experienced snowboarder demands certain qualities or features. The different types of snowboarders are captured in four personas, including their level of investment, attitude and behaviour on the slopes. Snowboarders can identify with different personas over time, as people's needs, abilities or interests develop over time. The created lookup table regarding persona shifting can be utilised to inspire user centered design while designing the product service system. The table further elaborates on the user's perspective during persona shifting, including the user's attitude, focus and purchase behaviour (table 1). To facilitate these changes, the adaptable and upgradable aspects of the product service system should include: - the level of comfort- the stiffness or firmness- the tightening mechanism- appearance Sustainability is viewed differently among the participants of the qualitative user research. The various sustainable attitudes are independent from the snowboarder personas, which have been created from the user research data. Additionally, one's sustainable attitude is not necessarily linked to sustainable actions. Therefore, the designed sustainable, alternative product-service interaction should be superior to the current standard to avoid relying solely on benefits regarding sustainability. By doing so, an attempt is made to get both sustainable and non-sustainably behaving people on board. A market positioning analysis shows the opportunity to approach sustainability from a durability point of view. Deeluxe currently has a basis of a repair- and replaceability focussed product offering, so the transition to enter a modular system seems to be within reach compared to other brands. Deeluxe could be a pioneer in this field and potentially gain greater visibility and grow as a company, while establishing a more sustainable way of product handling. A modular product-service is proposed including a service set-up, a product-service vision and a product possibility that could enhance product longevity and stimulate the intended durable and modular behaviour. The service proposal includes the offering of separate product parts and a take-back system for repair or refurbishing of used products. The user is introduced to a different product interaction from the start, to trigger a mindset that thinks ahead. By evaluating the ease and benefits that comes with the service, the user is invited to think about their personal development as a snowboarder. Do they challenge themselves to become better? Are different product qualities demanded if so? and Do they want to explore different terrains? The threshold for trying different terrains might be lower when only one boot part has to be switched to support the rider properly. This product-service represents freedom, growth, and sustainability without compromise. The boots are high end and high performance . the user is investing in their future, without spending too much. The current standard of snowboard boots has been, re-thought, revised and redesigned in a modular fashion to prepare them for a more circular future. A possible product, the Exo-Flex, has been designed in a way that enables the user to alter the stiffness of the boot to their desires. By creating that possibility, the functional value imposed on the boots can be increased throughout a product's lifetime. Enabling the increase of a value that deteriorates over time, stimulates product retention thus creating product longevity.The Exo-Flex is especially designed for the All-in snowboarder persona, who enjoy freestyle snowboarding in the park. A form study concerning leg ergonomics and the specific movements required in snowboarding have defined the shape-design of the Exo-Flex. The main function of this prototype is to evaluate the design dimensions, demonstrate the intended use and evaluate the ease of use. The materials, the actual stiffness and structure still have to be designed and defined.Design for Interactio
