Specifically, parametric design and modeling is gaining significant importance in the conceptualization of new designs and products. This communication shows some of the resulting prototypes, designed and manufactured by INNANOMAT research group (TEP 946) of Cadiz University. A product design methodology for Additive Manufacturing (AM) and functional luminaire models proposed in the scope of two projects: ADICORK and 3DBLEND. In these projects, bio-inspired texture designs were explored in natural elements and environments of the province of Cádiz, in order to highlight this region and the value of its ecosystem. In both projects, sustainable polymeric blends were developed that served as base material for the manufacture of part of the prototypes shown in this communication. For these designs, parametric design programs such as Grasshopper, a Rhinoceros plugin, were used to obtain complex models that achieve a unique and differentiating aesthetic. The result of the modeled texturing is combined with surfaces in Rhinoceros. Once the textured model is defined, it is detailed and finished in modeling programs where dimensional control is greater, and the design is adjusted to the specific AM technology chosen. In this case two were used, Fused Filament Fabrication (FFF) and Fused Granular Fabrication (FGF). \u0000Keywords: Parametric design; Fused Granular Fabrication; Additive Manufacturing; product design; Biomimicry","PeriodicalId":11386,"journal":{"name":"Dyna","volume":"51 12","pages":""},"PeriodicalIF":1.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139395875","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Safety is a human right and it should be intrinsic to the entire design process. To ensure a correct evolution of design for safety, the development of new technologies that can offer efficient solutions to current problems must be taken into account. The aim of this work is to identify a series of synergies between design and safety in order to establish a common framework between these two areas and to develop new lines of research. To do this, we start with a mind map made with the collaboration of several safety professionals and researchers, from which we identify some of the main branches of design that already have a clear connection with safety or it could be further developed. Subsequently, the previous research related to each branch and their respective applications are analysed. The work concludes with the synthesis and representation of the results in a visual and easy-to-understand infographic, that compiles the identified synergies. These results offer valuable conclusions on the synergies between design and safety, helping to identify emerging applications and new trends. In addition, the bibliographic analysis provides insight into the most developed synergies in the academic field and those new ones that may represent a research niche.\u0000\u0000Keywords: Design for safety; Graphical tools; Safety science; Industrial design","PeriodicalId":11386,"journal":{"name":"Dyna","volume":" 2","pages":""},"PeriodicalIF":1.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139392684","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Oscillating Water Column (OWC) technology is one of the most technologically developed, with the world's first grid-connected demonstration plant located in Mutriku. However, the efficiency of this technology is still insufficient for its consolidation in the energy mix. Therefore, the present work presents an advance in the increase in the extraction of energy from the incident waves through the installation of a frontal ramp that directs the wave flow towards the vertical chamber of the oscillating column. The improvement achieved will be determined by means of a CFD (Computational Fluid Dynamics) 2D scaled model, which represents the interaction of the structure with different incident wave states. Different geometric options of the ramp are analyzed in comparison with the usual vertical wall option where the phenomenon of pure reflection occurs. This work aims to contribute to improving the efficiency of OWC technology, favoring the use of wave energy as a renewable energy source.\u0000\u0000Keywords: Oscillating Water Column (OWC), wave energy converter (WEC), Response Amplitude Operator (RAO), Computational Fluid Dynamics (CFD), wave energy","PeriodicalId":11386,"journal":{"name":"Dyna","volume":" 3","pages":""},"PeriodicalIF":1.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139393338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The methodology developed and the gained experience can later be applied to other types of sport goods. The study begins with the selection and subsequent characterisation of sustainable material systems, as well as their comparison with other conventional materials. For this purpose, the mechanical properties and the damping factor of the material were analysed in both flat and tubular samples, taking into account the orientation of the reinforcement fibers. The experimental results are used in the development of the handlebar, simulating by means of finite elements the structural behaviour under the load cases established in the standard, and the vibrational response. Once this behaviour has been optimised, prototypes are manufactured using both composite materials with natural reinforcements, in this case flax, and carbon fiber reinforcements. The prototypes are tested to validate and compare the behaviour at component level and the necessary improvements are proposed in order to comply with all the specifications that this type of product must meet. \u0000Keywords: Natural composites; sustainability; vibration damping; cycling.","PeriodicalId":11386,"journal":{"name":"Dyna","volume":"30 13","pages":""},"PeriodicalIF":1.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139456539","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Particularly, on the services associated with outdoor exhibitions, which represent an interesting alternative to traditional cultural services, being accessible to all populations, at any time and without ticketing. Open-air exhibitions are usually organized using different supports but the ones with counterweights are the most popular and versatile types. Sustainability aspects of three different design alternatives are studied. In the first alternative cultural content is exposed using printed and replaceable vinyl; in the second alternative, the exhibition is illuminated and content is printed on stretched canvas. The third alternative offers an additional service because when the display panels are replaced exhibitors are transformed into street furniture. The entire life cycle of the services has been reviewed. Moreover, environmental, economic, and social sustainability dimensions have been quantitatively evaluated using, respectively, the global warming potential, the execution costs, and the working time indicators. Thus, the study contributes to integrating sustainability in the design of service systems. The presented cases illustrate the sustainability assessment methods that could be used in the evaluation of different cultural services proposals and results obtained show that different alternatives can be selected according to the criteria applied to reflect the importance of each sustainability dimension.\u0000\u0000Keywords: Sustainability, design; Service life cycle; Cultural exhibitions; LCSA.","PeriodicalId":11386,"journal":{"name":"Dyna","volume":"25 13","pages":""},"PeriodicalIF":1.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139457849","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through four different study cases of diverse medical products that match the existing categories in the established classification of standards, different design approaches and strategies are presented and suggested as feasible solutions that generate medical products. These cases studies intend to cover some categories where additive manufacturing can be used in the medical sector: a post-surgery protection cast developed using reverse engineering technologies and free-form modelling tools customized not only regarding anatomic shapes but also in terms of aesthetics, a surgical simulator that improves the surgeon’s education process in a non-expensive manner, which could also be shared and spread combining soft and hard parts, a hip surgery retractor designed together with experts that increase the performance of the commercial solutions and a bone replacement implant with an innovative approach that combines engineering polymers with metallic surface coatings. All these case studies present the diversity of possible applications when working with the medical industry, as well as the required skills and knowledge needed to start with this task. Beside this, it has been stated the convenience of engineers to work hand by hand with medical professionals, combining skills and visions to innovate and improve the patient’s journey.","PeriodicalId":11386,"journal":{"name":"Dyna","volume":"19 13","pages":""},"PeriodicalIF":1.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139455906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
