Enhancing Access to Water in Mexico City and Its Peri-Urban Area Through User Centered Design
Volume 6: Design, Systems, and Complexity, 2021
Lack of water in Mexico City and its peri-urban area has been an increasingly worrying matter in ... more Lack of water in Mexico City and its peri-urban area has been an increasingly worrying matter in the last few years and has been addressed through multiple government and NGO initiatives such as supplemental delivery via water trucks, rainwater harvesting, intermittence in water services and pipeline network maintenance. However, the rapid and unstructured development of the urban spot has exacerbated the problem, rendering these solutions ineffective. Due to the complexity of the problem, solutions may be more impactful if they focus on fixing or creating effective interactions among the elements of the system — interactions in which the main element is the user. This paper presents a design proposal created from the observations made in Mexico City. Design Thinking was used by understanding the users’ needs and the interactions between the agents through three main phases: Approach and definition of the problem, Prototyping stage and Final proposal explanation. The proposal and re...

Even more, it is a common activity of programmers, who make a decision in this regard every time a milling and drilling operation is performed. This research is focused on better understanding the power behavior for face milling and drilling manufacturing operations, and the methodology followed was the design of experiments (DOEs) with the cutting parameters set in combination with toolpath evaluation available in commercial software, having as main goal to get a predictive power equation validated in two ways, linear or nonlinear, and understanding the energy consumption and the quality surface in face milling and final diameter in drilling. The results show that it is possible to find difference in a power demand of 1.52 kW to 3.9 kW in the same workpiece, depending on the operations (face milling or drilling), cutting parameters, and toolpath chosen. Additionally, the equa...

This reference framework is based on the Integrated Product, Process, and Manufacturing System Development Reference Model (IPPMD). The IPPMD will permit the integration between the different engineering domains that comprise the S 3-Product (mechanical, electrical/electronic and software engineering). Therefore, the framework proposed provides a set of stages, activities, and tools in order to guide designers in the S 3-Product realization process. The main objective of this work is to fill the lack of the design roadmaps that permit the realization of this new generation of products. A development of a S 3-Microfactory as CPPS is presented as case study.
Product re‐engineering process using an enterprise modelling architecture
International Journal of Agile Management Systems, 2000

The product re-engineering process is a new approach to the realisation of substitute components without the benefit of original design process documentation or any other documentation relating to the component. Re-engineering comprises stages which are potentially applicable to many industries. This research applies an enterprise modelling architecture to modelling the re-engineering process, producing descriptions of the process from several different descriptive views, namely function, information, resource and organisation. This results in a more complete description of the process, in which the model itself may be used as a reference for the implementation of a re-design process in a particular company. This research also shows how the information modelling constructs of CIMOSA can be used to meet the particular unique requirements of the process of re-design.

For those related to design and development in universities, research institutes and companies it is a fundamental issue to recognize features and details of the sustainability assessment tools in order to select the one that best fits their particular needs. This paper describes the outcomes of a product sustainability assessment carried out at Universidad Nacional Autónoma de México, UNAM. The approach followed by the authors in this assessment was aimed at comparing the results provided by a set of software tools and a previous sustainability integrated-criteria tool developed by the research group. The main contribution of this paper is the insight on the software tools used and on the results of the assessment since the design point of view. The results of the assessment included metrics such as: carbon footprint, energy use, end of life potential, toxicity, eco-toxicity, human toxicity, recyclability, and others. In the first part of the paper, an introduction of the criteria and the software based tools for sustainability assessment used by the authors is presented. Then a justification of the tools used and an explanation on how the comparison was achieved are given. The product used as a case study and the results of its sustainability assessment are presented. The case study part is a home appliance subsystem. In the end of the paper conclusions, insights and further work are given

A Case Study in “Total Beauty” Design: An Experience Through Sustainable Product Design
Volume 5: Energy Systems Analysis, Thermodynamics and Sustainability; NanoEngineering for Energy; Engineering to Address Climate Change, Parts A and B, 2010
ABSTRACT Recent research on ‘engineering design’ is expanding to consider methods, tools and fram... more ABSTRACT Recent research on ‘engineering design’ is expanding to consider methods, tools and frameworks aimed at assisting designers in the process of developing sustainable products. Some of these new approaches highlight the importance and advantages of applying biology, chemistry and human-environment health, concepts and principles at the design stage of the product development process. The successful application of these approaches also requires overcoming a number of challenges. Two particular issues currently being investigated are: 1) the contradictory and sometimes misleading use of concepts regarding what a sustainable product is; and 2) the lack of sustainable parameters to evaluate how sustainable a product is. This paper presents a synthesis of the Total-Beauty theoretical framework, based on the study reported in a previous paper. Then, a process to redesign products using BioThinking, is proposed followed by its application in the redesign of a product. The process is original because it shows how the core concepts are considered in all the steps of a design process and not just in the specification and evaluation steps. The redesign is used as a case study to show its utility. The paper includes the synthesis of evaluation parameters based on BioThinking to both assess the sustainability of products, and compare the redesigned product against the original design. In the end of the paper, a discussion of the design process and the results of the case study will be presented.

Manufacturing resources must be selected to fulfill product design specifications and production requirements. One particular case of determining resources is the configuration of machine tools, as it includes the selection of the required machine tools and the corresponding cutters, fixtures and operation conditions. This paper describes a machine tools configuration process and a software application based on information models to assist it. The process has been devised to concurrently select resources and determine operation conditions, emphasizing the close relationship that exists between them and to guarantee their compatibility. The information models represent product and manufacturing data, and capture suppliers catalogues information. The software applications employ neural networks to select manufacturing process and resources, and genetic algorithms to determine operation conditions...

These models are implemented in databases aimed at providing information to software applications that assist the concurrent design of products. This paper presents the specifications of data models to assist the concurrent design of injection plastic parts and their moulds. The product models are original since they capture part and mould life cycle aspects using the same data structure. The models also link product functional information to the design process and consider the capacities of an injection machine. The paper introduces the underlined structure of the above mentioned data models and uses a case study to show their capabilities. Finally, some conclusions are presented.

Volume 1: 15th International Conference on Advanced Vehicle Technologies; 10th International Conference on Design Education; 7th International Conference on Micro- and Nanosystems, 2013
ABSTRACT This paper documents the process, the outcomes and the lessons learned from a series of ... more ABSTRACT This paper documents the process, the outcomes and the lessons learned from a series of two design courses aimed at incorporating environmental, economic and social concerns during product development and focused in the development of products that address issues related to the above subjects. These courses are co-taught by professors of the Engineering and the Industrial Design Schools of the Universidad Nacional Autónoma de México (UNAM). Each course lasts one academic semester and includes engineering graduate and undergraduate students from industrial design and engineering. The two courses developed were titled New Product Development (NPD) and Design for Sustainability (DS). The NPD course runs in collaboration with the University of California Berkeley (UCB) and it has been taught at UNAM since 2008. At UCB the course has jointly been given for more than ten years by faculty of the Department of Mechanical Engineering and the School of Business. This course teaches the design process based on a user centered design approach for proposing new product concepts. The course fosters the development of product concepts that address particular user needs related to sustainability issues and enhance user´s experience and innovation. NPD also covers topics that include environmental, economic and social concerns in the product development process. The DS course is aimed at introducing students with the most representative approaches, methodologies and tools related to sustainability. DS takes as a background the NPD process, covering the following product development activities, i.e. takes the NPD product concept produced by students and evaluates its environmental impact, and its technical and economic feasibility. Some issues on entrepreneurship and social responsibility are also covered. This course was devised considering the broad UNAM students’ profiles and the current opportunities for developing new products in Mexico. For both courses design projects are paramount. Some of the projects carried out by the students during the courses are proposed by themselves and others are put forward by collaborative companies linked to one of the Faculties of the UNAM.

The team, who is composed by faculty from the School of Engineering and the School of Architecture, coordinates with pairs of Stanford University, the University of California at Berkeley, and the Technical University of Munich; to teach three particular design courses.All three courses are related to product innovation but they have different emphasis depending on the collaborating partner. The focal points of each of the three courses are: (1) innovation, (2) user centered design and sustainability and (3) transport in megacities of the future.Engineering and industrial design students are involved in the courses. They are organized in teams that include participants from the two collaborating universities. During the courses teams carry out projects working mostly at a distance; they use different means of communication and information sharing and also pay reciprocal visits between the universities involved in the collaboration.This paper describes each of the three courses highlighting their particular characteristics. The outcomes and results of the courses and specific projects are commented. In the end of the paper lessons learned are discussed and final remarks are presented.
