Author(s):  
Maryanne Townes

Traditionally, the ergonomics engineer has not played an active role in the design of jigs and fixtures used to manually assemble parts. This is problematic, since tool redesigns are often infeasible due to cost and production constraints. Therefore, less effective measures must be used to control ergonomic hazards, since the hazard(s) cannot be engineered out during the design process. References, guidelines and checklists used by many tool designers do not include ergonomic engineering principles and methods. In addition, many ergonomics engineers may not be schooled in the elements of jig and fixture design, which may reduce their effectiveness as part of the tool design team. The purpose of this paper is to provide the ergonomics engineer with an overview of the design process, and proffer guidelines to assist in the review of jig and fixture designs.

Stir was a crowd-voted grants platform aimed at supporting creative youth in the early stages of an entrepreneurial journey. Developed through an in-depth, collaborative design process, between 2015 and 2018 it received close to two hundred projects and distributed over fifty grants to emerging creatives and became one of the most impactful programs aimed at increasing entrepreneurial activity in Canberra, Australia. The following case study will provide an overview of the methodology and process used by the design team in conceiving and developing this platform, highlighting how the community’s interests and competencies were embedded in the project itself. The case provides insights for people leading collaborative design processes, with specific emphasis on some of the characteristics on programs targeting creative youth

AbstractAs design research expands its horizon, there has been a recent rise in studies on nontraditional designers. Previous studies have noted the positive effect of diversity in generating ideas. Among different sources of influence, peers outside the design team have been noted for their positive impact on the design process, yet the research on this topic is still in its early stages. Using qualitative data from 40 small and medium-sized enterprises (SMEs) in the American and Finnish food and beverage industries, the current study examines their interactions with other SMEs, shedding light on the influence of peers on creating new design solutions. The findings suggest that peer companies can act as a frequent and impactful source of inspiration for product design ideas. The most prevalent forms of interaction were co-creating products, sharing information, and sharing ingredients. Furthermore, the interactions were voluntary, organic, and improvisational in nature, and physical proximity or previous connections often initiated the interactions. Taken together, a great number of peer influences contributed towards creative new solutions.

Human-Centered Design focuses on the analysis, specification and involvement of a product's end users as driving elements in the design process. The primary research objective of the case-study presented in this paper is to illustrate that it is essential to include users with special needs into all major steps of designing a web-portal that provides services to these special users. But how can this be accomplished in the case of users with special cognitive and affective needs? Would the “classical” Human-Centered Design Process (HCD) be sufficient or would it need to be adapted and complemented with special procedures and tools? In this paper the design team shares the strategies they adopted and the experiences they gained by including users with dyslexia in the design of the LITERACY Web-Portal. Besides providing insight into the special effort and steps needed to adapt HCD for users with special needs, the paper encourages application designers to include end-users even though - or particularly because - they have needs that are special and critical for the adoption of the product.

The purpose of this study is to develop a database for checking fixtures for automotive parts. The parts used in the fixture checking process were automotive parts such as clamper, stand and toggle. The goal of this project is to implement a database of checking fixtures parts. The project started with identifying the current problems that were faced by the designer at a design department, in a support service for automotive industries. Idle time has been the major problem that designer have to faced. All the data and information related to this project has been sought and explored in the literature review. Catia software is used as the CAD software to construct three-dimensional models for the design of all the parts in the parts library. All the parts are organized in three different sizes which are determined by the size of car body panel. Referring to the result, new libraries were developed and created using the Catia software to aid designers in the checking fixture design process. The validation of the new libraries had been conducted with the company’s design engineer to test the effectiveness, usability and relevancy. In summary, this database and method can potentially accelerate the checking fixtures design process to be faster and more efficient.

Integral Building Design is done by multi disciplinary design teams and aims at integrating all aspects from the different disciplines involved in a design for a building such as; archtitecture, construction, building physics and building services. It involves information exchange between participants within the design process in amounts not yet known before. To support this highly complex process an Integral Building Design methods is developed based on the combination of a prescriptive approach, Methodical Design, and a descriptive approach, Reflective practice. Starting from the Methodical Design approach by van den Kroonenberg, a more reflective approach is developed. The use of Integral Design within the design process results in a transparency on the taken design steps and the design decisions. Within the design process, the extended prescriptive methodology is used as a framework for reflection on design process itself. To ensure a good information exchange between different disciplines during the conceptual phase of design a functional structuring technique can be used; Morphological Overviews (MO). Morphology provides a structure to give an overview of the consider functions and their solution alternatives. By using this method it is presumed that it helps to structure the communication between the design team members and a such forms a basis for reflection on the design results by the design team members. This method is used in the education program at the Technische Universiteit Eindhoven and was tested in workshops for students and for professionals from the Royal Institute of Dutch Architects (BNA) and the Dutch Association of Consulting Engineers (ONRI). Over 250 professionals participated in these workshops.

Current reverse engineering approach is an effective way for technology progress of developing countries. Based on analysis of existing reverse engineering technology, a new concept of Product Reverse Engineering (PRE) is proposed and its theoretical framework is discussed first in this paper in order to extend its application from components to the overall product structure and design process. Then a brief introduction is made to the technical system architecture and key techniques for PRE, which include the rapid solid modeling, integrating with existing CAD systems through STEP file, assembly modeling for conceptual structure, and reverse design process reconstruction. Finally, a prototype system PRE-DARFAD is developed with initial verification by a fixture design example.

AbstractUser-centered approaches to design can guide teams toward an understanding of users and aid teams in better posing design problems. This paper investigates the role of user-centered design approaches in design process and outcome within the context of design team projects. The value of interaction with users is examined at several stages throughout the design process. The influence of user-centered design on the performance of design teams is also explored. Results suggest that the quantity of interactions with users and time spent interacting with users alone is not linked with better design outcome, but that iterative evaluation of concepts by users may be of particular value to design prototypes. Suggestions are made based on the reflections from the authors after conducting this study.

Psychological interactions among members of a systems design team are frequently of major importance in the design process. Problems arise from specialized design interests as well as failure in systems discipline. Such problems can be resolved only by understanding the nature of the individual and his involvement in interpersonal design conflicts. Several areas may be considered for improving interpersonal relations in the systems design effort. Through increasing emphasis on significance of systems design, greater personal and professional involvement in the systems approach may be possible. Attention is required at the corporate-management organization level to orient individual engineering professional goals in terms of total system perspective. Indoctrination and discipline in systems philosophy and practices also require increased emphasis. Comprehensive design-team training might be considered as a means for improving the systems design process. Further study is suggested.
