Overlapping Ergonomic Evaluation in the Automotive Design Process
- 2002
-
Konferensbidrag (refereegranskat)abstract
- Ergonomic evaluation typically comes late in the automotive design process, often not performed until physical mock-ups are produced. This may lead to expensive and cumbersome iterations, or to reductions of the final product quality due to low priority of meeting set ergonomic requirements. Computer aided design (CAD) is intensively used for design in the automotive industry. Performance and usability of computers and software are improving at a rapid pace, which enables CAD to be employed even more intensively. This encourages a digital design process where expensive, inflexible and time consuming physical mock-ups are only built at the end of the design process. This incorporates the risk that ergonomic evaluation will be put back even further. A way to address this problem is to enable ergonomics to be evaluated in the digital design process - in a virtual product. However, in many cases, evaluation made in a physical prototype is unbeatable in establishing ergonomic conditions. This paper discusses possible advantages of moving ergonomic evaluation earlier in the automotive design process by implementing planned overlapping strategies. It also shows initial results from a project at a car company, which aims at improving ergonomics integration in the automotive design process, e.g. by looking at task overlapping. These strategies are believed to be applicable both for evaluations made in a virtual environment and evaluations performed in the real world.

Predefined Manikins to Support Consideration of Anthropometric Diversity by Product Designers
- 2007

Konferensbidrag (refereegranskat)abstract
- The paper discusses the complexity involved in considering targeted product users’ anthropometric variation in multivariate design problems, such as the design of workplaces or vehicle interiors. The authors argue for the advantages of offering designers a number of predefined digital human models to incorporate in the CAD product models. A study has been carried out in order to illustrate the use of predefined digital human models in vehicle interior design by using the Digital Human Modelling (DHM) tool RAMSIS. The paper takes a designer’s view of digital human modelling and illustrates how DHM can be of great value in the design process, but also considers what implications this has on the functionality and usability of DHM tools.

- Digital human modelling (DHM) tools have been introduced in industry, mainly in automotive, aerospace and industrial engineering, to facilitate a proactive and efficient consideration of ergonomics in the design process. The employment of DHM tools in the health care sector calls for customisation work to be carried out in order to make the tools fit the design activities. The human model, i.e. the computer manikin, needs to be modified since it has the characteristics and appearance of an able healthy young or middle-aged human, but the resident or patient is frequently an elderly person with impairments of some kind. This paper suggests concepts and structures for assigning the computer manikins characteristics of the elderly. These changes are made by the modification of anthropometric and joint range of motion data in the DHM tool, and by assigning narrative descriptions to themanikins and more age-corresponding appearances. The objective is to define a manageable number of representative manikins that will support a proactive and user-centred design process in the health care industry, and in other types of design processes for the elderly, or in an inclusive design context.

Supporting 'Design for All' in Automotive Ergonomics
- 2002
-
Konferensbidrag (refereegranskat)abstract
- The automotive industry faces increasingly tough competition in a global market. One key for competitiveness is product differentiation, in order to attract clearly defined market segments. However, designing cars for specific customer groups incorporates the risk that a car appeals to only a small number of potential buyers. Another issue is that the actual customer group in many cases differs fromthe initially targeted customer group. The use of the ‘design for all’ (DfAll) concept may very well enlarge a car manufacturer’s market and improve the vehicles by making them suit larger populations. This paper discusses the aims of a research project that seeks to identify areas where both the main targeted customer group andothers can gain from a ‘design for all’ approach. Other objectives are to suggest working methods that enable ‘design for all’ in the automotive development process and the identification of computer tools, such as virtual manikins, that can support these objectives early in a virtual design process.

- Computer aided visualization and simulation enables early assessment of important design parameters of future products and production systems. Typically, humans affect the system performance, and in order to achieve the expected system efficiency ergonomics needs to be considered in the design process in addition to the more technical or logistical matters. Hence, there is a call for ergonomics to be a natural part of the product and production system design process, also at virtual stages. This paper portrays and discusses two cases where company-specific ergonomics guidelines were implemented into digital human modeling systems for performing static work analyses. Albeit useful, the approach of evaluating static postures gives a reduced picture of the actual situation since the work usually involves a series of movements and tasks. A recently commenced research project aims to enhance knowledge on how to estimate accumulated ergonomic load over time. This knowledge is eventually to be implemented in DHM tools to support objective ergonomics analysis of complete work sequences in virtual environments.

Use of characters and scenarios in gear shift design
- 2003
-
Ingår i: DPPI '03. - New York, NY, USA : Association for Computing Machinery (ACM). - 1581136528 - 9781581136524 ; , s. 140-141

Konferensbidrag (refereegranskat)abstract
- The employment of the design methods of characters and scenarios in the conceptual design of a gearshift system for future automobiles is presented. The main objective for the project was to provide design suggestions for a gearshift system that people will appreciate in future cars in view of market trends, technology developments and environmental demands. The methods were tested for concept evaluation at a Swedish car component manufacturer. The methods gave rough, but important, indications of possible appreciation and acceptance of design proposals, and assisted consideration of user diversity. This low-cost approach is sufficient for evaluation purposes at early design stages, but may be complemented with more thorough studies if time and money permits.
