It is therefore important to appropriately integrate the analyses activities in the product development process. One important aspect of this integration is how to handle the initiation of the task: identifying the need, planning the task and its monitoring, and communicating it to the analyst. To that end, this paper proposes and illustrates a product development process model that aims to efficiently and effectively prepare a design analysis task.

The properties of these new materials are expected to result in improved ergonomics, energy savings, increased flexibility and more robust equipment, which in the end will result in enhanced productivity. Carbon composite materials are one such alternative that has excellent material properties. These properties are well documented, and the market for carbon composite materials is growing in many areas such as commercial aircrafts, sporting goods and wind turbines. However, when studying the use of carbon composite materials for production equipment in the automotive industry, it was found that there were few, if any, such examples. 2 Copyright © 2013 by ASME composite material represents a favorable alternative to conventional materials, as the system combines superior properties without significantly increasing the cost of the equipment. This paper describes the approach in detail.

Since all of these tools require a certain level of expertise in order to be successfully utilized in industrial practice, the types of analyses performed by the engineering designers are confined to simple, straightforward ones.

CBDA refers to quantitative design analyses utilising computational tools in the engineering design and development of technical solutions. There are currently limited insights into and knowledge of tools and methods needed to facilitate the use of CBDA by engineering designers. In order to gather information on this aspect of CBDA, an industry survey has been performed. 77 persons completed the survey (16% affiliated to NAFEMS) open for twelve weeks during October-December, 2014. Around 35% answered that within their companies CBDA is used by engineering designers, and 28% of those who are not currently doing so expect to do so in the future. Linear static analysis is the most frequent type of analysis performed by engineering designers. The benefits put forward by the respondents in favour of involving engineering designers in CBDA are: it allows early evaluation of concept candidates, shortens lead time, frees resources for the analysis department, and reduces costs. 26% of the respondents answered that there is resistance from the analysis department against allowing engineering designers to perform CBDA, 19% within the engineering design department are also against this involvement and 26% answered that there has been no problem associated with this involvement. Even though the engineering designer performs CBDA on his/her own, supervision (56%) and quality assurance of the analysis results (59%) is the responsibility of the design analysts. This is also the case regarding the development of tools and methods to be used by the engineering designers as well as instruction and training of the engineering designers.

If engineering designers have to send every solution candidate to a design analyst, a lot of time and money is lost. To avoid this, some Swedish companies have started to allow their engineering designers to use the analysis capabilities imbedded in modern CAD/CAE software.

From a research project with the objective to develop a computer-based design system for the design of lightweight grippers, one of the major difficulties was to overcome the system users' lack of knowledge and experience in the design of lightweight structures and Computer-Based Design Analysis (CBDA). CBDA here refers to the use of analysis tools such as Finite Element Analysis (FEA) and computer-based structural optimization. In order to handle these difficulties, the author introduced the use of templates. In the given context, a template refers to an especially preformatted code, which contains the implemented information/knowledge necessary to perform a specific task on an operational level. It should be noted that the use of templates as a means of support in performing a specific design or analysis task is not a new phenomenon in industrial practice. Inspired by the opportunities provided by the template approach, the main objective set out for the thesis project was to facilitate the active participation of the engineering designers in performing CBDA singlehandedly, or in any other organizational setting, by utilizing a Template-Based Design Analysis (TBDA) approach, as an integrated part of their activities within the engineering design process. The evolutionary research approach for the development of the TBDA approach is based on surveys in Swedish as well as international industry, literature surveys, the development of a Generic Design Analysis (GDA) process model (facilitating integration of the activities between CBDA and engineering design) and a number of demonstrator projects to deepen the insights into TBDA. Note that as the TBDA approach is intended for use in industrial practice, the approach is independent of specific engineering design and product development processes utilized in industry. The conclusion of the thesis work clearly supports the claim that TBDA is not only a competitive approach to current alternatives in supporting the engineering designers performing CBDA, but also of a complementary nature providing functionality not included in the alternative approaches currently used in industrial practice.

These processes, methods and techniques, are usually not explicitly expressed in terms of directives as to when and how they are to be used in the actual design of the product-to-be. An important goal in product development of today is to fulfill the terms for sustainable development, thus emphasizing the need to develop products which are not overexploiting the available resources provided by nature. By utilizing an approach to development and design based on bionics, i.e. utilizing biological methods and systems found in nature as a means of creating technical solutions, a conceptual framework is provided which is especially fit to accommodate the striving for sustainability. Striving for lightweight designs provides a signi...

Method development, that is the development, verification and validation of specific guidelines, procedures or templates for the design analyst and/or the engineering designer to follow when performing a design analysis task. A design analysis process model needs to be able to deal with at least these four. In this work, a process model named the generic design analysis (GDA) process model, is applied to these four contexts. The principles for the adaptation of the GDA process model to different contexts are described. The use of the GDA process model in these contexts is exemplified with industrial cases: explorative analysis of design parameters of a bumper beam system, the final physical acceptance tests of a device transportation system (collision test, drop test, vibration test), and the method development of a template for analyzing a valve in a combustion engine. The "Evaluation" context is not exemplified as it is the most common one in industry. The GDA process model has been successfully used for the four contexts. Using the adaptation principles and industrial cases, the adaptation of the GDA process model to additional contexts is also possible.

The main challenges are that parts and processes are becoming more and more complex, which requires designing novel or complex dedicated fixtures, and that, for one given flexible fixture to be replaced, several variants of such dedicated fixtures must be designed to hold a variety of individual parts, without causing increased costs and delays. The systematic fixture design method and computer-aided fixture design system (CAFDS) developed and applied for the presented industrial case - novel design of a lightweight (carbon fibre composite) robot gripper - is a possible approach to addressing these issues.
