Abstract Joining technologies have a crucial role in the product development process, e.g. to achieve local part properties or functional integrations. This often requires multi-material joints, which are challenging for conventional joining processes. Therefore, innovative processes are needed to generate bonds between adhesion-incompatible material combinations, such as joining using pin-like structures in the vibration welding process. Investigations into this novel process have provided initial findings; however, a specific pin design is not possible at this time. For this reason, the influence of the pin-foot width of the two joining partners was analyzed numerically by simulation. The results of the simulation were validated by experimental tests. The investigations show, that the simulation model is suitable for predicting the bond quality as well as the fracture behavior of the multi-material joint based on pin-like structures. The developed correlations between material, pin-like structure, and resulting bond quality allow design criteria for the pin-like structures to be derived. These allow a specific dimensioning of the pin-foot ratio depending on the used material combination. Thus, for example, the fracture behavior of the multi-material connection can be selectively adjusted, as well as the bond strength can be maximally utilized.

The recent increases in gasoline price have initiated a new thrust to reduce vehicle weight, hence creating a new market opportunity in the recreational product industry. At the same time, integration of both optimization and validation at the detailed design phase into the product development process has become key to achieving a product that meets the client needs from a price/performance/reliability perspective. Such integration also leads to more accurate requirements regarding the behavior of the structural components of a recreational vehicle. Therefore, to reach the objective of a weight reduction for the structural subsystem in a three wheels roadster project, a methodology that optimizes both frame geometry and material properties according to the following types of design criteria has been developed: - Structural criteria in order to support the specified loads;- Weight and cost criteria to assess some performance and market targets;- Qualitative criteria such as aesthetic, assembly or manufacturing. One of the objectives of this paper is to outline a design and validation methodology that could be applied to the structural sub-systems of a recreational product with regard to all the design criteria established up-stream in the product development process. This approach will converge into a creative, effective and profitable solution and will allow designers to offer a feedback on the client needs. The optimization process that the approach entail allows finding one or more combinations of parameters maximizing or minimizing a given design criterion, while the validation activities provide feedback to the designers in order to verify the calculations accuracy and the respect of all design criteria. According to the nature of the load cases identified, the proposed methodology has been applied to design and validate the frame of a three wheels roadster as part of a challenging multidisciplinary project involving students, professors and engineers from the recreational products industry.

An accurate understanding of users' needs is essential for the development of innovative products. This article presents an exploratory method of user centered research in the context of the design process of technological products, conceived from the demands of a large information technology company. The method is oriented - but not restricted - to the initial stages of the product development process, and uses low-resolution prototypes and simulations of interactions, allowing users to imagine themselves in a future context through fictitious environments and scenarios in the ambit of ideation. The method is effective in identifying the requirements of the experience related to the product’s usage and allows rapid iteration on existing assumptions and greater exploration of design concepts that emerge throughout the investigation.

There are many roles that design can play in organisations. It can be source of good marketing strategy, and designer by himself can be a promotional tool for a company. Thanks to those actions companies can gain publicity, media attention and good PR.On the second level, design can be perceived as ‘process of making things better’. In this case companies can achieve more effective product development process, new tools and technologies.On the third level we have the situation when designer work alongside with company managers with the whole business concept. At this level, designers’ work looks more like a brand consultant, a strategist. In this approach design should be reflecting certain brand name and brand values.As our study presented, Swedish companies operate on those two, higher levels, while Polish still limit the scope of design. We strongly believe, that Polish companies, as they gain more experience with design activities, will be more likely to perceive design in this more mature approach. In the meantime, presenting best practices from companies from other, more mature countries could be a good way of promoting design as a strategic asset rather than promotional tool. We believe that in order to fasten this process, Polish companies should as follows:1. Work more often with external and foreign designers;2. Expand the area of designer responsibilities in companies;3. Place the responsibility for design in hands of professional design managers.
