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.

The paradox that exists between the necessity of testing physical prototypes to achieve as much design criteria as possible and the desire to minimize the number of iterations at the experimental validation stage to manage development time and cost, has led the authors to develop a detailed design methodology that guides the engineers and designers through the main activities of the product development process (PDP).The numerical validation activities and the iterations performed at the detailed design phase of the PDP have become key in achieving a product that meets the client needs from a price/performance/reliability perspective. However, before starting the fabrication of a physical prototype, the multidisciplinary team must understand the issues linked to the material behavior under critical conditions of use and in relation with the range of selected processes.In previous papers, a generic methodology that takes into account several design criteria was presented. This methodology was applied to the recreational product industry with the aim of reducing the weight of a roadster frame while controlling its production cost. Specific to vehicle, fatigue and rigidity are amongst the structural criteria that are central to the safety of the user and the handling of the vehicle.The objectives of this paper are thus to outline the advantages of this methodology, show how it could be applied to the structural sub-systems and components of a vehicle, and how it could be integrated in an undergraduate project, taking into account all the design criteria established up-stream in the PDP.As this approach has already been validated in the recreational product industry, it will allow students to converge toward creative, effective but realistic solutions while providing a comprehensive feedback on the client needs.

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.
