The constantly increasing customer requirements as well as the shortening of development and innovation cycles of future vehicle models presents the automotive industry with a great challenge. In order to continue to exist in established markets and to expand into new markets, agile, target-/user-oriented and economic product development is necessary. In addition to changes in global sales markets, compliance with new environmental regulations is another challenge for the automotive industry. In particular, the introduction of electric drive technologies into existing module or modular strategies is a task to be solved. The variety of different vehicle models also increases the complexity of the product and development costs, too. One measure to reduce complexity in the automotive industry is the use of common parts. Through a platform, module and series strategy, the costs and development time of a vehicle model can be reduced. The common part strategy as well as the scalability of a component is discussed in more detail using a hydrogen pressure accumulator. Based on the approach for the design and evaluation of the hydrogen tanks, the system properties, such as volumetric or gravimetric density, can be derived and the influences of the assemblies can be taken into account. For a goal-oriented design of a pressure accumulator with application-specific innovative design (shape and hybrid structure), an analysis of the interrelationships of features is required. By means of a parameter study of different vehicle models, the influence of characteristics on the properties of the pressure accumulator and on the system properties of the chassis assembly can be derived. However, in order to achieve the defined requirements for the component, a target-oriented adaptation in the course of vehicle development is necessary. The created approach serves for a quantitative evaluation of different scenarios in the course of the product development process under shows recommendations for action
