The challenges of lightweight design are not only the development of new materials and production technologies but above all the consideration of lightweight design potential in the early phases of product development. This early consideration allows the product developer to control the resources towards a lightweight solution. However, this resource-efficient lightweight design development only works purposefully if product and company-specific criteria are used for the potential analysis. In addition, by considering potentials for mass redistribution, it is possible to uncover even more lightweight potentials and achieve lightweight design goals that are only achieved inefficiently or even not achieved by a mere mass reduction. Current methods only insufficiently support the product developer in facing these challenges.The purpose of the present application is, on the one hand, to gain a deeper understanding of the most diverse motivations and criteria for lightweight design, and, on the other hand, to understand the reciprocal effects of mass reduction and mass redistribution goals. As a result, based on the findings, two methods will be developed that support the product developer in the multi-criteria mass reduction and mass redistribution. Both methods should be combined into one methodology, taking into account the basic research. This will finally be validated in several case studies in cooperation with industrial partners.

轻量化设计的挑战不仅在于新材料和生产技术的开发，更重要的是在产品开发的早期阶段考虑轻量化设计的潜力。这种早期考虑允许产品开发人员控制资源以实现轻量级解决方案。然而，这种资源高效的轻量级设计开发只有在产品和公司特定的标准用于潜在分析时才有目的地起作用。此外，通过考虑质量重新分配的潜力，可以发现甚至更多的轻量化潜力，并实现轻量化设计目标，这些目标只能低效地实现，甚至不能通过仅仅减少质量来实现。本申请的目的一方面是更深入地理解轻量化设计的最多样化的动机和标准，另一方面是理解质量减少和质量再分配目标的相互作用。因此，根据研究结果，将开发两种方法，支持产品开发人员在多标准的质量减少和质量再分配。这两种方法应该结合成一种方法，同时考虑到基础研究。这最终将在与工业伙伴合作进行的若干案例研究中得到验证。
