DFX 2022 33rd SYMPOSIUM DESIGN FOR X
The 33rd DfX Symposium will take place on 22nd & 23rd September 2022 in Hamburg.. DFX 2022 offers young scientists a platform for presenting new ideas and approaches for improving product development.
Knowledge Base Repository
In addition to research papers, the Design Society is developing several valuable resources for those interested in the study of design. These include a repository of PhD theses, a library of case studies and transcripts of design activities, and an archive of our newsletters. Please note that these resources are accessible exclusively to Design Society members.

Abstract:
When developing products, engineers face challenges in solving technical, economical, but also ecological conflicts of objectives. A common technical conflict is the contradictory behaviour between the stiffness and mass of components. A possibility to resolve this contradiction is offered by multimaterial components, which are made possible by a loadoptimised design. Taking the example of topology-optimised multi-material components, this article shows a method for taking the ecological impact of raw material extraction into account in selecting suitable designs by offsetting a performance index with the results of ecological impact assessment calculations. These results are analysed in order to identify a possible solution according to the technical-ecological conflict of objectives.
