From June 25 to 27, the 27th International Conference on Human-Computer Interaction (HCII) took place in Gothenburg, Sweden. KTmfk contributed with a scientific paper at the affiliated 16th International Conference on Digital Human Modeling & Applications in Health, Safety, Ergonomics & Risk...

The development of complex products is characterized by ever-increasing requirement specifications. Use cases are often used to take these into account in a structured way during product development. Since their manual identification is very time-consuming, especially in large requirements specifica...

When generating an optimal design proposal, one of the main challenges is to maximize material efficiency and minimize stress concentrations while taking various boundary conditions and loads into account. In this context computer-aided algorithms are increasingly being used in terms of structural o...

On June 3 and 4, 2025, the 16th VDI Conference " Gleit- und Wälzlagerungen: Gestaltung – Berechnung – Einsatz" took place. The Chair of Engineering Design (KTmfk) actively participated in the conference with two contributions. In addition to Prof. Sandro Wartzack and Felix Pfister, students Max Poh...

The European Group of Research in Tolerancing (E-GRT) met for the 6th time - this time in Milan, Italy. The E-GRT is an association of chairs from France, Sweden, Italy, and Germany with the aim of promoting and strengthening international cooperation in the research field of tolerancing. The event ...

At KTmfk, we often faced this challenge — especially when trying to reuse and communicate tolerancing approaches across disciplines in research and industry projects. After three years of collaboration, we are happy to share the results in our latest publication. We introduce a holistic descripti...

The KTmfk took part in SheMet25 in Paderborn from March 31 to April 3. SheMet is an international scientific conference that focuses on current developments, methods and applications in sheet metal processing and forming technology. The KTmfk was represented by a scientific paper by Jonathan-Markus ...

From 2nd to 4th April 2025, the 35th CIRP DESIGN CONFERENCE took place at the University of Patras in Greece. KTmfk contributed with two scientific papers and was represented by Jessica Pickel, Marc Behringer and Prof. Sandro Wartzack. The presented topics included an overview on the use of ontologi...

Preliminary design decisions shape a product’s entire lifecycle, yet freehand sketching remains disconnected from digital workflows. Our study explores natural VR modeling as a viable alternative, enabling intuitive, CAD-compatible 3D modeling. A controlled user study compared VR modeling and sketch...

Developing user-centered products requires a careful balance between usability and emotional design. While usability ensures efficiency and intuitive handling, emotional design shapes user perception and acceptance. But what factors influence this interaction? A recent systematic literature review i...
