Parametric design is essentially a generative design that can be created using a computer and mathematical relationships. In a process-oriented way (instead of changing the shape), we modify the components' parameters that make up the shape, resulting in a new look. Because manipulations' consequences can be seen immediately, the development of product families and new product variants can be implemented quickly. With the help of parametric design, customizing the product and increasing customer satisfaction is more efficient, as several successful projects have already shown in automotive industry, aircraft manufacturing, architecture, jewellery manufacturing, etc.

Nowadays product designers have possibilities to design complex geometries, since for instance with additive manufacturing, there is less technological limits then before. However, besides that they have geometric freedom, it is essential to pay attention to engineering aspects, such as efficient material usage, stiffness and so on. This article is dealing with internal support structures and introduces a new lattice, called Lightweight Voronoi Scaffold. The scaffolds as 3-dimensional structures are well known in numerous fields of science. These structures provide mechanical stiffness for bones and place for biomolecules as well. The aim of this research was testing this new structure in case of complex geometry with multiaxial load case. Therefore, the arrangement of Voronoi scaffold is not regular, random sampling-based Monte Carlo method was applied in order to provide proper distribution of generation of geometric instances. Although the random point seed generates a high number of improper geometries, the remaining ones always include notable solutions. Lightweight Voronoi Scaffold was compared to some common regular beam lattices, and results shown that Lightweight Voronoi Scaffold was lighter in each case, that may open new opportunities in the field of additive manufacturing.

Aging societies have an extended need for transportation solutions that enhance elderly's independence. However, the solutions needed are as manifold as the elderly's lifestyles are. This study uses Usercentred Design principles as a structuring tool to manage this complexity of requirements. By not just focusing on specific functionalities but also reflecting product life cycle and usage context, new types of requirements can be revealed. Through a case study, this article shows how a participatory design approach can lead to integrated solutions that better fit the user's needs.

Nowadays, the aesthetic appearance of a product becomes more and more important in several industries. Psychologic studies and researches highlighted that beside the functionality of a product, aesthetic appearance is one of the key factors of the decision-making process before buying a product. The geometric properties—such as basic geometries and lines—of patterns that are simple structures, usually consist of replication of simple elements or their mathematically described modifications. These are all in connection with human emotions. A software called EmPatGen (Emotional Pattern Generator) has been developed that creates patterns automatically based on user preferences. The focus of this research is to support the work of product designers in the automotive industry. With the aid of this program, they are able to design the most aesthetically pleasing car interiors and fulfill specific customer requirements in a much easier manner. This study focuses on the connections of basic geometries and lines created with the introduction of a novel pattern generator program and mathematical model which is based on fuzzy logic.
