We use advanced tools that support the entire design process – from mechanical design (Siemens NX, CATIA, SolidWorks), 3Dexperience platform, electrical design (EPLAN Electric) as well as simulations and analyses (Abaqus, ANSYS). We select software in accordance to specifics of each project. Our experts also have experience with other tools, which allows us to be flexible and adapt to the client’s requirements.
Yes. We use AI-assisted tools to support engineering analyses, compare design alternatives, and identify potential issues at early stages of development. This helps teams evaluate different scenarios more efficiently, reducing the need for late design changes and additional testing. AI supports the decision-making process, while the final assessment, interpretation of results, and selection of solutions always remain the responsibility of experienced engineers.
es. AI can support concept evaluation and the generation of design alternatives, helping teams move more quickly from ideation to prototyping and validation. Combined with simulation tools and rapid prototyping technologies such as 3D printing, it can help reduce the number of design iterations required to achieve the desired outcome. However, every prototype is reviewed, validated, and approved by engineers who are responsible for its functionality, safety, and compliance with project requirements.
Yes. AI-assisted tools help streamline selected tasks related to technical documentation, data analysis, and engineering development activities. This allows engineers to focus more on work that requires expertise, experience, and technical judgment. AI serves as a support tool, while all documentation, design decisions, and engineering deliverables are reviewed and approved by qualified specialists.
We expect the use of AI to continue expanding in areas such as product design, simulation, documentation management, and product data analysis. Its greatest value lies in accelerating routine engineering activities and reducing repetitive tasks, enabling teams to work more efficiently. However, we do not see AI as a replacement for engineers. On the contrary, as these tools become more widely adopted, the role of engineering experts in interpreting results, making design decisions, assessing risks, and ensuring compliance with customer and industry requirements will become even more important.
Our engineering teams follow Design for Manufacturing (DFM) and Design for Assembly (DFA) principles from the earliest stages of development. By considering manufacturing and assembly requirements from the outset, products are more likely to reach a production-ready design with fewer modifications and design iterations. This approach helps reduce development costs, shorten time-to-market, and improve overall product quality.
