Divisus
This is the bachelor's project I completed in May 2025 together with my study group. We were a team of four students who collaborated closely throughout the entire design and development process. The result is a product concept that combines functionality, aesthetics, and user-centered thinking.
On this page, I present selected parts of the project, highlighting the areas where I either took the lead or contributed significantly. While the project was a group effort, I want to showcase the specific responsibilities I had—whether it was managing the 3D modeling, performing FEM calculations, developing technical drawings, or leading the prototyping process.
Each image or section is accompanied by a short description that explains what the task involved and how I approached it—either independently or in collaboration with the rest of the team.
3D file
The 3D model shown here represents the final design proposal developed by our group during our bachelor's project. I acted as the lead on 3D modeling, and was therefore responsible for creating nearly all CAD files used in the project.
The modeling was done in Fusion 360, as it was the software most familiar to the team. However, I am also fully capable of working in SolidWorks when needed. The product was modeled as individual components, each built with proper constraints, and later assembled within the software’s assembly environment to test fit, tolerances, and spatial relationships.
Where possible, I also imported standard components (e.g., pneumatic cylinders, screws, and switches) from manufacturers’ databases to ensure realistic dimensions and integration — a practice aligned with standard industry workflows.
Although I didn’t produce the final renderings included in the project report, I was instead responsible for developing the technical drawings that documented the design in full detail for production and prototyping.
This part of the process demonstrates my ability to manage and deliver a complete and organized CAD pipeline, from part modeling and assembly to production-ready documentation. I work with structure and accuracy, and I always aim to build models that are both editable and aligned with real-world manufacturing methods.
Technical drawings
After completing the 3D CAD files for our final concept, I took primary responsibility for creating the technical drawings for the product DIVISUS. While all drawings were reviewed and validated in collaboration with the rest of the team, I produced the majority of the drawing set, including detailed component drawings, exploded views, and section drawings essential for understanding internal construction and assembly.
My focus was on creating clear, standardized, and production-ready documentation. The drawings adhere to ISO 2768-1 – F tolerances, and although the tolerances may in retrospect be slightly finer than necessary for certain components, they reflect a deliberate attempt to ensure precision and clarity.
The drawing package includes detailed dimensions, material specifications, surface treatments, and fits for all major components, from CNC-machined parts in stainless steel to molded polyurethane elements. In particular, I ensured critical internal spaces—such as channels for electronics and pneumatic tubes—were properly dimensioned and communicated in sectional views.
Looking back, one of the last drawings, the rear panel (Bagpanel), presented a challenge due to its complexity. In hindsight, it would have been more production-friendly to split this part into multiple pieces. However, the drawing still reflects my ability to communicate complex geometry within a tight timeframe.
This process deepened my understanding of design for manufacturing (DFM) and reinforced my ability to translate digital models into precise, industry-relevant documentation. I’m confident in preparing drawing packages that can move directly into prototyping or production, including attention to material selection, tolerancing, and clear communication with manufacturers.
FEM analysis
In the DIVISUS project, I was responsible for evaluating the mechanical strength of the product’s load-bearing components. I combined manual calculations with Finite Element Method (FEM) analysis to ensure that the structure could withstand the expected forces in use.
The process began with dimensioning the beams and support rods to handle the load generated by the pneumatic cylinder, while meeting a group-defined deflection limit of less than 1 mm at the free end. Using classical engineering formulas—including bending moments, stresses, moments of inertia, and deflection—I calculated the critical cross-sections and selected suitable dimensions. Particular attention was given to analyzing both strong and weak axes, and to how the orientation of the rods would affect the neutral axis and load distribution.
These manual results were then validated using FEM simulations in SolidWorks, where I compared the theoretical values with digital simulations of stress distribution and deflection. The results aligned closely, providing a solid foundation for confidence in the mechanical performance of the design.
These calculations directly informed key decisions in the development of both the functional prototype and the final model. They were essential for selecting the appropriate cylinder size, rod thickness, and material strength, ensuring reliable function without over-engineering.
This process highlights my ability to work across both theoretical and digital tools, and to use data-driven insights to support critical design decisions. I approach technical challenges analytically and systematically, with a strong understanding of when to rely on physical prototyping and when validated calculations are sufficient.
