Ecological and Societal Transition Challenge

Context and Stakes

At the beginning of the first year of the engineering cycle, as part of a project aimed at raising awareness of current climate issues, we were led to reflect on our role as engineers in facing the challenges of ecological transition. The project was carried out in a team of seven students from diverse fields:

• 2 in Mechanical Engineering
• 2 in Civil Engineering
• 1 in Biological and Food Engineering
• 1 in Embedded Systems
• 1 in Computer Science and Statistics

The project’s goal was to rethink our lifestyles, particularly regarding mobility. We proposed a solution to make heavy trucks more ecological by equipping their cabins with pantographs to capture electricity via overhead catenaries installed above highways. This approach would enable 100% electric propulsion without relying on bulky batteries, optimizing the space at the back of the cabin to integrate the system.

Objectives

• Imagine an innovative solution aiming to significantly reduce pollutant emissions from heavy trucks by rethinking their power supply.
• Design a functional prototype illustrating the chosen technical principle, particularly the energy capture system via highway catenaries.
• Develop a comprehensive dossier including technical plans, a feasibility study, deployment cost estimates, and a medium- and long-term environmental assessment.

My Role

• Responsible for designing the functional prototype, collaborating with a peer specialized in Civil Engineering.
• Designed and fabricated a wooden scale model using laser cutting to minimize costs and facilitate rapid assembly.
• Reused components from recovered materials to strengthen the project's sustainability and illustrate the system's overall operation.

Methodology

1. Team brainstorming phase to identify an innovative solution related to transportation and reducing its environmental impact.
2. Initial evaluation of the project’s environmental and technical feasibility, including a preliminary life cycle assessment.
3. Design and manufacture of a physical scale model from available and recycled materials, aiming at cost minimization.

Technologies & Tools

Machines used: laser cutter for model fabrication, electrical measurement instruments for testing the electric motor’s operation.
Materials: wood, recovered components (small mechanical parts, mounting supports).
Digital tools: presentation software (PowerPoint/Canva) for the report, spreadsheets for simplified environmental analysis.

Lessons Learned

This project helped me deepen my project management skills and offered a concrete first approach to issues related to eco-design and energy transition in transportation.
I learned to collaborate within a multidisciplinary team, to confront and reconcile different technical viewpoints, and to adapt to material and time constraints.
The project also raised my awareness of the importance of communication in showcasing a technical solution to a non-specialist audience, particularly through the creation of a representative physical model.

English Project

Context and Stakes

During my final year of integrated preparatory studies, we had the opportunity to carry out a language project in a team of three. We had the freedom to choose the topic as well as the medium. We therefore created a board game themed around Formula 1, inspired by Trivial Pursuit. We wrote the game rules, developed the questions and answers, as well as the game mechanics. Finally, we designed and physically manufactured the game, which is fully playable.

Objectives

• Create an original and freely designed board game
• Improve English skills through a playful project
• Design a game that is both fun and fully playable

Electric Knife Project

Electric knife to analyze

Context and Stakes

The "electric knife" project, carried out during my second year of integrated preparatory studies, aimed to model and analyze the mechanical operation of a domestic electric knife.

Done in pairs, this project focused on the kinematic analysis of the linked parts, enabling us to understand and reproduce the cutting motion. This modeling allowed us to identify key components, study their mechanical interactions, and deduce the motion laws governing the system.

Objectives

• Model the main parts of the electric knife using Creo Parametric software
• Analyze the kinematic operation of the mechanism by identifying movements transmitted between parts
• Understand how the motor's rotational motion is transformed into the blades' reciprocating movement
• Illustrate overall operation through a 3D assembly and motion animations

My Role

• We jointly conducted the overall kinematic analysis to understand the movements generated by the mechanical links.
• I then took charge of the complete 3D modeling of parts and the mechanism animation under Creo Parametric, to visually illustrate the knife's operation.

This project enabled me to develop my skills in kinematic analysis of a real mechanical system.

I strengthened my mastery of Creo Parametric, especially in precise 3D modeling based on real measurements, and in creating animations to illustrate mechanism functioning.

Working in a pair also taught me how to collaborate effectively on modeling tasks, distribute work evenly, and communicate rigorously about technical constraints encountered.

Checkerboard Robot Project

Context and Stakes

As part of this project carried out in pairs of four students, our goal was to fully design an autonomous robot. The robot had to move on a chessboard from a defined starting position, navigate to a specific (pre-known) position to pick up a boat, then return to its initial position while avoiding a statuette placed on its path.
