01 / Leadership
Creating the structure
for others to build.
Yiming Aizezi co-founded and led Engineering Society with Junze Wang and Thomas Refalo. His contribution extended beyond running activities: he helped shape technical content, prepared physical and visual teaching materials, communicated engineering principles and supported students as they moved from concepts to prototypes.
The leadership team documented weekly sessions and project outcomes, creating a record that could support continuity, reflection and future teaching.

Leadership in practice
Direction made visible.
Technical communication
Explaining motion, force and transmission through concise lessons, diagrams and demonstrations.
Resource creation
Producing slides, printed mechanisms and reusable materials for hands-on learning.
Team mentoring
Helping students make design decisions, test ideas and retain ownership of their work.
Documentation
Recording sessions, methods and outcomes so the programme could develop over time.

Mechanical Engineering Prototype
Swiss Escapement Mechanism
Yiming introduced the Swiss escapement mechanism, a key mechanism commonly found in mechanical watches. He analysed the motion, designed the components and manufactured them using 3D printing.
Students were challenged to assemble the mechanism as a coordinated process, inspired by Henry Ford’s early moving assembly line concept.

Engineering Education Workshop
Mechanical Mechanisms Workshop
For the 5 February 2025 session, Yiming created educational materials covering levers, gears, cam and followers, and linkages. When the chairs could not attend because of a school commitment, he recorded and edited the complete lesson so the class could continue.
- Transfer motion between components
- Change the direction of motion
- Create mechanical advantage
- Convert rotational motion into linear motion

Mechanical Transmission
Toroidal Launcher
Yiming 3D printed the demonstrator used in the 12 February session. Two planetary gear stages produce a 1:48 transmission ratio before the rotating toroidal element is launched.

Educational Engineering Design
Custom Mechanical Demonstrators
Yiming designed and manufactured mechanisms that made motion relationships tangible. One example converted continuous rotary motion into intermittent rotary motion with discrete pauses.

Engineering Competition
Egg Drop Challenge
The society introduced the challenge on 19 February 2025 and supported it through April. Around 25 participants formed roughly seven teams to design, prototype and refine protective structures.
Yiming designed and 3D printed 0.4 mm-wall PLA eggs with durability similar to real eggs, reducing mess while making early tests safer and more repeatable. The teaching connected potential and kinetic energy, momentum, impulse, crumple zones and force duration to design decisions.
