Design Project: The Great Leaf Collector

Each fall, millions of leaves drop to the ground — and someone has to clean them up! 

Your student's challenge is to design a Leaf Collector that helps make leaf cleanup faster, cleaner, and more fun.  

The device could be:  A manual tool (like a rake-inspired collector with a unique twist)  A mechanical device that uses gears or rolling elements  A small robot concept that collects and stores leaves  Or even a fun, nature-friendly gadget that makes leaf cleanup a game!  Creativity counts — think of imaginative or humorous ideas like a “leaf vacuum dragon” or “rolling leaf monster.”

• Must be modeled using CAD software (e.g., SolidWorks, Onshape, Fusion 360).
• Must include at least 3–5 parts assembled together.
• No motors, chemicals, or sharp/pressurized components — safety first!
• Functionality should be based on simple mechanisms (e.g., gears, scoops, cranks, rollers).
• Must be ergonomic and environmentally friendly.

• Research:
  Study how leaves are currently collected (rakes, blowers, vacuums). Identify their pros/cons.
• Brainstorm:
  Sketch multiple ideas for collecting leaves safely and creatively.
• Design in CAD:
  Model your parts, ensuring all components fit together.
• Test Virtually:
  Use assembly motion studies or animations to simulate your design.
• Present:
  Create a short presentation or poster describing:
  • The problem your design solves
  • Your CAD model and parts
  • How your design works
  • Why it’s unique or fun

Goal:
Create a simple, hand-powered leaf collection tool that can scoop or gather leaves.

Beginner Requirements:

• 3D model with at least 3 unique parts (handle, scoop, connector, etc.)
• Include 1 moving component (e.g., hinge, rotating arm).
• Must include a creative or fun design element (color, theme, or mascot).
• Generate a technical drawing of one main part with dimensions.

Examples:

• Dual-handed “Leaf Scoop Claws”
• Foldable “Pocket Rake”
• “Leaf Tong” grabbers

Goal:
Create an advanced concept that could automate, store, or transport leaves — all virtually using CAD/CAM tools.

Advanced Requirements:

• Full assembly of 6–10 parts with at least 2 moving mechanisms.
• Demonstrate how leaves would be collected, stored, or dumped (animation optional).
• Apply CAM principles by exporting one part to a toolpath simulation or 3D print preview.
• Include an exploded view and Bill of Materials (BOM).

Examples:

• Mini push-cart leaf collector with rolling brushes
• “Leaf Bot” that uses a conveyor scoop
• Bike attachment for collecting leaves along the path
• “Eco-Vac” with a leaf-mulching compartment
