Sharps Disposal
A mini project. Design a container for used blades that lets them in and never lets them out — then draw it to scale using your new multiview and isometric skills. You don't build this one. The drawing is the product.
The problem
Used utility and craft blades end up in the classroom trash. Someone gets cut — a student emptying a bin, or a custodian lifting the bag. The client wants one cheap plastic container that holds used blades safely all year and then goes in the trash with the blades still locked inside.
Takes four blade sizes. Blades stay in even if it's knocked over or turned upside down.
A single plastic part. No lids, flaps, or moving pieces.
The phases
This project covers the first three phases of the design process. It stops before building.
- Define the problem. What's the real issue, what does "done" look like, and what limits you?
- Research and brainstorm. At least three different concepts, sketched in your notebook.
- Pick a solution and draw it. A scale multiview drawing and an isometric drawing of your best idea.
Then you present it.
What you hand in
- Notebook pages. Notes on material choices, manufacturing, and any other research. See what to research.
- Brainstorm sketches. At least three different concepts. They must answer the design questions.
- Technical drawing. Front, top, and right side views with hidden lines, plus an isometric view. To scale, with dimensions. One multiview/isometric sheet is enough. See how to draw it.
- Presentation. 2–4 minutes to the class, using your drawings and sketches as visuals.
This is an individual project. Everyone hands in their own work and gets their own score.

Research and 3+ sketches
Multiview and isometric
2–4 minutes each
Never handle a used blade to check a measurement. Work from the samples shown in class.
