The document discusses examples of both good and bad design through several case studies:
1. The IKEA gate leg table is praised for its space efficiency, ability to serve multiple purposes, and built-in storage - making it a good design for small spaces.
2. A classroom's overhead projector setup is criticized for poor placement that blocks students' views and causes glare, showing bad design.
3. A makeshift wired network solution is acknowledged to sacrifice design for functionality in circumstances where WiFi is unavailable.
