What are the design features that prevent the trash can from being used as a step or seat?

Trash cans in public spaces are often subjected to unintended uses, such as being stepped on or sat upon. To address this, designers incorporate specific features to deter such misuse while maintaining functionality.

1. Sloped or Rounded Surfaces: Many modern trash cans feature sloped or rounded tops, making them unstable for sitting or standing. The lack of a flat surface discourages people from using them as makeshift steps or seats.

2. Lightweight or Unstable Materials: Some designs use materials that bend or shift under weight, preventing the trash can from supporting a person’s weight. This ensures they remain solely for waste disposal.

3. Sharp Edges or Protrusions: Certain models include subtle sharp edges or uncomfortable protrusions, making them unpleasant to sit on without compromising safety for regular use.

4. Height and Shape Optimization: Trash cans are often designed to be either too tall or too short for comfortable seating, and their shapes may lack support for prolonged use.

5. Durability-Focused Construction: Reinforced structures prevent damage from accidental misuse, ensuring longevity while subtly discouraging improper use.

These design choices prioritize public safety, durability, and the intended purpose of trash cans, keeping urban spaces clean and functional.
