Background: One unfortunate consequence of the invention of the car is that cities started being designed for car-only use. In most cities built in the last ~70 years, the concept of a high-density walkable residential-and-commercial space only exists in shopping malls and amusement parks (Figure 1). The Issue: The main issue here is that cars…

Background: Vertical blinds (https://www.google.com/search?q=vertical+blinds) are a popular method of providing privacy for a large window or sliding door. These blinds are usually controlled by two different looped cords: The Issue: Unfortunately, since these cords are both loops, they really appears as TWO cords. The user must somehow know which of these unlabeled-and-often-twisted cords is the…

Background: In some climbing gyms, there are introductory climbing walls for children where the climbable hand holds are shaped like a recognizable object (Figure 1), instead of a random-looking piece of stone. Using the 26-letter (capital letters only) English alphabet, we can assemble a reasonably sized climbing wall wall without using any duplicate letters. The…

Background: In the United States, the phrases “castle doctrine” and “home defense” most often refer to the idea of using guns to defend oneself from potential home invaders (specifically, by shooting them). However, despite the castle-related terminology, what is strangely lacking is any actual home defense (in the sense of medieval fortifications). See Figure 1…

Background: In the years before the invention of the car, the only way to design a city was with walking (or at least public transit) in mind. However, once cars became widespread, cities started being designed with wide roads and large areas set aside for parking. The Issue: This style of design made driving very…

Background: A previous idea (July 19, 2021: worstplans.com/2021/07/19/) was to make stairs safer by specially marking the top and bottom stairs. But why not expand this idea to the entire staircase! The Issue: Surprisingly, falling down stairs is a major source of injury. People are particularly prone to falling down stairs when they’re distracted in…

Background: A “snail” is a slug-like creature with a shell on its back. Many snails can entirely retreat into their shells for protection, which lead people to describe the snail as “wearing its house on its back.” (This is not strictly accurate, since snails do not pay property tax.) The Issue: High cost of living…

Background: Many cities have restrictive zoning requirements that, perhaps justifiably, prevent certain types of construction (for example, building a pesticide manufacturing plant next to an elementary school). Some restrictions are a bit more arbitrary: many “homeowners associations” (HOAs) enforce extremely specific details about the exact shades of beige that a garage door can be painted,…

The issue: The presence of windows in a house is a major factor in determining of whether a house is dark and cavern-like or bright and uplifting. Unfortunately, it is usually impractical or impossible to add windows to a home after its has been constructed. Additionally, windows generally have a negative effect on climate control:…

Background: A cat owner may install a “cat door”—a cat-sized flap—in a door in their house (Fig 1). This allows a cat to travel freely even when the human-sized door is closed. A cat door also removes the need for the cat to carry a set of keys. Proposal: But why should cats get all…
