Background: When you receive a message on a phone, usually the phone vibrates or makes an alert sound. The issue: If someone sends several short messages in a row (e.g. “Here is the restaurant:” “(link to restaurant address)” “We’ll be there at 7 pm.”) or if a conversation has several participants, your phone will be…

The issue: Dental floss has a serious problem with unnecessary waste: each length of dental floss has a “dead zone” at the ends that is used to wrap around fingers. This unused region is thrown away without ever having been actually used as dental floss (Figure 1). Proposal: Instead of wrapping the dental floss around…
-
Background: It’s difficult to move heavy furniture around, so furniture is usually positioned for general use, even if there are specific setups that would be better for rare situations. For example, your home might have a room that would be best configured in one way for watching movies, but a different way for a Thanksgiving…

Background: People generally enjoy having a good view from their home or office windows. However, some locations have a bad view (e.g. a dark alley or cement wall) or cannot accommodate windows at all (e.g. interior offices or basements). Proposal: Modern flatscreen displays can be as large as office windows (and some types consume very…
-
Background: “Lost cat” and “lost dog” signs are often placed up on telephone poles (Fig. 1), but it’s unlikely that a specific person who sees a lost pet will also have seen the sign (or even know that the pet is actually lost in the first place). Proposal: In order to add more people…

Background: Many companies issue ID badges to their employees. Sometimes these come in multiple forms: one type of badge for permanent workers, and a different color for temporary employees. Proposal: In order make the time-limited nature of temporary employees more clear—and perhaps to remind the temporary employee to start applying for jobs again—a low-power timer…

Background: Once you know how to read, it’s impossible to see text the same way as you did before—you will inescapably recognize the symbols as letters the instant that you see them. The issue: This “automatic” parsing of written language makes it easy to forget how much effort was required to initially learn how to…
-
Background: Rail-based transportation has an inescapable problem: in a single-track situation, there is no way for a train to pull over and let another train pass. The issue: Thus, a single stopped train can block an entire track indefinitely. And a slow train can’t be overtaken by an express train. This can be solved by…

Background: When baking a pizza in an oven, it’s it’s easy to remove the pizza from the oven and instantly start devouring it. The issue: Unfortunately, molten cheese (Fig. 1) cannot coexist with human tissue, so this causes severe burns to the impatient pizza-eater. Proposal: We can prevent further occurrences of this culinary tragedy by…
-
Background: When giving a presentation to a diverse audience (e.g. of experts and non-experts, or of employees from two different departments in a company), you have a problem: you can only make one set of slides, but sometimes you might want to tailor different parts of the presentation to a different audience. For example, one…
