Introduce 'talking' or 'quiet' seats on airplanes, which would be offered in addition to the routine window or aisle options. Then, they can seat passengers according to their chatting preference. Extroverts will be assured that the person next to them wants to make small talk as well, and introverts can be guaranteed a quiet ride.

Introduce bench meters to public parks. These secure coin operated devices would work like parking meters. The new income stream generated would pay for the maintenance and cleaning of existing benches and the purchase of additional benches. Off-peak times (i.e. dusk to dawn) would ensure that homeless individuals electing to sleep on these benches at night could do so without the risk of incurring a financial penalty.

This horn would have a happier, more comic tone and be accordingly visually represented on the dashboard. A few road rage incidents may be avoided if drivers could differentiate more clearly between annoyance and gratefulness. A range of...

Invent a holder for bathroom products, such as shampoo, shower gel and conditioner that would gently warm them up, thereby avoiding these chilly blobs of cleansing fluids interrupting a nice warm shower.
