Chindogu are unusual inventions that combine everyday objects in surprising yet "unuseless" ways. Some examples provided include a lawn chair with an attached garden hose for cooling off, a bike with a velcro-attached coffee mug holder, and a rocking chair combined with an exercise bike to make working out more enjoyable. The document also lists additional chindogu ideas such as a ceiling fan fitted with clothes pins to dry laundry and patio furniture with a foot-activated trash bin lid for easy cleanup.
