This design feature is commonly found in furniture, such as 접이식 테이블 (folding tables) and 접이식 의자 (folding chairs), allowing them to be conveniently stored when not in use. The concept of "접이식" is also applied in various products, including 접이식 자전거 (folding bicycles) and 접이식 스마트폰 (foldable smartphones).
