Bellows is a mechanical device designed to compress and expand in order to produce a strong directional airflow, consisting of a flexible chamber that can be squeezed to expel air through a nozzle or expanded to draw air in. This fundamental mechanical innovation, dating back to ancient civilizations, has played a pivotal role in various design applications, from metallurgy and industrial processes to musical instruments and photography. In its most basic design form, bellows typically incorporate pleated or accordion-like walls made from leather, cloth, or synthetic materials, supported by rigid end plates that maintain structural integrity during operation. The engineering principles behind bellows design emphasize the importance of airtight construction, durability of materials, and optimal compression ratios to maximize airflow efficiency. Throughout history, bellows have evolved from simple hand-operated devices to sophisticated mechanical systems, incorporating various design improvements such as double-action mechanisms, automated control systems, and specialized nozzle configurations. In industrial design applications, bellows serve critical functions in metalworking, glassblowing, and forge operations, where precise control of airflow is essential for maintaining specific temperatures and combustion conditions. The design considerations for modern bellows extend beyond mere functionality to include ergonomic factors, material sustainability, and integration with contemporary manufacturing processes. These devices continue to be recognized in design competitions, including the A' Design Award's industrial design category, particularly when innovative approaches to their construction or application are demonstrated. The versatility of bellows design has led to their incorporation in diverse fields, from precision scientific instruments to architectural elements, showcasing their enduring relevance in both traditional crafts and cutting-edge technologies.

The word bellows is believed to have a Germanic origin, derived from Proto-Germanic *blǭgō, meaning 'to blow', probably in reference to its use for blowing air into a fire. In Old English, the word was beolu and later blǭgō in Middle German, all of these meaning 'bellows'. This is evidenced in the early 13th century, when the word appears in Anglo-Norman as buelue and Middle English as belwe. Morphologically, the word bellows consists of the root word bell, which is thought to have the same origin as the Proto-Germanic *blǭgō, and the suffix -ows, which is of North Germanic origin. In terms of pragmatics, bellows is used to describe a device for producing a strong current of air, generally with a handle and a mouthpiece, used to blow air into a fire or some other kind of furnace.

Bellows are a collapsible extension of cloth, leather, or other material used to extend the range of a camera’s lens. They are commonly used in macro photography, allowing photographers to take sharp close ups of small objects. Bellows are also used in landscape photography, allowing photographers to take far distance shots with quality and clarity. Notable photographers who have used bellows in their work include Alfred Stieglitz, Edward Weston, and Ansel Adams.
