Module 6 : Bending & Flexing 
  Lecture 16 : Hinges, Flexstraw, Bellow
 

Bellow Paradigm

The principle of bellow paradigm is similar to Flexstraw Paradigm. The air-bridge at the airport works on the same principle of bellow paradigm. The bellows is the flexible element with expansion joint. This element is designed to absorb thermal, to absorb mechanical movements. The bellows is a very unique component having piping passage system that provides strong to accommodate the system design pressure, as well as, flexible enough to accept the design deflections.

Bellow function like Bending Paradigm that allows flexibility and protects from various forces that may act upon the product.. It has inspired designers to create large number of product application that are use for utilizing the flexibility of a passage joints between two members. Traditional camera (plate 17 A&B) used bellow connect between the lens and the body. To blow air with the help of bellow (plate 17C) to the fire place was common practice.
