Introduction
Friction hinges are commonly used in various applications such as laptops, tablets, and automotive interiors. They provide smooth and controlled movement while maintaining the desired position. In this article, we will discuss the history and development of friction hinges.
Early Development
1. The first friction hinge was invented in the 1930s by the Swedish engineer, Arvid Palmgren.
2. It was used in the design of a folding camera and was made of a simple metal strip with a friction pad.
3. During the 1950s and 1960s, friction hinges were used in the aerospace industry to control the movement of aircraft parts.
4. In the 1970s, friction hinges were used in the design of laptop computers to control the opening and closing of the screen.
5. These early friction hinges were made of metal and relied on the friction between two surfaces to provide resistance.
Modern Development
1. In recent years, there has been a shift towards using plastic materials in the design of friction hinges.
2. This has resulted in a more lightweight and cost-effective solution.
3. Additionally, the use of plastic materials has allowed for more complex designs and shapes.
4. Friction hinges are now commonly used in automotive interiors to control the movement of consoles and seats.
5. They are also used in medical equipment to control the movement of monitors and screens.
6. The development of new materials and technologies has allowed for the creation of friction hinges with increased durability and precision.
7. The future of friction hinges looks promising with continued advancements in materials science and engineering.
