Innovation Design of Pneumatic Pump Reversing Mechanism Aided by Patent Knowledge

Based on the theory and method of innovative design aided by patent knowledge, this paper analyzes the existing patents about pneumatic pump reversing devices and the other patents, and establishes the library of principles and structures which can achieve reversing function. As there are many shortcomings of existing pneumatic pump reversing devices such as a lot of collisions, big noise and difficult to manufacture, based on the principles and structures which can achieve reversing function, this paper proposes two new pneumatic pump reversing devices to help solve these problems. Compared with the existing pneumatic pumps, the new devices have many advantages, such as simpler structure, less collision, less noise and less cost.
