Design for Assembly - Redesigning AC Control Valve

Engineering

Task 1 Design for Assembly
In this project, we have to redesign the given AC control valve. The given design
contains 12 components on it. Among them frame, valve plate and control stick are the major
components. These three components are essential for the functioning of the valve. Without
these three components not possible to achieve the functioning of the valve. So the minimum
number of parts is “three” for the given design.
Justifications
 The given component has two main functions. One is “Control the flow rate of the gas”
and another one is “Act as an extension pipe”.
 Frame, control valve plate and control stick is enough to do that.
 Here the other components like bush, rings and sheet metal cases are used to improve the
performance of the valve. But these are not the major functional parts.
 So the major functional parts of the design are three.
