Evaluation of Fluid Dispensing Systems Using Axiomatic Design Principles

Fluid dispensing systems have been widely employed in industry, by which fluid materials are delivered in a controllable manner. Currently, various designs of fluid dispensing systems exist; however, there is a lack of evaluating and comparing these different designs on a common base. This paper presents such an evaluation by means of axiomatic design principles. In particular, existing designs of dispensing systems are illustrated as decoupled and redundant ones based on the models available in the literature; and the information content of each design is calculated by using the algorithm specially developed in this paper for redundant designs. The results from such an evaluation will not only allow users to choose the appropriate systems for given applications, but will also facilitate designers to develop new dispensing systems.
