Increasing the performance of a Salt Washing Machine through Axiomatic Design
| Resumo: | Systems with fewer design parameters (DPs) than functional requirements (FRs) are coupled or cannot achieve all their FRs simultaneously, as per Axiomatic Design's theorem 1. In that case, production processes have lower productivity and production rate than uncoupled or decoupled designs. This paper reports the upgrading of a salt washing machine concerning its performance, not only on separation of salt from saltwater but also on washed salt production. The machine analysis showed it is a coupled design, with one more functional requirement than the design parameters. A viable enhancement was the addition of one design parameter, which made it possible to control separation and washing independently. This redesign enforced functional independence and allowed increasing the production rate between 20% and 30%. Furthermore, one could perceive increased productivity, quality of the final product, and reduced water and energy consumption. |
