Power-Optimized Design Framework for Automatic Beverage Dispensing Machine

Present day embedded devices continue to evolve in both hardware and software realms to be more efficient. Power consumption is one of the crucial factors that need to be taken into consideration during the design and development of such products, especially when targeting consumer markets and used as portable devices. This paper presents a novel design and implementation of a low-power, cost-effective automatic beverage (cocktail) dispensing machine. The low power consumption of this device is attributed to the selection of components that consume low power and due to the use of relays that ensure the pumps are “ON” only when they are required. Compared to similar existing products in the market, our design has resulted in 59% of savings in power consumption. The device can be operated using a 12V battery with the same performance level in usage.
