Problem Statement and Value Proposition
Problem Statement: The problem we are exploring addresses companies that use surface mount device (SMD) feeders as part of their printed circuit board (PCB) manufacturing process. When these companies use an SMD feeder to dispense components, they can easily lose track of the amount of components that are remaining on the reel. This causes inaccuracies in inventory, which can lead to productivity losses and increased costs due to manufacturing errors and downtime.
Value Proposition: Our Smart SMD Feeder helps PCB manufacturing companies keep track of component inventory by counting components and updating the database automatically. This enables employees to spend less time counting and locating components, and more time completing products, which improves profitability.
Proposed Solution
Marketing and Engineering Requirements
Marketing Requirements
MR1-Smart Feeder accurately keeps track of component count on SMD reels
MR2-SMD component database is automatically updated by Smart Feeder
MR3-Smart Feeder fits inside the pick and place machine used for creating PCBs
MR4- An RGB LED on the Smart Feeder indicates the status of the component database
MR5-Smart Feeder is easily powered on the pick and place machine and on the shelf
MR6-Components are dispensed from the Smart Feeder at a fast enough pace to be used on a pick and place machine
MR7- Additional attachments for Smart Feeder shall be cost effective for small PCB manufacturers
Engineering Requirements
ER1-Smart Feeder correctly counts 50 out of 50 components dispensed (MR1)
ER2-Each Smart Feeder updates the remaining component count every 30 minutes (MR2)
ER3- Smart Feeder will have a max width of 2 cm to not interfere with surrounding feeders on pick and place machine (MR3)
ER4- The RGB LED will be updated in real time. Red indicates the database is not currently updated, green indicates that it is (MR4)
ER5- 2-position standard terminal blocks will be used to apply power to the Smart Feeder on the pick and place machine and shelf (MR5)
ER6- Smart Feeder is able to dispense components at a speed of at least 1 component per second (MR6)
ER7- Smart Feeder attachments will not exceed $100 (MR7)
