OVERVIEW

• Project Information • Product Description • Functional Decomposition Documents • Schematic, flowchart, and spreadsheet

• Bill of Materials • Original Design • Exploded & assembled views, detailed drawings

• Product Criteria • Evaluation Methods • Paul & Beitz and Pugh’s

• Modified Design • Modified Decomposition Documents • Conclusion • References


PROJECT INFORMATION

• What did we do?• Research • De-construct • Model • Document• Brainstorm

• Why did we do it?• Improve functionality of product • Boost Customer Satisfaction

• Problem Statement • Based on the current design, popcorn is being sporadically ejected

from the chute, causing difficulties for any bowl to collect all of the popcorn

DETAILED DRAWING


CRITERIA

Safety (.25)• Unlikely to inflict injury• Avoid any risk of burning • Electrical components shielded from contact

Cost (.15)• Affordable for the average consumer• Minimal capital investment for modification

Time Efficiency (.20)• Cannot slow down cooking process • More popped in less time


CRITERIA

Durability (.10)• Lasts an extended amount of time• Stay intact when moved • Maintain the same work efficiency after being transported

Cleanliness (.10)• Kernels will not be pre-ejected • All popcorn will land in the designated container

Quality (.20)• Majority of kernels popped • No burnt kernels


ALTERNATIVE SOLUTIONS

• Removable flap over the kernel chamber • Deepen the kernel chamber

• Lower height of kernel catcher • Re-shape mouth funnel
