In a team of four, we designed and built a machine that cleaned and applied a consistent epoxy bead to variable length pieces of overhead bin trim for the Boeing 737. The original process was for a person to wipe a piece of gauze across the trim by hand and then use a hand-pumped gun to apply the glue. This led to inconsistent epoxy bead sizes along the length of trim, causing the trim to fall off the overhead bin. In addition, pumping the gun for lengths between 2 and 5 five feet is very strenuous and can be damaging to the operator. Our solution was to use a pneumatic gun mounted to a linear actuator to apply epoxy along a piece of trim that was held down using a vacuum system. To reduce costs, we suggested that Boeing purchase a larger dispensing system instead of using epoxy cartridges. We also suggested that the cleaning process should still be done by hand because a well-functioning system would be costly and a person can better inspect if the piece is clean. Overall, we automated a system to make it more consistent, less harmful to employees, and cost less.
