Design TaskProblem Recognition

Paper release with offset no more than 5mm either direction.

Mission StatementOur mission is to provide the most convenient and cost productive way to measure and monitor the offset of paper stacks, that they never exceed more than a 5 mm offset in the x-axis direction.

Customer NeedEase of handling paper stacks.Ease of separation of stacks.

Design Task (cont.)

Design SpecificationsA series of lasers are shot from the bottom of the design to the top of the design. If there are laser's which do not go completely from the bottom to the top the stacks must be off in the y direction to some amount or the x direction by more than 5mm(0.196850394 inches). If this is the case the designed machine will alert the employee operating it for correction of the stacks.

LasersA laser that will shoot from the bottom of the stack to the top where there will be a simple detection device that will register the lack of laser for an imperfection of the stack along the y axis and/or x axis.

A laser that will shoot from the top of the stack to the bottom where there will be a simple detection device that will register the lack of laser for an imperfection of the stack along the y axis and/or x axis.

Laser (cont.)A gel wall that can be applied to the stack which will clearly show if there is an imperfection in the stack by observation of any “bulges.”

A simple metal straight edge that can be set along the stack edge to detect if there is an offset.

Two set walls along the y axis with “drop walls” along the x axis that will be composed of a light weight material which will not set perfectly straight if there are any imperfections.

Cost AnalysisLow Cost

Laser Cost +$6

With the price of the Xerox being so high the small price increase should be relatively uncontested by customers.

Summary We found lasers would be the most efficient and cost effective way to measure stacks.

Should not raise price by a significant price.

A portable design allows for movement between machines which decreases the number of necessary designs.
