Bad Design


As seen in the pictures below, the drawing table has a fault in its design. as seen in the first two pictures the rulers are lying flat on the table as they are suppose to however they are not using the full extent of the drawing space. When the operator goes to use the full extent of the space the small wheel on the end of the arm, at the bottom of each picture, rolls off the table lifting the rulers off of the table and creating a loud banging noise.

BEFORE (Wheel on the table)

AFTER (Wheel rolled off the table)



To correct this design is quite simply to have a longer arm that is connected to the wheel. this way the full extent of the table can be used in a stable and safe fashion. The longer arm design is shown below.
