Design Question
• The question was posed:
– “…you should also think about how the eraser will
get cleaned. Because the cleaning will be one
driving factor.”
• Design Solution
– Eraser will be detachable to allow for quick
removal and replacement

Eraser for Whiteboard Marker
Patent No.: 6056468
Date Issued: 5/2/00
Felt
strip
Mounting shaft
This patent was granted for a wiper
blade style eraser tool for white
boards. The wiper blade eraser can
be used as a stand alone or it can be
adapted onto an existing marker, as it
has various cross-sections. This
patent is not the entirety of our
invention but is a critical part in terms
of eraser design for the automated
whiteboard wiper to have the least
amount of friction and the highest
removal efficiency with the lowest
number of passes.
Apparatus for cleaning blackboards
Date of Patent: Jun. 14, 1994
Patent No.: US 5,319,820
Brief Description: A system that utilizes a vertically sliding pivoting head mounted to
a frame attached to the surrounding wall. The entire assembly can slide horizontally
while the head can move vertically when cleaning the board. The head can be lifted
off the surface for selective cleaning. The cleaning medium is sponge-like and
removable.

Device
Patent No.:
US 5,607,312
Date of Patent:
Mar. 4, 1997
Brief Description: This device utilizes a frame, a driving roller and a supporting
roller mounted on the frame to drive an endless writing sheet around. An
elongated, fixed eraser which is extended along the width of the sheet is
disposed in the touching of the back surface of the writing sheet. The written
material is thus erased at the back while the sheet is being rolled.
