The group is tasked with solving the problem of dough emerging misaligned from a 5m long furnace on a metal mesh conveyor belt, as the inside of the furnace is impossible to see. Potential solutions must not impact productivity. It is proposed that adding an oscillating mechanism to the conveyor belt's bearings could cause left and right oscillation, providing self-adjustment to realign the dough within an acceptable range.

In a factory, there is a metal mesh conveyor belt which moves semi- processed material through a 5 meter long furnace. Although material is properly aligned at furnace input, material emerges at the output in a misaligned manner. Since it is difficult to see the inside of the furnace as it is totally encased and extremely hot, nobody knows what happened inside. Provide potential solutions which have no productivity impact. Boundary conditions: - This is a conveyor in a food processing plant. - The semi-processed materials are dough. - The furnace is used to remove moisture from the dough. - The dough is oval in shape. - Only metal mesh conveyor is used to transport materials inside the furnace. - Metal mesh conveyor is not used outside the furnace to save cost.

The forward and backward movement of bearing will cause the left and right oscillation of conveyor, providing a self adjusting mechanism within an acceptable range.
