Table 2-Concept generation Device Process Concept # Description Advantages Disadvantages Alignment of Books 1 One side fixed. One side connected to an inset plate. Only one side needs to move, less moving parts Gap in table surface, centering of the power source might be a problem 2 Both sides move, Each side on a plate, Plates are interconnected to minimize gap Smaller gap in table surface, centering of power source not an issue More moving parts 3 Plate adjusts by a threaded rod in middle, Smooth shafts on either side plates square Threaded rod subject to wear, maintenance 4 Three slots with adjustment knobs plates square More things to adjust Clamp Books 1 Plate connected to actuator bar No additional moving parts, integrated with cutting motion 2 Springs Allows to clamp down to different size stacks Subject to wear Device Process Concept # Description Advantages Disadvantages Cut Corners 1 Linear Actuator Off the shelf, don’t need to convert motion, maintenance, safety Cost 2 Linear actuator, connected through bottom with one rod in the center Bottom setup easy to enclose/maintain, bottom-heavy May have problems with centering with adjustment 3 Linear actuator, connected on the top Table top design Top heavy, maintenance, access to dies
