Lifting and moving 100-pound sacks of coffee beans is back-breaking work. Repeatedly grasping, hoisting, and piling the sacks — heavy and awkward with their shifting contents — is a significant health issue for workers. How might the unloading of these and similar sorts of cargo be made automatic, and ease the burden on workers lugging such heavy loads?
Joining up with a colleague in an interdepartmental research center, researchers in civil and industrial engineering at the University of Pisa in Italy decided to take up this challenging problem. Specifically, they set themselves the task of developing a “gripper” that could grasp coffee sacks made of a porous material (jute), ranging in weight from 50 pounds to 170 pounds. The gripper needed to work quickly (grasping or releasing in less than 3 seconds), and without excessively tearing or damaging the jute material.
But the enterprising researchers weren’t just on the quest of a new gripper: they were using this challenge to test-drive a new “creativity support” method they were developing. Meant to help designers reach into unexplored idea territory, the multi-step method provides a structured guide for using abstraction and analogy to more effectively generate innovative design concepts.
