Articulate injections that can relieve the conflict while meeting the objective.

204 CHAPTER 7 Concept Generation Principle 10. Prior action a. Carry out the required action in advance in full, or at least in part

b. Arrange objects so they can go into action without time loss

waiting for action This leads to the idea of having the clamp automatically move so the jaws come into contact with the work prior action and then the grip force is translated into high clamping force with small motion. This is similar to the first idea, but the prior motion is automated. Principle 17. Moving to a new dimension a. Remove problems in moving an object in a line by two- dimensional movement along a plane b–d. Others are not important here This leads to the idea of using a linkage to get a more complex motion than purely linear. A linkage is used to get the jaws in contact with the work and then the small motion with high force is action as is typical with a one-handed clamp. There are many other ideas to be discovered by working through the inventive principles and other TRIZ techniques see Section 7.11 for TRIZ information sources. 7.8 BUILDING A MORPHOLOGY The technique presented here uses the functions identified to foster ideas. It is a very powerful method that can be used formally, as presented here, or informally as part of everyday thinking. There are three steps to this technique. The first step is to list the decomposed functions that must be accomplished. The second step is to find as many concepts as possible that can provide each function identified in the decomposition. The third is to combine these individual concepts into overall concepts that meet all the functional requirements. The design engineer’s knowl- edge and creativity are crucial here, as the ideas generated are the basis for the remainder of the design evolution. This technique is often called the “morpho- logical method,” and the resulting table a “morphology,” which means “a study of form or structure.” A partial Morphology for the redesign of the one-handed bar clamp is presented in Figure 7.21. This is highly modified from the morphol- ogy done at Irwin to protect their intellectual property. A blank morphology is available as a template. 7.8.1 Step 1: Decompose the Function The first half of this chapter details this step. For the one-handed clamp exam- ple, the function was decomposed in Fig. 7.11. The first four functions in that figure are
