Go Crazy, Take a shower. Try to let the problem germinate. For me, I have new ideas jump in my head when taking a shower or driving in my car.

Concept Generation Example: Power Nailer

A U patent search in the area of nailers revealed several interesting concepts. (this is from the book) One of the patents described a motor-driven double-flywheel nailer. The design in this patent uses the accumulation of Rotational kinetic energy in a flywheel, which is then suddenly converted into translational energy by a friction clutch. The energy is then delivered to the nail with a single impact of a drive pin.

This is a concept classification tree for store or accept energy This is a concept classification tree for store or accept energy. The chemical ones actually exist. They have little cartridges (Like little 22 cartridges.) Stienstra used pneumatic ones

Ideal for homeowners, do-it-yourselfers, and the independent tradesman This tool is easy to use. Ideal for homeowners, do-it-yourselfers, and the independent tradesman Easy to Use, Does everything that a heavy duty tool would do Can also be used to fasten conduit clips, threaded stud, washered power fasteners, and other specialty fasteners Lightweight and portable America's most popular powder actuated tool Uses .22 caliber, necked down, crimped, low velocity power loads. Fastens up to 2 1/2" power fasteners and 2 1/2" washered power fasteners Weighs slightly more than 2 lbs

Possible Solutions for Apply Translational Energy to Nail Single Impact Multiple Impacts Tens or Hundreds Multiple Impacts Hundreds or Thousands Push Twist-Push

This represents a new decomposition that assumes an electrical energy source and the accumulation of energy in the mechanical domain. The text uses morphological analysis (but calls it systematic exploration). As many methods as possible to accomplish each function are determined. Then feasible combinations are identified.

Hey, have they covered all the bases Hey, have they covered all the bases? What about storing energy in a capacitor and then power the solenoid?

Exhibit 6-10 In this solution concept, a solenoid compresses a spring and then releases it repeatedly in order to drive the nail with multiple impacts

Exhibit 6-11 Multiple solutions arising from the combination of a motor with transmission, a spring, and single impact. The motor winds a spinning, accumulating potential energy which is then delivered to the nail in a single blow.

Concept Generation Exercise: Vegetable Peelers

Vegetable Peeler Exercise: Voice of the Customer "Carrots and potatoes are very different." "I cut myself with this one." "I just leave the skin on." "I'm left-handed. I use a knife." "This one is fast, but it takes a lot off." "How do you peel a squash?" "Here's a rusty one." "This looked OK in the store."

Vegetable Peeler Exercise: Key Customer Needs 1. The peeler peels a variety of produce. 2. The peeler can be used ambidextrously. 3. The peeler creates minimal waste. 4. The peeler saves time. 5. The peeler is durable. 6. The peeler is easy to clean. 7. The peeler is safe to use and store. 8. The peeler is comfortable to use. 9. The peeler stays sharp or can be easily sharpened.
