2. D-Oily Tools 02/01/06 Simple Pliers Advantages: -very durable -requires little technical skill -inexpensive Disadvantages: -Bulky -Can require large amounts of force The Simple Pliers design consists of a punch that attaches either side of the pliers. The oil filter is punctured by squeezing the pliers manually, and the oil drains out by means of a hose under the influence of gravity.

3. D-Oily Tools 02/01/06 Band Wrench The idea is to use a band type oil filter wrench to clamp on and punch a hole in an oil filter. A hose would be connected to the punch to drain the oil out then the wrench could be turned to loosen the filter. Advantages: -Fits most filters -effective -inexpensive Disadvantages: -Hard to fit in tight places -two hands required

4. D-Oily Tools 02/01/06 Screw Punch punch drive turn Screw threads hose punch Filter clamp This design uses a band type oil filter wrench to hold the filter, while a screwing Mechanism is used to insert the punch into the filter. Advantages: -Lower force requirement -Punch depth adjustable by user -Adaptable to different sizes Disadvantages: -Prone to fouling -Poor directionality -Operation is slow -Fairly complex manufacturing requirements

5. D-Oily Tools 02/01/06 Cable Ratchet The hole is punctured in the oil filter by means of tightening a cable with a ratchet system. The cable pulls on an arm that punches through the filter. Advantages: -mechanical punch system -adjustable gripper for different orientations of filters Disadvantages: -more complex and expensive -multiple moving parts

6. D-Oily Tools 02/01/06 Ratchet Step The clamp is tightened by squeezing the handle. The clamp tightens in small steps. Once the clamp is tight enough, the punch punctures the filter and the oil drains out. Advantages: -mechanical punch system -requires less force than pliers Disadvantages: -bulky, hard to fit in small places -ratchet mechanism could break or rust -poor directionality
