  2. 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. Band Wrench Advantages: -Fits most filters -effective -inexpensive Disadvantages: -Hard to fit in tight places -two hands required 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.

  4. Screw Punch Filter clamp 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 punch punch drive hose Screw threads turn 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.

  5. Cable Ratchet Advantages: -mechanical punch system -adjustable gripper for different orientations of filters Disadvantages: -more complex and expensive -multiple moving parts 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.

  6. Ratchet Step 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 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.

  8. Drainage Systems mechanical pump (drill driven) Gravity drained hose Advantages: -cheap -easy to use Disadvantages: -need large hose to drain -slow drain Advantages: -fast drain time Disadvantages: -need extra tool to operate -added expense

  9. Drainage Systems air pump (venturi) Hand Pump Advantages: -fast drain time Disadvantages: -added cost Advantages: -fast drain time Disadvantages: -need extra tool to operate
