Eagle Claw Fishing Reel
Questions for Analysis
1. What is the primary function of the device? How does it accomplish it?
The primary function of the devise is to wind fishing line and allow it to spool out. It accomplishes this by using the bail and spool in conjunction. The bail spins around the circumference of the spool there by winding the fishing line around the spool.
2. List possible user requirements for your product. Provide rationale for each requirement.
1) Smooth action: Comfort 2) Light weight: Heavy is tiring 3) Geared Up: works faster easier to maintain good speed when reeling in. 4) Strong: Reels get mild abuse when taken in and out of boats trucks and cars. 5) Corrosion resistance: water is a pervasive element when fishing. 6) Reliability: It must work when you want it to. 7) Compatibility: A reel is no good if it doesn’t fit on a fishing rod.
3. List possible engineering specifications. Which user requirement(s) do these correlate to?
1) Gear tolerances - Smooth action 2) Weight - Light weight 3) Gear ratio - Geared Up 4) Material properties – Strong Corrosion resistance 5) Vibration – Smooth action 6) Mean time between failures - Reliability 7) Percentage of fishing rods that fit the reel - Compatibility
