2. What Is It? A Flagpole Which: Allows flag to be raised and lowered Allows flag to rotate 360° Is five to eight feet tall Will withstand 30 kt. Winds Is corrosive resistant Why? A wrapped flag poses a safety hazard to: Divers because flag is not visible Boat crew due to rough seas and height of pole Who would want it? All commercial and recreational scuba divers who own their own boat The Unwrapable Flagpole

3. Material selection Researches and selects materials Selects machining processes for production Lifting the Flag This subsystem raises and lowers the flag Rotation of the Flag This subsystem allows the flag to rotate 360°

4. Internal Pulley Plusses: No possibility of wrapping Able to adapt to existing flagpoles Aesthetically pleasing Minuses Collars require tight tolerances

5. Rigid Non-Rotating Flagpole Plusses: Does not require complex lifting or rotating mechanism Minuses Flags must be extremely heavy to withstand wind forces Flags pose safety hazard when lowered

6. Slotted Flagpole Plusses: Simpler design than IPWO Minuses: Slot in pole hurts rigidity Flag only secure when fully raised Patented

7. Spinning Shaft Plusses: Does not require complex lifting mechanism Simple modification to existing pole Minuses: Bearing vulnerable to corrosive elements Moment created by wind forces could cause bearing to bind Patented

8. Slotted Flag Pole Proves validity of internal pulley Eliminates one of prime concepts Thinking is similar to IPWO meaning design is feasible and practical

9. Ergonomics Product must require minimum input from user Must be user friendly Performance Flag must rotate with minimum of wind Flag must not snag Manufacturability Minimum of tooling Minimum of resources Ease of maintenance Must be user serviceable with minimum of special tools Must contain minimal parts Cost Material, manufacturing, and design cost Aesthetics Overall appearance

10. Internal Pulley with Overhead Lifting Ranked first by P-Select for both scenarios Meets or exceeds all criteria and specifications Utilizes existing technology Two other promising concepts were patented

11. Material Considerations Method of Production Establishing tolerances so that inner and outer collars do not bind Does the inner collar need a guide? Should the line be attached to the upper and lower collars
