IntroductionIntroduction

Traditionally, while we are playing music, we must stop from time to time to turn over to the next page

Therefore we come up with an idea of making an automatic score flipper.

Motor摩打

Battery cells電池

Switch開關

Small Plate with rubber band covering小膠板和橡皮筋

Belt運輸帶

Our Innovation

Working PrincipleWorking Principle switch is pressed motor will spin and pull the belt to

move small plate on the belt will contact

with the score the friction between the small plate

and score flips the score.

Materials UsedMaterials Usedmainly made of acrylic (light &

hard)

recycled materials such as

◦ motor from a broken CD player and◦ belt taken from a pair of unfit trousers

AdvantagesAdvantages Stop traditional way of flipping scores

from affecting the fluency for the performance.

Help the disabled people as a reading tool

Not Expensive

Convenient & Portable

Can be used with different instruments

How about…

Comparison between LCD Score Comparison between LCD Score Display and OurDisplay and Our

LCD Score Display

Score Flipper

Size of screen/ score

Very small screen, hard to read.

Can be read with ease

Uses Limited by the embedded screen

No limitation, can be used by various kind of instruments

Price (HKD) >2000 <100

Further Investigation

Problem 1: Can the score be flipped in the opposite direction?

Answer: Another set of flipping component with a reverse circuit can be added to our production.

Problem 2: Will the noise made by the product disturb the user while playing?

Answer: To solve this problem, we covered the motor by pieces of plastic. The noise produced is minimized.

Problem 3: Will the production crimple the score while the belt moves?

Answer: The speed of the motor will be adjusted so it will not crimple the paper.
