Problem Description

• Over the past few years, refugees in an un-named
  developing country have been receiving adequate
  food supplies and products except raw eggs.
• Stock, Inc. has been contracted by the host
  government to design and build a Trans-River Egg
  Delivery System (TREDS). Each TREDS may include a
  delivery system and egg protection unit. The
  host government would like to purchase 50 mobile
  TREDS at fair market value from Stock, Inc.
• Due to the fact that the refugee camps are not
  only located across rebel-patrolled rivers, but
  are also quite small and surrounded by
  impenetrable jungles, the TREDS must be accurate
  when delivering raw eggs.
• TREDS must use a renewable energy source - solar,
  wind, hydro, or elastic energy. No external
  power source other than those specified is
  available. Batteries or use of combustible
  materials are not allowed.

Reward

• In its capacity as customer, Stock, Inc. has
  entered into a mutually and divided binding
  contract to purchase the three "Best" TREDS
  designs produced. Stock, Inc. will make offers of
  
• 50 to the design team of the TREDS with the
  Best Design for their design and prototype.
• 25 offer will be made to the design team with
  the "Second Best" design
• 10 will be offered to the team with the "Third
  Best" design.

Objectives

• The objectives of Acme Inc. when building the
  Catapult 1000 are to
• deliver a raw egg to the far side of a 30-foot
  wide river inside a 10-foot diameter camp area
• ensure the egg arrives undamaged
• use of no human power, except one index finger to
  initiate the egg delivery system
• require no more than 60 seconds, after being
  handed a single raw egg, to set up the TREDS

Preliminary Ideas

Preliminary Ideas

• The first idea we had was to use a slingshot type
  of launcher.
• Our second and final idea was a cartoon-based
  catapult used by the great Wile E. Coyote

8
Analysis

• Energy was conserved throughout testing by having
  an stopper located at the back of the catapult.
  This was to ensure consistency with strength,
  distance, and power of the bungee cord.

9
Extra Support

• In order to increase power, we added a second
  bungee cord.

10
Animated Design

• The reason why this design was selected over the
  slingshot method was to ensure maximum
  repeatability and consistency.

11
Performance
Overall as a group, we did pretty well. On Both
attempts, we were within 10 inches of the center
but the egg broke both times. This was a bummer,
but the experience was great.

Final Design

Suggested Improvements

• Use a different brand of water bottle that can
  absorb more damage.
• More cushion for the landing
