2. Problem Statement There are over 25 million children under the age of 5 in the United States, many of these children are taken out to restaurants to eat on a regular basis. These children need the help of a booster seat to be able to reach the table while eating. However, the current booster seats lack in functionality and versatility.

3. Past & Present Solution There are current booster seats that are made from both Plastic & Wood. They can Include “slide ins”, straps, and buckles.

4. Design parameters Criteria for when we know we have accomplished our Goal for the Design  Safe for Small Children under 5  Holds onto Wooden Seats  Holds Carriage  Stackable  Adjustable Height  Cost Efficient  Minimum Set up time

5. Project Proposal As of March 2010, there were over 20 million families with children in the United States. Many of these families go out to eat at restaurants on a regular basis. The problem these families face is that small children do not have a safe and functional booster seat to sit in. The booster seats already put in place by restaurants do not have a safe way to hold children from new born to 5 years old. The current booster seats does not have a secure way to hold the child and they do not address the issue of holding children of multiple ages. The overall design of our group would address the versatility and functionality of booster seats.

6. Building Plan 1.Cut a 16’’ by 13’’ base out of the composite wood sample. 2.Cut four 1’’x 1.5’’x 11’’ pieces of spruce wood. 3.Cut four 1’’x1.5’’x7’’ pieces of spruce wood. 4.Rout incisions on the 7’’ pieces and make the end of the 11’’ pieces fit into the routed slot. Slide the 11’’ pieces into the 7’’ in order to create the two sides of the seat. 5.Cut two 1’’x 1.5’’x13’’ pieces of spruce wood. 6.Cut two 1’’x1.5’’x8’’ pieces of spruce wood. 7.Rout incisions on the 8’’ pieces and make the ends of the 13’’ piece fit into the slot to create the back wall of the seat. 8.Cut a 1’’x1.5’’x16 piece of spruce wood. Beginning an inch a way from each side make a 1’’ deep cut out 1.5’’ wide. 9.Set the back wall inside of the cut-outs, drill a hole on each side, and put a nail in the hole to act as a hinge. 10.Cut two 1’’x2.5’’x13’’ pieces of spruce. Beginning from each side, make a.75’’ deep cut with a width of 1.5’’. 11.Set the side walls into the cut outs, drill a hole, and insert a nail on each side to act as a hinge. 12.Drill each wall into the base board to create the next for the booster seat. 13.Drill four hole on the underside of the base board at an angle of 10 degrees. Screw the paint extenders in the hole to serve as legs.

7. Prototype  Addresses Problem Statement Our design achieves what we set out to accomplish in the problem statement. We have created a product that is now safer and more efficient than the past booster seats offered in various establishments.  Functions Has Adjustable leg heights Removable Booster Seat Easily Cleanable Surfaces Stackable  Criteria & Constraints Safe Holds Booster Seats Holds Baby Carriage Stackable Adjustable height Minimum set up time Cost efficient

9. Testing Plan To test the strength of the legs, increase the weight in the seat by increments of 5lbs. up to 50lbs.  To test the safety of the seat, add pressure to the side at angles of 115 degrees, 90 degrees, 75 degrees, 45 degrees, 30 degrees and so on until it tips over.  These test will allow us to see where improvements are needed in order to make the seat as safe as possible for all users.

13. Surveyed Results

14. Our Market Research shows great results. We were very pleased with the responses we collected. Over 50% of the respondents currently have children and have put their children in booster seats at restaurants. Again, over 50% said that they were concerned with the safety of the booster seat. These results give us the initiative we need to further our project. Surveyed Results

15. Solution Justification After heavy revision on the basis for the finished legs, we ended up going with a recycled walker that we braced together with PVC pipes. This added further stability and functionality regarding the height. Our finished product now offers plain seating, can hold booster seat, and can hold a baby carrier safely.
