Conceptual & Detailed Design Phases
Design Phase 3 - Conceptual Design
Substitute:
Planks instead of sheets of plywood
Combine:
Add blocks to connect ramp to steps, add on/off ramp lip
Adapt:
Cornhole board design with folding leg supports
Move Handle
Modify:
On ramp longer than off ramp
Self-adhesive Tread (grip tape)
Put to Another Use:
Pop-up shops, carts, wagons
Eliminate:
2 separate plank sections instead of 1
2 rails instead of one plank
Reverse:
Stored outside instead of inside
RESEARCH & NOTES
ADA Compliance Regulations (Avery)
Run = 36'' between handrail
Rise = 30'' per run
Slope = Elevation change for every 12'
Carpet: (Avery)
Carpet or carpet tile shall be securely attached and shall have a firm cushion, pad, or backing or no cushion or pad. Carpet or carpet tile shall have a level loop, textured loop, level cut pile, or level cut/uncut pile texture. Pile height shall be 1/2 inch (13 mm) maximum. Exposed edges of carpet shall be fastened to floor surfaces and shall have trim on the entire length of the exposed edge. Carpet edge trim shall comply with 303.
Materials - Tread (Stephanie)
"Grip tape is a sandpaper-like material with an adhesive underside that sticks onto the top of your skateboard deck to help your shoes grip to the board, ensuring you don’t slide off while you skate. Grip tape is usually made of silicon carbide. It’s not known who started sticking sandpaper onto a skateboard deck as a solution to slipping, but it emerged sometime in the ’70s and marked the beginning of the evolution of grip tape as we know it today."
Construction - Planks (American Planking 3.75-in x 1-ft Red Cedar Aromatic Cedar Tongue and Groove Wall Plank (Coverage Area: 15-sq ft ), bracing, hinging on/off ramps ( Can't figure out until measurements for ramp are finalized) (Stephanie)
Frame structure (plans)
Survey Community - Google Form (Stephanie/Rocky)
Have you ever needed/wanted to transport things in a wheeled cart or wagon?
How do you get wheeled items into the building?
Would you use a ramp to ease the process if it was available?
Max weight limit
Angle of the steps (Rocky) - confirm math
Rise = 16 1/4
Run = 33 3/4 + 12 1/2
Hypotenuse = 49
Angle = 19.4 degrees?
Measure Sidewalk Area (Stephanie)
Find new measurements for cart/wagon/shop (Stephanie)
Revisit Storage Areas (Mrs. Hall's Room, or Art room closet - outdoor?) (Rocky)
NEW USERS/SPECIFICATIONS
Maintenance - Event Setup
Teachers - Video Production
Fox/Hound Officers - Choosings, Event Setup
Housekeeping
Student Life - Pop Up Shop
Utility Cart / Folding Wagon
Hand Truck / Furniture Dolly

The ramp will be able to fold in half.
Design Phase 4 - Detailed Design
Progress
Stephanie - Storage area ( Outside storage space gives easier access and has logical thinking), holders (for my design giving extra support for users) , and dimension specifics ( Straightforward out our dimension specifics. )
Rocky - Storage area and overall general build of the ramp and known materials. We have a general consensus on the materials we will be using (wood type, grip tape, etc). We found a storage box that will fit our designs.
Avery - Storage area, and finding the hinges. Finding apporiate materials for the source
Issues
Stephanie - Need to make sure supports are able to hold proper weight and is durable enough.
Rocky - Location of the hinge and weight. Due to the placement of the hinge on our prototypes, it makes a very weak area in a non-ideal area. Due to that weak area, it makes maximum weight and issue.
Avery - Distrubition of weight furthers the location of the hinge. Need to design final hinge/joint combustion to address the weakness of the ramp
Goals
Stephanie - Find design for hinging and find way to ensure supports are stable and strong for users and making sure a fast/efficient way for set up for our ramp.
Rocky - Combine or make a compromise with both ramp prototypes and designs. Build a functioning ramp that can hold the amount of sand bags Ms. Riley can put on her folding wagon.
Avery - Test two designs one with a separte block under the middle and a proposed longer, shorter ramp (hinge in a different location) to see the accurateness of each design
Tasks & Responsibilities:
STEP 1: Finalize design
What is finalized? container, handle, hinge, lip (1x2)
What is not finalized?
Hinge and placement
Pull measurements on the stairs
Pull measurement of inside container = length: 43.5 in. width: 21 in.
Where to place lip - must be at least on top
Support blocks
Separate pieces or folding (new hardware)
STEP 2: Create two new prototypes - 1 with 8'' material, 1 with 10'' material
STEP 3: Test prototype
Determine which suits the max weight limit
STEP 4: Make changes to final design
STEP 5: Deliver final project
