5. Application
The Holditch Theorem
as it relates to motion
planning.
This truck makes wide turns
In order to avoid things like light poles, fire hydrants, signs and
pedestrians during a turn, the driver must make a wide turn.
If we think of the truck as a chord and one side of the road as a
convex shape with the interior side of the road as a new shape, the
truck (or Chord) must stay between the two shapes.
Challenge
The Holditch Theorem
Holditch proved that the area of each red region
depends only on the length of the chosen chord.
It does not depend on the choice of the curve.
Teach a complicated math
theory to a group of teens
and college students in a
traveling math studio.

There are 2 systems that work together in this model. System
1 is mounted in front of System 2 with a spacer in between.
System 1 is the actual interactive model while System 2 is what
allows it to become interactive and turn. Both systems are held
together by threaded rods and bolts.
To complete the display there is a 1/4” -20 tapped hole drilled
into the edge of System 1 after the pieces are chemically bonded
together. A colored liquid is forced into the void of the two
shapes through the hole, completely filling one shape. Silicone
caulk is inserted into the hole to plug it and a 1/4”- 20 threaded
rod is inserted behind that silicone for additional compression
seal.
In System 2, x30 1/4” Acrylic disks (8) are placed between (9)
and (10). System 2 is mounted to the frame of the display by
forcing (10) into the grooves in the mounted grey Al extruded
rods. System one should be stored perpendicular to the ground
with the plug hole pointed towards the sky.
The Model
8. The Holditch Theorem is part of the larger mathematical field of motion planning. Motion planning” is one
of the most frequently studied areas of computational geometry, a field that has grown due to the need of
computer science. There are many variations of the motion planning problem depending on constraints and
circumstances. This is why results addressing length and area in different settings, although not directly
related to real-life problems are important. This project is about a long forgotten but beautiful theorem of
Holditch 1874.
11. Pump System:
The pump pulls nutrient filled water from the lower
reservoir and then pumps it, at pressure to spray
nozzles around the roots of the plant. The water then
drains back into the lower reservoir.
Solution and How it Works
12. The EZgrow allows the user to grow fresh plants
without the use of soil and allows them to maintain
these plants with minimal care.
13. Concept Generation
Bathroom Storage Test
Users were given bathroom
supplies and were told to stock
the bathroom as if it were theirs
and their families’ bathroom.
We learned that people tend to
put the items they used the most
near the bottom of the medicine,
the cabinet is usually hard to
reach, and the cabinet is very
disorganized.
A Growing Need
Growing numbers of aging peoples and increased investment in home
improvement due to a down economy means there is a expanding need
for universal design in the home. Home owners are buying and retrofitting
their properties with value increasing amenities such as medicine cabinets,
central vacuums, bath fans, ironing centers and range hoods. This is one
answer to the growing needs of the aging population.

14. The medicine cabinet works as one
complete system to provide organization
and help the user. The fridge door brings the
content closer to the user, making it easier to
access and read while the sliding magnification
system helps users with low vision be able
to read the content of bottles no matter their
height and without stigmatizing the user.
