Mission Statement

• is a company of young, motivated, and
  innovative problem solvers who combine business,
  social, and engineering perspectives to create
  reliable and economical solutions to real world
  problems.

4
Problem Statement

• To develop the concept for an innovative,
  marketable partitioning system that can be used
  as shelter enhancement for disaster victims and
  in other applications, with consideration for
  environmental impact as well as psychological and
  social needs.

5
Present SituationDisaster victims go through
three basic housing stages
Stage 1 - Large open shelters (i.e.
gymnasium) - Little or no privacy and
security - Short stay of approximately one
month
Stage 2 - hotel for one month (expensive)

• Stage 3
• -Rebuilding/home

6
Reactions to Disaster Situations

• Immediate
• -fear
• -disorientation and disbelief
• -difficulty making decisions
• -fatigue
• -anger and resentment

• Long-term
• -depression, anxiety disorders (PTSD)
• -alcoholism
• -relationship difficulties
• -intrusive re-experiencing
• -hyper-arousal
• -dissociation

7
Steps in Designing Portable Housing

• 1. Determine problem
• 2. Conduct research in smaller groups
• 3. Solve!
• 4. Recommend and present solutions to clients

8
Our Solution

• An interior partitioning system
• to break up existing shelters

9
Interior Partitions Because They

• Improve upon present situation
• Add privacy
• Cost less than outdoor alternatives

• Increase amount of time people will spend in
  present shelter, decreasing costs
• Have the possibility of alternate utilizations

10
Choosing the Design

• Design Options

• Objectives
• Privacy
• Security
• Space efficiency
• Portability
• Cost
• Comfort
• Reusability

Floor Plan

• A right isosceles triangle
• Square footage 72
• Sleeps 2

(measurements in inches)
13
Triangle Advantages

• More people, less space
• Fewer panels/walls
• Less wasted space
• Multiple floor layouts

14
Acoustic Properties of Wall Material

• Doubling the mass of a wall improves the sound
  isolation coefficient by 6dB
• Sound is best absorbed by a soft porous material
• A jagged surface will scatter sound and absorb
  undesired resonance
• When sound energy comes in contact with a
  substance it can either be reflected, absorbed,
  or transmitted

15
Factors for Calculating Sound Loss

• Materials used in construction, and their
  properties
• Distance separating materials
• Material surfaces
• Changes of properties between materials

16
Approximate Sound Reduction Due to Materials

• 21 dB at 1,000 Hz
• Reduces sound levels from a regular conversation
  to a whisper
• Areas of understandable speech are broken up

17
Partition Deflection

• Deflection of a panel across a span is directly
  proportional to the force applied to the panel
  and the cube of the length, and inversely
  proportional to the cross sectional area and the
  modulus of elasticity.
• The goal is to minimize deflection across a 12
  foot span while still maintaining an acceptable
  weight and cost.
• The addition of foam and carpeting serve to
  further reduce the deflection of a panel.

Connecting SystemZip Tie Attachment

• Advantages
• Universal to all arrangements
• Inexpensive
• Works with layered panel
• Easy to assemble and disassemble
• No nails, screws, hammers

• Disadvantages
• Not sound proof
• Cannot be reused, which increases cost
• Easily cut, decreasing security

21
Hardware Needed

• Hinges Plastic, 1798A15
• Nuts 1 length, part - 54-546-100, size 8
  hole
• Bolts part 90273A199, size 8, Zinc plated
  steel
• Cable ties part - SKUCT14-120C
• Tools (screwdriver, and scissors or nippers to
  remove the cable ties.)
• Hasps part - 1544A4, Zinc plated steel, size
  8 hole
• Lock (Inside) hook and eye lock, part
  19095A41
• (Outside) combination padlock, part -
  1186A22, key available part - 1186A23

22
Environmental Impacts

• Recycled plastic in the inner and outer layers
• Recyclable foam as sound proofing (virgin
  material).
• Polyethylene Terephthalate (PET)
• Recyclable
• No known hazards (MSDS)
• Polyethylene
• No specific hazards to the environment.
• Polyethylene foam
• Recyclable
• If burned will turn into non polluting
  substances.

23
Health Hazards

• PET
• No carcinogens
• Possible fire hazard
• Polyethylene
• Non toxic
• Polyethylene foam
• Approved for food industry
• Safe for human usage

24
Social Impacts

• Existing Conditions
• -no privacy
• -no adaptable living space
• -no personalized, permanent living space
• -no noise protection
• -no security
• -little space for activity

• -gives a stable, private place to call home
• -encourages community living
• -provides individual storage and security
• -quiet place to rest
• -accommodating living space

25
Social Problems with Tri-Walls

• Increased privacy can cause increased
• -drug/alcohol use
• -level of domestic violence
• -isolationism

26
Community Layout

• Street names will make the shelter more personal
  and give a sense of order
• Labeling each of the Tri-Walls will give each
  person a sense of individuality
• Private space without complete isolation
• Bulletin board for information

27
Disaster Relief Shelter Layout 1

• This design can fit 56 people into the area of a
  small gym.
• This layout requires 3.15 square feet of wall
  material for every square foot of floor space
  enclosed by the partitions.
• The open area in the center can be used as a
  common area where people can gather or for health
  services, mental health services, registration,
  or shelter management.

28
Disaster Relief Shelter Layout 2

• This design can fit 70 people into the same area
  of a small gym.
• The layout shown here only requires 1.65 square
  feet of wall material for every square foot of
  living space enclosed.
• To avoid separating large families who may be in
  need of shelter, partitions can be removed to
  create larger units capable of holding 5 or 10
  residents.
