Constraints

Certain rules we must abide by

1. Alter the original testing rack, but without changing size and

overall design.

2. The timer inputs must not be altered.

3. The structure must support itself.

4. Materials that have a low melting or freezing point cannot be

used.

Problem and Design Statement

To Develop a new testing racks to hold timers. This rack must go

through any environment the timers would go through. L3 Avionics

would put this rack into a testing chamber to see if the structure and

timers and withstand the environmental forces.

Target Consumer and Client Co. would be L3 Communications.

Design Statement: To design, model and build a testing rack which

holds timers through contrasting temperatures and physical

movements.

Material

Hardness

The material will chip and

break easily.

The material has many

spots that can fracture, but

still retains some of the

structure after force has

been applied.

The material can withstand

much outside force, but can

chip or break in small spots.

The material of the structure

can experience much force

and not break.

Sturdiness The structure will fall

multiple times with

consistent outside forces.

The structure cannot stand

too long with consistent

outside forces.

The structure can withstand

much of outside forces, but

will fall if too much force is

applied.

The structure can withstand

much movement without

falling.

Weight The structure would be too

heavy for a person to carry

for more than 2 minutes.

The structure is somewhat

heavy and cannot be held

for too long.

The structure is somewhat

light weight and bearable to

carry.

The structure is light weight

and easy to carry.

Longevity The structure will need

many fixes and will not last

for a long period of time.

The overall product will

need replacing multiple

times.

The structure will last a

moderate amount of time

and will need many fixes.

The structure will last a long

period of time, but will

require a few fixes over

time.

The structure will last a long

period of time before the

need of a replacement.

safety The product has wires

sticking out that are used to

channel power. If there

wires were touched by

someone, the person

operating could receive

serious injuries.

The product has wires and

edges that are not covered

that may harm the user.

The product has certain

edges that may harm the

user.

The structure is all-around

safe for the users and

cannot harm the user if any

way, shape or form.

Chosen Idea

The proposed structure would contain a handle on the top and everything will acquire a new material scheme of Titanium.

The steel base of the structure would be removed.

There will be a plastic sheet covering the wiring in the back of the structure that can slide in and out of place for easy access.

The thickness of the Railings will be reduced.

The Titanium is known for its excellent resistance to corrosion.
