COLD BOX DESIGNCOLD BOX DESIGN

Dimensions:• Outer Radius = 12 cm.• Height = 22.6 cm.• Overall Volume = 10,200 cm3.• 45% reduction in volume from

design currently in use.• Weight fully loaded = 3.8 lbs.

THERMAL TEST OF COLD BOXTHERMAL TEST OF COLD BOX

• Cold Box tested at 35 °C in convection oven: Maintained internal volume temperature of 2-8 °C for 28 hours.

• Cold Box tested at 50 °C in convection oven: Maintained internal volume temperature of 2-8 °C Maintained internal volume temperature of 2 8 C for 13 hours.

• Test of concept showed that it met specifications set out by PQS and specifications made by the Design TeamDesign Team.

DROP TESTDROP TEST

• Cold box dropped from a height of one Cold box dropped from a height of one meter a total of 26 times

• PQS req ires a rating of 2 (Little to No • PQS requires a rating of 2 (Little to No Damage or Deformation)

f f• Little deformation, no cracks or fractures, slight scuffing on the edge

SIT TEST FOR COLD BOXSIT TEST FOR COLD BOX

• The cold box is often used as a stool by the workers.y• A maximum load of 240 pounds was placed on the

cold box in both horizontal and vertical orientations.

TEST FOR BAMBOO POLESTEST FOR BAMBOO POLES

• The bamboo pole was placed across two tables.p p• A 200-pound man sat on the middle of the pole.• The pole easily supported this weight, which is fifteen

times the weight of the tools.

POCKET TESTINGPOCKET TESTING

• Pockets were continuously overstuffed and left Pockets were continuously overstuffed and left for a period of three weeks

• While o erst ffed items were jammed into the • While overstuffed, items were jammed into the pockets to simulate the fatigue of repeated loadingloading

• Pockets were overloaded to 4 times the d d l l hmaximum individual tool weight

SUMMARYSUMMARY

• Pole carrier provides a visual display of neatly Pole carrier provides a visual display of neatly organized tools used during vaccination outreachesoutreaches

• The backpack carrier can be carried in several different arrangements to best suit the userdifferent arrangements to best suit the user.

• The cold box meets PQS and design team f h l d h ll lspecifications while reducing the overall volume

by almost half of current model.
