RIT MSD IIFINAL REVIEW

ESTAR WIDE FORMAT SHIPPING CONTAINER

Scope Develop universal package to accommodate new

products Standardize pack-to-ship process

Overview Gathered needs and specs Concept development Design selection Engineering analysis Detailed design

MSD I RECAP

Impact Tests performed at Kodak10-15 impacts2200 lb rollMax acceleration of 13g measured at base of package

Translates to an acceleration of 2 for rollFirst impact cracked the plywood saddle supportsFollowing impacts didn’t cause further damage,

package remained intact for well over goal of 5 uses

IMPACT TESTING - RESULTS

Package absorbs a substantial amount of energy Saddle support thickened to increase strength at

failure pointSmall saddle area makes loading somewhat

diffi cult Saddle thickened to ensure adequate area for core Core length measured – out of spec, addressed with

core manufactureresHorseshoes with connection at base created a

gap after impacts Horseshoes will be free-floating going forward so they

can return to their original positions

IMPACT TESTING – DESIGN IMPLICATIONS

SPEC DOCUMENT

See needs and specs status check document

3 hours, double stacked container, movement in vertical direction only

Top roll collapse at 24 minutes Likely due to core plug failure due to compressive stress,

followed by failure of core Opposite side of core showed signs of similar damage but not

total failure Wear seen around circumference of core suggests roll rotated

during testPackage condition

No failure of components No cracking Straps intact Noticeable wear due to collapsed roll vibrating against

components

VIBRATION TEST RESULTS

VIBRATION TEST RESULTS

Core Plug

Core movement in y-direction may be contributing factor to failure Solution: reduce/eliminate horseshoe clearance on core to

restrict movementCore and core plug failure

Solution: more robust core plug Solution: larger saddle contact area (would affect max roll

width)

VIBRATION TEST - DESIGN IMPLICATIONS

NEW PACKAGE – 3D

Overall height reduced by 4”Horseshoe now secures the roll from above

Current unit cost $250 – goal of $120 In order to drive unit price down, package reuse must

be emphasized Lean toward higher volume customers to make return

feasiblePackage design should be bid out to multiple vendors

for potential cost savings

Increased throughput, reduced CTReduction of DVB due to repack

COST/BENEFIT

Latest design - vibration and impact testingLarger rolls

Package design must be scaled to fitConsider cost benefit analysisReview SOP, train operatorsSeek customer approval for new package
