This presentation outlines the engineering analysis and design considerations for a customized container system. Key aspects include an overview of finished layout drawings, total force and deflection analyses, required clamping force calculations, and buckle tensile strength evaluations. The report details tolerances for sealing and structural integrity, weight and dimensions of the components, and material selection based on engineering software insights. Solutions to concerns regarding structural supports and load distribution are discussed. Deliverables expected next week include part drawings and ongoing website maintenance updates.

Engineering Analysis • Force Analysis Total Force Calculations
Engineering Analysis Cont. • Deflection Analysis
for deflection in the center lines of all lips, this is unacceptably high change quantity of supports from 4 supports to 8 supports Engineering Analysis Cont. • Deflection Analysis Cont.
Engineering Analysis Cont. • Clamping Force
Engineering Analysis Cont. • Buckle Tensile Strength • Total tensile strength must be greater than 600 lb. Assume using steel as the buckle material with a UTS of 120000 psi. • With a safety factor of 2 , d=.08 in
Engineering Analysis Cont. • Buckle Tensile Strength Cont. Use 1/8” diameter rods for the buckles, this will give 1473 lbs of force per side, this yields a total force of 2945 lb.N . Areas of ConcernSolutions -Where the buckle meets the plastic -Expand Contact Area of Buckler -Deflection of the lid. -Brace Lid - Bowing of the sides of the container -Brace sides or choose different materials
Engineering Analysis Cont. • Tolerances • Around the seal, 1/32” • Elsewhere on the box, 1/8” • The cart tolerances are ¼” • Cart Analysis • Cart Load Analysis • F = 28 lbs • F/4 = 7 lbs • Compressive force on all four legs is 7 lbs
Engineering Analysis Cont. • Weight and Dimensions H x W x DWeight -18” x 18” x 18”, Container -18 lbs for box -6” x 6” x 18” , Compressor -10 lbs for compressor -30” x 30” x 20”, Cart -30 lbs for Cart
