Patent ID: 7925478

Claim:
A method performed by a computer system for automatically designing a buffer packing, wherein the buffer packing is used for buffering an object against an impact, comprising: providing in a computer database a static stress table relating static stress values for different test accelerations and test heights for a plurality of buffer materials, a plurality of buffer thicknesses and a plurality of buffer packing types; receiving from a user weight, W of the object to be packed, a user selected buffer material and a user selected buffer packing type; receiving from the user a test height, H for impact testing, a test acceleration, G′ and a safety factor, a′ to be used for the buffer material; calculating by the computer system a buffer thickness, T to provide specified safety factor using a formula T=(H*a′)/G′; obtaining by the computer system, a static stress value, S from the static stress table using the test height H, the test acceleration G′, the calculated buffer thickness T and the user selected buffer material and buffer packing type; calculating by the computer system a buffer area, A for buffering the object against the impact using the formula A=W/S; and designing the buffer packing of the user selected buffer material and buffer packing type using the calculated buffer area and buffer thickness.
