The primary project goal was to reduce the cost per unit of the structural foundation (sublane) of the Route 66 miniature bowling lane by 10%. Additional project goals were: 1) reducing the cubic volume for shipping, (2) reducing the lane assembly time, and 3) maintaining current 10 to 15-year product life. Ten sublane sections are used to assemble two lanes of a Route 66 unit. The project constraints included: 1) maintaining outside height, width and length of the sublanes, 2) load bearing strength greater than or close to the current design and 3) no significant change in manufacturing processes. After engineering analysis of the current design, material properties, and material costs, the best solution was to reduce thickness of the current Oriented Strand Board (OSB) material from a custom 1.375” thickness to a standard material thickness of 1.25”. In addition, three modifications were made to meet the design constraints: 1) increasing the length of the cross-wise vertical boards by 0.25”, 2) extending the length of the kickback brackets by 0.125” and 3) increasing the thickness of the sublane particle board material from 1” to 1.25” to maintain the appropriate height. Final material cost savings obtained was 54%. Additionally, weight was reduced by 13% (234.6 lbs.) exceeding target of 6%, cubic volume by 57 cf3 (2.4%) less that target of 15%, and shipping length by 22% (157”) exceeding 15% project target.
