ROI Calculation Logic

Conventional fatigue testing requires stopping the apparatus for moment amplitude changes, incurring an average 30-minute stop time per instance. For 2,000 tests annually with an average of 5 setting changes, this totals 500 hours of annual downtime. At a labor cost of $35/hour (AI est.) (5,000 JPY/hour ÷ 150), this results in $20K/year (AI est.) in direct operational cost. This technology eliminates such downtime. Additionally, a 20% reduction in testing duration could shorten new product development lead time, preventing an estimated $130K/year (AI est.) in opportunity losses. The combined economic impact is estimated at $150K/year (AI est.).

Speed to Market
6× faster than in-house development
This patented technology, with its detailed operating principles and components, can be rapidly integrated into existing fatigue testing machines through design modifications.
