ROI Calculation Logic

Assuming installation/removal of a medium-scale temporary bridge, conventional methods require 5 person-days. This technology could reduce it to 2 person-days. With labor costs at ~$333/person-day (AI est.), this is a ~$1K/site reduction (AI est.). Applied across 100 sites annually, this could yield ~$100K/year in cost savings (AI est.).

Speed to Market
6× faster than in-house development
This technology's panel unit structure, which is expandable in both vertical and horizontal directions, is thoroughly disclosed in the patent specification. Its fundamental design philosophy and operating principles are already established, significantly reducing the time and cost required for new development. By applying existing manufacturing technologies and general-purpose materials, early commercialization is feasible. The modular structure provides a strong foundation for streamlining prototyping and validation processes, shortening time to market.
