ROI Calculation Logic

This technology could significantly reduce battery replacement and external charging costs. For a large-scale shared bicycle operator, assuming $20/bicycle/year in charging costs for 10,000 bicycles, this could lead to ~$200K/year in cost savings (AI est.). Factoring in extended usage and new service revenue, the total economic impact could exceed ~$150K/year (AI est.).

Speed to Market
6× faster than in-house development
This technology has proven feasibility through prototyping, with its basic operating principles and effects already validated. This could shorten development time by approximately 2.5 years compared to starting from scratch. Established design data for the blades and stand structure enable licensees to significantly accelerate the design and development phases, facilitating rapid market entry.
