ROI Calculation Logic

Assuming a 30% reduction in pipe inspection re-inspection rates and a 20% reduction in inspection time compared to conventional methods. If the domestic factory and infrastructure pipe inspection market is approximately $3.5B (AI est.), with inspection costs accounting for 30% (~$1.0B (AI est.)), the overall efficiency improvement from adopting this technology is estimated at ~$1.0M/year (AI est.) (1% of ~$1.0B (AI est.) for efficiency improvement).

Speed to Market
6× faster than in-house development
This technology is structured with clear functional modules for residue removal and imaging, making it easy to combine with existing pipe propulsion and imaging technologies. The patent specification describes concrete concepts for 'propulsion means' and 'residue removal means,' indicating that the basic design for implementation is already established. This means adopting companies would not need to develop from scratch, allowing for early market entry through add-ons or partial modifications to existing inspection systems.
