ROI Calculation Logic

Conventional pipe detachment from the buried head typically requires 2 field operators for an average of 2 hours daily. This technology virtually eliminates this task, potentially saving ~$6.5K/site/year (AI est.) (based on an estimated 1M JPY/site/year saving). Applying this across 25 sites could yield ~$165K/year (AI est.) in cost savings.

Speed to Market
4× faster than in-house development
This technology has demonstrated proven performance in prototype trials, validating its fundamental operating principles and effectiveness. The buried head structure and the pipe retention/release mechanism are well-established, eliminating the need for licensees to conduct R&D from scratch. Adopting this patented technology could significantly shorten the 3+ years typically required for in-house development, allowing companies to focus on integration into existing construction processes and achieve market entry in approximately 10 months.

Technical Feasibility
This technology employs a modular design, featuring a first arm and a second arm connectable to existing traction mechanisms (e.g., construction machinery), along with a buried head. This allows for relatively easy integration by incorporating the buried head component into existing heavy machinery or vehicles, without requiring extensive equipment overhauls. The structure described in the patent claims is based on general mechanical design principles, indicating low technical hurdles for adoption.
Success Scenario
Upon adopting this technology, labor-saving in drainage pipe laying operations could advance significantly. Specifically, multiple operators previously required for the pipe detachment process could be reallocated to other tasks. This is estimated to shorten overall project timelines by up to 20% and potentially increase the annual number of completed projects by 1.2 times. Consequently, this technology is expected to greatly contribute to business continuity and competitive strength in the construction industry, which faces severe labor shortages.
