ROI Calculation Logic

This technology could reduce fastening time by approximately 40 seconds per connection compared to conventional bolt-and-nut methods. For a line performing 200 fastening operations daily, operating 250 days a year, this translates to an estimated annual reduction of ~555 hours in labor. Multiplying this by an estimated worker hourly rate of ~$35/hour (including labor and indirect costs), a single line could achieve annual cost savings of approximately $20K (AI est.). Deploying across multiple lines or sites could yield over $85K in annual cost savings (AI est.).

Speed to Market
6× faster than in-house development
This technology has already completed prototype verification for both φ10mm steel pin members and φ20mm resin pin members, demonstrating its operational principle and practicality. This significantly shortens the fundamental research and proof-of-concept phases for adopting companies, reducing development risks. It enables a rapid transition from compatibility assessment with existing assembly lines and products to prototype development, allowing for early market entry. This is expected to shorten time-to-market by approximately 2.5 years compared to in-house development.
