Recently, good news arrived from the European Patent Office (EPO). After nearly four‑years of rigorous examination, Tiantie Co., Ltd. ’s invention patent titled "BALLAST BED RESONATOR CONFIGURATION METHOD" (European Patent No. EP 4365560) was officially granted on July 15, 2026.

This is the company’s first independently filed international invention patent. It marks a significant global achievement for the enterprise as it deepens its commitment to rail transit vibration and noise reduction and implements its technology‑driven corporate‑development strategy.

The core innovation delivers a scientific, efficient and targeted solution for ballast‑bed resonator deployment. High‑precision sensors collect vibration data from tracks and adjacent sensitive buildings during train operation. Through frequency‑domain analysis of measured vibration signals, the intrinsic resonant frequencies of buildings impacted by railway traffic are identified. A precise calculation model is then established to determine the optimal installation parameters for resonators.

The innovative approach effectively counteracts building vibration induced by passing trains, fundamentally mitigating low‑frequency resonance and secondary noise for better living conditions alongside railway lines. Well‑suited for retrofitting existing rail tracks, the solution features easy‑to‑implement installation and low‑cost advantages. Construction work can proceed without disrupting normal railway operation, bringing both social and commercial benefits with broad market application potential.

The European patent grant serves as solid recognition of Tian Tie Technology’s R&D competence and innovation capacity. It forms a critical milestone in the company’s international expansion, building solid IP legal protection for bidding on high‑end overseas projects across Europe and worldwide.

Building on this overseas patent breakthrough, Tian Tie Technology will continue pursuing innovation‑driven development. The company will accelerate the industrialization of proprietary core technologies and empower global railway infrastructure with high‑value independent intellectual property, advancing toward the vision of becoming a world‑class comprehensive rail transit solution provider.
