- Mydo Sports received Utility Model Patent CN224484815U for a two-stage-transmission slider machine structure on July 14, 2026.
- The patent, co-developed with Beijing Kingsmith, uses a gear-ratio-multiplying drive to amplify magnetic eddy-current resistance and exercise intensity.
- Mydo Sports holds 154 total patents, with recent filings clustering in treadmill folding, elliptical lift, and magnetic-braking innovations.
- The company has participated in 22 bidding projects and maintains 10 active trademarks, signaling a steady commercialization pipeline.
- This marks another joint IP development between two of China’s mid-to-large-scale fitness equipment manufacturers.
July 15, 2026, Xiamen Mydo Sports Equipment Co., Ltd (Mydo Sports) today announced that China’s National Intellectual Property Administration has granted Utility Model Patent No. CN224484815U for “A Slider Machine Structure,” co-developed with Beijing Kingsmith Technology Co., Ltd. Filed on June 3, 2025, and authorized on July 14, 2026, the patent introduces a two-stage transmission system that fundamentally improves how slider machines generate magnetic resistance — delivering tangibly stronger workouts across both home and gym environments.
The newly patented structure comprises an inclined frame, twin sliding carriages, and a resistance module built around a magnetic eddy-current braking mechanism. Unlike conventional single-stage designs, the two-stage transmission assembly — incorporating a drive disc, a magnetically controlled flywheel, and calibrated magnet assemblies — multiplies the gear ratio between the sliding carriages and the flywheel. The result is a substantially higher flywheel rotational speed, which increases the eddy current generated when the flywheel cuts through the magnetic field, producing stronger reverse magnetic resistance for the user. The patent names Chen Jinshui and Peng Qinfeng as inventors, with Xiamen Xinhua Patent & Trademark Agency handling prosecution.
A Growing Innovation Portfolio
Tianyancha corporate data shows that Mydo Sports, founded in July 2009 and headquartered in Haicang District, Xiamen, has accumulated 154 patent filings alongside 10 registered trademarks and 22 bidding-project participations. Registered with RMB 10 million in capital, the medium-sized enterprise operates within the culture, education, arts, and sports equipment manufacturing sector — a category that has seen accelerated IP activity as domestic fitness brands invest heavily in differentiated hardware innovation.
The slider-machine patent represents the second joint IP filing between Mydo Sports and Kingsmith in recent months, reflecting a collaborative R&D pattern that couples Mydo’s manufacturing expertise with complementary engineering capability. Industry observers note that magnetic-resistance slider machines have gained traction in the mid-to-high-end home fitness segment, where noise reduction, maintenance-free operation, and variable-resistance smoothness are key buying criteria.
What the Patent Delivers
The patent’s core advance is the two-stage transmission ratio multiplication. In practice, this means the same user stride effort now drives the magnetic flywheel at a significantly higher RPM, boosting the eddy current volume and, consequently, the opposing magnetic field strength. The design targets a persistent limitation in magnetic-resistance slider trainers: achieving truly challenging resistance levels without resorting to bulky electromagnetic assemblies or friction-based add-ons that compromise the machine’s signature low-noise profile.
“Slider machines sit at the intersection of low-impact cardio and progressive resistance training, but their effectiveness has historically been capped by magnetic-braking saturation,” said a Mydo Sports spokesperson. “This patent directly addresses that ceiling — by rethinking the transmission architecture rather than simply scaling up the magnets, we unlock resistance levels previously achievable only on much larger equipment.”
