ABOUT / COMPANY PROFILE

Waterson-invincible

STRUCTURE IS THE BONE, DESIGN IS THE SOUL

Backed by parent company Liyuan Technology — founded in 1979 with over 40 years in precision casting — Waterson Group has, since 2009, dedicated 17 years to stainless steel hinge innovation. Winvincible, the group's structural innovation and R&D center, spent five years (2020–2025) bringing the "One Axis, Modular Symbiosis" philosophy to four leaf structures (D / K / M / R) combined with three DM catalog function sets (HSW / TSW / LSW) — delivering a new generation of standardized, automated, durable and install-friendly hinges for the world's door-control market.

MDEA Installation Technology

MULTIFUNCTION DOUBLE EXPANSION ANCHOR · EASILY & FRIENDLY

Installed With One 5 mm Hex Wrench

Clockwise rotation sets the spring torque. The floating spindle auto-matches brake force to the stored torque — when the closing speed feels right, you're done. No complicated adjustment required.

Automatic Closing or Opening From a Single Hinge

One hinge alone delivers either automatic closing (90° → 0°) or automatic opening (0° → 90°) — no extra accessories needed.

TS Pure Mechanical Structure — Near-Lifetime Warranty

The TS module's purely mechanical structure is extremely long-lived and virtually indestructible. Waterson fans can replace a worn unit simply by covering round-trip shipping — effectively a lifetime warranty.

Time & Cost Saving · Dual-Expansion Anchoring

MDEA dual-expansion anchoring means one-time positioning, greatly cutting installation labor and rework cost. With D / K / M / R hinges no special washer is needed — it locks directly into the three grooves on the leaf; general universal mounting requires the dedicated washer for optimal anchoring.

INVINCIBLE GLOBAL LAUNCH

Waterson's New Hinge Structure System

HSW+ / HSW · TSW+ / TSW · LSW+ / LSW

Waterson Chen
CEO & Founder
Opening

Hello everyone, I am Waterson Chen, CEO of Waterson and the founder of this new hinge system. Today, I would like to introduce Waterson's new modular hinge structure system:

HSW+ / HSW · TSW+ / TSW · LSW+ / LSW
Module Definitions
  • W: Optional concealed wiring.
  • H: Hydraulic damping brake structure.
  • T: Pure mechanical braking structure integrated with a safety pin device, allowing temporary door stopping and added protection against unauthorized entry.
  • L: Electronic hinge lock integrated with an emergency escape device. In an emergency, users can pull down the escape safety pin and push the door open immediately.
  • S: Stored torsion power mechanism.
  • +: Indicates two pivot-core types. The core marked "+" adds a special dual-stage gear conversion mechanism designed for the D hinge; cores without "+" (H/T/S/L/W) have no dual-stage gear conversion.

Both the A-type and B-type pivot-core modules are suitable for the K, M, L, and R hinges; only the A-type module pivot fits the D hinge. When applied to the D, K, M, and R hinges, nearly 100% of the internal space is fully utilized. This leaves competitors almost no extra space to modify or redesign. The structure and operating principle are unique and difficult for ordinary technicians to fully understand.

Concealed Wiring Options
  • UL-10362: Teflon, heat resistant up to 250°C, AWG 28.
  • UL-1569: PVC, heat resistant up to 105°C, AWG 26.

The concealed wire harness consists of 12 color-coded wires arranged into one flat ribbon cable. The 12 wire colors are based on the current U.S. market color standard used by ASSA ABLOY. Waterson commissioned manufacturers to develop custom tooling and samples, going through countless improvements and mold adjustments before finally achieving success.

Easy Installation with MDEA

When installed between the door leaf and door frame, Waterson's MDEA — Maji Double-Fix Anchor — makes installation fast, safe, adjustable, and user-friendly.

With only a 5 mm hex wrench, the installer simply rotates clockwise to build torsion force until the door automatically closes or opens. If the closing or opening speed is satisfactory, no further adjustment is needed. Because the pivot core operates in a floating condition, the braking force automatically adjusts according to the torsion force.

If the user feels the door closes too quickly, the brake speed can be fine-tuned from the opposite end using a 5 mm hex wrench. Each HSW+, TSW+, and related module is an independent mechanical structure with its own stored torsion and damping/braking function. In simple terms, one hinge alone can achieve closing from 90° to 0° or opening from 0° to 90°.

For a door using two hinges, Waterson recommends the TS pure mechanical structure for long life, high durability, and lower cost. It is nearly impossible to wear out and may even be offered with a lifetime warranty for Waterson fans, with only round-trip shipping required for replacement.

W concealed wiring is an optional accessory. The same pivot-core design can be shared across D, K, M, and R hinges, allowing different hinge appearances while still providing premium automatic opening or closing functions at the most competitive price. Waterson has completed the full design and is ready for mass production.

WA+ Passion Fruit and MDEA Demonstration

Waterson will also personally use MDEA Maji Double-Fix Anchors to build a three-dimensional farm trellis system for WA+ passion fruit. This project will demonstrate how technology-based management can transform plant growth from zero to one.

The goal is to create standardized WA+ passion fruit, with consistent size and quality. Although many may consider this a "mission impossible," Waterson is willing to accept the challenge and prove that it can be done. In the future, Waterson will livestream the construction and growth process for fans to watch. Carefully selected WA+ passion fruit will be packed as 10-piece gift sets and shared with fans who love Waterson Hinge, allowing everyone to experience the founder's vision, dedication, and long-term strategy.

Invincible Global Launch

Waterson will officially announce this new product system to the global market at the 2026 Taiwan International Interior Design Expo, TIDE, from July 9 to July 12, in the Year of Bing-Wu.

Fans and partners who miss this opportunity to cooperate with Waterson in the Year of Bing-Wu may have to wait another 60 years. Let us seize this opportunity together and stand on the front line of the global market.
