What the claims cover, in plain language

Claim 1 describes a charging device comprising a waterproof plate, a placement disc, and a rotating rod with a sleeve for a data line. A clockwork spring drives the retraction. The claim specifies three key sub-assemblies:

  1. Adjustment Device: Includes a stabilizing base, plate, and rod that slides into a limiting groove on the sleeve to lock the cable length.
  2. Protection Device: Features a placement base, turntable, and convex blocks that interact with the cable to detect excessive movement.
  3. Deceleration Device: Uses springs and braking plates to physically stop the rotation if the protection device is triggered.

This is a simplified reading for orientation only. The legal scope is defined by the exact claim wording in the official Chinese document.

What this means for US production

This patent was filed only in China and is currently active. Making or selling this specific mechanical configuration in China requires the owner’s permission. However, since there are no corresponding US patents, the design itself is not restricted by this patent in the United States.

Two points to settle early:

  • Other patents may exist. Cable management and retractable reels are broad categories. While this specific combination of a game controller dock with a mechanical over-pull brake is unique here, generic retractable cord designs or specific gaming accessory mounts may be covered by existing US utility patents. A freedom-to-operate (FTO) review is recommended to ensure no infringement of prior art regarding spring-loaded reels or gaming hardware mounts.
  • Component sourcing. The precision required for the locking groove and the spring tension must match the patent’s description to function correctly; off-the-shelf generic reels may not fit the specific geometry described in the claims.

Customization and manufacturing

What can be customized

AreaOptions
Interface TypeUSB-C, Micro-USB, or proprietary console connectors
Cable LengthMaximum extension range determined by spring torque and sleeve size
Housing MaterialABS plastic, PC alloy, or metal casing for durability
Color/FinishMatte black, white, or custom brand colors
MountingDesktop stand, wall-mount bracket, or under-desk clip
LightingLED indicators for charging status (added feature)

Things to plan for (US market)

  • FCC Part 15 - If the device includes wireless charging or any electronic signaling beyond simple power transfer, FCC certification is required. For purely wired mechanical devices, standard electrical safety applies.
  • UL 62368-1 - Audio/video, information technology, and communication technology equipment safety standard. Relevant for the power adapter integration if sold together.
  • California Prop 65 - Plastics and wiring materials must be screened for listed chemicals.
  • ANSI/BIFMA - If marketed as office furniture accessory, stability tests may apply.

How a project runs

  1. Inquiry - Define interface types, cable lengths, and aesthetic requirements.
  2. Design - Model the spring mechanism, locking grooves, and housing tolerances.
  3. Prototype - Test retraction speed, locking strength, and over-pull brake activation.
  4. Pilot Run - Verify durability cycles (e.g., 10,000 extensions/retractions).
  5. Production - Injection molding for housings, winding of cables, assembly of mechanical parts.

Quantities & timeline

Injection molds for the complex internal locking mechanisms require high precision to ensure smooth operation. Spring calibration is critical to prevent either weak retraction or dangerous snap-back. Testing for connector durability takes significant time. Send us your interface specs, cable length, material preferences, quantity and target price and we will reply with options.
