The problem
Integrating electronic devices like Bluetooth headsets into standard caps often results in poor fit, unstable mounting, or bulky external attachments. Users cannot easily adjust the position of the device to match their ear shape or head size, leading to discomfort during extended wear. Furthermore, traditional caps offer limited protection against glare or wind for the eyes unless separate sunglasses are worn, which may not integrate well with the headset. There is a need for a headwear solution that securely holds electronics, allows positional adjustment without tools, and provides integrated, adjustable eye protection.
The solution
This patent describes a cap body equipped with a specialized mounting frame. Inside this frame, a movable plate carries the Bluetooth headset. The plate slides along internal grooves and is locked in position by insertion rods pushed by springs, allowing the user to adjust the headset’s left-right position manually. The headset itself is clamped between clamping plates secured by a locking nut on a threaded rod. At the lower edge of the cap, an annular shielding plate supports a transparent plastic plate. An inner shielding plate can be adjusted vertically relative to the outer ring using a push block and a fixing rod with an elastic rubber tip, providing customizable eye coverage.

Who it is for
- Consumer electronics accessory brands seeking differentiated headwear that integrates audio devices securely.
- Outdoor activity gear manufacturers needing hands-free communication solutions with added eye protection features.
- Industrial safety suppliers looking for hard hat liners or cap accessories that accommodate radio headsets.
- OEM/ODM partners producing custom-branded smart apparel with modular component designs.

What the claims cover, in plain language
Claim 1 defines a cap comprising a cap body, a Bluetooth headset, a mounting frame fixed to the body, and a locking mechanism. The frame contains a baffle and a movable plate. The movable plate has a containing groove with an intermediate block connected by springs to push plates. These push plates have insertion rods that engage the frame walls to lock the plate’s position. The locking mechanism uses a threaded rod with U-shaped plates and a locking nut to clamp the headset between clamping plates. The claim also details an annular shielding plate at the cap’s lower end, holding a transparent plastic plate and an adjustable shielding plate secured by a fixing mechanism.
Claims 2-7 add specific features: magic tape (hook and loop) for attaching the baffle, sliding rails (grooves and sliders) for the movable plate, insertion holes in the frame, and details of the fixing mechanism involving a fixing rod, push block, and elastic rubber block for adjusting the shielding plate. Claim 7 outlines the usage method.
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 in China and is currently in force. The public record shows no US or other foreign counterpart. Therefore, making or selling this specific design in China requires the owner’s permission. For the US market, the absence of a US patent means this specific technical disclosure does not restrict manufacturing or sales in the United States.
Two points to settle early:
- Other patents may exist. Wearable technology and headwear integration are competitive fields. While this specific mechanical arrangement appears unique to the Chinese filing, a freedom-to-operate (FTO) review is recommended to check for broader US patents covering Bluetooth-integrated caps or adjustable visor mechanisms.
- Component Compatibility. The design relies on standard Bluetooth headsets fitting the clamping mechanism. Ensuring compatibility with common consumer headset sizes is critical for market acceptance.
Customization and manufacturing
What can be customized
| Area | Options |
|---|---|
| Cap Material | Cotton, polyester, nylon, or blended fabrics depending on target activity |
| Frame Color/Finish | Injection-molded plastics can be color-matched to brand identity |
| Shield Type | Clear, smoked, or polarized transparent plastic inserts |
| Headset Fit | Dimensions of the clamping plates can be adjusted for different headset models |
| Branding | Embroidery or heat-transfer logos on the cap body |
Things to plan for (US market)
- FCC Part 15: If the cap includes its own Bluetooth module (not just a mount), it must comply with FCC regulations for unintentional radiators. If it only mounts third-party devices, the device itself handles compliance.
- California Prop 65: Plastics and dyes used in the frame and fabric must be screened for listed chemicals.
- CPSC Safety Standards: General safety requirements for children’s products if marketed to minors (e.g., small parts, flammability).
- ASTM F963: If sold as a toy or for children under 12, relevant safety standards apply.
How a project runs
- Inquiry - Define target demographic, material preferences, and quantity.
- Design Adaptation - Modify frame dimensions to fit specific headset models; select shield optics.
- Prototype - Create 3D-printed frames and sewn cap samples for fit testing.
- Pilot Run - Test durability of spring mechanisms and clarity of shields.
- Production - Injection molding for frames, sewing for cap bodies, assembly of hardware.
Quantities & timeline
Tooling for the injection-molded mounting frame and fixing components will dictate initial costs. Fabric cutting and sewing lines are standard. Lead times depend on mold fabrication and fabric sourcing. Send us your target materials, headset specifications, and volume estimates and we will reply with options.
Production notes
Tooling and process
Injection molding is likely required for the complex geometry of the mounting frame and movable plate. TPU or ABS plastics are typical choices for these structural components. Sewing and adhesive bonding will attach the frame to the cap body.
Cost drivers
The primary cost drivers are typically the steel tooling for the injection molds and the grade of fabric selected. Stitch density affects labor time, while the number of sizes impacts pattern grading complexity. Packaging design also contributes to unit cost.
Prototyping path
Prototyping typically starts with a sewn first sample using 3D-printed frame components to verify fit and function. Conduct a wear trial to test the spring-loaded adjustment mechanism. Proceed to fit grading across standard head sizes before finalizing production patterns.
What we would change before tooling
We might simplify the insertion rod engagement to reduce mold complexity. Testing alternative elastic materials for the rubber block could improve longevity. Reviewing the thread pitch on the locking nut ensures easier manual operation.
Common failure points
Seam slippage where the heavy frame attaches to the light fabric is a risk. Spring fatigue could lead to loose adjustments over time. Hardware corrosion may occur if metal threads are exposed to sweat. Wire routing issues might arise if users modify the setup.

Frequently asked questions
Which Bluetooth headsets fit this cap?
The patent describes a generic clamping mechanism using a threaded rod and plates. It is designed to hold standard ear-cup style Bluetooth headsets. Specific compatibility depends on the dimensions of the containing groove and clamping plates, which can be customized in production to match popular headset models.
How do I adjust the headset position?
You press the push plates located on the sides of the mounting frame. This retracts the insertion rods from the frame walls, allowing the movable plate (which holds the headset) to slide left or right. When you release the push plates, springs automatically drive the rods back into place to lock the new position.
Is the visor removable?
The patent describes an inner shielding plate that slides within an outer transparent plastic plate. It is adjustable vertically but appears to be part of the integrated annular shielding structure rather than a fully detachable standalone lens. The entire assembly is fixed to the cap’s lower edge.
Does the cap have its own battery?
No. The patent focuses on the mechanical mounting and adjustment structure. It holds a Bluetooth headset but does not describe an internal battery, charging port, or electronic circuitry within the cap itself. You supply the headset.
Can I use it with prescription glasses?
The transparent plastic plate acts as a shield. Since the headset sits above the ears and the shield covers the face, users who wear glasses should try the prototype to ensure the temple arms of their glasses do not interfere with the headset clamps or the shield mechanism.
Is the material waterproof?
The patent mentions “transparent plastic” for the shield and various materials for the cap body. It does not specify waterproof ratings. Standard cap fabrics vary; production can select water-resistant materials if required for outdoor use.
Can this design be made and sold in the US?
The patent is in force in China, but the public record shows no US counterpart. This means the specific mechanical design described here does not restrict manufacturing or sales in the United States. However, we recommend a freedom-to-operate check to ensure no other broad US patents cover similar wearable tech integrations.
Are you affiliated with the patent owner?
No. IP2M is an independent design and manufacturing service working from the public patent document.
