Solar-Powered Umbrella Frame with Integrated Wiring Channels

The problem

Outdoor umbrellas equipped with solar panels and LED lights typically suffer from poor cable management. In many existing designs, the wires connecting the solar cells to the battery and lights are exposed along the outer surface of the ribs or hang loosely under the canopy. These external wires are vulnerable to tangling, abrasion from wind movement, and UV degradation. Furthermore, when the umbrella is opened or closed, exposed cables can get caught in the moving joints, leading to breakage or failure of the electrical system. Aesthetically, visible wiring disrupts the clean lines of modern outdoor furniture. Manufacturers need a structural solution that integrates electrical pathways directly into the mechanical frame, ensuring durability and a tidy appearance without compromising the standard folding mechanism.

The solution

The patent describes an umbrella frame structure that incorporates specific channels for wire routing.

1. The umbrella stand body consists of a central umbrella rod and several umbrella frameworks (ribs) that pivot on the rod.
2. Mounted on this body are solar chips, an energy storage power supply (battery), and light sources.
3. These components are electrically connected by connecting wires.
4. Crucially, the umbrella stand body features a wire cavity arranged along its extension direction. At least part of the connecting wires are placed inside this cavity.
5. The wire cavity can be formed by making the outer wall of the umbrella body surround a circle to create a hollow structure, or by providing a containing groove along the extension direction.
6. Specifically, the first wire cavity extends along the length of the umbrella frameworks (ribs), and the second wire cavity extends along the length of the umbrella rod.

Who it is for

• Outdoor Furniture Brands: Companies looking to offer premium solar-powered patio umbrellas with a cleaner aesthetic than competitors using external wiring.
• Garden Equipment Wholesalers: Distributors seeking durable solar umbrellas where the electrical components are protected from weather and mechanical stress.
• Café and Hospitality Suppliers: Businesses needing reliable lighting solutions for outdoor seating areas that require low maintenance and high visual appeal.
• OEM Manufacturers: Factories producing custom solar tents or umbrellas who need a standardized structural approach to integrating electronics.

How it works

The main parts

The structure relies on modifying standard umbrella components to include space for electronics.

Operating steps

1. Assembly: The solar chips and light units are attached to the umbrella frameworks.
2. Wiring: Connecting wires are routed through the first wire cavity inside the ribs.
3. Central Connection: The wires converge at the upper or lower nest structures and pass into the second wire cavity inside the umbrella rod.
4. Power Management: Inside the rod, the wires connect to the energy storage power supply and potentially a controller.
5. Operation: When deployed, the internal wires remain protected. Sunlight charges the battery via the solar chips; at night, the battery powers the light sources.

Applications

Patio Dining Sets

Used in residential backyards, these umbrellas provide evening ambiance. The hidden wires prevent children or pets from tripping over or chewing on exposed cables, enhancing safety and longevity.

Commercial Café Terraces

Restaurants and cafes use these for outdoor seating. The clean look appeals to customers, and the robust internal wiring withstands the frequent opening and closing cycles required by commercial staff.

Beach and Poolside Lounging

Ideal for poolside areas where humidity and splashing are common. The sealed wire cavities offer better protection against water ingress compared to externally taped wires, reducing corrosion risks.

Camping and Glamping Tents

Adapted for solar tents, this structure allows for built-in lighting and device charging ports. The integrated nature saves weight and space compared to carrying separate power banks and tangled cords.

Where it is less suitable

• Ultra-Lightweight Travel Umbrellas: The addition of metal/plastic cavities and batteries adds weight and bulk, making it unsuitable for backpackers prioritizing minimal gear weight.
• High-Wind Industrial Zones: While the wiring is protected, the overall structural integrity depends on standard umbrella materials; extreme wind loads may still damage the frame if not reinforced separately.
• Low-Cost Disposable Items: The manufacturing complexity of creating hollow ribs and precise internal channels increases cost, making it impractical for cheap, single-use promotional umbrellas.
