77: Koinobori(carp streamer) with Rotatable Fins | Patent Drawing

Overview of the Patent Drawing

The illustration depicts a koinobori (carp streamer) equipped with rotatable fins (2). The carp-shaped decoration features multiple fish mounted along a central pole (5), with each fish designed to spin or rotate around the pole when exposed to wind. The fins (2) are attached to the body in a manner that allows them to rotate freely, enhancing the motion effect. At the top, a decorative element adds to the visual appeal of the entire structure.

Patent Insight 1: Enhanced Motion with Rotatable Fins

The inclusion of rotatable fins (2) allows the koinobori to exhibit more dynamic movement in the wind compared to traditional carp streamers. As the wind blows, the fins catch the air, causing the fish to spin around the central pole (5). This design not only adds visual interest but also simulates a more lifelike swimming motion, making the display more captivating.

Patent Insight 2: Symbolism and Cultural Significance of Koinobori

Koinobori are traditionally displayed in Japan during Children’s Day to celebrate the strength and determination of children, with the carp symbolizing perseverance and resilience. The addition of rotatable fins enhances the symbolism by making the carp appear more animated, reinforcing the cultural message of vitality and the pursuit of growth.

Patent Insight 3: Practical Design for Outdoor Use

The rotatable fins and sturdy central pole (5) suggest that the koinobori is designed for outdoor conditions. The mechanism allows for smooth rotation even in varying wind speeds, ensuring continuous movement without the risk of tangling or damage. This makes the decoration suitable for gardens, parks, or public displays during traditional festivals.

Thoughts on the Patent Drawing

Upon reviewing the patent drawing for the “Koinobori (Carp Streamer) with Rotatable Fins,” I am impressed by the innovative enhancement to the traditional koinobori. The rotating fins catch the wind, creating a dynamic movement that mimics a real carp swimming, which is visually captivating. This design can intrigue children and foster a deeper appreciation for cultural traditions. Additionally, the varying movements influenced by wind strength and direction provide a sense of harmony with nature. This koinobori, seamlessly blending tradition with innovation, exemplifies Japan’s aesthetic sensibility and technological prowess.

Application of the Technology: “Self-Spinning Koi Drone Delivery Confetti Bomber”

Purpose

By repurposing the rotatable fin technology of the koi streamer, develop a “Self-Spinning Koi Drone Delivery Confetti Bomber”—a festive, air-deployed koi unit that twirls through the sky, delivering confetti payloads, party messages, or surprise gifts mid-flight. It’s the perfect blend of Japanese tradition, aviation chaos、and party magic.

System Components

• Koi-Shaped Drone Shell: An aerodynamic body shaped like a traditional koinobori, made from lightweight carbon-reinforced silk with ridiculous elegance.
• Motor-Driven Rotatable Fins: Instead of passive wind rotation, the fins actively spin via brushless motors, giving the drone an unmistakably koi-like swimming motion midair.
• Confetti Payload Compartment: A belly hatch that stores biodegradable confetti, fortune slips, or glitter bombs—released in dramatic slow-mo on cue.
• Voice Module: Upon activation, the drone plays traditional festival music or shouts encouraging phrases like「がんばれーッ！！！(“You can do it!!!”)」as it circles above.
• Surprise Delivery Hook: An optional micro-hook drops off small presents (like candy, omamori, or apology letters from your boss) via parachute.
• Safety Override Fin-Flare: In case of emergency or wind turbulence, the fins flare out and auto-rotate to descend like a koi-shaped maple seed.

Operational Flow

1. Pre-Flight Ritual: User scans a QR code to upload a message and choose between “confetti strike” or “mystery drop” mode.
2. Takeoff & Activation: The koi drone launches, fins begin spinning wildly, music plays, and the koi does gentle barrel rolls in the sky.
3. Payload Release: At a designated GPS coordinate or timed cue, the confetti payload erupts from the koi’s belly in dazzling rainbow rain.
4. Return to Base (or Dive Dramatically into a Bush): Depending on battery level and AI mood, the koi either returns safely or pretends to dramatically crash-land for added flair.
5. Post-Mission Haiku: The drone displays a random haiku on its LED screen before powering down, because… why not?

This is not just a drone—it’s airborne absurdity with fins. Tradition-meets-technology-meets-confetti. Because nothing says “I care” like a spinning koi dropping glitter from 60 meters up.
