AI Technical Summary
Traditional two-section badminton shuttlecocks require two coils to be wound and then cured with glue, resulting in a complicated production process, high costs, and coil fatigue and softening that cannot withstand repeated hits, and are difficult to replace.
The connector uses an injection-molded one-piece frame, which connects to the feather shaft of the natural feather through the insertion tube. The coil is eliminated. The design of reinforcing ribs and circular thin plates ensures that the feather shaft is thick enough to withstand the impact force, and the connection is fixed with glue.
It simplifies the production process, reduces costs, improves the durability and replaceability of shuttlecocks, reduces the weight of coils and glue, and enhances the structural consistency and flight stability of shuttlecocks.

Abstract
Claims
1. A shuttlecock without a coil, comprising a natural feather piece, a connecting frame and a head, characterized in that, The connecting frame is injection molded as a single unit. It includes a circular thin plate, a cylindrical barrel, and multiple feather insertion tubes. Each feather insertion tube is evenly arranged on the circumference of one side of the circular thin plate, with each tube forming an angle with the central axis of the plate. On the other side of the circular thin plate, a cylindrical barrel coaxial with the plate has a circular groove coaxial with the barrel. The size of the cylindrical barrel matches the size of the circular groove, and the barrel is inserted into the groove and securely connected. The root width of the natural feather shaft is 3.5~6mm, and the shaft is inserted into the feather insertion tube and securely connected. A second reinforcing rib connects the feather insertion tube and the circular thin plate. This second reinforcing rib has a conical structure, and its overall structure gradually decreases in size from the feather insertion tube to the axis of the circular thin plate. The circular thin plate has a first central hole extending through its axis, and the ball head has a second central hole extending through its axis, which communicates with the first central hole; a spring piece is placed inside the first central hole of the circular thin plate; and a whistle is installed inside the second central hole of the ball head.
2. The shuttlecock according to claim 1, characterised in that The angle between any of the inserted tubes and the central axis of the circular thin plate is 15° to 30°.
3. The shuttlecock according to claim 1, wherein The natural feather is made by cutting off the remaining feather root, which is the structure left after cutting off a natural feather from a natural shuttlecock.
4. The shuttlecock according to claim 1, wherein A first reinforcing rib connects two adjacent insertion tubes of the connecting frame.
5. The coil-free shuttlecock according to claim 1, wherein The number of the insert tubes in the connecting frame is 4 to 12.
6. The shuttlecock according to claim 1, wherein The length of the natural feather is 40–65 mm.
