Shockproof Nut Kit With Elliptic Clearance Fit Against Loosening

The patent employs asymmetric elliptical contact surfaces on the nut's end face instead of symmetric circular surfaces. The elliptical shape creates a specific contact area that transmits shock loads while minimizing lateral forces on the threads. The asymmetry in the contact surface geometry allows the nut to withstand shockproof requirements without compromising thread integrity through improper force distribution

The patent applies local quality by creating a specific elliptical contact area on the end face of the nut. This localized contact region is designed to handle shock loads specifically, while other parts of the nut maintain standard threading characteristics. The elliptical contact surface concentrates the shockproof function in a specific location without affecting the overall thread engagement quality

The patent extracts the shockproof function from complex internal structures (grooves and embedded components) and implements it through a simpler external geometric feature - the elliptical contact surface on the nut's end face. This extraction eliminates the need for additional internal components while maintaining the shockproof capability through optimized force transmission geometry

Instead of adding complex internal structures to achieve shockproof effect, the patent inverts the approach by using a simplified external geometric feature (elliptical contact surface). The solution moves from adding complexity internally to achieving the function through external geometry, thereby reducing overall device complexity
