Racket Shock Wave Absorbing Device for Frame Durability

The patent embeds shock absorption devices (first and second shock absorption devices) within the racket frame structure itself. The devices are positioned at specific locations on the frame to intercept and manage shock waves generated during ball impact, allowing the shock absorption function to be integrated into the existing racket structure without requiring a complete structural overhaul.

The patent introduces shock absorption devices as intermediary elements between the string bed and the racket frame. These devices act as mediators that capture and redirect shock waves, preventing them from directly transferring to the frame and causing deformation or breakage. The devices include components such as nodes, strings, and damping elements that work together to manage the shock wave energy.

The patent implements preliminary anti-action by positioning shock absorption devices to intercept shock waves before they reach the racket frame. The devices are strategically placed at locations where shock waves naturally propagate, allowing them to counteract the harmful effects of the shock waves in advance. This includes using damping elements and reflective surfaces to redirect shock wave energy away from critical frame areas.

The patent converts the harmful shock wave energy into beneficial effects by using the shock waves to activate damping mechanisms and energy absorption features within the shock absorption devices. The shock wave energy is transformed into controlled vibrations or heat through damping materials, rather than allowing it to cause frame damage. This includes using the impact energy to compress spring elements or activate viscoelastic dampers.

The patent implements periodic action by creating multiple shock wave reflections and interactions within the shock absorption devices. The devices are designed to generate a series of reflected shock waves that return to the string bed at regular intervals, creating a periodic force application. This includes using reflective surfaces and elastic elements to bounce shock waves back and forth, generating multiple impact cycles that maintain high frequency and cumulative striking force.

The patent utilizes mechanical vibration by designing shock absorption devices that convert shock wave energy into controlled vibrational motion. The devices include elastic elements, springs, and damping components that oscillate in response to shock wave input, generating high-frequency vibrations that are transferred back to the ball member. This vibrational action increases the effective striking frequency while maintaining sufficient energy transfer.
