Abstract

The present invention provides a system equipped with a self-healing function and a modular multi-layer structure to maximize shockwave absorption performance. This structure, composed of a mesh-shaped material, a carbon layer, and an adhesive, absorbs and disperses the energy of shockwaves while simultaneously converting it into heat, thereby reducing side effects during the treatment process. In particular, since each layer is modularized, it can be replaced and adjusted as needed. Furthermore, through its self-healing function, it can repair itself even if damage or cracks occur due to shockwaves, thereby providing a system that maintains stable performance over the long term. Additionally, by dispersing shockwaves over a wide area to prevent concentration on specific sites, the invention enhances the durability of the equipment and prevents unnecessary damage to surrounding tissues. It also aims to provide a system that can be widely applied in industrial and medical fields by offering consistent performance across various frequency bands without the need for thickness adjustment.

Description

Shock Wave Absorption and Dispersion System Using Self-Healing and Modularized Multilayer Structure The present invention relates to a system that improves shock wave absorption performance through a self-restoring and modularized multilayer structure. Specifically, the invention aims to provide a system that maximizes energy absorption by absorbing and dispersing rapid energy release through a structure combining a mesh-shaped material, an adhesive, and a carbon layer, and which allows each layer to be modularized so that it can be replaced and adjusted as needed, and which can maintain long-term performance through a self-restoring function. [Project No.] RS-2023-00219593 [Ministry Name] Ministry of Science and ICT (P71) [Name of Project Management (Specialized) Agency] National Research Foundation of Korea [Research Project Name] Support for Diffusion of Talent Utilization (162111015015417001744412) [Project Title] Development of Innovative Manufacturing Technology for Energy-Storage Materials through Shockwave Flow Control [Contribution Rate] 1/1 [Name of Project Performing Organization] Keimyung University Industry-Academic Cooperation Foundation [Research Period] 2024-01-01~2024-12-31 [Purpose] Submitted to the Commissioner of the Korean Intellectual Property Office as stated above. Existing shockwave absorption technologies have limitations in that they fail to sufficiently satisfy the absorption and dispersion performance requirements of various environments, thereby compromising the reliability of treatment and protective equipment. Conventional shockwave therapy equipment used in the medical field has limitations in accurately delivering shockwaves to specific areas. Consequently, shockwaves may be transmitted to surrounding tissues outside the treatment site, potentially causing unnecessary damage or pain. As shockwaves spread beyond the treatment area, unexpected side effects occur, which compromise patient safety and reduce treatment effectiveness. If shockwaves are delivered to sensitive tissues or weak areas of the body, the risk of damage increases, and pain during treatment may intensify, causing discomfort for both medical staff and patients. To address these issues, advanced shockwave absorption technology is required that can deliver shockwaves locally only to the desired area while protecting other parts of the body. Furthermore, there is a significant risk of structural damage to equipment caused by shock waves generated in industrial sites. Shock waves generated during the operation of high-speed machinery or the processing of high-pressure gases carry very high energy; concentrating these waves on specific areas increases the likelihood of equipment damage or failure. Conventional protective equipment is unable to disperse shock waves over a wide area, which can threaten the structural stability of the equipment as the impact concentrates on specific parts. In particular, it is difficult to guarantee equipment durability in environments where high-intensity shock waves occur repeatedly; consequently, efficient protective equipment is required in industrial sites to prevent damage caused by shock waves. Such shock wave absorption devices typically compensate for performance by being composed of multiple layers or designed with a thick structure. However, this design approach increases the weight and volume of the equipment, leading to difficulties in installation and maintenance and reduced work efficiency. The increased weight can make handling difficult in industrial settings, and the larger size of the equipment may result in additional costs and time during transportation and installation. Therefore, there is a need for technology that can effectively absorb shock waves without increasing the weight or volume of the equipment. In addition, the difficulty in maintaining consistent shock wave absorption performance across various environments and frequency bands is also pointed out as a problem. Many existing shock wave absorption devices are designed to perform optimally only at specific frequencies or conditions, making it difficult to respond to frequency changes and potentially leading to performance degradation in different working environments. This issue can act as a factor that reduces equipment stability in industrial sites that must adapt to diverse working conditions, and consequently poses a risk of reduced equipment reliability and service life.
