Details of the Patent
The proposed Omni-directional resonator model presents a promising solution, effectively absorbing vibrations across a broad frequency spectrum and from multiple directions concurrently. Through the strategic use of anti-resonance, transmittance experiences a marked decrease when subjected to harmonic excitation near the resonant frequency of the embedded resonator. Employing 3D printing technology for monolithic model creation has notably reduced the number of joints in structures, mitigating geometrical uncertainties inherent in physical modeling. This innovative approach holds potential for robust vibration control and demonstrates advancements in both resonance manipulation and fabrication techniques.

Details of the Patent
The patent introduces an origami-inspired Self-Lockable Foldable Truss (SLFT) module for robust, portable foldable truss towers in various earth-based applications. Unlike existing structures, this design achieves high strength-to-weight ratios and an efficient folding ratio through origami principles and self-locking mechanisms. The innovation lies in a novel combination of regular and hybrid truss members, enabling bistable behavior: easy folding-deployment and self-locking under compression for stability. Tuned geometric parameters can be optimize for superior performance, ideal for military applications, communication, or wind turbine towers, enhancing load-bearing capacity without compromising portability. The SLFT module revolutionizes deployable structures, offering unparalleled adaptability and strength.

Details of the Patent
The current invention introduces a novel Rigid Elastic Vibration Isolator (REVI) model utilizing 3D printing. This monolithic design, without any mechanical connections, significantly diminishes geometric uncertainties in physical modeling, enhancing its resilience to vibrations. The REVI exhibits a lower-frequency stop band compared to classical spring-mass resonators, attributed to the antiresonance phenomenon. Furthermore, customization of elastic beam and rigid mass properties enables tailoring the stop band as needed. This adaptable REVI system finds practical applications in fields like automotive and machine foundations, especially in scenarios demanding restricted vibration transmission.
