[AA] Self-Balancing Landing Mechanism For Multi-Robust Unmanned Aircraft

Decision to accept a valid application: 227231/QĐ-SHTT.IP (03/10/2025). This invention, in the field of mechanical engineering and aerospace, relates to the mechanical structure and landing gear mechanism of multi-rotor unmanned aerial vehicles, specifically an improved landing gear design for self-balancing and shock absorption during landing. The goal of this invention is to propose a landing gear mechanism for multirotor unmanned aerial vehicles (UAVs). Specifically, the landing gear mechanism is capable of automatically adjusting the length of the landing gear using a screw mechanism combined with the UAV's sensor system to determine whether the UAV is balanced. This allows for independent control signals to adjust the landing gear dimensions, ensuring safe landings on rough or uneven terrain.

[AA] The Vertical Take-off and Landing Drone uses Three Engines and Has Retractable Landing Gear

Decision to accept a valid application: 27081/QĐ-SHTT.IP (03/07/2025). This invention relates to the field of unmanned aerial vehicle (UAV) technology, specifically fixed-wing UAVs capable of vertical take-off and landing (VTOL)—utilizing a three-rotor configuration—combined with horizontal flight capabilities. The invention proposes a fixed-wing VTOL UAV that achieves vertical take-off and landing through a tri-copter configuration combined with a controllable tilt-motor mechanism, featuring a retractable landing gear system and a quick-detach modular design. Featuring a a tri-motor configuration featuring an intelligent navigation mechanism and a multifunctional integrated structure, this UAV reduces manufacturing costs and energy consumption while enhancing maneuverability and operational efficiency, making it suitable for various practical applications such as precision agriculture, terrain monitoring, emergency rescue, light cargo transport, and special missions in hard-to-reach areas.

[PP] Automatic Slat Nailing Machine

Patent No. 1-0023006-000, Number of applications: 1-2017-01231, Date of degree issuance: 30/12/2019. In the era of Industry 4.0, enterprises must constantly seek to improve technological processes and implement automation to reduce production costs and enhance competitiveness. The cable manufacturing industry—covering fiber optic, power, and wired communication cables—is no exception to this competitive landscape. The automatic cable reel battening machine was designed to address the task of attaching protective battens to fiber optic and signal cable reels in manufacturing plants, thereby reducing manual labor and increasing productivity.
