Have you ever wondered what intricate biomechanics lies behind a simple wave? The human skeleton and joints are like nature's most ingenious connectors, allowing us to walk, run, and write smoothly. Six major joint types each have their specific functions: ball-and-socket joints enable multi-directional rotation of the arm (such as the shoulder joint), elliptic joints allow flexible wrist flexion, flexor joints allow the knee to open and close in only one direction, saddle joints provide the thumb's opposition function, planar joints enable micro-gliding (such as the facet joints of the spine), and axle joints support the left and right rotation of the head. These joints achieve a perfect balance between stability and flexibility through different structural designs. Our "Joint Exploration" interactive exhibit (1950*2060*3500mm) transforms these abstract biomechanical principles into a tangible cognitive experience. The installation includes six joint models, each containing real anat
