This invention discloses a vibration-tactile training knee brace device for hearing-impaired dancers. Through the cooperation of an electromagnetic block, a magnetic block, and a traction belt, the movable part of the silicone ring on the knee brace is dynamically expanded. When the hearing-impaired dancer performs a compound movement of kneeling followed by an inward lateral slide, the electromagnetic block is activated, moving the traction belt and causing the movable part to expand outward. This allows the protective area of ​​the silicone ring to expand outward before the knee lateral slides inward, thus actively adhering to and continuously wrapping the inner edge of the knee. This effectively avoids the protection failure problem caused by relative sliding in traditional knee braces during such movements. Furthermore, the cooperation of a small suction cup, a silicone pad, and a thin flexible tube provides stable support for the silicone ring during a single kneeling movement, ensuring stable cushioning performance. When an inward lateral slide is required, the movement of the magnetic block can drive airflow to release the adhesion between the small suction cup and the silicone pad, achieving a switch between static locking and dynamic unlocking of the knee brace.

The TouchDate technique is an innovative approach to personalized jewelry design, integrating both tactile and non-tactile elements to encode significant dates in a way that creates a private and meaningful connection for the wearer. Unlike traditional commemorative jewelry, which often uses visible markers like engravings, birthstones, or other decorative features, TouchDate takes a more discreet and personalized approach by arranging elements—either raised or flat—according to a specific system that corresponds to a chosen date, such as an anniversary or birthday. Tactile components, like raised metal domed dots or diamonds, are carefully placed to represent the month and day of the significant date, allowing the wearer to physically feel the representation of their memory. This tactile interaction creates a sensory connection, offering a subtle yet constant reminder of the personal milestone.
