Sliding Rotating Bathing Chair for Easier Horizontal Transfer

The patent applies the dynamics principle by transforming the static bathing chair into a dynamic system with movable components. The seat plate is made movable relative to the leg tube assembly through the translation mechanism, allowing the chair to adapt its position dynamically. This enables people with limited mobility to easily move the seat plate horizontally without manually relocating the entire chair, thus improving ease of operation while managing device complexity through targeted mobility.

The patent applies segmentation by dividing the bathing chair into distinct functional modules: the leg tube assembly, the movable transverse tube, and the seat plate with fixed frame. This segmentation allows the transverse tube mechanism to be independently designed and optimized, reducing overall device complexity while enabling the seat plate translation function. The modular structure makes it easier to manufacture, assemble, and maintain each component separately.

The patent applies self-service through the automatic locking mechanism that utilizes the user's own sliding action to engage the lock. When the seat plate is slid to the desired position, the locking mechanism automatically secures it without requiring separate manual locking operations. This design improves reliability by ensuring the seat plate remains stable during use while maintaining ease of operation, as the locking function is integrated into the sliding motion itself.
