Oral care device with improved workpiece connection mechanism
A recently granted patent (Publication Number: US11998668B2) discloses an innovative oral care device featuring a unique connection mechanism between the workpiece and handle assembly. The device includes a collet with axially extending beams and protrusions that engage with the workpiece to prevent withdrawal in one direction and facilitate insertion in the opposite direction. An angled surface on the handle assembly allows for the conversion of axial force into radial deflection of the beams, transitioning the connection mechanism from locked to unlocked configuration. The beams return to their default position after the force is released, thanks to strain energy stored during deflection.
The patent also outlines a method for connecting the workpiece and handle assembly using the described connection mechanism. The process involves inserting the workpiece, engaging the latching surface of the protrusion, exerting axial force on the collet, and utilizing the angled surface to facilitate disengagement of the latching surface. Additional steps include aligning a detent in the workpiece with the protrusion and returning the beam to its default configuration through strain energy. The method highlights the versatility of the connection mechanism, as the radial deflection of the beam occurs regardless of whether axial force is applied directly to the collet, showcasing the efficiency and reliability of the design.
