Switchable Magnetic Coupling for Removable Radiation Shielding

The patent applies the dynamics principle by making the magnetic attachment strength可调 (adjustable). The magnetic attachment device can be configured to provide different levels of magnetic force, allowing it to strongly hold the radiation shielding in place during normal operation yet be easily released when removal is needed. This resolves the contradiction between strong attachment and ease of removal by making the attachment strength dynamic rather than fixed.

The patent applies segmentation by dividing the magnetic attachment function into multiple magnetic attachment devices distributed across the radiation shielding. Instead of using one or two extremely strong magnets, the total magnetic force is distributed across multiple devices. This allows the shielding to be securely held while enabling easier removal, as the force from individual magnets is less concentrated and can be more effectively overcome.

The patent applies local quality by providing a barrier layer between the magnets and the elastomer material in areas where the magnets are embedded. This barrier layer protects the elastomer from degradation caused by proximity to the magnets while allowing the elastomer to maintain its flexibility in other areas. The solution addresses the local degradation issue without compromising the overall flexibility of the radiation shielding.

The patent applies composite materials by combining multiple materials with different properties to create the magnetic attachment device. The device includes a magnetic material (such as ferrite or rare-earth magnets), a barrier layer (such as epoxy or polyester), and optionally a flexible material (such as rubber or silicone). This composite structure provides both strong magnetic attractive force and sufficient resistance to external forces like seismic activity, while also protecting the elastomer from degradation.
