Double Folding Handle Structure for Drop-Resistant Sperm Extractors

The patent applies the dynamics principle by implementing folding handles that can transition between extended and retracted positions. The handles are designed to fold against the housing body, dynamically changing the device's profile from extended to compact. This allows the device to maintain ease of operation when handles are extended while providing protection against falling damage when folded during storage or transport.

The patent employs protective cover structures that can flexibly cover the handles when folded. These protective covers or shells are designed to wrap around or over the folding handles, providing a protective layer that prevents damage during falls or impacts while maintaining the flexibility needed for the folding mechanism to operate smoothly.

The patent applies segmentation by dividing the handle structure into multiple segments or sections that can fold relative to each other. The handles are segmented into sections connected by joints or hinges, allowing each segment to move independently. This segmentation enables the folding function while distributing the mechanical complexity across multiple simple joints rather than requiring a single complex mechanism.

The patent implements the nesting principle by designing the folding handles to collapse or nest against the housing body when folded. The handle segments are arranged to fit within or alongside the housing structure when in the retracted position, maximizing space efficiency and minimizing the overall device footprint while maintaining structural integrity.
