Captive Shear Bolt Assembly for Retaining Sheared Bolt Heads

The patent applies the nesting principle by placing the sheared portion of the bolt inside a retaining structure (such as a hollow bolt body or retaining cavity) that captures and holds the sheared segment. The bolt shaft is nested within a retaining structure that prevents the sheared portion from falling, while still allowing the bolt to function as intended. This resolves the contradiction by maintaining the torque limitation function while eliminating the safety hazard of falling debris.

The patent introduces an intermediary component (retaining structure, hollow bolt body, or capture mechanism) that mediates between the shearing action and the potential harm. This intermediary structure captures the sheared portion and prevents it from falling to the ground, while allowing the bolt to perform its torque limitation function. The intermediary element resolves the contradiction by decoupling the shearing function from the harmful effect.

The patent merges the retention function with the existing bolt structure by integrating the retaining structure as part of the bolt itself (such as a hollow bolt body that contains the sheared portion). This merging approach combines multiple functions (torque limitation and debris containment) into a single integrated component, reducing the need for separate retaining mechanisms and minimizing overall device complexity while improving safety.

The patent makes the bolt multi-functional by designing it to simultaneously perform torque limitation and retain the sheared portion. The hollow bolt body or integrated retaining structure serves dual purposes: it allows the bolt to shear at the designated point for torque control while also capturing and holding the sheared segment. This multi-functionality resolves the contradiction by adding safety functionality without requiring separate dedicated retaining components.
