Hinged Shield Assembly for Structural Cable Inspection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Structural members in bridges, tunnels, and buildings face challenges in being protected from various threats without hindering inspection processes, as existing protection methods are either permanently affixed or require removal for inspection, which can be cumbersome and disruptive.
Innovation Solution
A protection system featuring a shield assembly with a hinge mechanism and bracket assembly that allows the shield to pivot away from the structural element while remaining attached, enabling easy inspection without the need for removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If protection system is permanently affixed to structural element, then protection reliability is improved, but inspection accessibility deteriorates
Solution Approach 1:
The protection system transitions from a static permanently affixed state to a dynamic removable state through the hinge mechanism and bracket assembly, allowing the shield to pivot between protected and inspected positions, thus simultaneously achieving protection reliability and inspection accessibility
2Ease of operation
If protection system is removed for inspection, then inspection accessibility is improved, but protection reliability deteriorates
Solution Approach 1:
Rather than complete removal, the system uses a dynamic pivoting mechanism that allows the shield to be positioned away from the structural element during inspection while remaining connected through the hinge and bracket assembly, thus maintaining protection reliability while improving inspection accessibility
Solution Approach 2:
The protection system is divided into separable components (shield assembly, bracket assembly, hinge mechanism) that can be independently positioned, allowing the shield to be pivoted away for inspection while remaining functionally connected through the hinge mechanism
3Ease of operation
If protection system requires removal and reattachment, then inspection accessibility is improved, but loss of time increases
Solution Approach 1:
The hinge mechanism enables quick pivoting motion that transitions the shield from protected to inspected position in a single rotational movement, eliminating the time-consuming processes of complete removal and reattachment while maintaining inspection accessibility

AI summary
A protection system for a structural element is provided. The protection system employs a shield assembly comprising two parts formed of one or more materials configured to provide protection from a threat, such as a blast, projectiles, cutting, or a fire. At least one bracket assembly attaches to the structural element. The shield assembly is hingedly attached to the bracket assembly, so that the two parts of the shield assembly can be moved away from the structural element while remaining attached to the structural element.
