Snap-together Standoffs for Structural Repair and Cladding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for repairing, restoring, reinforcing, protecting, and cladding structures are often difficult and time-consuming, especially when access to the structure is constrained due to its design, environment, or materials, and there is a need for efficient solutions that can address degradation from corrosion, harsh environments, and inferior structural integrity.
Innovation Solution
A method and apparatus using elongated standoffs that can be configured from an open to a closed position, allowing for easy mounting and closure to form a standoff connector, which couples cladding panels to the structure, creating a void for introducing curable materials to form a repair structure, while the panels act as formwork until the material cures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional repair methods are used on constrained structures, then structural integrity can be restored, but the repair process becomes difficult and time-consuming
Solution Approach 1:
The repair system is divided into modular components: standoffs that can be independently positioned and secured to the substrate, and cladding panels that can be separately attached. This segmentation allows each component to be installed efficiently without requiring complex integrated operations, significantly reducing overall repair time while maintaining structural integrity.
Solution Approach 2:
The standoffs are pre-positioned and secured to the substrate before the cladding panels are attached. This preliminary action creates a prepared framework that guides subsequent panel installation, eliminating the need for complex real-time adjustments and reducing the overall repair process time.
2Reliability
If access to the structure is constrained by design or environment, then structural integrity can be maintained, but repair operations become difficult
Solution Approach 1:
The standoffs are designed with movable arms that can transition between open and closed configurations. This dynamic capability allows workers to access the substrate surface for standoff installation, then close the arms to secure the panel, accommodating constrained access environments while maintaining structural integrity.
Solution Approach 2:
The standoff arms extend perpendicular to the panel surface, creating a three-dimensional mounting structure. This dimensional approach allows installation and securing operations to occur from directions that are accessible even when direct surface access is constrained, while still achieving reliable structural attachment.
3Ease of manufacture
If cladding panels are directly attached to the structure, then installation is simple, but no void is created for introducing curable materials
Solution Approach 1:
The standoffs serve as intermediary elements between the substrate and the cladding panels. They create and maintain a controlled void space that allows curable materials to be introduced and positioned, while still enabling relatively simple panel attachment through the standoff mechanism.
Solution Approach 2:
The attachment system is segmented into standoffs that create the void space and cladding panels that attach to the standoffs. This segmentation simultaneously achieves installation simplicity through standardized components while providing adaptability by maintaining the material introduction void.
4Reliability
If the structure is reinforced with additional materials, then structural integrity improves, but the repair process becomes more complex
Solution Approach 1:
The standoffs serve multiple functions: they position the cladding panels, create the void space for curable materials, and provide attachment points. This multi-functionality reduces the need for separate components for each operation, simplifying the overall repair system while maintaining enhanced structural integrity through material incorporation.

AI summary
A method covers at least a portion of a surface of an existing structure with a repair structure. The method comprises: providing a standoff, the standoff elongated in a longitudinal direction and operable from an open configuration to a closed configuration; while the standoff is in the open configuration, mounting the standoff to the existing structure, such that the standoff projects outwardly away from the surface of the existing structure; closing the standoff to the closed configuration, the closing of the standoff forming a standoff connector; and coupling a cladding panel to the standoff by engaging the panel with the standoff connector at a location spaced outwardly apart from the surface of the existing structure by a void.
