Rotating Bracket Assembly for Flexible Building-Frame Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
On-site frame construction is prone to human error and requires extensive demolition, exposing structures to elements, which can cause damage and increase project time, especially when adding roofs to existing structures.
Innovation Solution
A rotating bracket assembly comprising two nested components that can rotate 360°, allowing for flexible alignment and attachment of structural members without fixed fasteners, enabling off-site assembly and reduced on-site demolition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If on-site construction is performed with fixed fastening methods, then structural stability is improved, but human error increases and construction time extends
Solution Approach 1:
The bracket assembly is pre-engineered and pre-assembled in a controlled factory environment before being transported to the construction site. This preliminary action allows for precise manufacturing and quality control to be completed beforehand, reducing on-site construction time and minimizing human error during assembly.
Solution Approach 2:
The bracket assembly is divided into separable components (first member with first channel, second member with second channel) that can be independently manufactured and then quickly assembled on-site using the rotating connection mechanism, facilitating rapid construction while maintaining structural integrity.
2Manufacturing precision
If manufactured framing assemblies are produced off-site, then construction precision is improved, but assembly size increases and requires extensive demolition
Solution Approach 1:
The first member is nested within the second member, with the first channel positioned inside the second channel. This nesting arrangement allows the bracket assembly to occupy minimal space during transport and storage, reducing the volume requirement while maintaining the precision-engineered components.
Solution Approach 2:
The rotating connection between the first and second members provides dynamic adjustability, allowing the bracket to adapt to different angular positions and alignment requirements on-site. This dynamic capability eliminates the need for extensive demolition and reconfiguration, as the bracket can be adjusted to fit various structural configurations.
3Ease of operation
If extensive demolition is performed to add roofs to existing structures, then structural access is improved, but exposure to elements increases and damage risk rises
Solution Approach 1:
The bracket assembly provides localized access to existing roof structures by targeting specific attachment points. Instead of requiring extensive demolition of the entire roof structure, the bracket enables precise, localized connection to existing trusses or beams, minimizing the area exposed to elements and reducing the risk of damage to surrounding structures.
4Stability of the object's composition
If fixed fastening methods are used, then structural rigidity is improved, but adaptability to different configurations decreases
Solution Approach 1:
The rotating connection mechanism allows the bracket assembly to be adjusted to various angular positions and orientations while maintaining secure fastening. This dynamic capability provides structural rigidity in the installed position while offering adaptability during installation to accommodate different roof configurations, angles, and existing structure geometries.

AI summary
A rotating bracket assembly comprises first and second members, each of which defines a channel having opposing sides coupled to a common base. The first member is nested within the second member with adjacent opposing sides being hingedly coupled to one another so that the first member can freely rotate 360° relative to the second member to achieve a plurality of rotational positions. A first plurality of holes formed in the opposing sides of the first member at least partially align with a second plurality of holes formed in the opposing sides of the second member for each of the rotational positions.
