Adjustable Tie Assembly with Concealed Hardware for Outdoor Structures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional structural connection members are not adjustable and have a utilitarian appearance, which is a concern in outdoor constructions where the hardware is exposed, such as in pergolas and gazebos, and may not match the ornamental design of structures like those with exposed rafters.
Innovation Solution
An adjustable assembly comprising orthogonal plates with flanges and a cover that allows for adjustable force distribution between structural members, enabling concealment of the hardware and accommodating interchangeable accessories, enhancing the aesthetic appeal and functionality of outdoor structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional structural connection members are used, then the connection is structurally functional, but the appearance is utilitarian and not aesthetically pleasing in outdoor constructions
Solution Approach 1:
The connector is divided into separate components: a first plate with first flange, a second plate with second flange, and a cover. This segmentation allows each component to be optimized independently - the plates provide structural function while the cover provides aesthetic appearance, resolving the contradiction between utilitarian function and aesthetic design.
Solution Approach 2:
The cover acts as an intermediary element that conceals the utilitarian plates and flanges from view. This intermediary component allows the structural members to maintain their functional design while presenting an aesthetically pleasing appearance in outdoor constructions, directly resolving the appearance contradiction.
2Reliability
If conventional non-adjustable connectors are used, then the initial structural configuration is fixed, but the forces exerted on structural members change when members settle or shift
Solution Approach 1:
The connector incorporates adjustable elements (such as adjustable flange positions or adjustable fastening mechanisms) that allow the connection to be modified after installation. This dynamic capability enables the connector to adapt to structural settling or shifting, maintaining reliable force distribution throughout the service life of the structure.
Solution Approach 2:
The connector is designed with pre-configured adjustment mechanisms that can be activated when needed. The structure of the plates and flanges is prepared in advance to allow for force adjustments, enabling maintenance of structural reliability without requiring complete disassembly or replacement of the connector.
3Shape
If exposed hardware is used in outdoor constructions, then the structural connection is visible, but it does not match the ornamental design of structures with exposed rafters
Solution Approach 1:
The cover serves as an intermediary aesthetic element that matches the ornamental design of exposed rafters and other architectural features. It conceals the utilitarian hardware while presenting a visually consistent appearance that harmonizes with the overall ornamental design of outdoor constructions.
Solution Approach 2:
The cover is designed with specific aesthetic qualities (such as decorative patterns, finishes, or shapes) that match the local ornamental requirements of the construction. This local quality customization allows the connector to blend with exposed architectural elements while the internal plates maintain their functional design.

AI summary
In an embodiment, an assembly includes a first plate comprising a first primary portion and a first flange disposed orthogonally to the first primary portion. The first primary portion is configured to contact a first structural member and the first flange defining a first through hole. A second plate comprises a second primary portion and a second flange disposed orthogonally to the second primary portion. The second primary portion is configured to contact a second structural member and the second flange defines a second through hole. A cover receives the second flange. A bolt is received through the first through hole, and tightening the bolt draws the first flange toward the second flange.
