Pivotable Tie-Down Wrap Device for Heavy Loads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing load-retaining devices are not adaptable to a wide variety of articles, such as metal tubing, vehicles, and have limited pivotability and durability issues due to specific anchor point requirements and fouling of hook-and-loop couplings, leading to insecure connections under changing loads.
Innovation Solution
A tie-down/anchor point wrap device with pivotable, easily changeable hardware attachment points and a backup securement loop, made of 100% polyester with stainless steel components, designed for heavy loads and compatible with various securing mediums, allowing for secure wrapping around different anchor points without tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the connector hardware is securely fixed in an orthogonal orientation to the wrap device, then the connection stability is improved, but the pivotability and adaptability to changing load conditions deteriorates
Solution Approach 1:
The connector hardware is designed to be pivotable rather than fixed, allowing it to dynamically adjust its orientation in response to changing load conditions. The connector can rotate within a defined range while maintaining secure attachment, enabling adaptation to various loading scenarios without requiring multiple fixed-orientation connectors.
2Manufacturing precision
If the connector hardware is installed in a specific orientation with limited opening size, then the manufacturing precision is improved, but the ease of operation and replacement deteriorates
Solution Approach 1:
The connector assembly is segmented into separable components that can be independently manipulated. The connector hardware can be detached and reattached to the wrap device without requiring complete disassembly, allowing for easy replacement while maintaining precise alignment through the use of alignment features and flexible positioning.
3Ease of operation
If the hook-and-loop coupling is used to secure the wrapping position, then the ease of operation is improved, but the reliability deteriorates due to fouling with foreign materials over time
Solution Approach 1:
A backup retention mechanism is incorporated into the wrap device design that provides redundant security against coupling failure. This backup system is pre-configured to engage if the primary hook-and-loop coupling becomes fouled or fails, ensuring continuous load retention without requiring manual intervention.
4Manufacturing precision
If the wrap device is designed for a specific anchor point size, then the manufacturing precision is improved, but the adaptability to different applications deteriorates
Solution Approach 1:
The wrap device is designed with universal compatibility features that allow it to function with various anchor point sizes and configurations. The connector hardware and wrapping mechanism can accommodate different anchor geometries through adjustable positioning and flexible engagement, enabling a single device design to serve multiple applications without sacrificing fit precision.

AI summary
The inventive disclosure is generally directed to an improved tie-down/anchor-point/attachment-point wrap device that can be used for heavy loads and/or shipping of articles in conjunction with various securing mediums such as a bungee cords, tie-down straps, ropes, etc. Each device features an easily changeable, yet securely coupled and pivotable, hardware-attachment point; two parallel strips of heavy-duty webbing for load-bearing that is reinforced with a plurality of high-surface-friction (that is, “gripping”) substrates stitched to the webbing; and reinforcing substrates that include the mating surfaces for a hook-and-loop coupling to secure the device in place when wrapped-around a structural member, with a longitudinal space disposed between the strips of webbing and reinforcing substrates to allow a pivotable connector to extend through when installed on a structural member, and a backup securement loop for the hardware-attachment point.
