Rotatable Anchoring Assembly for Self-Aligning Load Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hoist ring assemblies are complex to install, time-consuming, and dependent on pivot pins for load-bearing strength, which limits their structural integrity and flexibility.
Innovation Solution
An anchoring assembly with a rotatable eyelet around a stud's longitudinal axis, featuring a nut and pivot pin system that allows the eyelet to self-align with applied forces, distributing load across the stud and base member, and is designed for easy installation without requiring skilled workers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional hoist ring assemblies use pivot pins and bushings for load bearing, then structural integrity is maintained, but device complexity increases and installation time increases
Solution Approach 1:
The patent combines the pivot pin, bushing, and locking mechanism into a single integrated pivot assembly that rotates within the eyelet. This merging of multiple components into one unified structure reduces the total number of parts while maintaining the load-bearing function through the study of force distribution across the integrated components.
Solution Approach 2:
The patent segments the hoist ring into distinct functional modules: the eyelet for force application, the stud for anchorage, and the integrated pivot assembly for rotation and locking. This segmentation allows each module to be optimized independently while simplifying the overall assembly process and reducing the number of small separate parts.
2Strength
If traditional hoist ring assemblies use multiple separate parts including pivot pins and bushings, then load bearing strength is achieved, but installation becomes time-consuming
Solution Approach 1:
The integrated pivot assembly is pre-configured with the pivot pin, bushing, and locking mechanism as a single unit before installation. This preliminary integration eliminates the need for on-site assembly of multiple small parts, significantly reducing installation time while maintaining the structural integrity required for load-bearing applications.
3Strength
If the eyelet is fixed to the screw upon installation, then structural integrity is improved, but flexibility and adaptability are reduced
Solution Approach 1:
The patent implements a dynamic locking mechanism where the pivot assembly can rotate freely within the eyelet during installation and operation, then be locked in place when needed. This dynamic system provides both flexibility for alignment adjustments and adaptability for different loading conditions, while maintaining structural integrity through the optional locking function.
4Adaptability or versatility
If the eyelet is made separable from the screw, then flexibility increases, but load bearing strength decreases
Solution Approach 1:
The integrated pivot assembly creates a dynamic connection between the eyelet and stud that allows for easy assembly and disassembly while maintaining full load-bearing capacity when engaged. The single-piece design ensures that the connection strength equals the strength of the individual components, eliminating weak points associated with multiple separate fastening elements.

AI summary
The present disclosure describes an anchoring assembly implementable for lifting weight and also anchor point for height access or fall-protection. The disclosed assembly generally comprises a stud with an external elongate surface carrying a screw thread, and a through tunnel fabricated on the stud intersecting and perpendicular to the longitudinal axis of the stud; a construct comprising an eyelet enclosing an opening and a pair of holder members extending out from the eyelet, each of the holder members defining an aperture at its center axis and the defined aperture being of a diameter 0.1 to 2mm greater than the diameter of the stud, the holder members being axially aligned with a cavity of a predetermined length spacing each other for receiving the stud through the apertures; a nut having a sidewall defining an internally threaded passage, the nut being securable onto the stud through the screw thread and resided within the cavity to interpose between the paired holder members, the nut carrying a pair of axially aligned and radially extending through holes on the sidewall, the through holes being adjustable to align with the through tunnel forming a continuous passage thereof; and a pivot pin fillable into the passage across the through holes and the through tunnel to lock the nut to the stud. The eyelet of the disclosed assembly is configured to be rotatable around the longitudinal axis of the stud and the locked nut impedes the construct to move along longitudinal axis of the stud.
