Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hoist rings do not allow for easy orientation of a workpiece when suspended by a crane, limiting the ability to maintain specific orientations during lifting.
Innovation Solution
A locking side pull hoist ring assembly that includes a load-bearing structure, a rotation mechanism, and a locking mechanism, allowing the workpiece to be rotated and locked at desired orientations, with a support member connecting these components to enable rotation about defined axes and secure the workpiece in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional hoist rings are used to suspend a workpiece, then the workpiece can be lifted by a crane, but the workpiece cannot be easily oriented or maintained at a specific orientation
Solution Approach 1:
The hoist ring assembly incorporates a rotation mechanism that allows the workpiece to be dynamically rotated about a rotation axis during suspension. This dynamic capability enables operators to adjust and maintain desired orientations of the workpiece, transforming a static suspension system into an adaptable one that can respond to orientation requirements.
Solution Approach 2:
The assembly is divided into distinct functional components: a load bearing structure for suspension, a rotation mechanism for orientation adjustment, and a locking mechanism for securing positions. This segmentation allows each component to perform its specific function independently, enabling both easy rotation and stable orientation maintenance.
2Adaptability or versatility
If a rotation mechanism is added to allow workpiece orientation, then orientation control is improved, but the device complexity increases
Solution Approach 1:
The rotation mechanism and locking mechanism are integrated into a unified assembly that combines multiple functions. The locking mechanism works in conjunction with the rotation mechanism to provide both rotation capability and position securing, reducing the need for separate independent systems and thereby managing complexity.
Solution Approach 2:
The support member serves multiple functions: it connects the load bearing structure to the rotation mechanism, provides structural support, and facilitates the rotation motion. This multi-functionality reduces the number of separate components needed, thereby controlling overall assembly complexity while maintaining orientation control capability.
3Stability of the object's composition
If a locking mechanism is added to secure the workpiece at desired orientations, then orientation stability is improved, but the device complexity increases
Solution Approach 1:
The locking mechanism is designed to maintain the workpiece at the desired orientation without requiring continuous external intervention. Once the workpiece is rotated to the desired position, the locking mechanism automatically secures it, providing self-servicing stability that prevents unintended rotation while maintaining simplicity.
4Adaptability or versatility
If multiple mechanisms (rotation and locking) are added to the hoist ring, then functionality is improved, but the ease of operation deteriorates
Solution Approach 1:
The rotation mechanism is designed to allow the workpiece to be easily rotated to the desired orientation before the locking mechanism is engaged. This preliminary rotation action separates the orientation adjustment phase from the securing phase, making the overall operation intuitive and manageable despite the presence of multiple mechanisms.

AI summary
An assembly for rotating a workpiece including a locking side pull hoist ring removably attachable to a side surface of the workpiece. The locking side pull hoist ring comprises a load bearing structure, a rotation mechanism attached to the side surface of the workpiece that rotates about a rotation axis extending through the rotation mechanism, a locking mechanism configured to transition between a locked state and an unlocked state, and a support member connecting the load bearing structure and the rotation mechanism. The support member rotatably supports the rotation mechanism for rotation about the rotation axis and rotatably supports the load bearing structure for rotation about a second axis. In the locked state, the locking mechanism prevents rotation of the rotation mechanism by securing the rotation mechanism to the support member.
