Hoist Ring Retainer With Spring-Loaded Arms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hoist rings face issues with the fastener easily disengaging and being lost during use, leading to inconvenient operation.
Innovation Solution
A hoist ring design incorporating a ring, a bolt, a retainer, and a spring, where the retainer's arms with abutting surfaces and a compression spring prevent disengagement by securely positioning the spring, ensuring the retainer remains attached to the ring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fastener is disposed to be connected between the ring and the bolt to allow the ring to rotate relative to the bolt and not rotate relative to the bolt, then the ring could not rotate relative to the bolt when the fastener is connected, but the fastener is easily disengaged from the ring and easily lost while in use
Solution Approach 1:
The retainer is designed to dynamically switch between two states: engaged with the bolt head to prevent rotation, and disengaged to allow rotation. The spring-loaded arms automatically engage with the bolt head's locking portions, providing reliable anti-rotation functionality when needed, while allowing easy disengagement when rotation is required
Solution Approach 2:
The retainer acts as an intermediary component between the ring and the bolt, providing a reliable connection mechanism. The spring-loaded arms with locking portions create an intermediate engagement system that ensures the fastener cannot easily disengage, solving the reliability issue while maintaining operational ease
2Stability of the object's composition
If a fastener is disposed to be connected between the ring and the bolt, then the ring could not rotate relative to the bolt when the fastener is connected, but the fastener is easily disengaged and lost
Solution Approach 1:
The spring-loaded arms provide dynamic engagement that maintains structural stability through automatic engagement with the bolt head's locking portions. The spring force ensures continuous contact and secure connection, preventing the fastener from being easily lost while maintaining the ability to rotate when disengaged
Solution Approach 2:
The spring component provides beforehand cushioning by maintaining constant engagement pressure on the locking portions. This pre-applied force ensures the retainer remains securely connected to the bolt head, preventing accidental disengagement and loss of the fastener during use
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design effectively prevents the retainer from disengaging from the hoist ring, enhancing usability by securely attaching the spring and retainer, thus preventing loss and ensuring reliable operation.
Implementation Method 1
Two ends of the spring respectively fit around the two arms. An inner edge of each of the two ends of the spring respectively abuts against each of the abutting surfaces of the two arms.

AI summary
A hoist ring includes a ring having a base portion and a ring portion connected to the base portion, a bolt, a retainer having a second locking portion and two arms, and a spring. The bolt coupled to the base portion has a head and a body connected to the head. The head has a first locking portion. The body is adapted to fix the ring to an object. The second locking portion is connected to the arms, and is adapted to be engaged with the first locking portion. The arms are spaced from each other by a distance, and are adapted to extend to two lateral sides of the ring portion. The arms are each respectively provided with an abutting surface. Two ends of the spring respectively fit around the arms. An inner edge of the ends of the spring respectively abuts against two abutting surfaces of the arms.
