Snap-Fit Ball Retainer Joint for Flexible Load Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional ball retainers with end-to-end connected chain belts lack flexibility, leading to reduced load capacity and potential cracking at joints, especially at turning points or where travel is unsmooth, resulting in operational issues and reduced service life.
Innovation Solution
A ball retainer design featuring a hook-like structure at one end and a recess at the other, allowing for elastic deformation and disengagement during stress or obstruction, enabling flexible operation and reconnection to maintain smooth operation and prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If an end-to-end connected chain belt structure is used to improve load capacity, then the structural strength is improved, but the flexibility at joints is reduced
Solution Approach 1:
The joint structure transitions from a fixed rigid connection to a dynamic system where the ball can move between the accommodation portion and the limiting portion, allowing the joint to adapt its state between connected and disconnected based on operational conditions, thereby maintaining both strength and flexibility
Solution Approach 2:
The joint is segmented into separate functional components: the hook portion with accommodation portion for connection, the limiting portion for disconnection, and the ball as a movable element. This segmentation allows independent optimization of each component's function while maintaining overall system performance
2Stability of the object's composition
If a rigid end-to-end connection is used to maintain structural integrity, then the stability is improved, but the ability to handle turning points and unsmooth travel is reduced
Solution Approach 1:
The joint's connection state parameter changes dynamically based on operational parameters. When operational conditions become severe (turning points, unsmooth travel), the ball moves to the limiting portion, changing the connection state from engaged to disengaged, allowing the system to adapt to varying operational demands
3Strength
If the hook portion is continuously connected to the recess portion to maintain load bearing, then the load capacity is improved, but the risk of cracking and element failure under excessive force is increased
Solution Approach 1:
The limiting portion serves as a pre-prepared safety mechanism that activates before catastrophic failure can occur. When excessive force is detected through ball movement, the joint disconnects in advance, preventing the propagation of cracks and protecting other elements from damage
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 hook-like structure enhances flexibility and load capacity, preventing joint cracking and ensuring continuous smooth operation by allowing disengagement and reconnection, thus extending the service life and avoiding damage from excessive forces or obstructions.
Implementation Method 1
The second connecting section has an amount of elastic deformation. When an acting force is applied to the chain belt so that the first end and the second end are moved away from each other after the hook portion is snapped into the recess portion, the second connecting section is elastically deformed, so that the hook portion is disengaged from the recess portion.

AI summary
A ball retainer is provided. The ball retainer includes a chain belt, a hook portion, and a recess portion. The chain belt has a first end and a second end. The hook portion is disposed at the first end. The recess portion is disposed at the second end. An outer circumferential side and an inner circumferential side are formed after the hook portion of the ball retainer is snapped into the recess portion. During operation of the ball retainer after the hook portion is snapped into the recess portion, an acting force is applied to the chain belt so that the hook portion is disengaged from the recess portion. During operation of the ball retainer after the acting force disappears, the first end and the second end of the chain belt approach each other so that the hook portion is accordingly snapped into the recess portion.
