Resilient Linkage Ball Holder for Tractor Implement Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage solutions for linkage balls on agricultural tractors are complex and prone to misplacement or loss, requiring multi-part mechanical assemblies that are cumbersome and inefficient for field use.
Innovation Solution
A tulip-shaped linkage ball holder made from resiliently deformable materials, such as rubber, plastics, or spring steel, which clasp around the linkage ball for secure storage without the need for complex locking mechanisms, allowing easy insertion and removal while retaining the ball during transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multi-part mechanical assemblies are used to retain unused linkage balls, then the linkage balls can be stored on the tractor, but the storage system becomes complex and operators must perform multiple steps in correct order, increasing the risk of misplacement and loss
Solution Approach 1:
The holder is divided into a base portion and multiple fingers that can independently deform. This segmentation allows each finger to independently adapt to the linkage ball, providing reliable retention through simple elastic deformation rather than complex mechanical interlocking
Solution Approach 2:
The holder utilizes elastic deformation of the resiliently deformable material to change its physical state from rigid to flexible during ball insertion, then returns to a rigid state for retention. This parameter change enables the holder to adapt to different ball sizes while maintaining simple construction
2Ease of operation
If toolboxes or storage compartments are used to store unused linkage balls, then balls can be stored away from the linkage, but operators may misplace balls or find them inconveniently stored relative to the linkage location
Solution Approach 1:
The holder is mounted adjacent to the linkage at the same operational level, making the ball storage location equally accessible whether the ball is in use or stored. This eliminates the need to move balls between distant storage compartments and the linkage, improving both accessibility and retention reliability
Solution Approach 2:
The holder automatically retains the linkage ball through elastic deformation of its fingers, requiring no additional locking mechanisms or operator actions. The ball is self-retained simply by being placed in the holder, eliminating misplacement risks associated with complex storage systems
3Ease of operation
If a resiliently deformable holder with multiple fingers is used to store linkage balls, then easy insertion and removal of balls is achieved, but the holder must be made from flexible materials which may reduce structural strength
Solution Approach 1:
The holder uses thin resiliently deformable fingers that are flexible enough to deform during ball insertion but maintain sufficient structural strength through elastic recovery. The thin-finger design provides the necessary flexibility for easy operation while the resilient material properties ensure adequate strength for retention during transport
Solution Approach 2:
The holder can be constructed from composite materials combining resilience and strength, such as spring steel or reinforced plastics. These composite materials provide both the elastic deformation needed for easy insertion and the structural strength required for reliable retention under various operating conditions

AI summary
There is described an agricultural tractor having an implement hitch or linkage which is arranged to receive linkage balls of different types. The tractor is provided with at least one linkage ball holder which can be used to store unused linkage balls on the tractor. The linkage ball holder is at least partly formed from a resiliently deformable material, such that a linkage ball can easily be retained within the holder without the need for additional mechanical locking parts.
