Fence Stretcher Rod Weaving Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fence stretchers with rectangular links are labor-intensive to use, requiring multiple bolts to be unscrewed, oriented, and tightened, which can take hours for multiple sections, and are prone to loss in grass environments.
Innovation Solution
A fence stretcher system comprising a body with a rod and rod-holder for weaving into fence links, hooks for engaging the rod, and an interface for efficient stretching, allowing quick attachment and detachment without deformation of the links.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional clamps with bolts are used to stretch fence, then the fence can be securely held, but the operation becomes labor-intensive and time-consuming
Solution Approach 1:
The patent removes the bolts and nuts from the clamp assembly, extracting the problematic fastening components. The rod passes through the fence links without requiring bolt insertion or removal, eliminating the labor-intensive bolt tightening and loosening operations while maintaining secure holding through the rod's physical presence and the clamp's gripping action on the rod.
Solution Approach 2:
The clamp is divided into separate functional components: the body that grips the rod, the rod-holder that positions the rod, and the hooks that engage the rod. This segmentation allows the rod to be freely inserted and removed without manipulating multiple bolts, while each component independently contributes to secure holding.
2Reliability
If conventional clamps with numerous bolts are used, then the fence can be firmly secured, but the bolts are easily dropped and lost in grass environments
Solution Approach 1:
The patent completely removes bolts and nuts from the system, extracting the loss-prone fastening components. The rod serves as a permanent, integrated component that cannot be lost, while the clamp's gripping mechanism maintains firm securing without requiring removable fasteners.
Solution Approach 2:
The rod acts as an intermediary element that permanently connects the clamp to the fence links. Instead of using removable bolts that can be lost, the rod serves as a durable mediator that maintains the connection through its physical presence and the clamp's gripping action, eliminating the risk of bolt loss in grass environments.
3Reliability
If conventional clamps require multiple bolt tightening steps are used, then the fence can be properly secured, but the process takes several minutes per section
Solution Approach 1:
The patent removes the time-consuming bolt tightening steps by extracting the bolt and nut fastening mechanism. The rod can be quickly inserted through the fence links and secured by the clamp's gripping action, eliminating several minutes of bolt manipulation per section and significantly increasing stretching productivity while maintaining proper securing.
Solution Approach 2:
The rod is pre-positioned in the rod-holder before engagement with the fence, and the clamp is pre-configured with its gripping mechanism. This preliminary preparation allows for rapid deployment and securing of each fence section without the need for time-consuming bolt tightening steps during the stretching operation.
4Reliability
If conventional clamps with multiple bolts are used, then the fence can be securely attached, but the attachment process becomes complex and lengthy
Solution Approach 1:
The patent removes the complex bolt and nut assembly from the clamp, extracting the source of attachment complexity. The simplified design uses a rod that passes through the fence links and is secured by the clamp's gripping mechanism, dramatically reducing attachment complexity while maintaining secure attachment through the rod's stable positioning and the clamp's holding action.

AI summary
A fence stretcher system and method are shown and described. In one embodiment, the fence stretcher system comprises a body. A rod having a diameter configured to allow the rod to be woven into a fence's links may be attached to the body. A rod-holder having a diameter sized to receive the rod may also be attached to the body. A plurality of hooks configured to engage the rod when the rod is woven into the fence may also be attached to the body. An interface may also be attached to the body. Using this system, fence may be quickly and easily stretched with minimal link displacement.
