Solution Overview

Problem

Existing wire strand attachment devices for fences are time-consuming and cumbersome to use, particularly when attaching multiple wire strands to metal support posts, requiring tools like wire pullers and lacking efficiency and cost-effectiveness.

Innovation Solution

A wire strand attachment clip with a wire catch and multiple attachment arms configured to snap onto T-shaped support posts, providing a secure and easy attachment method for wire strands without the need for additional tools, allowing for quick and cost-effective installation of multiple strands.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional wire strand attachment devices are used, then wire strands can be secured to support posts, but the installation process becomes time-consuming and requires additional tools like wire pullers

Engineering Contradiction:
Improveease of attachmentVSAvoidinstallation time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The attachment device is divided into separate functional components: a U-shaped body for securing to the post, wire catch members for engaging the wire strand, and attachment arms that connect them. This segmentation allows each component to be optimized independently and simplifies the overall attachment process

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The attachment device is designed to be self-installing without requiring external tools like wire pullers. The spring-biased wire catch members automatically engage the wire strand when the attachment arms are positioned, and the device can be secured to the post by hand-tightening the body against the post surface

Inventive Principle:
Principle #25Self-service

2Productivity

If multiple wire strands are attached using traditional methods, then complete fence construction is achieved, but the process becomes cumbersome and costly

Engineering Contradiction:
Improveinstallation efficiencyVSAvoidattachment device complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The attachment device is designed with multiple wire catch members (typically three) that can simultaneously engage multiple wire strands. The U-shaped body and attachment arms are configured to work with various wire strand configurations, making the device versatile for different fence construction scenarios and reducing the need for multiple specialized tools

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The device combines the functions of wire securing, strand engagement, and attachment in a single integrated component. The U-shaped body, wire catch members, and attachment arms work together as one unit, eliminating the need for separate tools for each function and streamlining the installation process

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A wire strand attachment clip including a wire catch that defines a wire strand receiving and holding area configured to receive a wire strand, and a plurality of attachment arms connected to and extending from the wire catch that are dimensionally and biasingly configured to be positioned on a support post to attach the wire strand to that support post such that the attachment arms engage multiple surfaces of the support post.
