Wire Gripper with Swinging Member for Safe High-Place Tensioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wire grippers used for overhead wire distribution line tensioning face issues with excessive force application and weight, making them difficult to use safely and efficiently, especially in high-place work environments where contact with active wires can be hazardous.
Innovation Solution
A wire gripper design featuring a stationary gripping body, a swinging member, and a connection member with a grip portion that allows for easy attachment and detachment by hand, reducing weight and enhancing safety through a mechanism that includes a connection member guiding portion and a suppressing mechanism to maintain tension without changing the spacing between gripping components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the wire gripper is made robust with thicker portions to withstand excessive force, then the strength and reliability are improved, but the weight increases making it difficult to use at high places
Solution Approach 1:
The patent changes the material parameters and structural dimensions of the wire gripper to achieve optimal strength-to-weight ratio. The gripping bodies and connection members are designed with specific thickness parameters that provide sufficient strength while minimizing weight for high-place operations
Solution Approach 2:
The wire gripper employs composite construction with different materials for various components. The gripping bodies, connection members, and swinging elements use material combinations that provide high strength where needed while keeping overall weight low for safe handling at heights
2Ease of operation
If the wire gripper design is simplified for easy operation at high places, then the ease of operation is improved, but the ability to withstand excessive force and shearing may be compromised
Solution Approach 1:
The wire gripper is divided into separate components including gripping bodies, connection members, and swinging elements that can be easily assembled and disassembled. This segmentation enables simple operation for attachment and detachment while each component is designed to withstand the required forces when properly assembled
Solution Approach 2:
The wire gripper incorporates self-locking and self-adjusting features through its swinging member mechanism and connection member design. The structure automatically maintains proper tension and positioning without requiring complex operational procedures, ensuring both ease of use and reliable performance under load

Implementation Method 1
a swinging member swingably attached to a wire gripper main body by a supporting shaft
Implementation Method 2
a swinging member swingably attached to a wire gripper main body by a supporting shaft; a movable gripping body having a wire-like body holding portion and swinging toward the wire-like body pressing-down portion of the stationary gripping body according to swinging of the swinging member
Implementation Method 3
a connection member coupled to the swinging member by a connection member swinging shaft and swinging the swinging member
Implementation Method 4
the grip portion has a shape grasped with a hand of a person, and is configured to extend in a direction in which the connection member extends when the connection member is pulled

AI summary
A wire gripper having a lightweight feeling and enabling attaching work to a wire-like body to be performed easily and safely, which comprises: a fixed gripping body having a wire-like body pressing-down portion; a swinging member; a movable gripping body having a wire-like body holding portion; and a connection member coupled to the swinging member by a connection member swinging shaft and allowing the swinging member to swing. A wire gripper main body is provided with an first-finger hooking portion in a connection member guiding portion for guiding the connection member when pulling the connection member and attached with a grip portion in a freely swingably movable manner, on the side toward which the connection member is pulled, so that the grip portion faces the first-finger hooking portion. The grip portion is structured so as to be able to apply tension in order to pull the connection member.
