Wire Gripper Linkage Mechanism for Reduced Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wire grips are inefficient and apply excessive load to linear objects, leading to potential damage and reduced lifespan, especially in hazardous and confined work environments.
Innovation Solution
A wire grip design featuring a stationary-side and movable-side gripping portion with a connecting rod system that allows the movable-side gripping portion to move back and forth without applying a moment, reducing excessive load on the linear object, and enabling easy operation from the front side without worker movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pulling portion is pulled obliquely downward to grip the linear object, then the wire grip can be operated easily from the front side, but a clockwise moment is added to the wire grip causing excessive load on the linear object and potential curvature
Solution Approach 1:
The wire grip is divided into a stationary-side wire gripping portion and a movable-side wire gripping portion that can move independently. The movable-side portion is connected through action portions and a connecting rod, allowing the gripping force to be applied separately from the pulling direction, thus eliminating the moment that causes excessive load on the linear object.
Solution Approach 2:
The pulling direction is changed from oblique (causing moment) to substantially parallel with the linear object. The connecting rod transmits force in a different dimension (parallel to the object), while the action portions convert this motion into perpendicular movement of the movable-side gripping portion, achieving gripping without harmful moments.
2Productivity
If the movable-side wire gripping portion is moved by pulling obliquely, then the gripping action can be activated, but the wire grip structure experiences increased stress and reduced lifespan
Solution Approach 1:
The movable-side wire gripping portion is designed to move dynamically back and forth relative to the stationary-side portion. The action portions and connecting rod create a mechanical linkage that converts linear pulling motion into perpendicular gripping motion, allowing the gripping action to be activated without subjecting the structure to excessive stress from oblique pulling.
3Ease of operation
If a worker must move to insert and fix the linear object, then the gripping mechanism can be operated, but work efficiency is reduced in dangerous and confined environments
Solution Approach 1:
The wire grip is designed to be self-operating from the front side. The stationary-side wire gripping portion remains fixed while the movable-side portion automatically moves to grip the linear object when the connecting rod is pulled parallel to the object. This eliminates the need for the worker to move or reposition, significantly improving work efficiency in dangerous and confined environments.

AI summary
[Problem] Provided is a wire grip, which has excellent workability for bracing the wire and which can grip a linear object for bracing the wire without applying any excessive load to the linear object. [Solution) The wire grip comprises a stationary-side wire gripping portion provided with a body and having a substantially straight front shape, and a movable-side wire gripping portion arranged to face the stationary-side wire gripping portion and set movable back and forth with respect to the stationary-side wire gripping portion, whereby the linear object can be gripped between the stationary-side wire gripping portion and the movable-side wire gripping portion, wherein a first action portion for moving the movable-side wire gripping portion back and forth and a second action portion connected to the first action portion by a connecting rod are turnably attached at their individual ends to the body, wherein the other end of the first action portion and the other end of the second action portion are turnably attached to one end of the connection rod and an intermediate portion of the connection rod, respectively, wherein the other end of the connecting rod is pulled substantially parallel to the stationary-side wire gripping portion and the movable-side wire gripping portion so that the connecting rod, the second action portion and the first action portion are linked to act to move the movable-side wire gripping portion forward with respect to the stationary-side wire gripping portion.
