Wire Twisting Mechanism With Synchronized Length Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing central twisting machines for wires are limited by height and length restrictions, are complex, and do not provide balanced forces during twisting, leading to wire shortening and instability.
Innovation Solution
A twisting apparatus and method where the second holder and twisting unit move relative to the first holder in the same direction, preferably horizontally, synchronized by a gear mechanism, to compensate for length reduction and improve force balance during twisting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wires are twisted on central twisting machines, then electromagnetic compatibility is improved, but wire length is shortened
Solution Approach 1:
The patent applies dynamics by making the holders movable rather than fixed. The first holder can move along the wire's longitudinal axis to compensate for length reduction during twisting. This dynamic adjustment allows the twisting operation to proceed while maintaining the required wire length, resolving the contradiction between achieving electromagnetic compatibility through twisting and preserving wire length.
2Length of moving object
If vertical motion of twisting head is used to compensate for wire shortening, then wire length is maintained, but device complexity increases
Solution Approach 1:
The patent segments the twisting system into separate functional components: a first holder for securing the wire end, a second holder for gripping the wire during twisting, and a twisting unit. The first holder is independently movable along the longitudinal axis, allowing it to compensate for wire shortening without requiring complex vertical motion mechanisms. This segmentation simplifies the overall device structure while maintaining wire length.
3Length of moving object
If vertical motion mechanism is added for length compensation, then wire length is maintained, but height limitation is imposed
Solution Approach 1:
Instead of using vertical motion (one-dimensional solution) to compensate for wire shortening, the patent moves the first holder along the wire's longitudinal axis (another dimension). This dimensional change allows for length compensation without imposing height limitations on the twisting head, as the motion occurs horizontally along the wire rather than vertically within a limited space.
4Reliability
If gripping mechanism rotates to twist wires, then electromagnetic compatibility is improved, but balanced force is not provided
Solution Approach 1:
The patent applies the counterweight principle by positioning the movable first holder to balance the forces during twisting. As the second holder grips and the twisting unit rotates the wire, the first holder moves along the longitudinal axis to counterbalance the tension and compression forces, providing force balance that stabilizes the twisting operation and improves electromagnetic compatibility.
