Offset Guide Walls for Anti-Twist Cable Component
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-rotation components for power cables in electrical machines often fail to prevent unwanted twisting effectively, particularly when connected to power connection bolts, and are complex to manufacture using injection molding.
Innovation Solution
A plastic anti-rotation component with laterally arranged guide walls that form an intermediate receiving path, allowing only limited twisting before contact with the guide walls, and featuring offset demolding paths for easy manufacturing, is designed to prevent unwanted pivoting of power cables connected to electrical machines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If guide walls are arranged to effectively prevent cable twisting, then anti-rotation reliability is improved, but manufacturing complexity increases due to demolding difficulties
Solution Approach 1:
The guide walls are arranged asymmetrically with respect to the longitudinal direction of the receiving path. Specifically, the guide walls are offset from the central axis, creating an asymmetric configuration that allows demolding slides to access the cavity from lateral directions. This asymmetric arrangement enables the demolding process while maintaining the anti-rotation function, as the guide walls still effectively limit cable twisting despite their offset positioning.
Solution Approach 2:
The solution transitions from a traditional axial demolding approach to a lateral demolding approach by arranging guide walls offset from the central axis. This creates demolding paths in a different dimension (lateral direction rather than axial direction), allowing the injection mold to successfully remove the complex anti-rotation component without compromising the guide wall configuration needed for anti-rotation reliability.
2Stability of the object's composition
If guide walls are positioned to maximize twisting prevention, then cable positioning stability is improved, but demolding accessibility deteriorates
Solution Approach 1:
The guide walls are positioned asymmetrically relative to the receiving path's longitudinal direction, creating an offset configuration. This asymmetric positioning allows the guide walls to extend sufficiently to prevent cable twisting while leaving lateral spaces that provide access for demolding slides. The offset arrangement ensures that the guide walls maintain their stabilizing function while enabling manufacturing accessibility from the sides.
Solution Approach 2:
The anti-rotation component is designed with guide walls that are segmented or offset from the central axis, creating distinct functional zones. The guide walls are positioned to provide cable stabilization in one region while leaving other regions accessible for demolding operations. This segmentation of functional zones allows simultaneous achievement of cable positioning stability and manufacturing ease.

AI summary
The invention relates to a plastic anti-twist component for an electric cable on an electric machine, which component has guide walls that bound a receiving path lying therebetween for receiving and rotationally securing the electrical cable. Two guide walls are arranged at an offset from each other in the longitudinal direction of the receiving path lying therebetween, wherein two mold-removal paths running opposite each other and arranged at an offset are formed orthogonal to the receiving path.
