Rotating End Angle Restriction for Electrical Wire Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electrical wire guiding apparatuses fail to define the inclination angle of the rotating end due to sliding caused by gravity and reaction forces, making angle management difficult.
Innovation Solution
Incorporating an angle restriction edge on the bracket or rotating end that abuts against an opposing member to restrict the inclination angle, with a groove-shaped configuration for enhanced reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the rotating end is held in the bracket with spherical surface contact structure allowing rotation in any direction, then the electrical wire guide can flexibly adapt to movement, but the inclination angle of the rotating end cannot be defined and varies greatly due to sliding
Solution Approach 1:
The spherical contact surface is segmented by adding an angle restriction edge that divides the continuous rotation space into defined angular segments. This segmentation allows the rotating end to maintain rotational capability while restricting it to specific angular positions, thereby defining the inclination angle.
Solution Approach 2:
The angle restriction edge acts as a preliminary anti-action mechanism by pre-defining the permissible angular range before the rotating end can slide freely. The opposing members on the bracket create preliminary constraints that prevent excessive sliding while maintaining the desired inclination angle.
2Ease of operation
If the rotating end is allowed to rotate freely in any direction, then the electrical wire guide can accommodate complex movements, but management of the inclination angle becomes difficult
Solution Approach 1:
The angle restriction edge serves as an intermediary element between the rotating end and the bracket. It mediates the rotation freedom by introducing controlled constraints through opposing members, making the inclination angle manageable while preserving essential rotational capability.
3Manufacturing precision
If angle restriction edges are added to the bracket or rotating end, then the inclination angle can be defined, but the device complexity increases
Solution Approach 1:
Instead of modifying the entire spherical contact structure, the angle restriction edge is applied locally at specific positions on the bracket or rotating end. This local modification approach defines the inclination angle with minimal additional complexity, as only specific regions are constrained rather than the entire rotation mechanism.

AI summary
An electrical wire guiding apparatus that can define the inclination angle of a rotating end. The electrical wire guiding apparatus includes: a bracket that is to be fixed to a mounting portion, a rotating end that is arranged at an end portion of an electrical wire guide and is held in the bracket in a manner of being able to rotate in any direction, the electrical wire guide surrounding electrical wires and being able to bend in a predetermined shape; and angle restriction edges that are provided on the bracket and the rotating end and restrict the angle of the rotating end by abutting against opposing members when the rotating end becomes inclined at a predetermined angle.
