Animal Brush Cable Routing via Pivot Through Hole
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing animal brushing arrangements face issues with electric cable damage and motor shutdown due to reciprocating, twisting, and pinching movements when powering a rotating brush, especially when mounted on a stationary structure and used for larger animals.
Innovation Solution
An animal brushing arrangement with a movable brush and electric motor, where the electric cable is routed through a pivot arrangement with a through hole concentric with the pivot axis, minimizing twisting and protecting the cable from external influences, and incorporating a cable casing for added protection and a blocking arrangement to prevent complete revolution pivoting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electric cable is routed from the stationary structure to the electric motor on the movable brush, then electric power can be supplied to the motor, but the cable is subjected to reciprocating, twisting and pinching movements that may harm the cable and cause the motor to stop
Solution Approach 1:
A cable guide arrangement with a guide wheel is introduced as an intermediary between the electric cable and the movable brush. The guide wheel redirects the cable in a substantially transverse direction relative to the brush's movement, preventing the cable from being subjected to harmful reciprocating, twisting and pinching movements while still allowing electric power to be supplied to the motor on the movable brush
Solution Approach 2:
The cable routing is changed from a longitudinal path (parallel to brush movement) to a transverse path (perpendicular to brush movement) using the guide wheel. This dimensional change in cable orientation eliminates the harmful movements the cable experiences when routed directly to the movable brush
2Adaptability or versatility
If the brush is allowed to swing freely back and forth to reach different parts of the animal body, then the brushing arrangement is versatile and easy to use, but the electric cable experiences excessive twisting and stress
Solution Approach 1:
The cable guide arrangement with guide wheel acts as a mediator that allows the brush to swing freely for versatility while simultaneously preventing excessive cable twisting by redirecting the cable in a transverse direction, thus maintaining both adaptability and cable integrity
Solution Approach 2:
The cable guide arrangement dynamically adapts to the brush's swinging motion, allowing the brush to move freely to reach different parts of the animal body while the guide wheel continuously redirects the cable to prevent excessive twisting and stress during the dynamic operation

AI summary
An animal brushing arrangement includes a movable brush driven by an electric motor, a fixing part for attaching the arrangement to a stationary structure, and a first movable part which at a first end is pivotably attached to the fixing part by a first pivot arrangement to pivot about a first axis which is substantially horizontal when the fixing part is attached to the stationary structure and which allows the movable brush, suspended at a second end of the first movable part, to swing back and forth in at least one plane. An electric cable is provided to feed electric power to the electric motor. The first pivot arrangement is provided with a through hole and at least part of the through hole is arranged substantially concentrically with the first axis. The electric cable extends through the through hole.
