Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing abrasion removal systems for electromechanical machines are inadequate in efficiently removing carbon dust and maintaining optimal temperature control at the brush-slip ring contact region, leading to potential machine failures and increased maintenance costs.
Innovation Solution
A combined cooling and abrasion particles removal system that directs a gaseous medium flow towards the slip ring, creating a vortex to contain and remove abrasive particles, thereby preventing their spread and enhancing cooling efficiency, without the need for integrated fans, filters, or recirculated air flows.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If gaseous medium is directed across the face of multiple slip rings, then cooling is provided, but abrasive particles spread across slip rings
Solution Approach 1:
The patent applies local quality by directing the gaseous medium flow specifically towards the face of the slip ring at a controlled angle, creating a localized cooling zone that prevents particle spread to other slip rings. The flow is targeted rather than diffuse, providing cooling where needed without the harmful side effect of contaminating adjacent components.
2Object-generated harmful factors
If suction devices and cleaning brushes are used, then abrasion removal is provided, but system complexity increases
Solution Approach 1:
The patent extracts the harmful abrasive particles directly at their source by directing the gaseous medium flow towards the slip ring face, capturing particles before they can spread. This eliminates the need for separate suction devices and cleaning brushes, simplifying the overall system while maintaining effective particle removal.
Solution Approach 2:
The gaseous medium flow serves multiple functions simultaneously: it cools the slip ring, removes abrasive particles, and prevents particle spread. This multi-functionality replaces what would traditionally require separate dedicated systems for cooling and particle removal, reducing overall system complexity.
3Object-generated harmful factors
If conventional abrasion removal systems are used, then particle removal is provided, but cooling efficiency is insufficient
Solution Approach 1:
The patent merges the cooling function and abrasion particle removal function into a single integrated system. The gaseous medium flow performs both functions simultaneously by being directed towards the slip ring face, eliminating the need for separate cooling and particle removal systems and improving overall efficiency.

AI summary
The present invention relates to a combined cooling and abrasion particles removal system (1) and method for providing cooling and removing abrasion particles in a contact region (4) between a brush (2) and a slip ring (3) of an electromechanical machine, the system (1) comprising a passage for accommodating the brush (2) and having a front opening (15) adapted to face the slip ring (3), at least one supply tube (13a, 13b) with an outlet (16a, 16b) for blowing a gaseous medium (100) at least partially into a direction towards a free space (6) adjacent to the front opening (15), and at least one suction tube (14) with an inlet (17) opening for sucking off the gaseous medium and the abrasion particles from the free space (6). In order to pick up abrasion particles (104) and provide sufficient cooling, the free space (6) merges with a vortex chamber (21 a, 21 b) for generating a vortex (106) of the gaseous medium (100) carrying the abrasion particles (104) in operation of the system (1).
