Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing abrasion removal systems for electric machine brushes are inadequate in effectively removing carbon dust, leading to contamination and potential machine failures due to insufficient removal efficiency.
Innovation Solution
An abrasion removal system that uses a housing with precision-designed supply and outlet tubes to disperse and capture carbon dust using a gaseous medium and suction system, ensuring the dust is contained within the housing and prevented from escaping, with a compressor providing pressure and a ventilator generating suction to efficiently remove and store the abrasions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional suction devices are used to remove carbon dust from brushes, then some carbon dust is removed, but the removal efficiency is insufficient leading to contamination and potential machine failures
Solution Approach 1:
The invention applies pneumatic principles by using a two-stage suction system with a first suction device creating a first suction effect and a second suction device creating a second suction effect. The housing is divided into a first volume and a second volume separated by a partition wall, with the first suction device drawing air and abrasions from the first volume while the second suction device draws air and abrasions from the second volume. This pneumatic approach significantly enhances the removal efficiency of carbon dust compared to conventional single-stage suction devices.
2Productivity
If a simple suction device is used, then the device complexity is low, but the removal efficiency of carbon dust is inadequate
Solution Approach 1:
The invention segments the suction system into two independent suction devices, each responsible for a specific volume of the housing. The housing is divided by a partition wall into a first volume and a second volume, with the first suction device serving the first volume and the second suction device serving the second volume. This segmentation allows each suction device to be optimized for its specific task while maintaining overall system efficiency, and facilitates easier maintenance and operation.
3Reliability
If carbon dust is not effectively removed from brushes, then the system is simpler to operate, but carbon dust contaminates the electric machine and can cause short-circuits
Solution Approach 1:
The invention introduces an intermediary partition wall that separates the housing into distinct volumes, allowing controlled air flow and abrasion removal. The partition wall acts as a mediator between the two suction zones, enabling the system to effectively capture carbon dust from different regions of the brush assembly. This intermediary structure ensures comprehensive dust removal while maintaining organized air flow patterns, thereby protecting the electric machine from contamination.
