Split Blow-Off Ring Structure for Cleanable Motor Nozzles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blow-off rings for cleaning electric motor components, such as stator windings, are prone to nozzle bending and blocking, leading to incomplete cleaning and potential costly repairs or disposal, as they cannot effectively clean both inner and outer surfaces without risking damage.
Innovation Solution
A blow-off ring design comprising two interlocking L-shaped or stepped ring elements with nozzles integrated as bores, allowing for easy disassembly and cleaning of nozzles from both sides, improved stability, and the use of stainless steel for resistance to mechanical and chemical cleaning, ensuring effective cleaning of both inner and outer surfaces without deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a copper ring with many nozzles is used to clean the stator, then the cleaning coverage is improved, but the nozzles become bent and blocked during use
Solution Approach 1:
The blow-off ring is divided into two separate L-shaped ring elements that can be disassembled. This segmentation allows each element to be structurally optimized and enables easy access for cleaning and maintenance of nozzles, preventing bending and blocking issues
Solution Approach 2:
The blow-off ring is designed to be dynamically disassemblable into two L-shaped elements. This dynamic structure allows the ring to be taken apart for nozzle maintenance and cleaning, ensuring reliable operation by preventing nozzle blockage while maintaining complete cleaning coverage when assembled
2Stability of the object's composition
If the blow-off ring is made as a single integrated structure, then the structural stability is improved, but the nozzles become difficult to clean and maintain
Solution Approach 1:
The integrated structure is segmented into two L-shaped ring elements that interlock to form the complete circular blow-off ring. When assembled, the structure provides full stability for effective cleaning. When disassembled, the segmented design allows easy access to nozzles for cleaning and maintenance from both inside and outside
3Productivity
If the nozzles are oriented only for outward cleaning, then the cleaning effectiveness on outer surfaces is improved, but the inner surfaces cannot be cleaned
Solution Approach 1:
The blow-off ring is segmented into two L-shaped elements that can be disassembled. This allows nozzles to be cleaned and reoriented from both sides, enabling the ring to adapt to different cleaning requirements - cleaning outer surfaces when assembled and allowing inner surface access when disassembled
Solution Approach 2:
The dynamic disassemblability of the blow-off ring enables versatile nozzle orientation. Nozzles can be cleaned and adjusted from both inside and outside, allowing the system to adapt to different cleaning scenarios and maintain effectiveness on both inner and outer surfaces
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design enables safe, reliable, and cost-effective cleaning of electric motor components, reducing the need for costly repairs and rejects by allowing for easy maintenance and precise orientation of nozzles, ensuring consistent cleaning performance.
Implementation Method 1
fluid flowing out through the nozzles, as a result of which the blow-off effect is produced
Implementation Method 2
The first ring element and the second ring element can be put together in order to enclose an annular cavity in this way
Implementation Method 3
an excess pressure has to be generated within the annular cavity. This excess pressure leads to fluid flowing out through the nozzles

AI summary
A blow-off ring for cleaning components of an electric motor includes a first ring element and a second ring element, where the first ring element and the second ring element can be assembled in order to enclose an annular cavity within the blow-off ring. The first ring element and/or the second ring element has nozzles which are connected to the annular cavity and which extend along an inner circumferential surface and/or an outer circumferential surface of the blow-off ring.
