Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cylindrical gap between the cover plate and main body is used for cooling fluid distribution, then the cooling fluid can be passed to the grinding layer, but the distribution is not uniform and service life is reduced
Solution Approach 1:
The single cylindrical gap is segmented into multiple first passages arranged on the surface of the main body or cover plate. These passages are distributed across different locations to provide uniform cooling fluid delivery to various zones of the grinding layer, replacing the single centralized gap with multiple targeted channels.
Solution Approach 2:
The cooling fluid distribution is optimized by placing passages at specific locations on the main body or cover plate surface. Each passage is positioned to deliver cooling fluid to specific areas of the grinding layer where it is most needed, creating localized quality improvements in cooling efficiency and surface finish.
2Productivity
If the cover plate is positioned at a spacing from the main body to form a cylindrical gap, then cooling fluid can flow through, but material removal efficiency and surface quality are insufficient
Solution Approach 1:
The cooling function is segmented into multiple first passages that enable simultaneous cooling of different grinding zones. This allows for more efficient material removal across the entire grinding surface while maintaining uniform surface quality through distributed cooling.
Solution Approach 2:
The cooling fluid is delivered to the grinding layer through pre-positioned passages before the grinding contact occurs. This preliminary cooling action prevents excessive heat buildup during material removal, maintaining both productivity and surface finish quality.
3Manufacturing precision
If a single feed for cooling fluid is used, then the structure is simple, but the cooling fluid distribution to the grinding layer is not uniform
Solution Approach 1:
The single feed is segmented into multiple first passages that distribute cooling fluid to different areas of the grinding layer. This segmentation achieves uniform cooling distribution while keeping the overall structure relatively simple by using straightforward passage geometry.
Solution Approach 2:
The passage configuration provides localized cooling quality improvement by directing cooling fluid to specific areas where it is needed most, achieving uniform overall distribution through targeted local delivery points.

AI summary
A grinding tool for grinding an engine includes a main body with a central coupling region for connecting to a rotary drive of a grinding machine, the main body having a substantially rotationally symmetrical configuration with respect to an axis of rotation. The grinding tool also includes a grinding layer on the main body that extends over an outer circular ring zone of the main body, at least one feed for a cooling fluid, and a substantially circular cover plate arranged substantially normal to the axis of rotation and forming an axial gap on the main body. The axial gap is in fluid communication with the feed and the grinding layer so that a cooling fluid fed by the feed can be passed via the axial gap to the grinding layer.
