Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single stereo structure abrasive paper is used, then the manufacturing process is simple, but the usage rate is low and application scenarios are limited
Solution Approach 1:
The abrasive paper is divided into multiple independent abrasive units (first abrasive and second abrasive) with different stereo particle layers on opposite surfaces. Each unit can be independently designed and manufactured, then combined into a composite structure that provides multiple functional surfaces for different grinding and polishing applications.
Solution Approach 2:
The composite abrasive paper is designed with multiple surfaces featuring different stereo particle layers (e.g., first stereo particle layer, second stereo particle layer, third stereo particle layer) that can handle various grinding and polishing tasks. This multi-functional design allows a single abrasive paper to replace multiple single-purpose abrasives, expanding application scenarios while maintaining manageable manufacturing complexity through modular construction.
2Duration of action of stationary object
If conventional abrasive paper is used, then the cost is high due to frequent replacement, but the grinding and polishing capability is maintained
Solution Approach 1:
The abrasive paper is pre-designed with multiple surfaces and multiple stereo particle layers during manufacturing. This preliminary preparation of multiple functional surfaces allows the abrasive paper to undergo multiple grinding and polishing cycles before replacement is needed, extending its service life and reducing the frequency of replacement compared to conventional single-surface abrasive paper.
Solution Approach 2:
The composite abrasive paper employs a nested structure where multiple abrasive units are integrated within a single paper substrate. The first abrasive and second abrasive units are positioned on opposite surfaces, with additional stereo particle layers nested within the structure. This nested arrangement maximizes the utilization of the abrasive paper by providing multiple active surfaces that can be sequentially used, thereby extending lifespan and reducing consumable costs.
3Productivity
If the abrasive paper is designed with multiple surfaces, then the usage rate increases, but the manufacturing complexity increases
Solution Approach 1:
The manufacturing process is segmented into independent stages for creating different stereo particle layers on separate surfaces. Each abrasive unit can be manufactured independently using standardized processes, then assembled into the final composite structure. This segmentation allows for optimized manufacturing of each component while maintaining overall productivity through efficient assembly of multiple surfaces.
4Adaptability or versatility
If the third stereo particle layer is exposed in the sealed cavity, then it can be used for grinding/polishing, but it may be forced against the first substrate during operation
Solution Approach 1:
A flexible microsphere layer is introduced as a cushioning element between the third stereo particle layer and the first substrate in the sealed cavity. This flexible layer prevents the third stereo particle layer from being forced directly against the rigid first substrate during grinding and polishing operations, maintaining structural stability and reliability while still allowing the third layer to function as an abrasive surface when exposed.

AI summary
A composite abrasive paper has at least three surfaces which polished and ground to improve the utilization rate of the abrasive paper and reduce the cost of grinding and polishing abrasive tools. The abrasive paper comprises a first abrasive comprising a first substrate, a first stereo particle layer provided on a surface of the first substrate, a flexible microsphere layer provided on a back surface of the first substrate; a second abrasive comprising a second substrate, a second stereo particle layer provided on surface of the second substrate, a third stereo particle layer provided on a back surface of the first substrate; the first and second abrasive are connected at an edge to form a connection part, the middle non-connection part of the first substrate and the second substrate forms a sealed cavity, the third stereo particle layer is provided opposite to the flexible microsphere layer in the sealed cavity.
