Solution Overview
Problem
Existing grinding machines lack the capability to produce a variety of different grinding marks, often resulting in limited design options and conspicuous patterns, which can be costly and restrictive in terms of equipment.
Innovation Solution
A grinding machine with a movable plate that can be adjusted to create irregular patterns on the workpiece surface by applying non-homogeneous pressure through a structured plate and controlled movement, combined with a pressure beam and a drive device for random movement, allowing for diverse and unpredictable grinding patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed grinding belt arrangement is used, then the grinding process is simple and stable, but the variety of grinding patterns is limited
Solution Approach 1:
The patent introduces a movable plate that can be displaced in the transverse direction between the grinding belt and workpiece. This dynamic element allows the plate to vary its position during or between grinding operations, creating different grinding patterns without requiring multiple fixed grinding units. The mobility of the plate transforms a static system into a dynamic one, enabling pattern variety while maintaining equipment simplicity.
Solution Approach 2:
The single movable plate serves multiple functions: it applies pressure to the grinding belt, it creates various grinding patterns through transverse displacement, and it can be repositioned to generate different mark orientations. This multi-functional component replaces what would otherwise require multiple specialized grinding units, reducing device complexity while enhancing adaptability.
2Manufacturing precision
If multiple grinding units are combined to improve surface quality, then the grinding result homogeneity is improved, but the equipment complexity increases
Solution Approach 1:
Instead of using multiple fixed grinding units arranged at different angles, the patent employs a single movable plate that can be dynamically repositioned in the transverse direction. This dynamic positioning allows the same grinding belt to create varied grinding patterns and mark orientations, achieving surface quality homogeneity without the complexity of multiple grinding units.
Solution Approach 2:
The patent changes the positional parameter of the plate in the transverse direction to vary the grinding pattern. By adjusting the plate's position rather than changing the grinding unit configuration, the system achieves different surface patterns using the same physical components, thereby improving surface quality without increasing equipment complexity.
3Adaptability or versatility
If the plate is moved perpendicular to the pressure direction, then different grinding patterns are created, but additional drive mechanisms are required
Solution Approach 1:
The drive device serves dual functions: it moves the plate in the longitudinal direction for grinding operations and can also displace the plate in the transverse direction to create different patterns. This multi-functional drive mechanism eliminates the need for separate transverse positioning systems, achieving pattern variety without proportionally increasing drive device complexity.

Function Achieved in This Case
This configuration enables the production of a wide range of unique grinding patterns without repetitive designs, enhancing the variety of possible outcomes and allowing for more flexible and aesthetically pleasing surface finishes.
Implementation Method 1
the at least one pressure bar exerts pressure on the plate located between the grinding belt and the pressure bar, which is transmitted to the grinding belt
Implementation Method 2
If, during this grinding process, the plate is moved in a direction perpendicular to the direction of pressure, i.e., in most cases parallel to the surface being ground, a shear force is exerted on the grinding belt
