Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the workbench is moved reciprocally along the X-axis to grind workpieces with different angles or irregular shapes, then the grinding wheel can contact the workpiece surface, but the movement distance is lengthened, increasing grinding time and reducing productivity
Solution Approach 1:
The invention dynamically adjusts the lapping path based on the actual workpiece profile detected during grinding. The control system modifies the movement trajectory of the workbench and grinder unit in real-time to match the workpiece geometry, avoiding unnecessary movements while ensuring complete surface coverage. This dynamic adaptation resolves the contradiction by making the system both versatile (adapting to different shapes) and productive (minimizing movement distance).
Solution Approach 2:
The invention implements a feedback mechanism where the control system continuously monitors the grinding process, detects the workpiece profile, and adjusts the lapping path accordingly. The detected workpiece geometry feeds back to the control algorithm, which optimizes the movement path to reduce grinding time while maintaining adaptability to various shapes and angles.
2Ease of operation
If a standard lapping path is used for all workpieces, then the grinding process is simple to control, but the movement distance increases for workpieces with different angles or irregular shapes, reducing productivity
Solution Approach 1:
The invention enables the grinding system to automatically determine and adjust its own operating parameters (lapping path) based on workpiece detection. The control system performs self-optimization by analyzing the detected workpiece profile and generating an optimized path without requiring manual intervention or complex pre-programming, thus maintaining ease of operation while improving productivity.
Solution Approach 2:
The invention changes the lapping path parameters dynamically based on the detected workpiece geometry. Instead of using a fixed standard path, the system adjusts movement distances, speeds, and trajectories according to the actual workpiece shape, achieving both operational simplicity through automated parameter adjustment and improved productivity through optimized paths.
3Productivity
If the workbench movement distance is shortened for workpieces with different angles or irregular shapes, then productivity is improved, but the grinding wheel may miss certain areas, reducing manufacturing precision
Solution Approach 1:
The invention uses dynamic path adjustment where the lapping trajectory is continuously modified based on real-time detection of the workpiece profile. The system ensures complete surface coverage by adapting the movement path to follow the actual workpiece geometry, preventing any areas from being missed while maintaining shortened movement distances for improved productivity.
Solution Approach 2:
The invention performs preliminary detection of the workpiece profile before generating the optimized lapping path. This preliminary action allows the control system to pre-calculate the exact movement trajectory needed to cover all surfaces, ensuring no areas are missed while minimizing the overall movement distance for enhanced productivity.

AI summary
A grinding machine includes a plane grinding mechanism carrying a workpiece, an electrically controlled device mounted on the plane grinding mechanism, a grinder unit rotatably mounted on the plane grinding mechanism to grind the workpiece, and a smart working control system mounted on the plane grinding mechanism and electrically coupled to the electrically controlled device. The smart working control system includes a smart coder and a smart driver. When a load and a cutting force produced between the grinder unit and the workpiece reach preset parameters during the grinding process, the smart driver executes the working sequence or parameter setting program edited by the smart coder, to shorten a movement distance of the workbench of the plane grinding mechanism along the X-axis (leftward and rightward), and to produce an optimum lapping path.
