Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional manual sampling and laboratory testing methods are used, then mechanical parameters can be obtained, but rock disturbance and water saturation changes occur during transportation, reducing measurement accuracy
Solution Approach 1:
The system performs mechanical loading tests on rock slag immediately after excavation while the material is still on the conveyor belt, before any transportation or laboratory processing occurs. This preliminary action prevents rock disturbance and water saturation changes that would occur during sample transport to the laboratory, thereby maintaining measurement accuracy.
Solution Approach 2:
The patent replaces traditional manual sampling and laboratory mechanical testing with an automated on-site mechanical loading system. The loading device applies controlled forces directly to rock slag on the conveyor belt and uses sensors to measure mechanical parameters, eliminating the need for manual sample collection and transportation to the laboratory.
2Measurement precision
If manual sampling and laboratory testing are used, then mechanical parameters can be measured, but significant manual intervention is required, reducing productivity
Solution Approach 1:
The system automatically performs mechanical loading tests, data collection, and analysis without requiring manual intervention. The loading device, sensors, and control system work together to conduct tests on rock slag as it passes on the conveyor belt, eliminating the need for operators to manually collect samples and perform laboratory tests, thereby improving productivity.
Solution Approach 2:
The mechanical parameter measurement system operates continuously as rock slag moves along the conveyor belt, performing tests without interruption. This continuous measurement process eliminates the discontinuous nature of manual sampling and batch laboratory testing, maintaining constant productivity while ensuring accurate mechanical parameter data is obtained for every rock slag sample.
3Extent of automation
If real-time measurement is implemented, then intelligent control and prediction can be achieved, but automated loading and sensing systems are required, increasing device complexity
Solution Approach 1:
The loading device is designed to perform multiple functions: it applies controlled mechanical loads to rock slag, positions samples accurately, and integrates with the conveyor belt system. The sensing system simultaneously measures multiple parameters including force, displacement, and material properties. This multi-functionality reduces the need for separate specialized devices, thereby managing complexity while enabling intelligent control.
4Productivity
If on-site mechanical loading is performed, then real-time data can be collected, but automated handling and positioning mechanisms are needed, increasing ease of operation requirements
Solution Approach 1:
The patent merges the handling device, positioning mechanism, and loading device into an integrated system that operates automatically. The handling device transfers rock slag from the conveyor belt to the loading position, the positioning mechanism aligns samples automatically, and the loading device applies tests without manual intervention. This merging of functions into a coordinated automated system improves productivity while managing operational complexity through unified control.
