Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If full-scale conveyor testing is conducted to detect abrasion, then measurement accuracy is improved, but device complexity and cost increase significantly
Solution Approach 1:
The patent segments the complex conveyor system into isolated friction pairs (scraper and middle groove) and tests them separately using a simplified experimental装置. This allows abrasion detection without requiring full-scale conveyor testing, reducing device complexity while maintaining measurement precision for the specific friction interface.
Solution Approach 2:
The patent creates a simplified copy of the actual conveyor friction interface by constructing an experimental装置 that replicates the essential friction pair characteristics. This copy enables accurate abrasion measurement without needing the complete conveyor system, resolving the contradiction between measurement accuracy and device complexity.
2Reliability
If new materials are tested on actual conveyers, then friction simulation accuracy is improved, but material consumption and cost increase
Solution Approach 1:
The patent creates a simplified copy of the actual conveyor friction interface by constructing an experimental装置 that replicates the essential friction pair characteristics. This copy enables accurate abrasion measurement without needing the complete conveyor system, resolving the contradiction between measurement accuracy and device complexity.
Solution Approach 2:
The patent changes the testing parameters from full-scale conveyor operation to controlled laboratory conditions with adjustable speed and load. This allows multiple material tests without consuming excessive materials, as the same experimental setup can be reused with different test pieces under varying parameters.
3Reliability
If scraper conveyer middle grooves are tested frequently to detect abrasion, then reliability is improved, but productivity decreases due to testing time and material loss
Solution Approach 1:
The patent creates a simplified copy of the actual conveyor friction interface by constructing an experimental装置 that replicates the essential friction pair characteristics. This copy enables accurate abrasion measurement without needing the complete conveyor system, resolving the contradiction between measurement accuracy and device complexity.
Solution Approach 2:
The patent performs preliminary abrasion testing on material samples before they are installed on actual conveyors. This preliminary action identifies suitable materials in advance, reducing the need for frequent field testing and improving overall productivity by preventing premature wear failures.
