Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed delay time is used for sorting processing, then the device operation is simple, but the sorting accuracy deteriorates due to varied particle forms and sizes
Solution Approach 1:
The patent applies dynamics by making the delay time variable rather than fixed. The delay time is dynamically adjusted based on the detected particle size, allowing the system to adapt to different particle forms and sizes while maintaining accurate sorting timing
Solution Approach 2:
The patent changes the parameter of delay time based on particle size detection. By establishing a relationship between particle size and optimal delay time, the system adjusts the timing parameter to match the specific particle being sorted, resolving the contradiction between operational simplicity and sorting accuracy
2Manufacturing precision
If the delay time is adjusted for each particle size, then the sorting accuracy is improved, but the device complexity increases
Solution Approach 1:
The system performs self-adjustment by automatically determining the appropriate delay time based on detected particle size. The processing unit autonomously calculates and applies the correct delay time without requiring manual intervention or complex external control mechanisms
Solution Approach 2:
The patent replaces complex mechanical timing adjustment mechanisms with computational processing. The processing unit uses algorithms to determine delay time based on particle size detection results, substituting mechanical complexity with software-based intelligence
3Productivity
If the delay time is not accurately controlled, then the sorting processing is fast, but the sorting precision deteriorates
Solution Approach 1:
The system performs preliminary detection of particle size and pre-calculates the appropriate delay time before sorting execution. This preliminary action allows the system to prepare the optimal timing in advance, ensuring both fast execution and high precision during the actual sorting process
