Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional monitoring methods are used for screening material handling, then device complexity is reduced, but reliability deteriorates due to undetected operational problems
Solution Approach 1:
The patent replaces complex mechanical monitoring systems with ultrasonic detection technology. The ultrasonic transmitter and receiver detect material properties, build-up, and operational status through acoustic waves, eliminating the need for complex mechanical sensors and direct contact monitoring devices while improving reliability.
Solution Approach 2:
The ultrasonic waves serve as an intermediary between the monitoring system and the screening material. Instead of direct mechanical contact or complex electrical sensors, the system uses acoustic waves to indirectly detect material properties, screen condition, and operational parameters, simplifying the overall system architecture.
2Loss of information
If no detection system is installed, then device complexity remains low, but loss of information about operational status increases
Solution Approach 1:
The system uses ultrasonic detection instead of complex electrical or mechanical sensors to obtain operational information. The ultrasonic transmitter and receiver provide comprehensive material and system status data through acoustic properties, reducing information loss while keeping the system relatively simple.
Solution Approach 2:
The ultrasonic detection system performs multiple functions simultaneously: detecting material properties (size, density, moisture), monitoring screen condition (build-up, wear), and identifying operational issues (jams, blockages). This multi-functionality reduces information loss across multiple parameters without proportionally increasing system complexity.
3Measurement precision
If manual inspection methods are used, then manufacturing precision of detection systems is reduced, but measurement precision of material parameters deteriorates
Solution Approach 1:
The patent replaces manual inspection with automated ultrasonic detection. The ultrasonic transmitter and receiver precisely measure material parameters such as size, density, and moisture content through acoustic wave interactions, achieving high measurement precision without the subjectivity and error associated with manual methods.
Solution Approach 2:
The ultrasonic detection system automatically measures and monitors material parameters without human intervention. The control unit processes ultrasonic signal data to continuously provide precise measurements of material properties and operational status, eliminating the need for manual measurement tools and personnel while maintaining high precision.
