Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If optical sensors are used for waste detection, then material identification capability is improved, but the sensors quickly become dirty and malfunction in waste-affected environments
Solution Approach 1:
The patent replaces optical sensors with radar technology, substituting an optical detection system with an electromagnetic wave-based system. Radar waves can penetrate through dust and debris without becoming contaminated, thereby maintaining measurement precision while eliminating the reliability issues associated with optical sensors in dirty environments.
Solution Approach 2:
The patent introduces radar waves as an intermediary detection medium that interacts with waste materials through electromagnetic reflection and absorption properties. This intermediary approach allows material identification without direct contact between the detection device and the waste, preventing contamination and maintaining system reliability.
2Measurement precision
If barcode markers are applied to each waste item for sorting, then sorting accuracy is improved, but the cost increases due to marker application requirements
Solution Approach 1:
The patent extracts the detection function from the waste items themselves by using radar to detect intrinsic material properties directly. Instead of requiring external markers to be attached to each item, the system extracts material identification information from the waste items' natural electromagnetic characteristics, eliminating the need for costly marker application while maintaining sorting accuracy.
Solution Approach 2:
The waste items serve themselves by providing material identification information through their inherent electromagnetic properties. The radar system detects these natural properties without requiring any modification or additional components on the waste items, making the system cost-effective while maintaining high sorting accuracy.
3Adaptability or versatility
If radar waves are used for material detection, then detection capability without markers is improved, but system complexity increases due to transmitter/receiver devices and signal processing requirements
Solution Approach 1:
The radar system serves multiple functions: it detects material composition, determines waste volume, identifies unauthorized materials, and provides sorting information all through a single transmitter/receiver setup. This multi-functionality reduces overall system complexity compared to having separate systems for each detection task, while maintaining high adaptability across different waste types.
