Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional methods are used to detect sugar content, then the detection process is complex and inconvenient, but the patent achieves convenient and accurate detection through a simple resistance measurement approach
Solution Approach 1:
The patent replaces complex chemical analysis methods with a simple electrical resistance measurement system. By inserting two electrodes into the fruit or vegetable and measuring the resistance between them, the system determines sugar content based on the correlation between resistance values and sugar concentration, achieving both convenience and accuracy without complex mechanical or chemical procedures
Solution Approach 2:
The patent changes the measurement parameter from complex chemical composition analysis to simple electrical resistance measurement. The resistance of the fruit or vegetable tissue varies with sugar content, and by measuring this resistance parameter through the electrode system, the patent achieves accurate sugar content detection through a convenient electrical measurement approach
2Reliability
If no detection device is used, then the device complexity is low, but the ability to detect and monitor sugar content is insufficient
Solution Approach 1:
The detection system is segmented into simple, independent functional modules: two measurement electrodes for electrical contact, a resistance detection circuit for measuring resistance, and a processor for calculating sugar content from the resistance value. This segmentation achieves reliable detection capability while keeping each component simple and the overall device complexity low
Solution Approach 2:
The patent introduces an intermediary resistance measurement as a mediator between the fruit/vegetable sample and the sugar content determination. Instead of directly analyzing sugar content, the system measures the electrical resistance of the tissue, which serves as an intermediary parameter that correlates with sugar content, simplifying the detection process while maintaining reliability
