Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional artificial light cultivation methods are used, then productivity is maintained, but manufacturing precision of vegetable quality is poor
Solution Approach 1:
The patent applies parameter changes by systematically varying light wavelength, intensity, and duration parameters to achieve precise control over vegetable quality metrics. The system adjusts these optical parameters based on correspondence information linking light characteristics to quality outcomes, enabling precise manufacturing of desired vegetable qualities without excessive system complexity
Solution Approach 2:
The patent implements feedback mechanisms by measuring actual vegetable quality parameters and comparing them against target values. The system uses this feedback to adjust light irradiation parameters in subsequent cycles, progressively improving quality control precision while maintaining manageable system complexity through iterative optimization
2Manufacturing precision
If light irradiation parameters are increased to improve quality, then manufacturing precision improves, but productivity may decrease
Solution Approach 1:
The patent applies periodic action by implementing cyclic light irradiation patterns with specific durations and intervals. The system uses periodic measurement and adjustment cycles to maintain quality consistency while optimizing cultivation time, preventing productivity loss through efficient use of light exposure periods rather than continuous maximum irradiation
Solution Approach 2:
The patent implements dynamics by making light irradiation parameters adjustable and adaptable throughout the cultivation process. The system dynamically modifies wavelength, intensity, and duration based on plant growth stage and target quality requirements, enabling both high quality consistency and efficient productivity through optimized parameter sequences
