Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If visual assessment methods are used to monitor larval condition, then the system setup remains simple, but the measurement precision and automation level are insufficient
Solution Approach 1:
The patent replaces visual assessment methods with sensor-based detection systems that measure humidity and temperature. This substitution transitions from manual observation to automated physical measurement, significantly improving measurement precision while maintaining relatively simple device complexity through the use of basic sensor components.
Solution Approach 2:
The system enables self-service monitoring by automatically measuring larval condition parameters through humidity and temperature sensors. The sensors continuously collect data without requiring manual intervention, allowing the system to monitor itself and provide objective measurements of larval development stages.
2Productivity
If manual monitoring processes are used, then the device complexity is low, but the productivity and harvest yield are suboptimal
Solution Approach 1:
The patent implements feedback mechanisms where sensor data on humidity and temperature are continuously collected and used to determine optimal harvest timing. This feedback loop allows operators to make data-driven decisions about when larvae are ready for harvest, improving productivity and yield by preventing premature or delayed harvesting.
Solution Approach 2:
Manual monitoring processes are replaced with automated sensor-based systems that track environmental parameters. This substitution enables continuous monitoring without additional complex equipment, improving productivity through automated data collection and analysis while keeping the system relatively simple.
3Measurement precision
If optical detection devices are used to monitor larval activity, then measurement precision improves, but the device complexity and cost increase
Solution Approach 1:
The patent replaces optical detection devices with humidity and temperature sensors for monitoring larval activity. This substitution uses simpler, more cost-effective sensor technology that indirectly measures larval activity through environmental parameter changes, achieving sufficient measurement precision without the complexity and cost of optical systems.
Solution Approach 2:
The system uses environmental parameters (humidity and temperature) as intermediaries to detect larval activity. Instead of directly observing larvae with complex optical devices, the sensors measure changes in the environment caused by larval presence and activity, providing indirect but effective detection through simpler means.
