Engineering Contradiction Analysis
1Extent of automation
If conventional plant growing methods are used with human intervention, then plant growth can be monitored and managed, but labor costs increase and human intervention is required at every stage
Solution Approach 1:
The system divides plant growth management into distinct functional modules: watering device with soil moisture sensors, climate control system with temperature and humidity sensors, nutrient distribution system with pH and nutrient level sensors, lighting system with photoperiod control, and pest control system. Each module operates semi-autonomously based on sensor feedback, reducing overall system complexity while achieving high-level automation.
Solution Approach 2:
The controller integrates multiple functions into a single central unit that manages watering, climate control, lighting, nutrient distribution, and pest control. This multi-functional approach reduces the number of separate control systems needed, balancing automation extent with device complexity.
2Measurement precision
If more sensors and monitoring equipment are added to the system, then measurement precision improves, but device complexity increases
Solution Approach 1:
Sensors are strategically placed at specific locations where they provide maximum measurement value: soil moisture sensors near plant roots, temperature and humidity sensors at plant canopy level, pH sensors in the nutrient solution, and light sensors near the growth area. This localized sensor deployment achieves high measurement precision without requiring sensors throughout the entire system, thus controlling complexity.
3Productivity
If autonomous control systems are implemented, then labor costs decrease, but system complexity and initial investment increase
Solution Approach 1:
The system implements continuous feedback loops where sensors monitor plant growth conditions (soil moisture, temperature, humidity, pH, light intensity) and automatically adjust control parameters through the controller. This feedback mechanism enables autonomous operation that improves productivity while keeping the control system relatively simple by using straightforward sensor-actuator relationships rather than complex algorithms.
Solution Approach 2:
The plant growth system monitors and adjusts its own operating conditions without external intervention. The controller automatically activates watering when soil moisture drops, adjusts lighting when photoperiod requirements change, regulates climate when temperature or humidity deviate from setpoints, and manages nutrient distribution based on plant needs. This self-service capability increases productivity while maintaining manageable system complexity through rule-based automation.
