Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual intervention is used to adjust light exposure, then flexibility in adjusting lighting is improved, but labor intensity increases and timing precision deteriorates
Solution Approach 1:
The system automatically determines light-on and light-off times based on temperature data without requiring manual intervention. The processor autonomously analyzes temperature patterns and generates control signals for the grow lights, eliminating the need for human operation while maintaining optimal lighting schedules
Solution Approach 2:
The patent replaces manual mechanical adjustment with an automated electronic control system. Temperature sensors and processors substitute for human decision-making, using algorithms to determine optimal lighting times based on environmental data, thereby eliminating labor-intensive manual operations
2Device complexity
If fixed lighting schedules are used, then system simplicity is improved, but adaptability to environmental changes deteriorates
Solution Approach 1:
The lighting schedule dynamically adjusts based on real-time temperature data rather than following a fixed timetable. The system continuously monitors environmental conditions and modifies light-on/light-off times accordingly, enabling adaptability while maintaining relatively simple system architecture through straightforward temperature-threshold-based control logic
Solution Approach 2:
The system uses temperature sensors to continuously monitor environmental conditions and feeds this information back to the processor. Based on this feedback, the system automatically adjusts lighting schedules to adapt to changing environmental conditions, bridging the gap between simplicity and adaptability through closed-loop control
3Productivity
If excessive light exposure is provided, then plant growth promotion is improved, but plant damage risk increases
Solution Approach 1:
The system optimizes lighting parameters (duration and timing) based on temperature conditions and plant growth requirements. By dynamically adjusting light exposure parameters rather than using fixed intensive lighting, the system promotes growth while avoiding overexposure damage through precise parameter control
Solution Approach 2:
Instead of providing continuous maximum light exposure, the system applies lighting partially and selectively during optimal time windows determined by temperature patterns. This partial action approach provides sufficient light for growth promotion while avoiding the harmful effects of excessive or prolonged illumination
