Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If horticultural light sources operate at high power to meet illumination requirements, then plant growth needs are satisfied, but rapid voltage changes and flickers occur in the electrical grid
Solution Approach 1:
The system dynamically adjusts the power consumption of horticultural light sources based on real-time detection of grid conditions and illumination requirements. The event detection module continuously monitors power usage patterns and sends illumination instructions to modify power consumption, creating a dynamic balance between maintaining adequate plant illumination and preventing harmful electrical grid effects.
Solution Approach 2:
The system changes operational parameters of the horticultural light sources by sending illumination instructions that adjust power consumption levels. The event detection module detects events affecting illumination conditions and modifies power usage parameters to eliminate rapid voltage changes and flickers while maintaining sufficient light output for plant growth.
2Use of energy by moving object
If the power usage of horticultural light sources is increased to ensure adequate illumination, then plant growth requirements are met, but negative impacts on the electrical grid increase
Solution Approach 1:
The system implements a feedback mechanism where the event detection module continuously monitors power usage of horticultural light sources and detects events that may cause harmful effects. Based on this feedback, the system sends illumination instructions to adjust power consumption, creating a closed-loop control system that balances energy usage with grid stability.
Solution Approach 2:
The event detection module detects events affecting illumination conditions before they cause harmful effects on the electrical grid. By identifying power usage patterns and potential issues in advance, the system can send illumination instructions to adjust power consumption proactively, preventing rapid voltage changes and flickers before they occur.
3Productivity
If horticultural light sources vary their power consumption to adapt to illumination conditions, then energy efficiency improves, but electrical grid stability deteriorates
Solution Approach 1:
The system uses feedback from the event detection module to monitor both illumination conditions and power consumption patterns. This feedback enables the system to adjust power usage in a controlled manner that maintains energy efficiency while preventing harmful variations that would compromise electrical grid stability.
Solution Approach 2:
The event detection module detects events and analyzes power usage evolution before harmful effects occur. By taking preliminary action to adjust illumination instructions, the system can vary power consumption adaptively while maintaining grid stability, as the adjustments are made proactively rather than reactively to unstable conditions.

AI summary
The present techniques generally concern methods and systems for managing undesired effects in an electrical grid, which may include rapid voltage change(s) and/or flicker(s). The system includes an event detection module operatively connected to a plurality of horticultural light sources. The event detection module is configured to determine a power usage of the horticultural light sources, based on illumination conditions, detect an event affecting the illumination conditions, determine whether the event causes the undesired effects in the electrical grid, based on an evolution of the power usage of the horticultural light sources in response to the event, and send illumination instructions to the horticultural light sources to adjust the power usage of the horticultural light sources, if the event causes the undesired effects.
