Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If LED lighting lamps are used for basic illumination, then energy efficiency is improved, but light sensing and timing functions are lost, resulting in low intelligence and performance-to-price ratio
Solution Approach 1:
The patent combines multiple functions (illumination control, light sensing, timing, and high-voltage switching) into a single integrated control box. The control circuit board integrates the MCU, relay control, and switching mechanisms, allowing the system to perform automated light sensing and timing operations while maintaining a compact structure that does not significantly increase overall device complexity.
Solution Approach 2:
The patent introduces a control box as an intermediary device between the power source and the LED lamp strings. This control box contains the intelligence (MCU) and switching mechanisms (relays), allowing the LED lamps themselves to remain simple illumination elements while the control box provides the automated sensing and timing functions through its integrated circuitry.
2Loss of energy
If manual control of lamp strings is implemented, then device simplicity is maintained, but power consumption increases and intelligence is reduced
Solution Approach 1:
The control box is designed to operate autonomously using a photodetector for light sensing and an internal timer for timing operations. The system automatically detects ambient light levels and controls the lamp strings accordingly, eliminating the need for manual user intervention. This self-service capability reduces energy consumption by avoiding continuous manual control operations and optimizes power usage based on actual lighting conditions.
3Adaptability or versatility
If high voltage control is implemented for multiple lamp strings, then control capability is improved, but circuit complexity and safety risks increase
Solution Approach 1:
The patent uses relays to segment the high-voltage control circuit into isolated switching paths for different lamp strings. Each relay acts as an independent switch that can control specific lamp strings without affecting others, allowing versatile multi-string control while maintaining electrical isolation that enhances safety. The segmentation also allows the control circuit to manage multiple high-voltage loads through separate, controlled pathways.
