Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional lighting systems are installed for retrofit applications, then lighting coverage is achieved, but wiring and power expenses increase significantly
Solution Approach 1:
The system divides the lighting installation into modular fixtures that can be independently installed and managed. Each fixture operates as a separate controllable unit, allowing selective powering and reducing overall power expenses while maintaining lighting coverage.
Solution Approach 2:
The lighting system implements dynamic control through sensors and controllers that adjust lighting operation based on real-time conditions such as occupancy and ambient light levels, optimizing power consumption while maintaining adequate illumination.
2Adaptability or versatility
If conventional lighting systems are used, then basic lighting function is provided, but adaptability to different environments and electricity pricing models is limited
Solution Approach 1:
The lighting fixtures incorporate multiple functions including LED lighting, ambient light sensing, occupancy sensing, and wireless communication capabilities within a single integrated unit, enabling adaptability to various environments without proportionally increasing system complexity.
Solution Approach 2:
The system automatically adapts to environmental conditions through integrated sensors that detect ambient light levels and occupancy, allowing the lighting to self-regulate without requiring complex external control systems or manual configuration for different environments.
3Reliability
If low-tech occupancy or ambient light sensors are used, then basic sensing function is achieved, but performance under varying environmental conditions deteriorates
Solution Approach 1:
The system continuously monitors environmental conditions through sensors and uses this feedback to dynamically adjust lighting operation, compensating for environmental variations and maintaining reliable sensing performance across different conditions.
Solution Approach 2:
The system adjusts its sensing and lighting parameters based on environmental conditions, such as modifying sensitivity thresholds or operational modes in response to changes in ambient light levels, temperature, or occupancy patterns, thereby maintaining reliability under varying environmental factors.
