Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If LED lighting fixtures are mounted and oriented to achieve desired light output, then illumination quality is improved, but the fixtures become susceptible to misalignment from environmental factors such as wind and physical interactions
Solution Approach 1:
The patent employs sensors to continuously monitor the orientation and position of LED lighting fixtures, feeding this data back to a control system that automatically adjusts the fixture orientation to maintain proper alignment despite environmental disturbances such as wind or physical impacts
Solution Approach 2:
The system enables self-correction of misaligned fixtures through automated control mechanisms that detect alignment deviations and independently adjust the fixture orientation without requiring manual intervention, allowing the lighting system to maintain optimal performance autonomously
2Illumination intensity
If manual aiming of light fixtures is performed to achieve even lighting, then illumination uniformity is improved, but the process becomes complex and difficult for casual observers to execute precisely
Solution Approach 1:
The patent replaces manual mechanical aiming processes with an automated electronic system that uses sensors to detect light distribution patterns and a control system to automatically adjust fixture orientation, eliminating the need for complex manual calculations and observations of isocandela curves
Solution Approach 2:
The system introduces sensors and control algorithms as intermediaries between the light fixture and the mounting structure, enabling precise alignment through automated feedback loops rather than direct manual observation and adjustment of light patterns
3Measurement precision
If automated orientation correction is implemented, then alignment precision is improved, but device complexity increases due to additional sensors and control systems
Solution Approach 1:
The patent integrates multiple functions into the control system, including orientation sensing, alignment calculation, and actuation control, within a single unified platform that manages both the monitoring and correction of fixture alignment, reducing overall system complexity despite the added capabilities
