Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If lighting systems use fixed light color, intensity, and temperature, then the system structure is simple, but the system cannot dynamically create varied environments that influence human feelings and moods
Solution Approach 1:
The lighting system dynamically adjusts light color, intensity, and temperature based on different usage scenarios and environmental conditions. The controller modulates LED output in real-time to create varied lighting environments that adapt to human needs, transforming a static system into a dynamic one that responds to changing conditions.
Solution Approach 2:
The lighting system is designed to perform multiple functions including general illumination, mood setting, plant growth support, and air purification. By integrating diverse functionalities into a single system with a unified controller, the patent achieves versatility without proportionally increasing complexity.
2Adaptability or versatility
If lighting systems lack environmental sensing integration, then the system structure is simple, but the system cannot optimize lighting conditions for multiple functions based on humidity, temperature, and other parameters
Solution Approach 1:
The patent merges lighting functions with environmental sensing and air purification functions into an integrated system. The controller coordinates multiple subsystems (LED modules, sensors, purifiers) to work together, enabling the system to optimize lighting conditions based on real-time environmental data while maintaining manageable complexity through unified control.
Solution Approach 2:
Environmental sensors continuously monitor conditions such as humidity, temperature, and air quality, providing feedback to the controller. The controller uses this feedback to automatically adjust lighting parameters and purification operations, creating a closed-loop system that optimizes performance based on actual environmental conditions.
3Adaptability or versatility
If the system uses multiple light sources with different wavelengths, then the lighting functionality is enhanced, but the control complexity increases
Solution Approach 1:
The lighting system is divided into multiple independent LED modules, each emitting specific wavelengths (red, blue, green, yellow, orange). Each module can be controlled individually or in combination, allowing flexible light quality modulation without requiring a single complex control mechanism for all wavelengths.
Solution Approach 2:
The system modulates light output by changing the intensity parameters of individual wavelength sources rather than using physically different light sources. The controller adjusts the electrical current or PWM duty cycle for each LED module to achieve desired light quality, simplifying control compared to mechanical switching of separate light sources.
