Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional lighting devices are used, then they provide basic illumination, but they lack flexibility in adjusting light output and distribution
Solution Approach 1:
The patent implements a rotatable light source module that can dynamically adjust the direction of light emission. The module rotates around a vertical axis, allowing the main light emission direction to be changed from downward to oblique or upward angles, providing dynamic adaptability to different lighting scenarios without requiring multiple fixed lighting devices
Solution Approach 2:
The lighting device integrates multiple functions into a single unit: it provides both downward illumination for work surfaces and upward illumination for ambient lighting or wall washing. The rotatable module allows the same light source to serve multiple lighting purposes by changing its orientation, reducing the need for separate lighting fixtures for different functions
2Adaptability or versatility
If fixed lighting direction is used, then the structure is simple, but it cannot be adjusted to different surfaces and environments
Solution Approach 1:
The light source module is designed to rotate around a vertical axis, enabling continuous adjustment of the light beam direction. This dynamic positioning capability allows users to adapt the lighting to different surfaces and environments by simply rotating the module to the desired angle, making the adjustment process intuitive and operationally simple
3Loss of energy
If LED lighting is used, then energy consumption is reduced, but the initial cost is high
Solution Approach 1:
The lighting device uses multiple individual LED modules arranged in an array, with each module containing LEDs of different colors (red, green, blue, yellow). This segmentation allows for flexible configuration and potential use of smaller, more cost-effective LED components while maintaining energy efficiency through the combined output of multiple lower-power modules
