Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional LED lighting systems use fixed LED arrays, then the structure is simple and easy to manufacture, but the light distribution and intensity control are limited
Solution Approach 1:
The patent implements adjustable support surfaces that can change angles, allowing LED arrays to be repositioned dynamically. This enables the light distribution and intensity to be adjusted according to different application requirements, resolving the contradiction between fixed structure simplicity and light control versatility
Solution Approach 2:
The lighting system is divided into multiple independent LED arrays mounted on separate adjustable support surfaces. Each array can be independently positioned and controlled, allowing flexible light distribution while maintaining a modular structure that doesn't excessively increase complexity
2Adaptability or versatility
If conventional LED lighting systems lack independent dimming control, then the device complexity is low, but the intensity control flexibility is insufficient
Solution Approach 1:
The control system is segmented into multiple independent LED driver circuits, each controlling a specific LED array or group. This allows independent dimming control of different lighting zones while maintaining a manageable control architecture that doesn't overly complicate the system
Solution Approach 2:
Different regions of the lighting system can have different control characteristics through locally assigned driver circuits. Each zone can be independently dimmed according to specific requirements, providing intensity control flexibility without requiring a monolithic complex control system
3Adaptability or versatility
If LED arrays are positioned at fixed angles, then the manufacturing precision requirements are lower, but the light distribution optimization capability is reduced
Solution Approach 1:
Instead of requiring precise fixed positioning during manufacturing, the support surfaces are designed to be adjustable after assembly. This allows the LED arrays to be positioned at optimal angles in the field, reducing manufacturing precision requirements while maintaining light distribution optimization capability
Solution Approach 2:
The adjustable support surfaces are pre-configured with mounting mechanisms that facilitate easy positioning and locking at various angles. This preliminary preparation enables precise positioning during installation without requiring extremely tight manufacturing tolerances
