Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional luminaires use focusing and shading to adjust illumination angle, then light distribution can be modified, but the device complexity increases and luminous efficacy is lost
Solution Approach 1:
The luminaire divides the light source into multiple groups (first group, second group, third group) that can be independently controlled. Each group corresponds to a specific illumination angle, allowing the system to adjust the illumination angle by selecting which groups are activated rather than using complex mechanical adjustment mechanisms.
Solution Approach 2:
The system dynamically switches between different groups of lights based on control signals from the remote device or voice commands. This dynamic switching enables real-time adjustment of illumination angles without physical movement or mechanical components, reducing device complexity while maintaining adaptability.
2Adaptability or versatility
If conventional luminaires require manual rotation and stretching to adjust focal length, then illumination angle can be changed, but ease of operation deteriorates
Solution Approach 1:
The patent replaces manual mechanical adjustment (rotation, stretching) with electronic control systems. The control platform receives remote control signals or voice commands and automatically activates the appropriate groups of lights, eliminating the need for users to manually rotate or stretch components to adjust focal length and illumination angle.
Solution Approach 2:
The luminaire system automatically determines which groups of lights to activate based on received control signals. The system self-adjusts the illumination parameters without requiring user intervention in the physical adjustment process, improving ease of operation while maintaining adaptability.
3Adaptability or versatility
If conventional luminaires use shading to adjust illumination angle, then light distribution can be modified, but luminous efficacy is lost
Solution Approach 1:
Instead of using shading components that block and waste light, the system segments the light source into multiple controllable groups. Each group is directed at a specific angle, and the system achieves illumination angle control by selectively activating appropriate groups, thereby avoiding light blockage and minimizing luminous efficacy loss.
Solution Approach 2:
The system changes the operational parameters by activating different groups of lights with specific characteristics (different angles, intensities) rather than using physical shading. This parameter-based control method adjusts illumination angle while maximizing light utilization and minimizing energy loss.
4Ease of operation
If conventional luminaires lack remote and voice control, then device simplicity is maintained, but ease of operation deteriorates
Solution Approach 1:
The control platform is designed with multi-functionality, supporting both remote control signals and voice commands through the same system architecture. This universal control interface handles multiple input methods without requiring separate control systems, improving ease of operation while minimizing the increase in device complexity.
Solution Approach 2:
The control platform acts as an intermediary between the user (via remote device or voice) and the light source groups. It processes control signals and voice commands, translates them into appropriate group activation patterns, and manages the switching between different illumination configurations, thereby providing sophisticated control capabilities without exposing complexity to the user.
