Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual adjustment is used to set the illumination angle, then the device complexity is reduced, but the manufacturing precision and adaptability deteriorate due to time-consuming and inaccurate positioning
Solution Approach 1:
The patent replaces manual mechanical adjustment with an electronically controlled adjustment unit that actuates the light source carrier. This substitution eliminates the need for manual positioning while achieving precise and reproducible illumination angles through electronic control mechanisms.
Solution Approach 2:
The patent implements electronic control of the light source carrier's position and orientation parameters. The adjustment unit can electronically modify angular positions and emission angles, enabling precise control that is reproducible and adaptable to different illumination requirements without manual intervention.
2Device complexity
If manual adjustment is used to set the illumination angle, then the device complexity is reduced, but the productivity deteriorates due to time-consuming adjustment processes
Solution Approach 1:
The patent replaces time-consuming manual adjustment with automated electronic control. The adjustment unit can be actuated by the control and interface unit to quickly position the light source carrier at desired angles, dramatically reducing setup time and improving productivity.
Solution Approach 2:
The patent enables preliminary programming of illumination angles and configurations. The control and interface unit can store and recall predetermined settings, allowing the system to be pre-configured for different applications without requiring manual re-adjustment each time.
3Device complexity
If the light source carrier is fixed in position, then the device complexity is reduced, but the adaptability deteriorates when wavelength or temperature changes cause illumination homogeneity to shift
Solution Approach 1:
The patent transforms the fixed light source carrier into a dynamically adjustable component. The adjustment unit can actively modify the carrier's position and orientation in response to changing conditions such as wavelength shifts or temperature variations, maintaining illumination homogeneity through adaptive repositioning.
Solution Approach 2:
The patent incorporates sensors that detect changes in illumination characteristics and provide feedback to the control and interface unit. This feedback mechanism enables the system to automatically adjust the light source carrier's position to compensate for wavelength or temperature-induced shifts, maintaining stable illumination homogeneity.
4Device complexity
If multiple beam lights are manually positioned, then the device complexity is reduced, but the manufacturing precision deteriorates as it is almost impossible to set multiple beams to identical angles
Solution Approach 1:
The patent employs a universal electronic control system that manages multiple light source carriers simultaneously. The control and interface unit can coordinate the adjustment of multiple beams, ensuring identical and consistent angles across all carriers through centralized electronic control rather than separate manual adjustments.
Solution Approach 2:
The patent replaces manual mechanical positioning of multiple beams with automated electronic control. The adjustment units for each light source carrier can be simultaneously actuated by the control and interface unit, ensuring precise and identical angular positioning across all beams without the variability inherent in manual operations.
