Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the brightness of the lamp is increased to improve illumination, then the illumination intensity is improved, but the power consumption increases
Solution Approach 1:
The lamp system dynamically adjusts the brightness of the light source based on real-time illuminance sensor data and vehicle operating conditions. The processor continuously monitors environmental lighting conditions and modifies the light output accordingly, transitioning from static to dynamic control to optimize the balance between illumination intensity and power consumption.
Solution Approach 2:
The system changes the operating parameters of the light source by adjusting the driving current and brightness levels based on measured illuminance conditions. When ambient light is sufficient, the system reduces the light output parameter; when ambient light is insufficient, it increases the output, thereby adapting the illumination intensity to actual needs and reducing unnecessary power consumption.
2Illumination intensity
If the light output is continuously maintained at high level to ensure visibility, then the illumination intensity is improved, but the power consumption increases
Solution Approach 1:
The system employs illuminance sensors to continuously monitor ambient lighting conditions and feeds this information back to the processor. Based on the feedback signal, the processor automatically adjusts the light source output, creating a closed-loop control system that maintains adequate illumination while minimizing power consumption by avoiding continuous high-level output.
Solution Approach 2:
The lamp system serves itself by using onboard sensors and processors to autonomously determine the appropriate light output level. The system self-adjusts based on environmental conditions without requiring manual intervention, thereby optimizing power consumption while maintaining necessary illumination intensity.
3Use of energy by moving object
If the lamp structure is improved to reduce power consumption, then the power consumption is reduced, but the material cost increases
Solution Approach 1:
The existing lamp structure is enhanced by integrating multi-functional components: illuminance sensors that also serve as environmental monitoring devices, and a processor that manages both lighting control and power optimization. This multi-functionality approach reduces the need for separate specialized components, thereby controlling material costs while achieving power consumption reduction through intelligent control.
Solution Approach 2:
The patent replaces mechanical or structural improvements with an electronic control system. Instead of modifying the physical lamp structure to reduce power consumption, the system uses electronic sensors and processors to intelligently control light output, substituting mechanical complexity with electronic intelligence and thereby avoiding increased material costs.
4Use of energy by moving object
If the brightness is dynamically adjusted based on environmental conditions, then the power consumption is reduced, but the device complexity increases
Solution Approach 1:
The patent merges the illuminance sensing function, processing function, and light source control function into an integrated system. The processor combines multiple control algorithms (illuminance-based adjustment, vehicle state consideration, and power management) into a single control unit, reducing the need for separate independent components and thereby managing device complexity while achieving dynamic brightness adjustment and power consumption reduction.
