Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dipped beam and high beam are designed separately or multiple optical units are used, then headlamp system can realize integrated design, but device complexity increases and manufacturing cost rises
Solution Approach 1:
The patent combines dipped beam and high beam functions into a single optical unit by using one LED light source with two independently controllable circuits. The LED emits light that is distributed to both dipped beam and high beam optical systems through a shared optical path, eliminating the need for separate optical units and reducing overall system complexity while maintaining functional integration
Solution Approach 2:
The single LED light source serves multiple functions by being controlled through different circuits - one circuit controls the LED for dipped beam operation while another circuit controls the same LED for high beam operation. This multi-functional approach allows one component to replace what would traditionally require separate components, simplifying the optical system structure
2Adaptability or versatility
If traditional light source headlamps use mechanical means for adaptive lighting, then beam direction can be adjusted, but the level of intelligence is insufficient and device complexity increases
Solution Approach 1:
The patent replaces mechanical adaptive lighting systems with an electronic control system. Instead of using mechanical means to adjust beam direction, the invention uses electronic circuits to independently control the LED light source, enabling adaptive lighting through electrical signals rather than mechanical movement. This substitution increases the intelligence level while reducing mechanical complexity
Solution Approach 2:
The patent implements dynamic control of the LED light source through separate control circuits that can independently adjust the LED's operation. The system can dynamically switch between dipped beam and high beam modes, and can also dynamically control the LED during turning operations to provide adaptive lighting that responds to real-time driving conditions without mechanical components
3Loss of energy
If LED light source is used with integrated dipped beam and high beam, then light utilization is improved and glare is reduced, but adaptability to different road environments is insufficient
Solution Approach 1:
The patent implements dynamic adaptability by providing separate control circuits for the LED light source that can independently adjust the LED's operation based on driving conditions. The system can dynamically switch between dipped beam and high beam modes, and can also dynamically control the LED during turning operations, enabling the integrated system to adapt to different road environments while maintaining high light utilization efficiency
Solution Approach 2:
The patent changes the operational parameters of the LED light source through different control circuits to achieve adaptability. By controlling the LED's intensity, duration, and activation patterns through separate circuits, the system can adjust its behavior to suit different road environments - such as controlling the LED for extended periods during turns or switching between beam modes - while maintaining the efficiency benefits of LED technology
