Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If moving parts and multiple optical systems are used to generate different light beams, then the headlamp can produce dipped beam and daytime lamp functions, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines multiple optical functions (dipped beam and daytime lamp) into a single integrated reflector structure. The reflector has a first optical surface for dipped beam and a second optical surface for daytime lamp, both sharing common light sources and mounting structure, thereby reducing device complexity while maintaining versatility
Solution Approach 2:
The reflector structure serves multiple functions simultaneously - it acts as both a dipped beam reflector and a daytime lamp reflector. The light sources and mounting structure are universally used for both functions, eliminating the need for separate optical systems and reducing overall complexity
2Adaptability or versatility
If moving parts are used to adjust optical system position, then different light beam patterns can be achieved, but manufacturing cost increases
Solution Approach 1:
The patent provides for adjustable positioning of the reflector relative to the light sources through fastening means, allowing dynamic adjustment of optical alignment. This enables different light beam patterns without requiring complex moving parts, balancing versatility with manufacturing simplicity
Solution Approach 2:
The invention achieves different light beam patterns by changing the positional parameters of the reflector and light sources relative to each other. By adjusting the distance and alignment through fastening means, the optical system can produce dipped beam, daytime lamp, and other patterns without mechanical complexity
