Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional rotating lighting modules are used to provide multiple optical functions, then the lighting device can achieve different light distributions, but the construction becomes complex and production cost increases
Solution Approach 1:
The lighting module is divided into functionally independent segments: a fixed light source unit and a rotating reflector unit. This segmentation allows each component to be optimized independently, simplifying construction while maintaining multiple optical functions through their coordinated operation.
Solution Approach 2:
The rotating reflector is designed with multiple reflective surfaces that can be selectively positioned to perform different optical functions. A single rotating component replaces what would traditionally require multiple fixed optical elements, reducing construction complexity while providing versatility.
2Adaptability or versatility
If traditional rotating lighting modules are used to provide multiple optical functions, then the lighting device can achieve different light distributions, but production cost increases
Solution Approach 1:
Multiple optical functions are merged into a single rotating reflector component rather than requiring separate optical elements for each function. This consolidation reduces the number of parts that need to be manufactured and assembled, thereby lowering production costs while maintaining functional versatility.
Solution Approach 2:
The rotating reflector serves multiple optical functions simultaneously, acting as a universal component that replaces what would traditionally require several different optical elements, thus reducing overall production cost.
3Device complexity
If traditional lighting modules are used, then the structure is simple, but they cannot generate animated welcome light distribution
Solution Approach 1:
The reflector is designed to rotate dynamically between different positions, enabling animated light distribution patterns for welcome functions. This dynamic capability is achieved through a simple rotational mechanism rather than complex multi-component systems, maintaining construction simplicity while adding functional versatility.
Solution Approach 2:
The system changes the orientation parameter of the reflector to generate different light distributions. By varying the reflector's angular position, the system can produce both normal lighting functions and animated welcome effects using the same basic structure.
4Device complexity
If the light source is fixed with respect to the reflector, then the structure is simple, but the light distribution cannot be dynamically changed
Solution Approach 1:
While the light source remains fixed relative to the housing, the reflector is made dynamic through its rotational capability. This creates a simple yet effective system where the relative position between light source and reflector changes during operation, enabling dynamic light distribution control without complicating the overall structure.
