Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate lights are used to provide different light types and colors, then each light function can be provided reliably, but the device complexity and number of components increases
Solution Approach 1:
The patent combines multiple separate light sources (first light source, second light source, third light source) into a single integrated light system that shares common components including a single lens, housing, and control circuitry. This merging approach reduces the overall number of components while maintaining the ability to provide multiple distinct light functions (first light type, second light type, third light type) with different colors and characteristics.
Solution Approach 2:
The light system is designed as a multi-functional unit where a single device can provide multiple different light types and colors through selective activation of different light sources. The common lens and housing serve universal purposes for all light functions, while the control circuitry can selectively activate combinations of light sources to produce various lighting modes including first light function, second light function, and third light function.
2Device complexity
If a single lens is used for multiple light blades, then the device complexity is reduced, but the manufacturing precision and optical quality may deteriorate
Solution Approach 1:
The single lens is designed with different optical zones or regions that correspond to different light sources and light types. Each region of the lens is optimized for specific optical requirements of particular light blades, allowing the lens to maintain high optical quality for multiple different light functions while remaining a single component. The control circuitry selectively activates specific light sources to ensure optimal performance from relevant lens regions.
