Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If artificial monochromatic light is used for vehicle interior lighting, then the lighting system is simple and reliable, but the lighting quality is poor and bothersome to passengers
Solution Approach 1:
The patent combines natural light and artificial light into a unified lighting system. The natural light guide module captures natural light from outside the vehicle, while the artificial light module provides supplemental illumination. Both light sources are integrated to work together, merging their advantages to provide high-quality illumination that is comfortable for passengers while maintaining system reliability.
Solution Approach 2:
The lighting system is designed to perform multiple functions: it can operate using natural light alone during daytime, artificial light alone during nighttime or cloudy conditions, or a combination of both. The controller automatically switches between these modes based on environmental conditions, making the system universal and adaptable to various lighting scenarios.
2Adaptability or versatility
If only artificial light is used for interior illumination, then the lighting system is simple to control, but it cannot adapt to various indoor situations and natural light changes
Solution Approach 1:
The controller receives feedback from sensors that detect the presence and intensity of natural light, as well as user preferences for different lighting modes. Based on this feedback, the controller automatically adjusts the lighting configuration - switching between natural light, artificial light, or combined modes - to adapt to various indoor situations such as daytime resting, nighttime sleeping, or indoor plant cultivation.
Solution Approach 2:
The lighting system is designed to be dynamic rather than static. The controller can switch between different lighting modes (natural light mode, artificial light mode, combined mode) based on real-time conditions. The system adapts its behavior dynamically in response to changing environmental conditions and user needs, providing versatile illumination for different indoor situations.
3Use of energy by moving object
If natural light is maximally utilized, then power consumption is reduced, but the lighting system becomes more complex requiring natural light condensers and transmitters
Solution Approach 1:
The natural light guide module acts as an intermediary between the external natural light source and the vehicle interior. It captures natural light through a lens, guides it via a light guide plate, and distributes it throughout the interior space. This intermediary structure enables efficient natural light utilization while maintaining a relatively simple and integrated system design.
Solution Approach 2:
The system is designed to maximize the use of free natural light from the environment, reducing reliance on energy-consuming artificial light sources. By capturing and distributing natural light automatically without requiring additional energy input, the system provides self-service illumination during daytime, significantly reducing power consumption.
4Adaptability or versatility
If brightness is selectively adjusted using dimming function, then user comfort is improved, but the system cannot control illumination based on various indoor situations
Solution Approach 1:
The controller uses feedback from user input (such as voice commands or button presses) to determine the desired lighting mode. Based on this feedback and the current environmental conditions, the controller selects and executes the appropriate lighting configuration - whether natural light mode, artificial light mode, or combined mode - providing situation-adaptive illumination control.

Data Source
AI summary
A structure and method for utilizing natural light indoors or in the interior in a moving space are disclosed. The method includes: determining, by a controller, whether or not current indoor information is confirmable; determining, by the controller, whether or not the current indoor information coincides with a user request signal, upon determining that the current indoor information is confirmable; controlling, by the controller, radiation amounts of the natural light and artificial light, upon determining that the current indoor information does not coincide with the user request signal; and adjusting, by the controller, a position value of a smart lamp unit.
