Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple independent light sources are used in complex hardware systems, then each device can emit light independently, but the space occupation and heat dissipation requirements increase significantly
Solution Approach 1:
The patent merges multiple independent light sources into a single centralized light source that serves multiple devices. The centralized light source emits light that is then distributed to various devices through optical waveguides, reducing the total number of light sources from N (one per device) to 1 (shared by all devices), thereby significantly reducing space occupation while maintaining independent light emission capability for each device
Solution Approach 2:
The centralized light source performs multiple functions by serving as the light source for multiple different devices simultaneously. Instead of each device having its own dedicated light source, the single centralized light source is universally utilized across the system, with light being routed to different devices as needed through the optical waveguide network
2Reliability
If multiple independent light sources are used in complex hardware systems, then each device can emit light independently, but the heat dissipation requirements increase substantially
Solution Approach 1:
By combining multiple light sources into one centralized unit, the patent consolidates the heat generation points from N separate sources into a single heat source. This allows for more efficient heat management and dissipation, as the thermal load is concentrated in one location rather than distributed across multiple devices, reducing overall heat dissipation requirements while maintaining independent light emission capability
3Area of stationary object
If a centralized light source is used to provide light energy to multiple devices, then the number of light sources is reduced and space is saved, but the light allocation must be dynamically adjusted to meet different device requirements
Solution Approach 1:
The patent introduces optical waveguides as intermediary components that facilitate the distribution of light from the centralized light source to multiple devices. The waveguides act as mediators that can dynamically route and allocate light to different devices based on their specific requirements, managing the complexity of light allocation while maintaining the space benefits of a centralized source
Solution Approach 2:
The system implements dynamic light allocation where the centralized light source and optical waveguides can adjust light distribution in real-time based on the specific needs of different devices. This dynamic capability allows the system to adapt to varying light requirements of different devices while maintaining a compact centralized architecture, balancing space savings with allocation flexibility

AI summary
A method may be applied to a vehicle. The vehicle includes at least two devices to emit light that provide light energy by using a centralized light source, and each of the devices to emit light is connected to the centralized light source by using an optical waveguide. A control device in the vehicle may obtain a light-emitting instruction, where the light-emitting instruction carries information about a first optical power required by one target device to emit light of the at least two devices to emit light, or information about a first optical power required by each of a plurality of target devices to emit light; and allocate, based on the information about the first optical power, light emitted by the centralized light source, so that each target device to emit light obtains respective corresponding light by using the optical waveguide.
