Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In leaning and straddled vehicles, the integration of a laser beam source with multiple laser elements and drive circuits leads to increased size, making it difficult to efficiently use equipment installation space without compromising the vehicle's maneuverability and agility.
Innovation Solution
Implementing a shared driver circuit for multiple laser elements, with laser light-emission-manner converters positioned downstream of the most upstream branch portion in the laser beam path, allowing the laser beam source to be downsized and efficiently installed, while maintaining different light-emission manners for various light-emitting parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple laser elements and drive circuits are integrated into a single laser beam source to enable different light-emission manners, then the functionality and versatility of the lighting system is improved, but the size of the laser beam source increases
Solution Approach 1:
The patent divides the laser beam source into separate functional modules: multiple laser elements are spatially separated and each is driven by its own drive circuit. This segmentation allows each module to be optimized independently, reducing the overall volume while maintaining the capability to produce different light-emission manners through coordinated control of the separated elements.
Solution Approach 2:
The patent arranges multiple laser elements and their drive circuits in a distributed three-dimensional configuration rather than integrating them into a single compact unit. By utilizing spatial distribution across different locations, the system achieves multiple light-emission modes without requiring a large centralized volume, effectively transitioning from a two-dimensional integration problem to a three-dimensional spatial arrangement.
2Stability of the object's composition
If the laser beam source is positioned closer to the center of gravity to centralize vehicle mass, then the vehicle's dynamic balance is improved, but the equipment installation space becomes more constrained
Solution Approach 1:
By segmenting the laser elements and drive circuits into separate modules, the patent enables flexible placement of these components in distributed locations near the center of gravity. This segmentation allows the system to achieve mass centralization for improved dynamic balance while each module occupies only a small portion of the available equipment space, avoiding the need for a large centralized installation area.
Solution Approach 2:
The patent designs the laser elements and drive circuits as universal modular components that can be installed in various locations around the center of gravity. These modular units can be positioned to optimize both the vehicle's mass distribution and the available equipment installation space, allowing the same component design to serve multiple installation configurations.
3Volume of moving object
If components are densely arranged below the fuel tank or seat to maximize space utilization, then the vehicle's compactness is improved, but the degree of freedom in component arrangement is reduced
Solution Approach 1:
The patent segments the lighting system into multiple independent laser elements and drive circuits that can be densely arranged in available spaces below the fuel tank or seat. Each segmented module can be independently positioned, maintaining high arrangement flexibility despite the dense packing, as each module can be routed and connected through flexible pathways.
Solution Approach 2:
The patent employs dynamic routing and positioning capabilities for the segmented laser modules, allowing their arrangement to be optimized based on specific installation requirements. The modular design enables the system to adapt its configuration within the constrained space, maintaining degree of freedom in arrangement by allowing flexible repositioning and reconfiguration of individual modules as needed.

AI summary
A vehicle having: a vehicle body; a plurality of light-emitting parts; a light source configured to output a laser beam to the light-emitting parts; a fiber optic cable that constitutes a part of a laser beam path, the fiber optic cable having a most upstream branch portion; a single shared laser driver board controlling laser beam source elements in the single light source; and at least one laser light-emission-manner converter, each disposed in, or downstream of, the most upstream branch portion, to thereby cause each light-emitting part downstream from said each light-emission-manner converter to change a light-emission manner thereof. The laser light-emission-manner converter and/or the single shared laser driver board are at least partially disposed in an in-body covered region, which is disposed further downward than, and in a plan view of the vehicle overlaps, any of a fuel tank, a dummy tank, a foot board, and a seat.
