Inclined Body and Screen Rails for Windscreen Adjuster Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Straddled vehicles face limitations in windscreen adjuster design, where a large movable range of the windscreen interferes with surrounding components, reducing the degree of freedom in layout.
Innovation Solution
The windscreen adjuster is configured with inclined body and screen rails, allowing the sliders to move along both types of rails, dividing the rail length and improving layout flexibility while maintaining a large movable range, and optionally incorporating diffusers that move without additional power sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the rail length is increased to widen the movable range of the windscreen, then the movable range is improved, but the rail interferes with surrounding parts and layout freedom is reduced
Solution Approach 1:
The patent divides the single long rail into two separate rails: a body rail attached to the vehicle body and a screen rail attached to the windscreen. This segmentation allows each rail to be shorter individually while collectively providing the same or greater movable range, thereby reducing interference with surrounding parts and improving layout freedom.
2Length of moving object
If the rail length is increased to widen the movable range of the windscreen, then the movable range is improved, but the size of the windscreen adjuster increases
Solution Approach 1:
By segmenting the adjuster mechanism into two separate rails (body rail and screen rail) with sliders connecting them, the patent reduces the overall size of the adjuster assembly. Each component can be optimized independently, and the segmented structure allows for more compact arrangement within the vehicle constraints.
Solution Approach 2:
The patent introduces inclination angles for both the body rail and screen rail relative to the vertical direction. This dimensional change allows the rails to utilize space more efficiently in three-dimensional space, achieving the required movable range without increasing the adjuster's footprint or volume.

AI summary
The left and right body rails are inclined so that the distance between the upper ends of the left and right body rails in the vehicle width direction is different from the distance between the lower ends of the left and right body rails in the vehicle width direction as seen in the vehicle front view. The left and right screen rails are inclined so that the distance between the upper ends of the left and right screen rails in the vehicle width direction is different from the distance between the lower ends of the left and right screen rails in the vehicle width direction as seen in the vehicle front view. The left and right screen rails are inclined in the direction opposite to the left and right body rails as seen in the vehicle front view.
