Work Vehicle Cab Window and Brim Alignment for Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Work vehicles often lack adequate operator visibility and protection from vertically falling objects, which can compromise safety and efficiency during operations.
Innovation Solution
A work vehicle design featuring a cab structure with a brim and window alignment for enhanced visibility, where the window is positioned above the operating viewing position and protected by a cover that allows light passage through viewing openings, effectively safeguarding against vertically falling objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a traditional cab structure is used, then the structure is simple and easy to manufacture, but operator visibility is inadequate
Solution Approach 1:
The cab structure is segmented into multiple functional components: a brim with viewing openings, a window positioned above the operating viewing position, and protective covers. This segmentation allows each component to contribute to visibility while maintaining manufacturing simplicity through modular assembly.
Solution Approach 2:
The viewing system extends into the vertical dimension by positioning the window above the operating viewing position and incorporating a brim with viewing openings. This multi-level arrangement increases the total viewing area without significantly complicating the overall cab structure.
2Area of moving object
If the window is positioned to maximize visibility, then operator visibility is improved, but the window becomes vulnerable to vertically falling objects
Solution Approach 1:
A protective cover is provided that can be positioned over the window before falling objects reach it. The cover is configured to protect the window from vertically falling objects while allowing light to pass through viewing openings in the brim, thus preserving visibility while providing protection.
Solution Approach 2:
The protective cover acts as an intermediary element between the window and falling objects. It is positioned to intercept vertically falling objects before they can damage the window, while its design with viewing openings allows it to serve as a mediator that maintains the light path for operator visibility.
3Object-affected harmful factors
If a protective cover is added to safeguard the window, then protection from falling objects is improved, but light transmission may be obstructed
Solution Approach 1:
The protective cover is designed with non-uniform properties: it provides solid protection in areas where falling objects would impact, while incorporating viewing openings in regions where light transmission is needed. This local differentiation of properties allows simultaneous achievement of protection and illumination.
Solution Approach 2:
The protective cover incorporates viewing openings that function as porous structures, allowing light to pass through while maintaining the protective function. The openings are positioned and sized to permit adequate light transmission for visibility while still providing protection from vertically falling objects.

AI summary
A work vehicle is provided including a frame structurally carrying a cab structure having a brim including a plurality of viewing openings. The cab structure structurally carries a window in close proximity to the brim and is disposed above an operating viewing position. The window and brim are in viewing alignment from the operating viewing position. The window is sufficiently disposed within the cab structure for protection from vertically falling objects.
