Modular Windscreen Guard Assembly for Easier Cleaning Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional windscreen guards for working machines are bulky, difficult to mount, and require complex assembly, compromising visibility and safety due to adherence of dirt and debris, and pose risks during access for cleaning or maintenance.
Innovation Solution
A modular windscreen guard assembly with a primary and secondary grill segment, where the secondary segment is pivotably mounted, allowing easy access for cleaning and featuring a handle for easy operation, weight distribution for reduced torque, and a hinge assembly for smooth movement, eliminating the need for additional tensioning components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a conventional windscreen guard is used, then protection against impacts is provided, but the structure becomes bulky and difficult to mount
Solution Approach 1:
The windscreen guard is divided into multiple segments (first windscreen guard segment and second windscreen guard segment) that can be separately mounted and assembled. Each segment can be independently positioned and secured to the operator cabin, simplifying the overall assembly process while maintaining protective coverage across the entire windscreen area.
2Strength
If the windscreen guard is fixed, then protection is maintained, but access for cleaning or maintenance becomes difficult and dangerous
Solution Approach 1:
The second windscreen guard segment is configured to be movable relative to the first segment, transitioning between a closed position that provides protection and an open position that enables access to the windscreen for cleaning or maintenance. This dynamic configuration allows the guard to adapt between protective and accessible states.
3Volume of moving object
If the secondary grill segment is mounted close to the pivot edge, then structural compactness is achieved, but torque required for operation increases
Solution Approach 1:
The handle is positioned at the lower edge of the second windscreen guard segment, utilizing the vertical dimension rather than horizontal positioning near the pivot edge. This spatial reconfiguration provides adequate torque lever arm for operation while maintaining a compact overall structure.

AI summary
A working machine that includes a chassis and an operator cabin mounted to the chassis. The operator cabin includes a primary windscreen and a secondary windscreen adjacent to the primary windscreen. Further, the working machine includes a primary grill segment to cover the primary windscreen and a secondary grill segment to cover the secondary windscreen. The primary grill segment is fixedly mounted to the operator cabin and the secondary grill segment is pivotably mounted to the operator cabin to uncover the secondary windscreen in an open position and cover the secondary windscreen in a closed position.
