Curved Operator Shield Structure for Vegetation and Roll-Over Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work vehicle designs lack effective protection for the operator from vegetation and do not provide adequate roll-over protection while maintaining visibility and operational efficiency.
Innovation Solution
A curved structure comprising a first and second curved support, a windshield, and base portions attached to the vehicle's chassis, forming an arc angle between 60° to 120°, which serves as a barrier against vegetation and functions as a roll-over protection system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a curved structure is positioned behind the operator seat, then roll-over protection is provided, but protection from vegetation entering the operator station is insufficient
Solution Approach 1:
The curved structure is repositioned from behind the operator seat to the front of the operator station, changing its spatial dimension and location. This allows the structure to simultaneously block vegetation from entering the operator station while maintaining roll-over protection capabilities through its curved geometry and structural design
2Object-affected harmful factors
If a curved structure extends upward and rearward beyond the seat, then vegetation protection is improved, but visibility may be compromised
Solution Approach 1:
The curved structure is designed with specific geometric properties - extending upward and rearward beyond the seat - that create localized protection zones. The curved geometry is configured to deflect vegetation away from the operator station while maintaining clear visibility paths for the operator through strategic positioning and shape optimization
3Object-affected harmful factors
If the curved structure is positioned forward of the steering wheel, then vegetation protection is enhanced, but device complexity increases
Solution Approach 1:
The curved structure serves multiple functions simultaneously: it acts as a vegetation barrier when positioned forward of the steering wheel, provides roll-over protection through its curved geometry, and can be mounted using standardized mounting structures. This multi-functionality reduces the need for separate protective devices and simplifies the overall system despite the forward positioning

AI summary
A curved structure for a work vehicle includes a first curved support extending a length, a second curved support extending a length, the second curved support spaced apart a width from the first curved support, and a curved windshield positioned between and connected to the first and second curved supports.
