Work Vehicle ROPS Assembly via Separate Rod Bracket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing work vehicles, such as tractors, face difficulties in handling the rollover protection structure (ROPS) during assembly due to its integration with the rod bracket, making the process cumbersome and inefficient.
Innovation Solution
The ROPS is designed to be handled independently of the rod bracket, with the rod bracket being provided separately from the left and right struts, and supported by a rigid supporting member, allowing for improved assembly readiness and reduced component complexity.

Engineering Contradiction Analysis
1Strength
If the rod bracket is provided integrally with the ROPS, then the structural strength and rigidity are improved, but the handling readiness and ease of assembly deteriorate
Solution Approach 1:
The rod bracket is separated from the ROPS structure into an independent component. The ROPS consists of left and right struts that can be assembled separately from the rod bracket, which is then mounted independently to support the hook rod. This segmentation allows each component to be manufactured and handled separately, improving assembly ease while maintaining structural integrity through proper connection design.
2Stability of the object's composition
If the ROPS is handled together with the rod bracket, then the structural integrity is maintained, but the assembly process complexity increases
Solution Approach 1:
The assembly process is segmented into distinct stages: first assembling the ROPS struts to the vehicle frame, then separately mounting the rod bracket. This reduces assembly complexity by allowing workers to handle smaller, more manageable components independently rather than dealing with a large integrated assembly.
Solution Approach 2:
The rod bracket is designed as a universal component that can be independently mounted and serves multiple functions: supporting the hook rod, providing a mounting point for the locking mechanism, and maintaining structural stability. This multi-functionality reduces the need for additional specialized components.
3Ease of operation
If the rod bracket is provided separately from the struts, then the ease of assembly is improved, but the number of components increases
Solution Approach 1:
The rod bracket combines multiple functions into a single component: it supports the hook rod, provides mounting points for the locking mechanism, and maintains structural stability. By merging these functions into one component rather than using separate elements for each function, the total number of components is minimized while still providing separate handling capability.

AI summary
Provided is a work vehicle having a rollover protection structure (ROPS) around a driver's seat which is switchable between a front seating posture and a rear seating posture. A locking mechanism locks the driver's seat to the rear seating posture. The locking mechanism includes a hook provided on the driver's seat side, a hook rod disposed between a left strut and a right strut and engageable with the hook when the driver's seat is switched to the rear seating posture, and a rod bracket for supporting the hook rod. The rod bracket is provided separately from the left strut and the right strut.
