Cab Frame Hose Installation Member for Work Vehicle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work vehicle designs face challenges in securely and efficiently routing hydraulic hoses when the cabin is rotated, leading to potential hose deviation and installation complexities due to the absence of a dedicated hose management system.
Innovation Solution
A hose installation member with an engaging portion, extending portion, and hose holding members is integrated into the cab frame, featuring a beam structure that secures hydraulic hoses and prevents them from deviating during cabin rotation, utilizing a fastener and support system to maintain hose alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cabin is freely opened and closed without a dedicated hose management system, then the cab frame can be easily accessed and maintained, but the hydraulic hoses may deviate or become misaligned during cabin rotation
Solution Approach 1:
The patent introduces a hose installation member as an intermediary component between the hydraulic hose and the cab frame. This member includes a hose holding member that secures the hose and a pivot member that allows it to move with the cabin rotation, preventing hose deviation while maintaining cabin accessibility.
Solution Approach 2:
The hose installation member is designed with a pivot member that can rotate along with the cabin frame. This dynamic design allows the hose to accommodate the cabin's movement without becoming misaligned or strained, maintaining reliable connection throughout the range of motion.
2Ease of manufacture
If hydraulic hoses are routed without a dedicated support structure, then the installation process is simpler, but the hoses are more prone to deviation and require frequent maintenance
Solution Approach 1:
The hose installation member is designed to be self-aligning through its pivot mechanism. The hose holding member automatically adjusts its position as the cabin rotates, eliminating the need for frequent manual alignment or maintenance adjustments.
Solution Approach 2:
The hose installation member is pre-installed on the cab frame before the hydraulic hose is connected. This preliminary positioning ensures that the hose is already in the correct alignment and secured properly, preventing future alignment issues and reducing maintenance needs.
3Reliability
If a relay member is used to connect the pilot hose, then the hose connection is more secure, but the overall system complexity increases
Solution Approach 1:
The patent combines multiple functions into a single hose installation member: the hose holding member secures the hydraulic hose, the pivot member allows rotation, and the engaging portion connects to the cab frame. This integration achieves secure connection without requiring multiple separate components, reducing overall system complexity.

AI summary
A work vehicle includes a vehicle body frame, a cab frame attached to the vehicle body frame so as to be rotatable around a pivot axis, a support provided on the cab frame, a fastener provided on the cab frame and between the support and the pivot axis in a radial direction from the pivot axis, a hydraulic hose, and a hose installation member. The hose installation member includes an engaging portion connected to the fastener, an extending portion configured to be supported on the support, a beam portion connecting the engaging portion and the extending portion, and a first hose holding member provided on the beam portion and having a first opening through which the hydraulic hose passes.
