Work Vehicle Weight Attachment for Stability and Space Utilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work vehicles face instability due to increased vehicle body height from downward-projecting weights, and foreign substances like soil and mud can intrude into gaps between weight and frame, while upward projection of weights reduces space for other devices.
Innovation Solution
A weight attachment system where the upper end is positioned either at or above the lower end of the vehicle body frame, minimizing downward projection and preventing gaps, with the weight being overlapped with the front axle case for effective load distribution and utilizing space between front frames for attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the weight projects downward from the lower end portion of the vehicle body frame, then the weight can be attached to extend under the frame, but the vehicle body height increases causing instability and foreign substances can enter the gap
Solution Approach 1:
The weight is repositioned from a downward projection to an upward extension beyond the upper end portion of the front frame. This dimensional change in attachment orientation eliminates the gap problem at the lower end while utilizing vertical space above the frame, thereby maintaining vehicle stability and preventing foreign substance intrusion.
2Volume of moving object
If the weight projects downward from the lower end portion of the vehicle body frame, then the weight can be attached to extend under the frame, but foreign substances such as soil and mud can intrude into the gap
Solution Approach 1:
The weight attachment is shifted from the lower end region to extend beyond the upper end portion of the front frame in the vertical direction. This repositioning eliminates the gap between the weight and frame at the lower end, thereby preventing soil and mud from entering while still providing adequate weight disposing space through vertical extension.
3Length of moving object
If the upper end portion of the weight projects upward beyond the upper end portions of the front frames, then the weight can be attached with sufficient vertical extension, but the weight disposing space needs to be secured upwardly inviting enlargement of the disposing space
Solution Approach 1:
The weight structure serves multiple functions: it extends beyond the upper end portion of the front frame to provide sufficient vertical length for weight disposition, while simultaneously acting as a support structure for mounting devices such as batteries and horns. This multi-functional design maximizes space utilization without requiring additional dedicated spaces.
4Length of moving object
If the upper end portion of the weight projects upward beyond the upper end portions of the front frames, then the weight can be attached with sufficient vertical extension, but the disposing space for other devices inside the engine room is reduced
Solution Approach 1:
The vehicle's device mounting spaces are segmented into two distinct regions: devices requiring protection from foreign substances are mounted inside the engine room, while devices tolerant of external exposure (battery, horn) are mounted on the weight structure extending beyond the front frame. This spatial segmentation allows both the weight to extend upward for sufficient length while preserving engine room space for other devices.

AI summary
Disclosed is a work vehicle having a weight that can be attached to a vehicle body frame. The weight is attached in such a manner that, over an entire length in a front/rear direction of the vehicle body and in a vertical direction of the vehicle body, an upper end portion of the weight is disposed in a same position as or upwardly of a lower end portion of the vehicle body frame, and at the same time in a same position as or downwardly of an upper end portion of the vehicle body frame.
