Agricultural Vehicle Frame Segmentation for Load Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural work vehicles face issues with engine frame deformation and excessive weight due to the mounting of loader and backhoe working machines, leading to potential damage and reduced fuel economy.
Innovation Solution
A frame device for agricultural work vehicles that includes an engine frame, a protection frame connected to the driver's seat and engine frame, and a rear frame connected to the rear working machine, with detachable connection members to share loads and reduce weight, thereby supporting the working machines without increasing the engine frame's weight unnecessarily.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If both the loader working machine and the backhoe working machine are mounted on the engine frame, then the supporting force for working machines is improved, but the engine frame may be deformed or damaged due to excessive load
Solution Approach 1:
The patent divides the supporting structure into multiple independent frames: a front frame for mounting the loader working machine, a rear frame for mounting the backhoe working machine, and the engine frame for mounting the engine. This segmentation distributes the loads from working machines across different structural components, preventing excessive concentration of force on the engine frame and thereby reducing deformation and damage risks while maintaining adequate supporting capability.
2Strength
If the engine frame is enhanced in strength to support both working machines, then the supporting force is improved, but the weight of the engine frame increases causing excessive total vehicle weight
Solution Approach 1:
The patent segments the load-bearing function across multiple frames (front frame, rear frame, and engine frame), allowing each frame to be optimized for its specific load requirements rather than requiring the engine frame to support all working machines. This enables the engine frame to be lighter while the overall vehicle maintains sufficient supporting force through the distributed frame structure.
Solution Approach 2:
The patent applies local quality by providing enhanced structural support specifically at locations where working machines are mounted (front frame for loader, rear frame for backhoe) rather than uniformly strengthening the entire engine frame. This localized reinforcement approach achieves the necessary supporting force while minimizing unnecessary weight increase.
3Strength
If the engine frame is made heavier to provide sufficient supporting force, then the supporting force is improved, but fuel economy is reduced due to excessive vehicle weight
Solution Approach 1:
The patent segments the supporting function across multiple frames, enabling the engine frame to remain lighter while the vehicle maintains adequate supporting force through the distributed frame structure. This weight reduction directly improves fuel economy by decreasing the energy required for vehicle operation.
