Backhoe Chassis Vertical Lift for Stabilizer Disengagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of work vehicles, such as tractors and backhoes, face fatigue and inefficiencies due to the manual process of excavating soil, which can lead to inaccuracies in excavation dimensions and increased time spent correcting errors, resulting in reduced productivity.
Innovation Solution
A control system for work vehicles that includes a processor and memory device, allowing for automatic relocation operations by disengaging stabilizers and moving the vehicle vertically to facilitate efficient movement and excavation, using a suspension system to raise and lower the chassis and engage/disengage stabilizers as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual relocation and excavation operations are performed, then operator control and flexibility are maintained, but operator fatigue increases and productivity decreases
Solution Approach 1:
The system enables the work vehicle to perform relocation operations autonomously by detecting stabilizer engagement status and automatically executing the sequence of raising chassis, moving to target location, and lowering chassis without operator intervention, allowing the system to service itself
Solution Approach 2:
The patent replaces manual mechanical operations with an automated control system that uses sensors to detect stabilizer engagement and controllers to orchestrate the relocation sequence, substituting human physical operations with electronic control mechanisms
2Manufacturing precision
If manual excavation operations are performed, then operator flexibility is maintained, but excavation dimension accuracy decreases
Solution Approach 1:
The system incorporates sensors that detect stabilizer engagement status and provide feedback to the controller, which then automatically adjusts the relocation operations to achieve precise excavation dimensions without operator error
Solution Approach 2:
The patent replaces manual positioning and measurement operations with automated electronic control systems that calculate and execute precise movement to target locations, ensuring accurate excavation dimensions
3Speed
If stabilizers remain engaged during movement, then vehicle stability is maintained, but vehicle relocation is prevented
Solution Approach 1:
The system dynamically adjusts stabilizer engagement status based on operational phase - maintaining engagement during excavation for stability, and disengaging during relocation for mobility, with automatic transition between states controlled by sensor feedback
Solution Approach 2:
The system automatically detects stabilizer engagement status and initiates the appropriate sequence of operations without operator input, self-managing the transition between stable excavation mode and mobile relocation mode

Data Source
AI summary
A control system for a work vehicle, includes a controller. The controller includes a processor a memory device communicatively coupled to the processor, such that the memory device stores instructions that cause the processor to receive a first control signal indicative of performing relocation operations. Furthermore, the instructions cause the processor to instruct an actuator assembly to drive a chassis of the work vehicle in an upward direction relative to wheels of the work vehicle in response to receiving the first control signal, such that a front stabilizer and a rear stabilizer are disengaged from a ground.
