Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wheeled engineering vehicles, such as backhoe loaders, suffer from poor stability when supported by conventional support devices, particularly in uneven terrain, leading to reduced operation efficiency.
Innovation Solution
A stabilizer assembly with a first telescopic cylinder and a second stabilizer leg, which can extend or retract and rotate to provide adjustable support spans, combined with a stabilizer foot featuring multiple supporting members for different ground conditions, ensuring stable contact and minimizing deformation of telescopic cylinders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional support device is used to prop up the vehicle and lift tires off the ground, then the vehicle can be supported, but the stability of the vehicle deteriorates
Solution Approach 1:
The support device is divided into two separate stabilizer legs instead of a single support structure. Each leg independently contacts the ground, creating multiple support points that enhance vehicle stability while maintaining support functionality
Solution Approach 2:
The second stabilizer leg is nested within the first stabilizer leg, with the second leg telescoping in and out of the first leg. This nested configuration allows the support device to adjust its length and positioning while maintaining a compact structure, improving both stability and adaptability to different ground conditions
2Adaptability or versatility
If the stabilizer leg length is fixed, then the structure is simple, but the adaptability to different ground conditions deteriorates
Solution Approach 1:
The stabilizer legs are designed with telescopic capability, allowing their length to dynamically adjust based on ground conditions. The second stabilizer leg can extend or retract relative to the first leg, enabling the device to adapt to varying terrain heights and angles while maintaining structural integrity
Solution Approach 2:
The stabilizer feet are equipped with multiple supporting members (toothed members, hooked members, resilient members) that are pre-configured for different ground conditions. Before deployment, the appropriate supporting member is selected and positioned to contact the ground, ensuring optimal adaptation to the specific terrain ahead of time
3Duration of action of stationary object
If the telescopic cylinder is exposed without protection, then the structure is simple, but the service life of the cylinder deteriorates due to deformation
Solution Approach 1:
The first stabilizer leg serves as a protective sleeve that surrounds and shields the second telescopic cylinder from external forces and deformations. This protective configuration prevents direct exposure of the cylinder to ground irregularities and lateral stresses, cushioning it against damage before such damage can occur
Solution Approach 2:
The second telescopic cylinder is nested within the hollow structure of the first stabilizer leg. This nested arrangement provides physical protection for the cylinder while allowing it to extend and retract, extending its service life by preventing deformation from external contact
