Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wheeled engineering vehicles, such as backhoe loaders, face stability issues when using support devices that prop up the vehicle, leading to poor operation efficiency, especially on uneven ground surfaces.
Innovation Solution
A stabilizer assembly with a first telescopic cylinder and a second telescopic cylinder, which allows the stabilizer legs to extend or retract, providing adjustable support spans and improving stability by maintaining contact with the ground through a stabilizer foot with adaptable supporting members for various ground conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a support device is used to prop up the vehicle and lift tires off the ground, then operation safety is improved, but vehicle stability deteriorates due to poor contact with the ground
Solution Approach 1:
The stabilizer leg employs a telescopic structure with multiple sections that can extend and retract dynamically. The second stabilizer leg can extend outward from the first stabilizer leg to increase the support span and improve stability, then retract when not needed. This dynamic adjustment allows the support device to adapt to different ground conditions while maintaining vehicle stability.
Solution Approach 2:
The stabilizer leg is divided into multiple segments: a first stabilizer leg connected to the vehicle, and a second stabilizer leg that can extend from the first. This segmentation allows independent adjustment of each section to optimize both the support function and the stability span, resolving the contradiction between support capability and stability.
2Device complexity
If the stabilizer leg structure is simplified, then device complexity is reduced, but adaptability to different ground conditions deteriorates
Solution Approach 1:
The second stabilizer leg is nested within or alongside the first stabilizer leg, allowing it to extend outward when needed and retract into a compact configuration when not in use. This nesting approach provides adaptability to different ground conditions without significantly increasing the overall structural complexity or storage space requirements.
Solution Approach 2:
The telescopic mechanism allows the stabilizer leg to dynamically adjust its length and configuration based on ground conditions. The second stabilizer leg can be extended to reach uneven or distant ground surfaces, then retracted for transport or storage, providing versatility without permanent structural complexity.
3Stability of the object's composition
If the support span is increased to improve stability, then vehicle stability is improved, but device complexity increases due to additional components
Solution Approach 1:
The stabilizer assembly is segmented into a first stabilizer leg for primary support and a second stabilizer leg for extended support span. This segmentation allows the stability function to be enhanced by adding only the necessary additional components rather than redesigning the entire structure, managing complexity through functional division.
Solution Approach 2:
The telescopic mechanism enables the stabilizer leg to extend to a larger support span only when stability is needed, rather than permanently maintaining a complex extended structure. The dynamic extension and retraction capability provides increased stability on demand while keeping the device simpler during transport and storage.
