Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing single movement stabilization systems are inadequate for medium or high-capacity vehicles, as they have limited stabilization arm lengths, leading to increased production costs and complexity when trying to prevent overturning, especially in vehicles with movable arms.
Innovation Solution
A single movement stabilization system with a greater support arm, featuring oblique positioning of the actuator means relative to the vehicle's symmetry axis, utilizing hydraulic cylinders and tie rod elements with sliding blocks to minimize friction, and a mechanical lock to ensure stable operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single movement stabilization system is used for medium or high-capacity vehicles, then the system complexity and production costs are reduced, but the stabilization arm length is limited and insufficient for preventing overturning
Solution Approach 1:
The stabilization arm incorporates a telescopic mechanism with nested segments that can extend and retract. The inner telescopic segment is housed within the outer arm structure, allowing the arm to achieve greater extended length while maintaining a compact retracted profile. This nesting principle enables the single movement system to provide sufficient stabilization arm length for medium and high-capacity vehicles without requiring a complex double movement system.
Solution Approach 2:
The stabilization arm transitions from a static fixed-length structure to a dynamic telescopic structure that can adjust its length. The telescopic mechanism allows the arm to extend to the required length for stabilization and then retract to a shorter position during transport or when not in use. This dynamic capability enables the single movement system to achieve the performance of a longer arm while maintaining operational simplicity.
2Reliability
If the distance between support arms is increased to prevent overturning, then the stabilization capacity is improved, but the vehicle size and footprint are increased
Solution Approach 1:
The telescopic stabilization arms use nested segments that allow the arms to extend to a greater distance from the vehicle center when needed for stabilization, increasing the support base area and preventing overturning. When retracted, the nested segments collapse into a compact configuration that minimizes the vehicle footprint during transport and storage. This enables the vehicle to achieve high stabilization capacity without permanently occupying excessive space.
3Length of stationary object
If a double movement stabilization system is used to achieve greater stabilization arm lengths, then the stabilization capacity is improved, but the system complexity and production costs increase
Solution Approach 1:
The system uses a single movement mechanism that actuates both the stabilization arm extension and the telescopic segment deployment simultaneously through a unified hydraulic or mechanical actuation system. This dynamic coordination eliminates the need for separate movement stages and complex multi-stage control systems required in double movement designs, achieving long arm length with simplified system architecture and reduced production costs.
