Support Leg Assembly Weight Sensing for Safe Vehicle Leveling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lifting support arrangements for motorized vehicles lack effective safety measures to ensure stable and safe operation, particularly in detecting and preventing unsafe loading conditions and vehicle instability, which can lead to accidents.
Innovation Solution
A safety device integrated into the lifting support arrangement that includes sensors to detect vehicle weight characteristics, center of gravity, and environmental conditions, providing real-time feedback and initiating safety measures such as preventing vehicle movement if unsafe conditions are detected, and ensuring all leveling jacks are properly engaged with the ground.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a lifting support arrangement operates without integrated weight detection technology, then the device complexity remains low, but safety and reliability are compromised due to undetected weight and loading issues
Solution Approach 1:
The control device is enhanced to perform multiple functions: it not only controls the lifting support arrangement but also detects weight characteristics (total weight, axle loads, center of gravity position) and provides operator information. This multi-functionality integrates safety features into existing infrastructure rather than adding separate dedicated systems.
Solution Approach 2:
The lifting support arrangement uses its own control device and existing sensors to detect weight characteristics and provide safety functions. The system self-monitors its operational state without requiring external detection equipment, thereby improving safety while minimizing additional complexity.
2Reliability
If weight detection technology is integrated into the lifting support arrangement, then safety and reliability improve, but the device complexity increases due to additional sensors and control functions
Solution Approach 1:
The control device is enhanced to perform multiple functions: it not only controls the lifting support arrangement but also detects weight characteristics (total weight, axle loads, center of gravity position) and provides operator information. This multi-functionality integrates safety features into existing infrastructure rather than adding separate dedicated systems.
Solution Approach 2:
The lifting support arrangement uses its own control device and existing sensors to detect weight characteristics and provide safety functions. The system self-monitors its operational state without requiring external detection equipment, thereby improving safety while minimizing additional complexity.
3Reliability
If the lifting support arrangement lacks environment sensing technology, then the device complexity remains low, but the ability to prevent accidents and ensure safe operation is reduced
Solution Approach 1:
