Active Cargo Conveyor Control for Freight Stability in Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles used for logistics face challenges in preventing freight from shaking or moving due to inertia or gravity during rapid maneuvers or inclines, leading to potential damage.
Innovation Solution
A conveyor device with controllable rotating bodies is installed in the loading box, controlled by a controller to adjust rotation direction, torque, and angle to counteract shaking or movement of freights based on driving conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional fixed freight loading is used, then device complexity is low, but freight stability deteriorates during rapid maneuvers or inclines
Solution Approach 1:
The patent applies dynamics by transforming the static conveyor device into a dynamic system where rotating bodies can independently adjust their rotation directions, torques, and angles in real-time based on detected freight movement, enabling active stabilization rather than passive fixed support
Solution Approach 2:
The conveyor device is segmented into multiple independently controllable rotating bodies arranged in a matrix, allowing localized adjustment of individual rotating bodies to counteract specific movement directions of freight without requiring system-wide changes
2Stability of the object's composition
If multiple independently controllable rotating bodies are used, then freight stability improves, but device complexity increases
Solution Approach 1:
Each rotating body in the matrix is designed with universal multi-functionality, capable of performing multiple stabilization functions (counteracting forces in different directions, adapting to various freight weights and positions) through controlled variations in rotation direction, torque, and angle, reducing the need for specialized components for each function
3Stability of the object's composition
If active control of rotating bodies is implemented, then freight stability improves during maneuvers, but use of energy increases
Solution Approach 1:
The system implements feedback control by detecting freight movement on the conveyor device and using this information to adjust the rotation directions, torques, and angles of rotating bodies, enabling energy-efficient operation by applying control only when and where needed rather than continuous full-power operation
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively suppresses freight movement and shaking by predicting and counteracting forces through controlled rotation and torque adjustments, ensuring freight stability during vehicle maneuvers.
Implementation Method 1
the freights loaded in a loading box may be damaged by shaking or impact caused by movement. For example, in situations such as rapid deceleration or rapid acceleration of the mobility device for logistics, a sharp curve, driving on an incline, and parking on an incline, the freights inside the loading box may be shaken or moved due to inertia or gravity.
Implementation Method 2
the freights loaded in a loading box may be damaged by shaking or impact caused by movement. For example, in situations such as rapid deceleration or rapid acceleration of the mobility device for logistics, a sharp curve, driving on an incline, and parking on an incline, the freights inside the loading box may be shaken or moved due to inertia or gravity.
