Vehicle Cargo Restraint Control for Early Fall Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cargo falls off vehicles due to traveling vibrations or wind pressure, posing a risk of accidents and injuries, with existing methods failing to prevent or recognize such incidents effectively.
Innovation Solution
A cargo falling prevention system with movement detectors and a controller that deploy a falling prevention device to restrict cargo motion, determining defective or falling-off states based on cargo movement and weight changes, and adjusting vehicle controls accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a cargo platform is equipped for loading cargo, then cargo can be transported, but cargo falls off due to traveling vibration or wind pressure causing accidents
Solution Approach 1:
The falling prevention device is deployed in advance before cargo falls off, based on detection of cargo movement trends. The controller activates the prevention device when motion detectors identify abnormal cargo movement, preventing the harmful effect before it occurs.
Solution Approach 2:
Motion detectors continuously monitor cargo position and provide feedback to the controller. When cargo movement exceeds thresholds, the system responds by deploying the falling prevention device, creating a closed-loop control system that maintains cargo stability.
2Speed
If the cargo platform moves toward the driver seat during sudden stops, then vehicle stopping is enabled, but the driver seat collides with cargo causing driver injury
Solution Approach 1:
The falling prevention device creates a protective barrier before cargo can move forward and collide with the driver seat during sudden stops. The device is activated based on detected cargo movement trends, preventing the harmful collision before it occurs.
3Device complexity
If no detection system is installed, then the system is simple, but there is no solution for recognizing or preventing cargo falling
Solution Approach 1:
The system replaces complex mechanical restraint mechanisms with a sensor-based detection and actuation system. Motion detectors and weight detectors use electrical fields and signal processing to monitor cargo, substituting mechanical complexity with electronic sensing and control.
