Trailer Hitch Security Detection System Using Neural Network Classifiers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Trailers often detach from vehicles during motion due to improper attachment, posing safety risks to nearby vehicles, primarily because the chains are not properly crossed, and existing mechanisms lack effective detection systems for secure attachment.
Innovation Solution
A system comprising a sensor, electronic control unit, and output device that detects the security of the hitch connection between a trailer and a vehicle, generating driver notifications and controlling vehicle motion if the attachment is insecure, utilizing neural network classifiers to recognize secure and insecure conditions through video and ultrasonic feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional manual attachment methods are used, then the attachment process is simple, but the reliability of the connection is insufficient due to human error in proper attachment
Solution Approach 1:
The system continuously monitors the hitch connection status using sensors and provides real-time feedback to the control unit. The control unit processes sensor data to determine whether the trailer is properly attached and provides visual and audible feedback to the driver through displays and alarms, enabling corrective action before detachment occurs.
Solution Approach 2:
The patent replaces manual mechanical attachment verification with an automated sensor-based detection system. Optical sensors, ultrasonic sensors, or RFID readers automatically detect the presence and proper configuration of chains, latches, and pins, substituting human judgment and manual inspection with electronic detection and control systems.
2Reliability
If detection systems are added to monitor hitch security, then the reliability of connection monitoring improves, but the device complexity increases
Solution Approach 1:
The control unit serves multiple functions: it receives data from various sensor types, processes the information to determine attachment status, controls vehicle motion, and provides driver notifications. This multi-functionality reduces the need for separate dedicated systems for each function, thereby limiting the increase in overall system complexity.
Solution Approach 2:
The control unit acts as an intermediary between the sensors and the vehicle's motion control systems. It processes sensor data and translates it into appropriate control actions, such as preventing vehicle motion when attachment is improper. This intermediary role simplifies the integration of detection systems with existing vehicle control mechanisms.
3Object-affected harmful factors
If the system controls vehicle motion to prevent detachment, then safety improves, but the ease of operation decreases due to motion restrictions
Solution Approach 1:
The system prevents harmful detachment events by taking preliminary action before they occur. When sensors detect improper attachment, the control unit proactively controls vehicle motion to prevent detachment, rather than reacting after detachment occurs. This preliminary protective action eliminates safety risks before they can manifest.
Solution Approach 2:
The system automatically monitors attachment status and controls vehicle motion without requiring continuous driver intervention. The driver simply needs to ensure proper attachment initially, and the system handles ongoing monitoring and safety control autonomously, reducing the operational burden on the driver while maintaining safety.
