Trailer Auxiliary Drive Gradient Feedback System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing auxiliary drive systems for trailers lack the ability to provide users with real-time gradient information, making it difficult to maneuver trailers safely and avoid dangerous slopes during uncoupled operation.
Innovation Solution
A method and system that uses a terminal device connected to the auxiliary drive via a communication link to provide users with gradient information through a human-machine interface, including optical, acoustic, and haptic feedback, allowing the system to warn users of impermissible inclines and adjust the drive's operation to avoid them.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If auxiliary drive systems are used to maneuver uncoupled trailers, then the ability to move trailers independently is improved, but the safety of maneuvering on various terrains deteriorates due to lack of gradient information
Solution Approach 1:
The system provides real-time gradient information feedback to the user through display devices and auditory signals, enabling informed decision-making when maneuvering the uncoupled trailer on various terrains
Solution Approach 2:
The system determines gradient information in advance before the trailer encounters dangerous slopes, allowing the user to plan the maneuvering path and avoid impermissible gradients proactively
2Reliability
If gradient information is provided through multiple channels (optical, acoustic, haptic), then the reliability of information delivery is improved, but the device complexity increases
Solution Approach 1:
The terminal device serves multiple functions: it acts as both the control interface for the auxiliary drive and the information display device, integrating gradient information presentation with drive control in a single universal device
