Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Trailer management often leads to damage of fixed wires connecting trailers to motor vehicles during separation, resulting in costly repairs.
Innovation Solution
A detachable plug with a main body, first and second sections, a locking clip, and connectors to securely connect and disconnect power transmission between a motor vehicle and a trailer, preventing damage during separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed wires are used to connect trailer to motor vehicle, then power transmission is reliable, but wire damage occurs during separation
Solution Approach 1:
The plug is divided into two separate sections: a first section connected to the motor vehicle and a second section connected to the trailer. These sections can be detached from each other, allowing the trailer to be separated from the motor vehicle without damaging fixed wires. The segmentation enables independent movement of each section while maintaining electrical connection when needed.
Solution Approach 2:
The detachable plug acts as an intermediary device between the motor vehicle and trailer. It provides a controlled interface for power transmission that can be securely connected when needed and safely separated when the trailer needs to be detached, preventing direct wire damage during separation events.
2Object-affected harmful factors
If detachable sections are used to prevent wire damage, then separation safety is improved, but connection stability may be compromised
Solution Approach 1:
The locking clip is springingly disposed and automatically locks the first and second sections together when connected. This preliminary locking action ensures stable connection before any power transmission or trailer operation begins, preventing accidental disconnection while maintaining the ability to deliberately separate when needed.
Solution Approach 2:
The plug design incorporates dynamic elements including a spring-loaded locking clip that can transition between locked and unlocked states, and a barrier that moves between open and closed positions. These dynamic features allow the connection to be stable during operation but easily separable when required, balancing connection stability with separation safety.
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
Prevents wire damage during trailer separation by ensuring secure disconnection, reducing repair costs and time.
Implementation Method 1
a locking clip springingly disposed on at least a portion of at least one of the first section and the second section to lock the first section to the second section
Implementation Method 2
a barrier pivotally disposed on at least a portion of the female end to move from closed over the female end in a first position to at least partially opened away from the female end in a second position
