Magnetic Stabilizer for Tractor Line Springs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing systems for holding and storing disconnected lines of a tractor unit cause paint peeling and noise due to springs hitting the rear cabin while driving, especially on uneven surfaces, as they are not effectively stabilized in the uncoupled configuration.
Innovation Solution
A magnetic stabilizer system that uses a steel spring and axial grooves to maintain the spring in a rest position, preventing lateral displacement and keeping lines near the rear wall, combined with an electro-magnet and proximity sensor for automatic switching, ensuring the spring is secured in both coupled and uncoupled configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If springs are used to hold disconnected lines from the back of the cabin, then the lines can be maintained immobile during movement, but the springs and lines hit the back of the cabin causing paint peeling and noise
Solution Approach 1:
A magnetic stabilizer is introduced as an intermediary component between the spring and the back of the cabin. The stabilizer includes a magnetic element that attracts the spring (made of ferromagnetic material) to keep it positioned away from the cabin surface, preventing direct contact while maintaining stability of the disconnected lines.
2Adaptability or versatility
If the spring is extended to enable line extension in coupled configuration, then the lines can accommodate trailer connection, but the spring may knock against the rear wall in uncoupled configuration
Solution Approach 1:
The system dynamically adapts its configuration based on whether a trailer is coupled or not. In uncoupled configuration, the magnetic stabilizer actively positions the spring away from the rear wall. In coupled configuration, the spring extends naturally to accommodate the trailer connection, with the magnetic stabilizer no longer restricting its movement.
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
The magnetic stabilizer effectively prevents the spring from knocking against the rear wall, maintaining the lines in a stable position during driving, reducing noise and paint damage, and allowing independent operation of the tractor unit without damaging the cabin.
Implementation Method 1
a magnetic stabilizer configured for attracting and maintaining in a rest position a spring made of ferromagnetic material
Implementation Method 2
an electro-magnet and proximity sensor for automatic switching

AI summary
System for holding and storing disconnected lines of a tractor unit, each line comprising, at one end, a coupling configured to be coupled to a complementary coupling of a trailer so as to pneumatically or electrically connect the trailer to the tractor unit, the system for holding and storing comprising a first retaining mechanism comprising a bracket designed to be fixed on a rear wall of the tractor unit and at least one spring having a first extremity attached to the bracket and a second extremity on which at least one of the lines can be hung; and a second retaining mechanism for receiving and holding the couplings arranged at the end of the lines; the system for holding and storing further including a magnetic stabilizer configured for attracting and maintaining the spring in a rest position when the tractor unit is moving without trailer.
