Solution Overview

Problem

The existing electrical connections between vehicles and trailers are prone to stress and damage due to changes in the angle between the vehicle and trailer during maneuvers like reversing, leading to wear and disconnection of wiring and connections.

Innovation Solution

A rotatable electrical connection system that allows the electrical connector to swivel about a vertical axis, reducing strain on the wiring and connections by accommodating changes in the angle between the vehicle and trailer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a fixed position electrical connection is used between vehicle and trailer, then the connection structure is simple, but the wiring and connection become worn, damaged, or disconnected due to stress from angle changes during maneuvers

Engineering Contradiction:
Improveconnection reliabilityVSAvoidconnection structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by making the electrical connection structure rotatable rather than fixed. The socket assembly can rotate about a vertical axis, allowing it to dynamically adapt to angle changes between the vehicle and trailer during maneuvers like jackknifing. This dynamic capability reduces stress on the wiring and connection components, preventing wear and disconnection while maintaining structural simplicity.

Inventive Principle:
Principle #15Dynamics

2Ease of manufacture

If the electrical connection is made fixed relative to the vehicle, then the installation is simple, but the wires and connection suffer stress and damage when the trailer angle changes

Engineering Contradiction:
Improveinstallation simplicityVSAvoidwiring durability
Core Design Contradiction:
Ease of manufactureVSStrength

Solution Approach 1:

The socket assembly is designed with rotational capability about a vertical axis, allowing it to move dynamically as the trailer angle changes during maneuvers. This dynamic design prevents excessive stress and damage to the wiring and connection components while maintaining ease of installation through a straightforward bracket mounting system.

Inventive Principle:
Principle #15Dynamics

3Reliability

If a rotatable electrical connection is implemented, then stress on wiring and connections is reduced, but the device complexity increases

Engineering Contradiction:
Improvewiring reliabilityVSAvoidconnection apparatus complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The electrical connection apparatus incorporates a rotatable socket assembly that can rotate about a vertical axis, enabling it to adapt to angle changes between vehicle and trailer. This dynamic capability reduces stress on wiring and connection components, preventing wear and disconnection while maintaining structural simplicity through a straightforward bracket mounting system.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The socket assembly serves multiple functions: it provides electrical connection while simultaneously accommodating angular changes through rotation. This multi-functionality reduces the need for additional protective components or complex stress-absorption mechanisms, thereby maintaining device simplicity while improving wiring reliability.

Inventive Principle:
Principle #6Universality (Multi-functionality)
