Solution Overview

Problem

Existing trailer couplings lack an aesthetically pleasing design while maintaining functional integrity and protection from environmental elements.

Innovation Solution

A non-load-bearing cladding or cover is applied to the support structure, made of flexible or rigid materials like molded plastic or metal, which covers free spaces to enhance appearance and provide protection without significantly affecting the mechanical properties, and can include functional units like sensors and electrical connectors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If a cladding is added to the support structure to improve appearance and protection, then aesthetic appearance and environmental protection are improved, but device complexity increases

Engineering Contradiction:
Improveaesthetic appearanceVSAvoidstructure complexity
Core Design Contradiction:
ShapeVSDevice complexity

Solution Approach 1:

The patent applies a cladding as a separate, replaceable component that can be easily manufactured and installed. This disposable-like approach allows the support structure to gain aesthetic coverage and protection without permanently complicating the core structural design, as the cladding can be independently produced and attached.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The cladding acts as a flexible or rigid shell that envelops the support structure, providing aesthetic coverage and environmental protection. This shell approach allows the underlying structural geometry to remain simple while achieving the desired appearance and protection through an outer layer.

Inventive Principle:
Principle #30Flexible shells and thin films

2Shape

If a non-load-bearing cladding is used to improve appearance, then aesthetic appearance is improved, but protection against environmental factors is reduced

Engineering Contradiction:
Improveaesthetic appearanceVSAvoidenvironmental protection
Core Design Contradiction:
ShapeVSObject-affected harmful factors

Solution Approach 1:

The cladding serves as a protective shell that, while non-load-bearing, provides a barrier against environmental factors such as water jets and stone chips. This shell approach allows the component to gain both aesthetic appearance and environmental protection simultaneously, despite not contributing to structural strength.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The cladding is designed as a separate, replaceable component that can be easily manufactured from durable materials. This approach allows for the use of materials specifically selected for environmental resistance without compromising the core structural integrity, providing protection against harmful factors while maintaining aesthetic appearance.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Shape

If the cladding covers all free spaces of the support structure, then aesthetic appearance is improved, but manufacturing complexity increases

Engineering Contradiction:
Improveaesthetic appearanceVSAvoidmanufacturing complexity
Core Design Contradiction:
ShapeVSEase of manufacture

Solution Approach 1:

The cladding is designed as a separate, modular component that can be independently manufactured and then attached to the support structure. This segmentation allows the aesthetic covering to be produced using standard manufacturing processes without complicating the fabrication of the load-bearing support structure itself.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cladding is designed as a shell component that can be produced using conventional molding or forming processes. This shell approach allows for complete coverage of free spaces to achieve aesthetic appearance while maintaining relatively simple manufacturing through standardized shell production methods.

Inventive Principle:
Principle #30Flexible shells and thin films

AI summary

The invention relates to a trailer coupling comprising a vehicle-mounted mounting unit, a bearing unit held on the mounting unit with which a first end region of a support structure of a ball neck is connected, and a coupling element arranged on a second end region of the support structure of the ball neck, in particular designed as a coupling ball, wherein the support structure in a working position comprises a top surface facing away from a roadway, a bottom surface facing the roadway and longitudinal sides located between these on both sides, wherein the support structure is provided with a covering which covers at least one of the sides with a cover at least in a partial area located between the first end region and the second end region.
