Solution Overview

Problem

Existing support arrangements for vehicles and trailers are expensive and require significant design changes or weakening of the frame to provide electrical energy, particularly for commercial vehicle trailers, which need electrical power for lighting and traction drives.

Innovation Solution

A support arrangement that includes an axle support element and a recuperation device mounted directly or indirectly on the axle support element, which converts kinetic energy from the wheel into electrical energy, allowing for a cost-effective and simple electrical energy supply without the need for internal combustion engines or extensive design modifications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If an internal combustion engine or generator is arranged in the axle hub or on the frame to provide electrical energy, then electrical power supply is improved, but device complexity and cost increase significantly

Engineering Contradiction:
Improveelectrical energy supplyVSAvoidcomplexity of power supply system
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The invention extracts the generator from the traditional power supply systems (frame-mounted or hub-integrated) and relocates it to the axle support element. This extraction simplifies the overall system by eliminating the need for complex routing and mounting structures while maintaining the electrical power supply function.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The axle support element itself serves dual functions: mechanical support for the axle and mounting structure for the generator. This self-service approach eliminates the need for separate frame modifications or hub integrations, reducing system complexity while providing electrical energy.

Inventive Principle:
Principle #25Self-service

2Use of energy by moving object

If a generator is arranged in the axle hub or on the frame, then electrical energy is provided, but the frame is weakened and significant design changes are required

Engineering Contradiction:
Improveelectrical energy supplyVSAvoidframe strength
Core Design Contradiction:
Use of energy by moving objectVSStrength

Solution Approach 1:

The generator mounting function is extracted from the frame structure and transferred to the axle support element. This extraction preserves the frame's structural integrity by eliminating the need for frame modifications, while the axle support element provides the necessary mounting surface without compromising frame strength.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The mounting function is segmented from the frame structure and assigned to the axle support element. This segmentation allows the frame to maintain its original strength characteristics while the axle support element serves as a dedicated mounting platform for the generator.

Inventive Principle:
Principle #1Segmentation

3Use of energy by moving object

If an internal combustion engine or generator is arranged to provide electrical energy, then power supply is improved, but expensive components and significant design changes are required

Engineering Contradiction:
Improveelectrical energy supplyVSAvoidcost-effectiveness of implementation
Core Design Contradiction:
Use of energy by moving objectVSEase of manufacture

Solution Approach 1:

The invention merges the generator mounting function with the axle support element, combining two previously separate functions into a single integrated component. This merging eliminates the need for separate mounting structures and reduces overall system cost while maintaining electrical power supply capability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The axle support element is designed with multi-functionality, serving both as a mechanical support for the axle and as a mounting structure for the generator. This universality reduces the need for additional components and simplifies manufacturing, improving cost-effectiveness.

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