Solution Overview

Problem

Existing motor vehicle door handle arrangements often collide with the door body when pivoting, limiting design flexibility and requiring precise movement curve consideration during recess design.

Innovation Solution

A handle arrangement featuring a circular arc-shaped guide track in the carrier, allowing the support arm to pivot about a virtual center point, preventing collision by maintaining a consistent distance from the door edge, and enabling flexible design with adjustable pivot center.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the handle body is pivotably mounted directly on the carrier without a guide track, then the structure is simpler, but the handle body collides with the door body during pivoting

Engineering Contradiction:

Improvestructure simplicityVSAvoidcollision with door body

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a circular arc-shaped guide track as an intermediary element between the support arm and the carrier. This guide track mediates the pivoting motion, guiding the support arm along a predetermined circular arc path that prevents collision with the door body while maintaining structural simplicity.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent employs a circular arc-shaped guide track with a specifically designed radius. The curved geometry of the guide track ensures that the handle body follows a circular pivoting path, maintaining a constant distance from the door body edge and preventing collision during the opening motion.

Inventive Principle:

Principle #14Spheroidality (Curvature)

2Ease of manufacture

If the pivot center is fixed within the door body, then the mounting is simpler, but the design flexibility is reduced

Engineering Contradiction:

Improvemounting simplicityVSAvoiddesign flexibility

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent enables adjustment of the pivot center position by modifying parameters of the circular arc-shaped guide track, such as its radius and orientation. This allows the pivot center to be positioned optimally for different door designs and handle configurations, providing design flexibility while maintaining simple mounting through the standardized guide track structure.

AI summary

The present invention relates to the area of the vehicle door handle, specifically to a handle assembly for a motor vehicle door. The handle assembly for a motor vehicle door comprises a carrier arranged on the inside of the door panel, a handle body arranged on the outside of the door, the handle body having a first end section and a second end section, the second end section being pivotably mounted on the carrier from the outside of the vehicle door by means of a recess, the second end section having a support arm with a curvature, characterized in that a circular arc-shaped guide track is arranged in the carrier, the support arm of the second end section being designed to pivotably slide in the carrier about the center point of the circular arc.The present invention makes it possible for the door handle arrangement to not collide with the door body when pivoting, and for the design to be more flexible.
