Die-Cast Crossbeam A-Pillar Mounting Footwell Space

Solution Overview

Problem

Current motor vehicle designs often require a central tunnel-like member or console to support the crossbeam, dividing the footwell into separate driver and passenger regions, which limits space and stability.

Innovation Solution

A die-cast crossbeam is mounted exclusively on the A-pillars, eliminating the need for additional vehicle base supports and incorporating a U-shaped support and plate for increased rigidity and guiding ventilation and cables, forming a continuous open footwell.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a central tunnel-like member or console is used to support the crossbeam, then the crossbeam stability is improved, but the footwell space is reduced and the passenger compartment is divided into separate regions

Engineering Contradiction:

Improvecrossbeam stabilityVSAvoidfootwell space

Core Design Contradiction:

Stability of the object's compositionVSArea of stationary object

Solution Approach 1:

The invention extracts and eliminates the central tunnel-like member or console from the vehicle structure. By removing this intermediate support element, the footwell space is fully liberated and no longer divided, while the crossbeam maintains stability through alternative support configurations on the vehicle floor at the A-pillar locations.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The invention merges the support function directly into the A-pillar regions by positioning support elements at the front corners of the vehicle floor. This consolidation eliminates the need for a separate central support structure, integrating the stabilization function into the existing A-pillar support architecture.

Inventive Principle:

Principle #5Merging (Combining)

2Stability of the object's composition

If a central tunnel-like member or console is used to support the crossbeam, then the crossbeam stability is improved, but the device complexity increases

Engineering Contradiction:

Improvecrossbeam stabilityVSAvoidsupport structure complexity

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The invention extracts and eliminates the central tunnel-like member or console from the vehicle structure. By removing this intermediate support element, the footwell space is fully liberated and no longer divided, while the crossbeam maintains stability through alternative support configurations on the vehicle floor at the A-pillar locations.

This consolidation eliminates the need for a separate central support structure, integrating the stabilization function into the existing A-pillar support architecture.

Inventive Principle:

Principle #5Merging (Combining)

3Stability of the object's composition

If metal pipes with high rigidity are used for the crossbeam, then the crossbeam stability is improved, but the weight of the component increases

Engineering Contradiction:

Improvecrossbeam stabilityVSAvoidcrossbeam weight

Core Design Contradiction:

Stability of the object's compositionVSWeight of moving object

Solution Approach 1:

The invention replaces traditional metal pipe construction with composite material structures for the crossbeam. This substitution maintains the required rigidity and stability while significantly reducing the weight of the component, addressing both the stability and weight concerns simultaneously.

Inventive Principle:

Principle #40Composite materials

AI summary

A front region of a passenger compartment of a motor vehicle, including two mutually opposing A-pillars, a bulkhead which delimits in a longitudinal direction of the motor vehicle, and a crossbeam. The crossbeam extends transversely with respect to the longitudinal direction of the motor vehicle from a first A-pillar of the mutually opposing A-pillars to a second A-pillar of the mutually opposing A-pillars. The crossbeam is supported or mounted exclusively on the mutually opposing A-pillars. The crossbeam is in a form of a die-cast component.
