Solution Overview

Problem

Existing motor vehicle structural components require high labor and time for assembly due to multi-part designs, leading to increased logistics expenses and weight.

Innovation Solution

A one-piece light-metal die-casting structural component that integrates a bulkhead, A-pillars, and transverse reinforcement, eliminating the need for joining processes and allowing for thin-walled, stable construction with integrated features like pedal carriers and ribbing, produced using die casting and potentially enhanced through heat treatment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If multi-part design with separate bulkhead, A-pillars, and transverse reinforcement is used, then structural stability can be achieved, but assembly time and labor cost increase significantly

Engineering Contradiction:
Improvestructural stabilityVSAvoidassembly time
Core Design Contradiction:
Stability of the object's compositionVSLoss of time

Solution Approach 1:

The patent combines the bulkhead, A-pillars, and transverse reinforcement into a single integrated structural component. This merging eliminates the need for separate assembly operations, directly reducing assembly time and labor cost while maintaining structural stability through the integrated design that provides continuous load paths between components.

Inventive Principle:
Principle #5Merging (Combining)

2Strength

If multiple separate components are connected through welding, screwing, or adhesive bonding, then structural integrity is maintained, but manufacturing complexity and cost increase

Engineering Contradiction:
Improvestructural integrityVSAvoidmanufacturing complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The invention integrates multiple structural elements into one monolithic component, eliminating the need for joining processes such as welding, screwing, or adhesive bonding. This merging approach reduces manufacturing complexity by removing multiple assembly steps and quality control requirements for joints, while maintaining structural integrity through the continuous material structure.

Inventive Principle:
Principle #5Merging (Combining)

3Weight of moving object

If thin-walled construction is used, then weight is reduced, but manufacturing difficulty increases for multi-part assemblies

Engineering Contradiction:
Improvecomponent weightVSAvoidmanufacturing ease
Core Design Contradiction:
Weight of moving objectVSEase of manufacture

Solution Approach 1:

The patent employs a monolithic construction approach where the entire structural component is formed as a single piece. This merging enables thin-walled construction to be manufactured more easily because the thin walls are formed in one operation without the need to align and join multiple thin-walled parts, which would be extremely difficult and time-consuming. The integrated design simplifies manufacturing while achieving weight reduction through optimized thin-walled geometry.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A structural component for a motor vehicle is configured to extend transversely to a direction of travel for the motor vehicle and is configured to separate a passenger compartment and a front compartment of the motor vehicle. The structural component includes: a dashboard; two A-pillars arranged in each case laterally with respect to the dashboard; and a transverse reinforcement running along an upper side of the dashboard. The structural component is one-part or a one-piece light-metal die casting.
