Solution Overview

Problem

Existing solutions for mounting a heat exchanger assembly in a motor vehicle require separate support structures for different longitudinal positions, leading to high production costs and low flexibility, as they necessitate designing and producing multiple components for various powertrain configurations.

Innovation Solution

A motor vehicle front-end design that includes a flexible frame with interchangeable brackets and positioning guides, allowing the heat exchanger assembly to be positioned forward or rearward without altering the frame's structure, using wedges and plugs to secure the assembly in two different configurations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional front-end with separate headlight units and grille is used, then the design flexibility is limited and production time is increased, but the manufacturing precision and assembly complexity remain manageable

Engineering Contradiction:
Improvedesign flexibilityVSAvoidassembly complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges the headlight units, grille, and bumper into a single integrated front-end assembly. The headlight units are positioned in recesses of the bumper, and the grille is integrated between them, creating a unified structure that reduces the number of separate components and simplifies assembly while enabling greater design flexibility

Inventive Principle:
Principle #5Merging (Combining)

2Productivity

If a conventional front-end with multiple separate components is used, then the production time is increased due to sequential assembly, but the manufacturing precision can be maintained for each individual component

Engineering Contradiction:
Improveproduction timeVSAvoidintegration complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The front-end assembly is designed as an integrated unit where the bumper serves as the base structure, headlight units are pre-positioned in recesses, and the grille is integrated between them. This merging of components into a single assembly reduces the number of sequential assembly steps and improves production efficiency

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If larger headlight units are used to improve safety visibility, then the safety performance is improved, but the available space in the front-end design is reduced

Engineering Contradiction:
Improvesafety visibilityVSAvoidavailable front-end space
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The headlight units are positioned in recesses of the bumper, utilizing the depth dimension rather than only the surface area. This allows larger headlight units to be accommodated within the available space by exploiting the three-dimensional structure of the front-end assembly

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
