Solution Overview

Problem

Existing vehicle front end designs with air duct devices are costly to produce and assemble, as they require coordinating and connecting multiple separate parts, which increases manufacturing and assembly expenses.

Innovation Solution

A vehicle front end element with an opening leading to an air duct device, where the air duct device is formed by two segments connected by an integral hinge, allowing for a one-piece molded part that can be easily assembled by swiveling and fixing the segments, reducing production and assembly costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple separate parts are used to form the air duct device, then the device can be assembled from modular components, but the production costs and assembly costs increase due to coordination and connection requirements

Engineering Contradiction:
Improvemodular assembly capabilityVSAvoidproduction cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent merges multiple separate air duct parts into a single integrated air duct device that is molded as one piece. This eliminates the need for coordinating and connecting multiple separate parts, thereby reducing both production costs and assembly costs while maintaining the functional requirements of the air duct system

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If multiple separate parts are used to form the air duct device, then the device can be assembled from modular components, but the assembly complexity increases due to coordination and connection requirements

Engineering Contradiction:
Improvemodular assembly capabilityVSAvoidassembly complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple air duct segments into a single molded part, eliminating the need for complex coordination and connection operations during assembly. The integrated design reduces assembly complexity while preserving the modular functionality needed for installation and maintenance

Inventive Principle:
Principle #5Merging (Combining)

3Ease of manufacture

If a single integrated air duct device is used, then production costs and assembly costs are reduced, but the device may be difficult to manufacture as a one-piece molded part

Engineering Contradiction:
Improveproduction costVSAvoidmolding complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent applies segmentation in the mold design rather than in the final product. The molding process is divided into multiple injection stages that form different sections of the air duct device sequentially, allowing complex geometries to be created as a one-piece part while maintaining manufacturing feasibility

Inventive Principle:
Principle #1Segmentation

4Ease of operation

If a single integrated air duct device is used, then assembly is simplified, but the manufacturing process becomes more challenging

Engineering Contradiction:
Improveassembly simplicityVSAvoidmanufacturing difficulty
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The manufacturing process is segmented into multiple injection molding stages, where each stage forms a specific section of the air duct device. This allows the complex one-piece part to be manufactured systematically while maintaining assembly simplicity in the final product

Inventive Principle:
Principle #1Segmentation
