Vehicle Window Decoration Structure Without Plastic Insert Reinforcement

Solution Overview

Problem

The existing vehicle window structures using stainless steel decoration trims require additional plastic inserts to enhance strength, increasing manufacturing complexity and cost.

Innovation Solution

A vehicle window structure with a decoration part that includes a reinforcing portion extending into the encapsulation, providing support without the need for additional plastic inserts, by integrating the body, embedded, and reinforcing portions through stamping, allowing the reinforcing portion to overlap or be parallel to the glass for enhanced support.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If plastic inserts are added to enhance the strength of the encapsulation, then the strength is improved, but the process complexity and manufacturing cost increase

Engineering Contradiction:

Improvestrength of encapsulationVSAvoidprocess complexity

Core Design Contradiction:

StrengthVSDevice complexity

Solution Approach 1:

The patent combines the reinforcement function with the decoration part by integrating a reinforcing portion into the decoration trim structure. The reinforcing portion is formed as an integral part of the decoration trim through stamping, eliminating the need for separate plastic inserts while maintaining encapsulation strength.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The decoration part is designed to serve multiple functions: aesthetic decoration and structural reinforcement. The reinforcing portion of the decoration trim simultaneously provides visual appeal and mechanical support to the encapsulation, making the decoration part a multi-functional component.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Strength

If plastic inserts are added to enhance the strength of the encapsulation, then the strength is improved, but the manufacturing cost increases

Engineering Contradiction:

Improvestrength of encapsulationVSAvoidmanufacturing cost

Core Design Contradiction:

StrengthVSEase of manufacture

Solution Approach 1:

The patent combines the reinforcement function with the decoration part by integrating a reinforcing portion into the decoration trim structure. The reinforcing portion is formed as an integral part of the decoration trim through stamping, eliminating the need for separate plastic inserts while maintaining encapsulation strength.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The reinforcing portion is made from the same metal material as the decoration trim (stainless steel or aluminum alloy), utilizing existing materials rather than requiring additional plastic inserts. This approach reduces material costs and simplifies the manufacturing process.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

3Strength

If the reinforcing portion extends into the encapsulation to provide support, then the structural strength is enhanced, but the device complexity increases

Engineering Contradiction:

Improvestructural strengthVSAvoidstructure complexity

Core Design Contradiction:

StrengthVSDevice complexity

Solution Approach 1:

The patent combines the reinforcement function with the decoration part by integrating a reinforcing portion into the decoration trim structure. The reinforcing portion is formed as an integral part of the decoration trim through stamping, eliminating the need for separate plastic inserts while maintaining encapsulation strength.

AI summary

A vehicle window structure includes a vehicle window glass, a decoration part and an encapsulation connecting the vehicle window glass with the decoration part. The decoration part includes a body portion for decoration purpose and an embedded portion connected with the body portion and embedded into the encapsulation. The decoration part further includes a reinforcing portion formed by at least a portion of the embedded portion extending inside the encapsulation.
