Solution Overview

Problem

Existing flush/smooth sealing structures in motor vehicles face implementation difficulties due to complex designs, leading to tolerance management issues and increased costs, primarily in the x-direction fixation of vehicle glass.

Innovation Solution

A sealing profile with a hook and pillar structure that simplifies the sealing process, utilizing components like glass guides, positioning lips, and isolation lips to ensure effective sealing against dust and noise, while maintaining a flush surface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If complex sealing structures are used to achieve flush/smooth sealing, then sealing performance is improved, but device complexity and manufacturing difficulty increase

Engineering Contradiction:
Improvesealing performanceVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The sealing profile is divided into distinct functional segments: a hook figure portion for lateral (x-direction) fixation, a pillar portion for vertical positioning, and a sealing portion for dust and liquid prevention. This segmentation allows each component to perform its specific function efficiently without requiring an overly complex integrated structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The hook figure and pillar structures are integrated within the sealing profile cross-section, with the hook figure forming part of the profile body and the pillar portion extending from it. This nested arrangement achieves multiple sealing and fixation functions within a unified structure, reducing overall complexity while maintaining effective sealing performance.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Reliability

If complex sealing structures are used to achieve flush/smooth sealing, then sealing performance is improved, but manufacturing cost and production difficulty increase

Engineering Contradiction:
Improvesealing performanceVSAvoidmanufacturing ease
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The invention combines the hook figure for lateral fixation, the pillar for vertical positioning, and the sealing elements into a single integrated sealing profile that can be produced as one piece. This merging of functions into a unified component simplifies manufacturing processes, reduces assembly steps, and lowers production costs while maintaining effective sealing performance.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The sealing profile serves multiple functions simultaneously: the hook figure provides x-direction fixation, the pillar provides positioning, and the integrated structure provides sealing against dust and liquids. This multi-functionality eliminates the need for separate components, simplifying both manufacturing and assembly processes.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Stability of the object's composition

If traditional sealing structures are used, then glass fixation is achieved, but flush/smooth surface form cannot be established

Engineering Contradiction:
Improveglass fixationVSAvoidsurface form
Core Design Contradiction:
Stability of the object's compositionVSShape

Solution Approach 1:

The sealing profile applies different structural characteristics at different locations: the hook figure provides lateral restraint for fixation stability, while the external flush lip creates a smooth outer surface. This local differentiation of structural quality allows simultaneous achievement of glass fixation and flush surface form without compromising either function.

Inventive Principle:
Principle #3Local quality
