Solution Overview

Problem

Existing aluminum alloy guide rails for vehicle windows are costly, have low assembly efficiency, and are prone to water leakage, affecting the use experience of manufacturers and customers.

Innovation Solution

A vehicle window assembly design that integrates the glass plate, mounting member, and connecting member structurally, allowing for efficient assembly by disposing the mounting member in an accommodating space defined by the guide rail, which reduces connecting gaps and enhances waterproof performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional separate-component guide rails are used, then assembly flexibility is maintained, but assembly efficiency is low and water leakage occurs

Engineering Contradiction:
Improveassembly efficiencyVSAvoidwaterproof performance
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent merges the guide rail, mounting member, and connecting member into an integrated aluminum alloy guide rail structure. The guide rail directly integrates the mounting function (through built-in mounting holes) and connecting function (through built-in connecting members), eliminating the need for separate components. This integration reduces the number of assembly steps and connection interfaces, thereby improving assembly efficiency while reducing water leakage paths through fewer joints.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of manufacture

If multiple separate components are assembled, then structural adaptability is maintained, but assembly complexity increases and cost rises

Engineering Contradiction:
Improvemanufacturing costVSAvoidassembly complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent combines multiple separate components (guide rail, mounting member, connecting member) into a single integrated aluminum alloy guide rail. This merging reduces the total number of parts that need to be manufactured, stored, and assembled, thereby reducing manufacturing costs and assembly complexity while maintaining the necessary structural adaptability through the integrated design.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated aluminum alloy guide rail performs multiple functions simultaneously: it provides guidance, mounting, and connecting functions. The guide rail includes built-in mounting holes for securing the glass plate and built-in connecting members for joining to the door triangle, allowing a single component to replace multiple specialized parts, thereby simplifying the overall assembly.

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

3Reliability

If traditional guide rails with multiple joints are used, then installation flexibility is maintained, but waterproof performance deteriorates due to more connection gaps

Engineering Contradiction:
Improvewaterproof performanceVSAvoidinstallation flexibility
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent integrates the mounting and connecting functions directly into the guide rail structure, reducing the number of separate joints and connection interfaces. The integrated design minimizes the number of gaps where water could penetrate, thereby improving waterproof performance while maintaining installation flexibility through the guide rail's inherent design features.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A vehicle window assembly and a vehicle are provided in the present disclosure. A guide rail defines an accommodating space that has an opening facing a glass plate. A mounting member defines a mounting hole in communication with the accommodating space. The connecting member has one end connected to the glass plate, and the other end penetrating through the mounting hole. Therefore, the glass plate, the connecting member, and the mounting member can be structurally integrated, which is beneficial to improving structural stability of the glass plate, the connecting member, and the mounting member. On this basis, only by disposing at least part of the mounting member in the accommodating space, assembly between the guide rail and the glass plate, the connecting member, and the mounting member can be realized, thereby effectively improving assembly efficiency of the vehicle window assembly. In addition, since the glass plate, the connecting member, and the mounting member are structurally integrated, connecting gaps between various components of the vehicle window assembly can be further reduced, and moisture is prevented from entering through joints, which is beneficial to improving a waterproof performance of an internal structure of the vehicle window assembly, thereby improving quality of the vehicle window assembly.
