Solution Overview

Problem

The existing window glass assemblies and switch key assemblies in vehicles are separately designed, making it difficult to meet the requirements of original equipment manufacturers for high integration and convenient installation.

Innovation Solution

A window glass assembly with a through hole, a connecting member, a bracket assembly, and a switch key assembly integrated through the connecting member, allowing for improved integration and ease of installation by injection molding or adhesive bonding.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the window glass assembly and switch key assembly are separately designed, then each component can be optimized independently, but the integration level and installation convenience deteriorate

Engineering Contradiction:

Improveintegration levelVSAvoidnumber of separate components

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the window glass assembly and switch key assembly into a single integrated unit. The switch key assembly is mounted on a bracket that is connected to the glass panel through a connecting member, merging two previously separate components into one integrated assembly that is pre-assembled and ready for installation.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The integrated assembly serves multiple functions: the glass panel provides the window function while the mounted switch key assembly provides control functions. This multi-functional integration allows a single component to replace multiple separate parts, improving both integration level and installation convenience.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Volume of moving object

If the connecting member is positioned close to the through hole for compact design, then the overall size is reduced, but the risk of glass cracking increases

Engineering Contradiction:

Improveoverall assembly sizeVSAvoidglass cracking risk

Core Design Contradiction:

Volume of moving objectVSReliability

Solution Approach 1:

The patent introduces a blocking member as an intermediary element positioned between the connecting member and the through hole. This blocking member acts as a mediator that prevents stress concentration at the hole edge while still allowing the connecting member to be positioned relatively close to the through hole, thus maintaining compact size while reducing glass cracking risk.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The blocking member provides beforehand cushioning by being positioned in advance between the connecting member and the through hole. It cushions and distributes the stress that would otherwise concentrate at the hole edge, preventing glass cracking before it can occur during installation or use.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

3Productivity

If injection molding is used to integrally form the connecting member for efficient manufacturing, then production efficiency is improved, but the complexity of the molding process increases

Engineering Contradiction:

Improvemanufacturing efficiencyVSAvoidmolding process complexity

Core Design Contradiction:

ProductivityVSEase of manufacture

Solution Approach 1:

The patent segments the injection molding process into two separate stages: first molding the connecting member, and then molding the blocking member. This segmentation of the molding process reduces the complexity of each individual molding operation while maintaining high production efficiency, as each molding step can be optimized independently.

Inventive Principle:

Principle #1Segmentation

AI summary

The present application relates to a window glass assembly and a vehicle. The window glass assembly comprises: a glass plate, a connecting member, a support assembly, and a switch button assembly. A through hole running through the glass plate in the thickness direction of the glass plate is formed in the glass plate. The connecting member is fixedly provided on the plate surface of the glass plate around the circumference of the through hole. The support assembly is connected to the connecting member. The switch button assembly is mounted on the support assembly, and a button of the switch button assembly passes through the through hole.
