Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle window moldings face issues with position deviations due to manufacturing tolerances, leading to gaps and steps between the molding and the sheet metal, requiring additional mounting accessories and complicating the installation process.
Innovation Solution
A vehicle window assembly with a self-adjusting molding that includes a first insert movably mounted on an encapsulation, featuring elastic portions that generate pre-tightening forces to adjust the molding's position, allowing it to attach securely to the sheet metal, utilizing sliding or rotating mechanisms to compensate for manufacturing tolerances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the molding is rigidly fixed to the encapsulation, then the structure is simple and stable, but position deviations due to manufacturing tolerances cause gaps and steps between the molding and sheet metal
Solution Approach 1:
The patent applies the dynamics principle by transforming the rigid fixed connection into a movable adjustable connection. The first insert is designed to slide along the side wall of the encapsulation, allowing the molding to dynamically adjust its position to compensate for manufacturing tolerances and achieve seamless fitting with the sheet metal.
Solution Approach 2:
The patent applies parameter changes by introducing an elastic portion that can be compressed to generate pre-tightening force. This changes the mechanical state of the connection from static to actively adjustable, enabling the molding to maintain precise positioning despite variations in manufacturing dimensions.
2Manufacturing precision
If additional mounting accessories are used to compensate for position deviations, then the fitting precision is improved, but the mounting process becomes more complex and time-consuming
Solution Approach 1:
The patent applies self-service by designing the first insert with sliding capability along the side wall of the encapsulation. This allows the molding to automatically adjust and compensate for position deviations without requiring additional mounting accessories or complex adjustment operations, thereby reducing installation time and simplifying the mounting process.
3Manufacturing precision
If the molding is made adjustable to compensate for tolerances, then the fitting precision is improved, but the structure becomes more complex
Solution Approach 1:
The patent applies segmentation by dividing the mounting structure into distinct functional components: the encapsulation, the first insert with sliding capability, and the molding. This modular segmentation allows each component to perform its specific function while maintaining overall structural simplicity and enabling precise adjustment without excessive complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The self-adjusting molding automatically compensates for manufacturing tolerances, ensuring a seamless fit without gaps or steps, simplifying the mounting process and maintaining a smooth appearance.
Implementation Method 1
An elastic portion is disposed at an abutting position of the first insert and a side wall of the encapsulation. The elastic portion is pressed to generate a pre-tightening force

AI summary
A vehicle window assembly is provided. The vehicle window assembly includes a glass pane, an encapsulation fixed to an edge of the glass pane, a first insert mounted on the encapsulation, and a molding mounted on the first insert. The first insert is movably mounted on the encapsulation. An elastic portion is disposed at an abutting position of the first insert and a side wall of the encapsulation. The vehicle window assembly is configured to be mounted on a sheet metal. When the vehicle window assembly is mounted on the sheet metal, the side wall of the encapsulation faces the sheet metal. The elastic portion is pressed to generate a pre-tightening force that makes the first insert move towards the sheet metal, to drive the molding and make the molding be attached to the sheet metal.
