Vehicle Window Trim Encapsulation Without Plastic Inserts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of stainless steel decoration trims in vehicle windows requires additional plastic inserts for strength enhancement, increasing process complexity and manufacturing costs.
Innovation Solution
A vehicle window structure with a decoration part that includes a body portion, an embedded portion, and a reinforcing portion, where the reinforcing portion extends inside the encapsulation and overlaps the window glass by at least 5 mm, providing support without the need for plastic inserts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional vehicle window structure with separate waterproof rubber and decorative rubber is used, then the manufacturing process is simple, but water may penetrate into the window groove and cause rusting of the window lift motor
Solution Approach 1:
The patent combines the waterproof rubber and decorative rubber into a single integrated component. The decorative rubber includes an L-shaped groove structure that accommodates the waterproof rubber, merging two separate sealing functions into one unified part. This eliminates the interface between separate components where water could penetrate, while maintaining both waterproofing and aesthetic functions.
Solution Approach 2:
The waterproof rubber is nested within the L-shaped groove of the decorative rubber. This nested configuration allows the waterproof rubber to be positioned precisely within the window groove while being protected and held by the decorative rubber structure, ensuring reliable sealing without requiring separate attachment mechanisms.
2Shape
If a conventional vehicle window structure with separate waterproof rubber and decorative rubber is used, then the production cost is low, but the aesthetic appearance is poor due to visible gaps and seams
Solution Approach 1:
By merging the waterproof rubber and decorative rubber into a single integrated component, the patent eliminates visible gaps and seams at the interface between separate parts. The L-shaped groove structure of the decorative rubber provides a continuous surface that conceals the waterproof rubber, creating a seamless and aesthetically pleasing appearance.
Solution Approach 2:
The decorative rubber is designed with different functional zones: the outer surface provides aesthetic appearance, while the L-shaped groove provides structural support and positioning for the waterproof rubber. This local differentiation of quality allows the same component to fulfill both cosmetic and functional requirements.
3Reliability
If a conventional vehicle window structure with separate waterproof rubber and decorative rubber is used, then the installation process is simple, but water can penetrate through the interface between components into the window groove
Solution Approach 1:
The integration of waterproof rubber and decorative rubber into a single component eliminates the interface where water penetration occurs in conventional designs. The L-shaped groove structure provides an inherent sealing mechanism that prevents water from reaching the window groove, ensuring reliable waterproofing without requiring complex multi-step installation procedures.
Solution Approach 2:
The waterproof rubber is pre-positioned within the L-shaped groove of the decorative rubber during manufacturing. This preliminary positioning ensures that the waterproofing function is already established before installation, eliminating the need for complex alignment and sealing procedures during vehicle assembly.
