Vehicle Window Decoration Assembly With Flush Seal Transition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle window decorations often have a step difference at the joint with the encapsulation material, resulting in an inconsistent appearance that fails to meet customer aesthetic demands due to manufacturing tolerances and material color mismatches.
Innovation Solution
A vehicle window assembly design featuring a transparent plate, a seal, and a decoration with mating portions that form a continuous transition, utilizing protrusions and tongue edges for self-adaptive attachment to compensate for mounting tolerances and ensure a flush appearance, with the seal's tongue edges being deformable to accommodate dimensional variations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the bright decoration is mounted on the vehicle window glass with encapsulation material, then the decorative and wind shielding function is improved, but a step difference appears at the joint between the decoration and encapsulation material
Solution Approach 1:
The patent integrates the decoration and encapsulation material into a unified structure where the decoration is embedded within the encapsulation material. The first mating portion of the decoration fits into the second mating portion of the encapsulation material, creating a merged structure that eliminates the step difference at the joint while maintaining both decorative and wind shielding functions.
Solution Approach 2:
The decoration is nested within the encapsulation material structure. The mating portions create a nested configuration where the decoration's first mating portion is received by the encapsulation material's second mating portion, allowing the decoration to be contained within the overall assembly without creating surface discontinuities.
2Strength
If the bright decoration is made of metal or alloy material, then the appearance quality and anti-rust performance are improved, but the appearance color is inconsistent with the encapsulation material
Solution Approach 1:
The patent applies different material properties to different parts of the assembly. The decoration uses metal or alloy material for strength and anti-rust performance, while the encapsulation material provides a different appearance. The mating portions are designed to create visual continuity, where the encapsulation material wraps around and conceals the joints of the metal decoration, harmonizing the appearance of different materials.
3Ease of manufacture
If the encapsulation material is used to wrap the decoration, then the mounting function is improved, but manufacturing precision is reduced due to mounting tolerances
Solution Approach 1:
The patent designs the mating portions with specific dimensional parameters that accommodate mounting tolerances. The first mating portion of the decoration and the second mating portion of the encapsulation material are designed with complementary dimensions that allow for variation while maintaining proper fit. This parameter-based design enables easy mounting while achieving precise joint alignment despite manufacturing tolerances.
