Vehicle Glazing Antenna Plate With Flush Seal Geometry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle glazing configurations with antenna plates and profiled seal portions suffer from dirt accumulation and acoustic noise due to clearance and sharp angles, compromising maintenance and aerodynamic performance.
Innovation Solution
Achieving a double flush surface continuity between the glazed element and antenna plate, with rounded corners and a hollow in the profiled seal portion to facilitate water and dirt evacuation, while integrating the antenna plate seamlessly into the profiled joint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the antenna plate enters the profiled seal portion at an acute angle with clearance, then the manufacturing is simpler, but dirt accumulates and acoustic noise is generated
Solution Approach 1:
The patent applies curvature by rounding the angles where the antenna plate meets the profiled seal portion. Instead of sharp acute angles, the design incorporates rounded corners that facilitate smooth airflow and prevent dirt accumulation. This curved geometry eliminates the harmful sharp edges while maintaining the functional relationship between components.
2Object-affected harmful factors
If a double flush surface continuity is achieved between glazed element and antenna plate, then dirt evacuation and noise reduction are improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent applies local quality by creating a hollow depression in the profiled seal portion at the specific location where it meets the antenna plate. This localized geometric feature facilitates dirt and water evacuation without requiring high precision across the entire assembly. The hollow acts as a dedicated zone for managing contaminants while the rest of the assembly can tolerate normal manufacturing tolerances.
3Stability of the object's composition
If the antenna plate is integrated into the profiled seal portion with external part extending outside, then the structural integration is improved, but the complexity of achieving surface continuity increases
Solution Approach 1:
The patent applies segmentation by dividing the antenna plate into two distinct parts: a fixing part that is integrated into the profiled seal portion, and an external part that extends outside. This segmentation allows each part to be optimized independently - the fixing part for structural integration and the external part for functional purposes - while simplifying the achievement of surface continuity at the interface.
