Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing antenna assemblies for vehicles face logistical and installation challenges due to the need for unique designs to fit specific vehicle roof curvatures, leading to issues with achieving a zero-gap fit and reducing installation errors and costs.
Innovation Solution
The use of a resiliently compliant connection mechanism between the outer cosmetic cover and the antenna base module, featuring snap clip members and latching members that adjust to conform to different vehicle body wall shapes, allowing for a common antenna base module to fit various vehicle curvatures and reducing installation errors and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a unique antenna cover is designed to fit each specific vehicle roof curvature, then a zero-gap fit is achieved, but device complexity and manufacturing costs increase
Solution Approach 1:
The patent applies universality by designing a single antenna base module that can fit multiple vehicle roof curvatures through the compliant latching mechanism. The snap clip members and latching members allow the same base module to adapt to different vehicle models without requiring unique covers for each curvature, thereby reducing device complexity while maintaining the zero-gap fit aesthetic.
Solution Approach 2:
The patent employs parameter changes by making the latching mechanism compliant and flexible. The snap clip members and latching members are designed to be resiliently flexible, allowing them to deform and adapt to different roof curvatures. This flexibility in the latching mechanism parameters enables a single base module design to achieve proper fit across multiple vehicle models with varying roof shapes.
2Manufacturing precision
If a unique antenna cover is designed for each vehicle roof curvature, then proper fit is achieved, but installation time and productivity decrease
Solution Approach 1:
The universal base module design with compliant latching allows installers to use the same component across different vehicle models, eliminating the need to identify and select from multiple cover types. This universality streamlines the installation process and improves productivity while maintaining proper fit through the adaptive latching mechanism.
Solution Approach 2:
The compliant latching mechanism provides self-adjusting functionality during installation. The resilient snap clip members and latching members automatically deform and conform to the specific vehicle roof curvature during the installation process, eliminating the need for precise pre-alignment or complex installation procedures. This self-service capability reduces installation time while ensuring proper fit.
3Shape
If a unique antenna cover is designed for each vehicle roof curvature, then aesthetic appearance is improved, but logistical complexity increases
Solution Approach 1:
The patent resolves logistical complexity by designing a universal base module that maintains aesthetic appearance across different vehicle models. Instead of managing inventories of multiple unique cover styles and colors, the system uses a single base module design that adapts to various curvatures through its compliant latching mechanism, thereby simplifying logistics while preserving the desired aesthetic appearance.
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
This solution enables a zero-gap fit between the antenna assembly and the vehicle body wall, accommodating various roof curvatures with a single base module design, reducing installation errors and logistical complexities while maintaining a perfect fit and aesthetic appearance.
Implementation Method 1
The snap clip members and latching members are resiliently flexible and configured for forming a resiliently compliant connection therebetween. Accordingly, the snap clip members and latching members, when engaged, are movable in response to the abutment of and pressure applied by the lower edge of the outer cosmetic cover against the vehicle body wall.

AI summary
An antenna assembly generally includes an antenna module mountable to a vehicle body wall. The antenna base module includes a base, a protective cover coupled to the base, at least one antenna element disposed within an interior enclosure collectively defined by the protective cover and the base, and one or more latching members. An outer cosmetic cover has one or more snap clip members engageable with the one or more latching members when the outer cosmetic cover is positioned generally over the protective cover. The snap clip members and latching members are resiliency flexible and configured for forming a resiliency compliant connection therebetween. In a final installed position of the antenna assembly to the vehicle body wall, the lower edge of the outer cosmetic cover conforms against the vehicle body wall substantially without any gap therebetween.
