Vehicle Roof Antenna Module Spring Latching Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing antenna module installation systems for vehicle roofs are complex, require tools, and do not allow non-destructive dismantling, with designs that are often complicated and difficult to install.
Innovation Solution
An antenna module with a spring element that can be latched and secured via a locking element, allowing for simple installation and tool-free operation, where the locking element can be actuated from the same side as the antenna module's arrangement, and is releasable for non-destructive dismantling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional screwing or latching systems are used to fasten the antenna module to the vehicle roof, then the antenna module can be securely fastened, but the installation becomes complex and requires tools
Solution Approach 1:
The spring element automatically engages with the vehicle roof opening when the antenna module is inserted, providing self-latching without requiring manual intervention or tools. The spring force automatically secures the antenna module in place
Solution Approach 2:
The traditional mechanical screwing system is replaced with an elastic spring element that uses spring force instead of threaded fastening. This substitution eliminates the need for screwdrivers and complex mechanical fastening mechanisms
2Reliability
If traditional latching systems with multiple components are used, then the antenna module can be fastened securely, but the design becomes complicated
Solution Approach 1:
The spring element combines multiple functions into a single component: it provides latching engagement, applies securing force, and enables tool-free operation. This merging eliminates the need for separate latches, screws, and fastening mechanisms
Solution Approach 2:
The spring element serves multiple purposes simultaneously: it acts as a latching mechanism, a fastening device, and a securing element. This multi-functionality reduces the overall number of components needed in the fastening system
3Reliability
If traditional fastening systems are used, then the antenna module can be installed, but non-destructive dismantling is not possible
Solution Approach 1:
The spring element provides a dynamic fastening system that can be easily reversed. By releasing the spring force, the antenna module can be removed without damage to the vehicle roof or the module itself, enabling non-destructive dismantling and replacement
4Reliability
If complex installation systems requiring tools are used, then the antenna module can be fastened securely, but the installation time and effort increase
Solution Approach 1:
The spring element is pre-loaded with elastic energy during manufacturing, so no additional fastening actions are needed during installation. The antenna module is simply inserted and the spring automatically engages, eliminating time-consuming screwing or latching operations
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
Enables a one-handed, tool-free, and simple installation of the antenna module at the vehicle roof opening, with the ability to securely fasten and release the module without damaging the installation, reducing the complexity and effort required for installation and maintenance.
Implementation Method 1
a spring element (13), in particular a resilient element, with which the antenna module (1) can be latched
Data Source
AI summary
The present disclosure relates to an antenna module for installing at an opening of a vehicle roof, wherein the antenna module can be arranged at the opening and can be latched there via at least one spring element, wherein the fastening of the antenna module can be secured to the vehicle roof via a locking element which, in its locking position, blocks a resilient backward movement of the spring element out of the latched position.
