Interior Antenna Pedestal Mount for Reduced Vehicle Signal Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle antenna mounts do not effectively prevent signal interference from metal and electronic components, limiting optimal communication performance.
Innovation Solution
A vehicle interior antenna mount system featuring a pedestal mount with a vertical slot and detents, combined with a locking arm that engages the detents to securely hold an antenna module, ensuring it is spaced away from metal components to minimize interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the antenna is mounted close to metal and electronic components, then the device complexity is reduced, but signal interference increases
Solution Approach 1:
The patent introduces a non-conductive mounting structure (pedestal with locking arm) as an intermediary between the antenna and metal components. This mediator physically separates the antenna from harmful electromagnetic interference while maintaining a compact appearance, thus resolving the contradiction between simplicity and signal quality.
Solution Approach 2:
The patent moves the antenna from a two-dimensional surface mounting to a three-dimensional elevated position using the pedestal structure. This vertical displacement creates spatial separation from interfering components without significantly increasing the device's footprint, addressing both complexity and interference concerns.
2Reliability
If the antenna module is securely locked to the pedestal mount, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The locking arm incorporates a self-latching mechanism with detents that automatically secures the antenna module to the pedestal. The spring-loaded arm with engagement protrusions creates a self-service locking system that maintains reliable connection without requiring external fasteners or complex adjustment mechanisms.
3Reliability
If the antenna is isolated from metal components, then signal communication is improved, but the ease of manufacture decreases
Solution Approach 1:
The patent combines the mounting pedestal and locking mechanism into a single integrated component structure. The pedestal with its built-in locking arm and detent system can be manufactured as one piece or pre-assembled unit, simplifying the manufacturing process while maintaining the antenna isolation necessary for good signal communication.

AI summary
A vehicle interior antenna mount system having a pedestal mount extending from a vehicle component in a cabin interior of a vehicle. The pedestal mount has a vertical slot extending from one end and one or more detents, an antenna module housing an antenna, and a locking arm connected to the antenna housing. The locking arm has a rib configured to engage the slot in the pedestal mount, wherein the snap arm includes an engagement portion that engages the at least one detent to lock the antenna housing on the pedestal mount.
