Rear View Mirror Antenna Module with Sliding Door Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern vehicles face challenges with degraded radio signal reception due to antenna placement, which affects navigation, communication, and toll collection systems, leading to unreliable data services and safety issues, especially when antennas are installed near the front windscreen, obstructing the driver's view and requiring multiple installations for multi-service functionality.
Innovation Solution
A rear view mirror with an integrated antenna module sealing mechanism that exposes the antenna towards the windscreen side when activated, using a slidable or pivotable door mechanism driven by an electromotor, allowing for high-quality radio signal reception and displaying vital information on an electronic display within the mirror, eliminating the need for additional antennas and maintaining driver visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an antenna is installed near the front windscreen for optimal radio signal reception, then the radio signal reception quality is improved, but the driver's view onto the street ahead is obstructed
Solution Approach 1:
The antenna module is integrated into the rear view mirror housing, combining two separate components (antenna and mirror) into a single unit. This allows the antenna to be positioned near the windscreen for optimal signal reception while the mirror housing conceals it from the driver's view, eliminating the harmful effect of obstruction.
Solution Approach 2:
The antenna module is arranged in a recess of the mirror housing and can be hidden inside the housing when not in use. This nesting approach allows the antenna to be stored within the mirror structure, keeping it out of the driver's line of sight while maintaining the ability to deploy it when needed for radio communication.
2Adaptability or versatility
If multiple individual antennas are installed for multiple radio data services, then the radio data service functionality is improved, but the device complexity and installation difficulty increase
Solution Approach 1:
The antenna module is designed as a multi-functional unit capable of supporting multiple radio data services (navigation, communication, entertainment systems) through a single integrated structure. This universal design eliminates the need for multiple separate antennas, reducing installation complexity while maintaining full service functionality.
Solution Approach 2:
Multiple antenna functions for different radio services are merged into a single antenna module that can be installed in one location. This consolidation reduces the number of installation steps and simplifies the overall system while providing support for various radio data services simultaneously.
3Reliability
If an antenna module sealing mechanism with movable door is used to expose the antenna, then the radio signal reception quality is improved, but the device complexity increases
Solution Approach 1:
The antenna module sealing mechanism incorporates a movable door that can transition between open and closed positions. This dynamic structure allows the antenna to be exposed for optimal signal reception when needed while being concealed when not in use, providing adaptability without requiring a completely complex mechanical system.
Solution Approach 2:
The electromotor unit replaces complex manual or mechanical sealing mechanisms with an electrically actuated system. This substitution simplifies the control system while providing reliable operation of the movable door, enabling automatic opening and closing based on operational requirements.
