Vehicle Wi-Fi Router With Switchable Inside-Outside Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle communication systems lack the ability to dynamically adjust Wi-Fi coverage between interior and exterior spaces, limiting flexibility and user convenience.
Innovation Solution
A communication system for vehicles with a dual-housing configuration, incorporating a router, antennas, and a switchable antenna selection module that allows users to select between interior, exterior, or combined Wi-Fi coverage states, utilizing a tri-state switch arrangement for seamless connectivity adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single fixed antenna configuration is used, then device complexity is reduced, but Wi-Fi coverage adaptability is limited
Solution Approach 1:
The system implements dynamic antenna configuration through a switch module that allows real-time selection between different antenna states (inside vehicle only, outside vehicle only, or both). This enables the Wi-Fi coverage to adapt dynamically to different operational scenarios without permanently increasing structural complexity.
Solution Approach 2:
The antenna system is designed with multi-functionality, where the same antenna infrastructure serves multiple purposes: inside vehicle coverage, outside vehicle coverage, and combined coverage. The switch module enables a single antenna system to fulfill multiple coverage requirements, improving versatility without proportionally increasing complexity.
2Adaptability or versatility
If multiple antenna configurations are provided, then Wi-Fi coverage versatility is improved, but ease of operation deteriorates
Solution Approach 1:
The switch module provides dynamic control over antenna configuration, allowing users to select from three distinct coverage states (inside only, outside only, or both). This dynamic switching capability maintains ease of operation by presenting a simplified user interface despite the underlying complexity of multiple antenna configurations.

AI summary
A vehicle communication system comprises a first housing configured to be mounted inside the vehicle and a second housing configured to be mounted outside of the vehicle. A router is coupled to a first electronics module and an antenna selection module. The router, first electronics module, and antenna selection module are disposed in the first housing. A first Wi-Fi antenna is disposed in the first housing and coupled to the antenna selection module. A second Wi-Fi antenna is disposed in the second housing and coupled to the antenna selection module. A modem is disposed in the first housing or the second housing and coupled to the router. The antenna selection module comprises a switch operable by a user of the communication system for selecting between a plurality of Wi-Fi coverage states including an inside vehicle coverage state, an outside vehicle coverage state, and an inside and outside vehicle coverage state.
