Vehicle Camera Video Routing on OEM Screens Under WiFi Restrictions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Certain vehicles, such as Tesla electric vehicles, impose restrictions on the use of local WiFi signals unless they are connected to the Internet, hindering the installation of after-market devices like cameras that rely on WiFi for communication.
Innovation Solution
A router is installed in the vehicle to receive a wireless signal from a portable device via Bluetooth tethering, generating a local area network and enabling the use of a WiFi signal for after-market devices, transmitting data to a webserver, and allowing access on the OEM screen through an IP address input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a vehicle restricts WiFi usage to only when Internet connection is established, then vehicle security and network stability are improved, but after-market devices relying on WiFi cannot function properly
Solution Approach 1:
The patent introduces a router as an intermediary device that bridges the vehicle's restricted WiFi environment and the after-market camera. The router receives Internet-connected WiFi from the vehicle, creates a separate local area network, and allows the camera to connect locally without requiring direct Internet access. This mediator resolves the contradiction by enabling after-market device functionality while preserving the vehicle's WiFi restrictions.
Solution Approach 2:
The patent segments the network into two distinct parts: the vehicle's Internet-connected WiFi network and a separate local area network for after-market devices. The router divides the network traffic, allowing the camera to operate on the local network without needing Internet connectivity. This segmentation enables after-market device compatibility while maintaining the vehicle's network security policies.
2Object-affected harmful factors
If the vehicle only permits WiFi when Internet connection is available, then network security is improved, but device installation flexibility deteriorates
Solution Approach 1:
The router acts as a security-preserving intermediary that allows after-market devices to install and function without compromising the vehicle's network security. It creates an isolated local network environment where devices can communicate without direct access to the vehicle's Internet-connected WiFi, thus maintaining security while improving installation flexibility.
Solution Approach 2:
The router creates a copy of the WiFi network infrastructure, providing a local area network that mimics WiFi functionality without requiring the vehicle's Internet-connected WiFi. This copying approach allows after-market devices to be installed and operated freely while the original vehicle network security settings remain unchanged.
3Adaptability or versatility
If after-market cameras are installed in vehicles with restricted WiFi, then customization capability is improved, but system complexity increases due to additional routing equipment
Solution Approach 1:
The router performs multiple functions: it acts as a WiFi receiver from the vehicle, creates a local area network for after-market devices, provides Internet sharing when available, and maintains network security. This multi-functionality justifies the added device by consolidating multiple requirements into a single component, reducing overall system complexity despite the added customization capability.
