Vehicle Camera Peripheral Wireless Power and Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle camera systems require professional installation and are not easily usable with iOS devices due to limitations in background app functionality, necessitating user input to display camera video, which can be inconvenient for drivers.
Innovation Solution
A vehicle camera peripheral system that uses Bluetooth Low Energy (BLE) for wireless communication with smartphones, allowing for battery-powered operation and user-activated triggering, enabling efficient power management and minimal user interaction for camera activation, even on iOS devices, through a separate activation unit or app that detects user input without requiring the app to run in the foreground.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wired installation is used to power the camera from vehicle electrical system, then the camera can be reliably powered and triggered, but the installation complexity increases and requires professional installer
Solution Approach 1:
The patent replaces the mechanical/wired power connection system with a wireless power transmission system using Bluetooth Low Energy (BLE) technology. The camera peripheral communicates wirelessly with the smartphone, eliminating the need for physical wiring through the vehicle's electrical system while maintaining reliable power supply and triggering functionality through wireless communication protocols.
Solution Approach 2:
The patent introduces a smartphone as an intermediary device that mediates between the power source and the camera peripheral. The smartphone runs a background application that receives wireless signals, processes power commands, and controls the camera peripheral's operation, thereby eliminating the need for direct wired connection to the vehicle's electrical system.
2Ease of operation
If the app runs in foreground to display video, then the video can be displayed, but the user interaction requirement increases and convenience decreases
Solution Approach 1:
The patent implements preliminary action by keeping the application running in the background before it is actually needed. The background application continuously monitors for wireless signals and is pre-positioned to immediately display video when triggered, eliminating the need for users to manually launch the app from the foreground while maintaining video display readiness.
Solution Approach 2:
The patent ensures continuity of useful action by maintaining the application in a persistent background state that continuously monitors for activation signals. This allows the system to transition seamlessly from background monitoring to foreground video display without interruption or manual user intervention, keeping the useful function (video display capability) continuously available.
