Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for projecting a mobile device's image to a screen are limited by the need for manual SSID and password setup for WiFi connections and are restricted by short USB cable lengths, making long-distance projection inconvenient.
Innovation Solution
A mobile device connection device with a USB port and a communication module for wireless communication with a WiFi access point, enabling instant plugging and unplugging and overcoming distance limitations through wireless connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If WiFi connection with manual SSID and password setup is used, then wireless projection is achieved, but operation complexity increases and setup time is extended
Solution Approach 1:
The receiver is pre-configured with WiFi connection parameters and stored in the storage module. When a mobile device is connected via USB, the system automatically retrieves and applies the pre-stored WiFi settings, eliminating the need for manual SSID and password input during each connection event.
Solution Approach 2:
The system performs automatic connection establishment by itself. The processor automatically configures WiFi parameters, establishes wireless connections, and manages the projection process without requiring user intervention for manual setup, making the system serve itself.
2Reliability
If USB cable connection is used, then stable connection is achieved, but connection distance is limited to 1-2 meters
Solution Approach 1:
The system merges USB wired connection for data transmission with WiFi wireless connection for power and control signals. The mobile device connects to the receiver via USB cable for stable data transfer, while simultaneously establishing a WiFi connection for power supply and device control, combining the advantages of both connection methods.
Solution Approach 2:
The receiver acts as an intermediary device between the mobile device and the projection system. It receives data from the mobile device via USB, processes the data, and outputs to the projector, enabling stable long-distance connection by mediating the connection between the mobile device and the projection system.
3Ease of operation
If manual WiFi configuration is required for each device, then network security is maintained, but user convenience deteriorates
Solution Approach 1:
WiFi network parameters including SSID and password are pre-configured and stored in the storage module before actual use. When projection is needed, the system automatically retrieves these pre-stored parameters and establishes connection without requiring users to manually configure network settings each time.
Solution Approach 2:
The receiver is designed to work with multiple different mobile devices simultaneously. By storing WiFi parameters and automatically configuring connections, the system provides universal compatibility across different device types while maintaining network security through pre-configured authentication parameters.
