Projector Beacon Broadcast for Automatic Wireless LAN Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless LAN systems, particularly in ad hoc and infrastructure modes, face inconvenience as users must manually download files from shared servers or perform complex network settings to access shared servers, limiting connectivity and convenience.
Innovation Solution
A wireless LAN system where the projector broadcasts a beacon signal containing its IP address, allowing the terminal to automatically connect via wireless access points without manual network settings, enabling direct access to shared servers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If ad hoc mode is used for wireless communication, then automatic connection settings are achieved, but network isolation prevents access to shared servers
Solution Approach 1:
The patent introduces a wireless access point as an intermediary device that enables the projector to connect to the network infrastructure while maintaining the ad hoc mode's automatic connection benefits. The access point acts as a mediator between the ad hoc network and the wired network, allowing file access without manual configuration.
2Adaptability or versatility
If infrastructure mode is used for wireless communication, then network access capability is improved, but manual network settings are required
Solution Approach 1:
The patent implements self-service by having the projector automatically obtain network configuration parameters (IP address, subnet mask, gateway) through DHCP protocol. The system performs its own network setup without requiring user intervention, combining infrastructure mode's network access with automatic configuration.
3Reliability
If manual file download is required before wireless communication, then network security is maintained, but user convenience is reduced
Solution Approach 1:
The patent applies preliminary action by establishing the wireless connection and network configuration before any file transfer operations. The projector automatically joins the network, obtains IP addressing, and prepares the communication channel in advance, allowing immediate file access without requiring users to pre-download files.
